Description

Nginx is a popular web server that can also be used as a reverse proxy, load balancer, and http cache.

First steps with the Bitnami Nginx Stack

Welcome to your new Bitnami application running on Amazon Web Services! Here are a few questions (and answers!) you might need when first starting with your application.

What credentials do I need?

You need two sets of credentials:

• The application password that allows you to log in to your new Bitnami application.
• The server credentials that allow you to log in to your AWS Cloud server using an SSH client and execute commands on the server using the command line. These credentials consist of an SSH username and key.

What SSH username should I use for secure shell access to my application?

SSH username: bitnami

How to start or stop the services?

Each Bitnami stack includes a control script that lets you easily stop, start and restart services. The script is located at /opt/bitnami/ctlscript.sh. Call it without any service name arguments to start all services:

$ sudo /opt/bitnami/ctlscript.sh start

Or use it to restart a single service, such as Apache only, by passing the service name as argument:

$ sudo /opt/bitnami/ctlscript.sh restart apache

Use this script to stop all services:

$ sudo /opt/bitnami/ctlscript.sh stop

Restart the services by running the script without any arguments:

$ sudo /opt/bitnami/ctlscript.sh restart

Obtain a list of available services and operations by running the script without any arguments:

$ sudo /opt/bitnami/ctlscript.sh

What are the default ports?

A port is an endpoint of communication in an operating system that identifies a specific process or a type of service. Bitnami stacks include several services or servers that require a port.

IMPORTANT: Making this application's network ports public is a significant security risk. You are strongly advised to only allow access to those ports from trusted networks. If, for development purposes, you need to access from outside of a trusted network, please do not allow access to those ports via a public IP address. Instead, use a secure channel such as a VPN or an SSH tunnel. Follow these instructions to remotely connect safely and reliably.

Port 22 is the default port for SSH connections.

Bitnami opens some ports for the main servers. These are the ports opened by default: 80, 443.

Which components are installed with the Bitnami Nginx Stack?

The Bitnami Nginx Stack ships the components listed below. If you want to know which specific version of each component is bundled in the stack you are downloading, check the README.txt file on the download page or in the stack installation directory. You can also find more information about each component using the links below.

How can I get started with Nginx?

Once the deployment finishes, you can access the welcome page from your browser: http://SERVER-IP/.

To get started, we suggest the following steps:

Step 1: Deploy a custom PHP application

The main directory to deploy your PHP application is /opt/bitnami/nginx/html/. You can copy your PHP application files to that directory and access the application via your browser. If you do not have a PHP application yet, we suggest deploying the PHP info example.

Do you have issues trying to connect to your server? Check our FAQ.

Step 2: Create a virtual host for your application

Nginx lets you configure virtual hosts for your applications, such that you can access them at (for example) http://APPNAME.example.com instead of http://example.com/APPNAME.

For information on how to do this, refer to these instructions.

Step 3: Access phpMyAdmin

phpMyAdmin is a PHP-based application intended to handle the administration of MySQL over the Web. For security reasons, this application is not accessible via web by default. To access it from a remote system, we recommend creating a SSH tunnel that routes requests to the Apache Web server from 127.0.0.1.

Find more information on how to access phpMyAdmin.

How to upload files to the server with SFTP?

The first step is to ensure that you have an SSH key for your server.

If you are using the Bitnami Launchpad for AWS Cloud, download the SSH key for your server in .ppk format (for FileZilla or WinSCP) or in .pem format (for Cyberduck) from the Launchpad detail page for your server.

Although you can use any SFTP/SCP client to transfer files to your server, this guide documents FileZilla (Windows, Linux and Mac OS X), WinSCP (Windows) and Cyberduck (Mac OS X).

Using an SSH Key

Once you have your server's SSH key, choose your preferred application and follow the steps below to connect to the server using SFTP.

FileZilla

Follow these steps:

• Download and install FileZilla.
• Launch FileZilla and use the "Edit -> Settings" command to bring up FileZilla's configuration settings.

• Within the "Connection -> SFTP" section, use the "Add keyfile" command to select the private key file for the server. FileZilla will use this private key to log in to the server.

  

• Use the "File -> Site Manager -> New Site" command to bring up the FileZilla Site Manager, where you can set up a connection to your server.
• Enter your server host name and specify bitnami as the user name.

• Select "SFTP" as the protocol and "Ask for password" as the logon type.

  

• Use the "Connect" button to connect to the server and begin an SFTP session. You might need to accept the server key, by clicking "Yes" or "OK" to proceed.

You should now be logged into the /home/bitnami directory on the server. You can now transfer files by dragging and dropping them from the local server window to the remote server window.

If you have problems accessing your server, get extra information by use the "Edit -> Settings -> Debug" menu to activate FileZilla's debug log.

WinSCP

Follow these steps:

• Download and install WinSCP.
• Launch WinSCP and in the "Session" panel, select "SCP" as the file protocol.

• Enter your server host name and specify bitnami as the user name.

  

• Click the "Advanced…" button and within the "SSH -> Authentication -> Authentication parameters" section, select the private key file for the server. WinSCP will use this private key to log in to the server.

  

• From the "Session" panel, use the "Login" button to connect to the server and begin an SCP session.

You should now be logged into the /home/bitnami directory on the server. You can now transfer files by dragging and dropping them from the local server window to the remote server window.

If you need to upload files to a location where the bitnami user doesn't have write permissions, you have two options:

• Once you have configured WinSCP as described above, click the "Advanced…" button and within the "Environment -> Shell" panel, select sudo su - as your shell. This will allow you to upload files using the administrator account.

  

• Upload the files to the /home/bitnami directory as usual. Then, connect via SSH and move the files to the desired location with the sudo command, as shown below:

   $ sudo mv /home/bitnami/uploaded-file /path/to/desired/location/
  

Cyberduck

Follow these steps:

• Select the "Open Connection" command and specify "SFTP" as the connection protocol.

  

• In the connection details panel, under the "More Options" section, enable the "Use Public Key Authentication" option and specify the path to the private key file for the server.

  

• Use the "Connect" button to connect to the server and begin an SFTP session.

You should now be logged into the /home/bitnami directory on the server. You can now transfer files by dragging and dropping them from the local server window to the remote server window.

How to find the MySQL database credentials?

• Database username: root.
• Database password: The same as the application password. Find out how to obtain application credentials.

How to connect to the MySQL database?

You can connect to the MySQL database from the same computer where it is installed with the mysql client tool.

$ mysql -u root -p

You will be prompted to enter the root user password. This is the same as the application password.

How to connect to Nginx from a different machine?

For security reasons, the Nginx ports in this solution cannot be accessed over a public IP address. To connect to Nginx from a different machine, you must open port 80, 443 for remote access. Refer to the FAQ for more information on this.

IMPORTANT: Making this application's network ports public is a significant security risk. You are strongly advised to only allow access to those ports from trusted networks. If, for development purposes, you need to access from outside of a trusted network, please do not allow access to those ports via a public IP address. Instead, use a secure channel such as a VPN or an SSH tunnel. Follow these instructions to remotely connect safely and reliably.

How to access phpMyAdmin?

For security reasons, phpMyAdmin is accessible only when using 127.0.0.1 as the hostname. To access it from a remote system, you must create an SSH tunnel that routes requests to the Web server from 127.0.0.1. This implies that you must be able to connect to your server over SSH in order to access these applications remotely.

Accessing phpMyAdmin on Windows

Watch the following video to learn how to easily access phpMyAdmin on Windows through an SSH tunnel:

In order to access phpMyAdmin via SSH tunnel you need an SSH client. In the instructions below we have selected PuTTY, a free SSH client for Windows and UNIX platforms. The first step is having PuTTY configured. Please, check how to configure it in the section how to connect to the server through SSH using an SSH client on Windows.

Once you have your SSH client correctly configured and you tested that you can successfully access to your instance via SSH, you need to create an SSH tunnel in order to access phpMyAdmin. For doing so, follow these steps:

• In the "Connection -> SSH -> Tunnels" section, add a new forwarded port by introducing the following values:

  • Source port: 8888
  • Destination: localhost:80

  This will create a secure tunnel by forwarding a port (the "destination port") on the remote server to a port (the "source port") on the local host (127.0.0.1 or localhost).

• Click the "Add" button to add the secure tunnel configuration to the session. (You'll see the added port in the list of "Forwarded ports").

  

• In the "Session" section, save your changes by clicking the "Save" button.
• Click the "Open" button to open an SSH session to the server. The SSH session will now include a secure SSH tunnel between the two specified ports.
• Access the phpMyAdmin console through the secure SSH tunnel you created, by browsing to http://127.0.0.1:8888/phpmyadmin.

• Log in to phpMyAdmin by using the following credentials:

  • Username: root
  • Password: application password. (Refer to our FAQ to learn how to find your application credentials).

Here is an example of what you should see:

If you are unable to access phpMyAdmin, verify that the SSH tunnel was created by checking the PuTTY event log (accessible via the "Event Log" menu):

Accessing phpMyAdmin on Linux and Mac OS X

To access the application using your Web browser, create an SSH tunnel, as described below.

• Open a new terminal window on your local system (for example, using "Finder -> Applications -> Utilities -> Terminal" in Mac OS X or the Dash in Ubuntu).
• Make sure that you have your SSH credentials (.pem key file) in hand.

• Run the following command to configure the SSH tunnel. Remember to replace KEYFILE with the path to your private key and SERVER-IP with the public IP address or hostname of your server:

     $ ssh -N -L 8888:127.0.0.1:80 -i KEYFILE bitnami@SERVER-IP
  

• Access the phpMyAdmin console through the secure SSH tunnel you created, by browsing to http://127.0.0.1:8888/phpmyadmin.

• Log in to phpMyAdmin by using the following credentials:

  • Username: root
  • Password: application password. (Refer to our FAQ to learn how to find your application credentials).

Here is an example of what you should see:

How to reset the MariaDB root password?

If you don't remember your MariaDB root password, you can follow the steps below to reset it to a new value:

• Create a file in /home/bitnami/mysql-init with the content shown below (replace NEW_PASSWORD with the password you wish to use):

   UPDATE mysql.user SET Password=PASSWORD('NEW_PASSWORD') WHERE User='root';
   FLUSH PRIVILEGES;
  

• Stop the MariaDB server:

   $ sudo /opt/bitnami/ctlscript.sh stop mariadb
  

• Start MariaDB with the following command:

   $ sudo /opt/bitnami/mariadb/bin/mysqld_safe --defaults-file=/opt/bitnami/mariadb/my.cnf --pid-file=/opt/bitnami/mariadb/data/mysqld.pid --init-file=/home/bitnami/mysql-init 2> /dev/null &
  

• Restart the MariaDB server:

   $ sudo /opt/bitnami/ctlscript.sh restart mariadb
  

• Remove the init script

   $ rm /home/bitnami/mysql-init
  

How to change the MariaDB root password?

You can modify the MariaDB password using the following command at the shell prompt:

$ /opt/bitnami/mariadb/bin/mysqladmin -p -u root password NEW_PASSWORD

How to create an SSL certificate?

You can create your own SSL certificate with the OpenSSL binary. A certificate request can then be sent to a certificate authority (CA) to get it signed into a certificate, or if you have your own certificate authority, you may sign it yourself, or you can use a self-signed certificate (because you just want a test certificate or because you are setting up your own CA).

• Generate a new private key:

   $ sudo openssl genrsa -out /opt/bitnami/apps/APPNAME/conf/certs/server.key 2048
  

• Create a certificate:

   $ sudo openssl req -new -key /opt/bitnami/apps/APPNAME/conf/certs/server.key -out /opt/bitnami/apps/APPNAME/conf/certs/cert.csr
  

  IMPORTANT: Enter the server domain name when the above command asks for the "Common Name".

• Send cert.csr to the certificate authority. When the certificate authority completes their checks (and probably received payment from you), they will hand over your new certificate to you.

• Until the certificate is received, create a temporary self-signed certificate:

   $ sudo openssl x509 -in /opt/bitnami/apps/APPNAME/conf/certs/cert.csr -out /opt/bitnami/apps/APPNAME/conf/certs/server.crt -req -signkey /opt/bitnami/apps/APPNAME/conf/certs/server.key -days 365
  

• Back up your private key in a safe location after generating a password-protected version as follows:

   $ sudo openssl rsa -des3 -in /opt/bitnami/apps/APPNAME/conf/certs/server.key -out privkey.pem
  

  Note that if you use this encrypted key in the configuration file, Nginx won't be able to start. Regenerate the key without password protection from this file as follows:

   $ sudo openssl rsa -in privkey.pem -out /opt/bitnami/apps/APPNAME/conf/certs/server.key
  

Find more information about certificates at http://www.openssl.org.

How to enable HTTPS support with SSL certificates?

Bitnami images come with SSL support already pre-configured and with a dummy certificate in place. Although this dummy certificate is fine for testing and development purposes, you will usually want to use a valid SSL certificate for production use. You can either generate this on your own (explained here) or you can purchase one from a commercial certificate authority.

Once you obtain the certificate and certificate key files, you will need to update your server to use them. Follow these steps to activate SSL support:

• Use the table below to identify the correct locations for your certificate and configuration files.

  Variable	Value
  Current application URL	https://[custom-domain]/
  	Example: https://my-domain.com/ or https://my-domain.com/appname
  Nginx configuration file	/opt/bitnami/nginx/conf/bitnami/bitnami.conf
  Certificate file	/opt/bitnami/nginx/conf/server.crt
  Certificate key file	/opt/bitnami/nginx/conf/server.key

• Copy your SSL certificate and certificate key file to the specified locations.

• Once you have copied all the server certificate files, you may make them readable by the root user only with the following commands:

   $ sudo chown root:root /opt/bitnami/nginx/conf/server*
  
   $ sudo chmod 600 /opt/bitnami/nginx/conf/server*
  

• Open port 443 in the server firewall. Refer to the FAQ for more information.

• Restart the Nginx server.

   $ sudo /opt/bitnami/ctlscript.sh restart nginx
  

You should now be able to access your application using an HTTPS URL.

How to install a Let's Encrypt certificate in your Web server?

To learn more about this topic, read our guide on generating and installing Let's Encrypt certificates for Bitnami applications.

How to create a Virtual Host in the Bitnami Nginx Stack?

Nginx lets you configure virtual hosts for your applications, such that you can access them at (for example) http://APPNAME.example.com instead of http://example.com/APPNAME.

• Edit the /opt/bitnami/nginx/conf/bitnami/bitnami-apps-prefix.conf file and comment out the line below so that it looks like this:

  #include "/opt/bitnami/apps/APPNAME/conf/nginx-prefix.conf";
  

• Include the virtual host configuration file for your application in the /opt/bitnami/nginx/conf/bitnami/bitnami-apps-vhosts.conf file:

   include "/opt/bitnami/apps/APPNAME/conf/nginx-vhosts.conf";
  

• Update the application's nginx-app.conf file at /opt/bitnami/apps/APPNAME/conf/nginx-app.conf with the revised application URL if necessary. For example, you might replace the line

   rewrite ^/wordpress/(.+)$ /wordpress/index.php?q=$1 last;
  

  with

   rewrite ^/(.+)$ /index.php?q=$1 last;
  

• Update the application configuration to reflect the revised URL if necessary. This is an application-specific step and different applications will require different changes. For example, if you are using WordPress, you would need to edit the /opt/bitnami/apps/wordpress/htdocs/wp-config.php file and add the following lines:

   define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/');
   define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] . '/');
  

• Restart the Nginx server:

   $ sudo /opt/bitnami/ctlscript.sh restart nginx
  

How to increase the upload size limit in the Bitnami Nginx Stack?

Add the client_max_body_size directive inside the http { } section of the /opt/bitnami/nginx/conf/nginx.conf file. For instance, to increase your upload size to 20MB, add the following line:

client_max_body_size 20m;

Remember to restart the Nginx server for your changes to take effect.

$ sudo /opt/bitnami/ctlscript.sh restart nginx

To increase the upload file size limit for PHP, follow the steps described here.

How to create a password to protect access to an application?

To configure Nginx to request a username and password when accessing your application, follow these steps:

• At the console, type the following commands. Remember to replace APPNAME, USERNAME and PASSWORD with your application name, desired username and desired password respectively.

    $ sudo apt-get update
    $ sudo apt-get install apache2-utils
    $ cd /opt/bitnami/APPNAME/conf/
    $ sudo htpasswd -cb users USERNAME PASSWORD
  

• Edit the /opt/bitnami/apps/APPNAME/conf/nginx-app.conf file and update the default location block as shown below:

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_read_timeout 300;
        fastcgi_pass unix:/opt/bitnami/php/var/run/www.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        include fastcgi_params;
        auth_basic "Restricted Area";
        auth_basic_user_file /opt/bitnami/APPNAME/conf/users;
    }
  

  NOTE: If you don't wish to protect the entire application, but only a sub-URL, create a new location block as shown above only for the sub-URL you wish to protect.

• Restart the Nginx server:

   $ sudo /opt/bitnami/ctlscript.sh restart nginx
  

When accessing the application, you will see an authentication popup window. Enter the username and password defined in the first step:

To change the password later, run the htpasswd utility without the -c switch:

$ sudo htpasswd /opt/bitnami/users USERNAME

How to force HTTPS redirection with Nginx?

Modify the /opt/bitnami/nginx/conf/bitnami/bitnami.conf file so that it looks like this:

server {
      listen 80;
      server_name localhost;
      return 301 https://$host$request_uri;
      include "/opt/bitnami/nginx/conf/bitnami/bitnami-apps-prefix.conf";
  }

After modifying the Nginx configuration file:

• Open port 443 in the server firewall. Refer to the FAQ for more information.

• Restart Nginx to apply the changes.

How can I run a command in the Bitnami Nginx Stack?

Log in to the server console as the bitnami user and run the command as usual. The required environment is automatically loaded for the bitnami user.

Which components are installed with the Bitnami Nginx Stack?

The Bitnami Nginx Stack ships the components listed below. If you want to know which specific version of each component is bundled in the stack you are downloading, check the README.txt file on the download page or in the stack installation directory. You can also find more information about each component using the links below.

• Copy the phpinfo.php script from the installation directory to a publicly accessible location under the Web server document root.

   $ cd /opt/bitnami
   $ cp docs/phpinfo.php nginx/html
  

• Browse to http://SERVER-IP/phpinfo.php.

How to create a custom PHP application?

Many users run a Bitnami stack as a development environment for their own PHP projects (as opposed to running third-party applications such as Joomla! or WordPress). To deploy your PHP application in this environment, you have two options:

• To make a single PHP application accessible at the root URL of the Web server (for example, http://localhost), simply copy the PHP files into the /opt/bitnami/nginx/html folder. For an example, take a look at the phpinfo example.

• To have several applications running, create the same structure used by Bitnami when installing Bitnami PHP applications. Recent versions of Bitnami stacks ship a demo application with this structure to help you get started. To use this, follow the steps below:

  • Copy the /opt/bitnami/docs/demo folder into the /opt/bitnami/apps directory.

    $ sudo cp -r /opt/bitnami/docs/demo /opt/bitnami/apps
    

  • Add the following line to the end of the /opt/bitnami/nginx/conf/bitnami/bitnami-apps-prefix.conf file:

    include "/opt/bitnami/apps/demo/conf/nginx-prefix.conf";
    

  • Restart the Nginx server using the command-line tool.

    $ sudo /opt/bitnami/ctlscript.sh restart nginx
    

  You should now be able to access the demo application at http://SERVER-IP/demo. You should see a "Hello world" message in your browser.

• If your stack does not include a demo application, or if you prefer to create a custom PHP application from scratch, follow the steps below. These steps assume that your application will live in the /opt/bitnami/apps/myapp/ directory:

  • Run the following commands to create the directories:

    $ sudo mkdir /opt/bitnami/apps/myapp
    $ sudo mkdir /opt/bitnami/apps/myapp/htdocs/
    $ sudo mkdir /opt/bitnami/apps/myapp/conf
    

  • Create and edit the /opt/bitnami/apps/myapp/conf/nginx-prefix.conf file and add the line below to it:

    location /myapp {
    alias "/opt/bitnami/apps/myapp/htdocs/";
    include "/opt/bitnami/apps/myapp/conf/nginx-app.conf";
    }
    

  • Create and edit the /opt/bitnami/apps/myapp/conf/nginx-app.conf file and add the content below to it. This is the main configuration file for your application, so modify it further depending on your application's requirements.

    index index.php index.html index.htm;
    location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_read_timeout 300;
    fastcgi_pass unix:/opt/bitnami/php/var/run/www.sock;
    fastcgi_index index.php;
    fastcgi_param  SCRIPT_FILENAME $request_filename;
    include fastcgi_params;
    }
    

  • Add the following line to the end of the /opt/bitnami/nginx/conf/bitnami/bitnami-apps-prefix.conf file:

    include "/opt/bitnami/apps/myapp/conf/nginx-prefix.conf";
    

  • Restart the Nginx server:

    $ sudo /opt/bitnami/ctlscript.sh restart nginx
    

  • Access the application at http://SERVER-IP/myapp.

• If you want to use a virtual host for an application located at /opt/bitnami/apps/myapp, edit the /opt/bitnami/apps/myapp/conf/nginx-vhosts.conf and add the content below to it:

  server {
      listen    80;
      root "/opt/bitnami/apps/myapp/htdocs/";
      server_name  myapp.example.com www.myapp.example.com;
      include "/opt/bitnami/apps/myapp/conf/nginx-app.conf";
  }
  server {
      listen    443 ssl;
      root   "/opt/bitnami/apps/myapp/htdocs/";
      server_name  myapp.example.com www.myapp.example.com;
      ssl_certificate  "/opt/bitnami/apps/myapp/conf/certs/server.crt";
      ssl_certificate_key  "/opt/bitnami/apps/myapp/conf/certs/server.key";
      ssl_session_cache    shared:SSL:1m;
      ssl_session_timeout  5m;
      ssl_ciphers  HIGH:!aNULL:!MD5;
      ssl_prefer_server_ciphers  on;
      include "/opt/bitnami/apps/myapp/conf/nginx-app.conf";
  }
  

  • Add the following line to the end of the /opt/bitnami/nginx/conf/bitnami/bitnami-apps-vhosts.conf file:

    include "/opt/bitnami/apps/myapp/conf/nginx-vhosts.conf";
    

  • Restart the Nginx server:

    $ sudo /opt/bitnami/ctlscript.sh restart nginx
    

  • Access the application at http://myapp.example.com.

How can I deploy my PHP application?

The main directory to deploy your PHP application is /opt/bitnami/apache2/htdocs. You can copy your PHP application files to that directory and access the application via your browser at http://SERVER-IP/.

How to create a full backup of Nginx?

Backup

The Bitnami Nginx Stack is self-contained and the simplest option for performing a backup is to copy or compress the Bitnami stack installation directory. To do so in a safe manner, you will need to stop all servers, so this method may not be appropriate if you have people accessing the application continuously.

Follow these steps:

• Change to the directory in which you wish to save your backup:

    $ cd /your/directory
  

• Stop all servers:

    $ sudo /opt/bitnami/ctlscript.sh stop
  

• Create a compressed file with the stack contents:

    $ sudo tar -pczvf application-backup.tar.gz /opt/bitnami
  

• Restart all servers:

    $ sudo /opt/bitnami/ctlscript.sh start
  

You should now download or transfer the application-backup.tar.gz file to a safe location.

Restore

Follow these steps:

• Change to the directory containing your backup:

    $ cd /your/directory
  

• Stop all servers:

    $ sudo /opt/bitnami/ctlscript.sh stop
  

• Move the current stack to a different location:

    $ sudo mv /opt/bitnami /tmp/bitnami-backup
  

• Uncompress the backup file to the original directoryv

    $ sudo tar -pxzvf application-backup.tar.gz -C /
  

• Start all servers:

    $ sudo /opt/bitnami/ctlscript.sh start
  

If you want to create only a database backup, refer to these instructions for MySQL and PostgreSQL.

How to debug errors in your database?

The main log file is created at /opt/bitnami/mysql/data/mysqld.log on the MySQL database server host.
