HHVM for Bitnami Cloud Hosting

Description

HHVM is an open source virtual machine designed for executing programs written in Hack and PHP. HHVM achieves a superior performance while maintaining the development flexibility that PHP provides.

First steps with the Bitnami HHVM Stack

Welcome to your new Bitnami application running on Bitnami Cloud Hosting! 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 credentials, consisting of a username and password. These credentials allow you to log in to your new Bitnami application.

  • The server credentials, consisting of an SSH username and key. These credentials allow you to log in to your Bitnami Cloud Hosting server using an SSH client and execute commands on the server using the command line.

What is the administrator username set for me to log in to the application for the first time?

Username: user

What is the administrator password?

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

SSH username: bitnami

How do I get my SSH key or password?

You can obtain your SSH key from the Bitnami Cloud Hosting dashboard. Click here for more information.

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.

Remember that if you need to open some ports you can follow the instructions given in the FAQ to learn how to open the server ports for remote access.

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 HHVM Stack?

The Bitnami HHVM Stack is based on our LAMP stack, with the main difference that it includes HHVM configured to serve PHP files. Find out about the components included in the LAMP stack.

How can I get started with HHVM?

To get started, we suggest the following steps:

Step 1. Deploy your 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. 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. Access phpMyAdmin.

phpMyAdmin is a PHP-based application intended to handle the administration of MySQL over the Web. Find out how to access it.

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

How to upload files to the server with SFTP?

NOTE: Bitnami applications can be found in /opt/bitnami/apps.

First, obtain your SSH credentials by following these steps:

  • Browse to the Bitnami Cloud Hosting dashboard and sign in if required using your Bitnami account.

  • Select the "Servers" menu item.

  • Select your cloud server from the resulting list.

  • Click the "Manage" button.

  • On the resulting page, note the server IP address.

    SSH credentials

  • Click the "Connect" button and download the SSH key for your server in .ppk format (for FileZilla or WinSCP) or in .pem format (for Cyberduck).

    SSH credentials

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
IMPORTANT: To use FileZilla, your server private key should be in PPK format.

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.

    FileZilla configuration

  • 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.

    FileZilla configuration

  • 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
IMPORTANT: To use WinSCP, your server private key should be in PPK format.

Follow these steps:

  • Download and install WinSCP.
  • Launch WinSCP and in the "Session" panel, select "SFTP" as the file protocol.
  • Enter your server host name and specify bitnami as the user name.

    WinSCP configuration

  • 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.

    WinSCP configuration

  • 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.

    WinSCP configuration

  • 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
IMPORTANT: To use Cyberduck, your server private key should be in PEM format.

Follow these steps:

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

    Cyberduck configuration

  • 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.

    Cyberduck configuration

  • 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 check the installed PHP modules?

The easiest way to check which PHP modules are installed is to create a test script using the phpinfo() function. Open your favorite text editor and type:

<?php phpinfo(); ?>

Save the file as phptest.php in /opt/bitnami/apache2/htdocs/. Make sure Apache is up and running, open a browser and type http://SERVER-IP/phptest.php. You should then see a screen showing detailed information about the PHP version you are using and installed modules.

You can also run the following command:

$ /opt/bitnami/php/bin/php -m

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 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/apache2/htdocs 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/apache2/conf/bitnami/bitnami-apps-prefix.conf file:

      Include "/opt/bitnami/apps/demo/conf/httpd-prefix.conf"
      
    • Restart the Apache server using the command-line tool.

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

    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/httpd-prefix.conf file and add the line below to it:

      Alias /myapp/ "/opt/bitnami/apps/myapp/htdocs/"
      Alias /myapp "/opt/bitnami/apps/myapp/htdocs/"
      Include "/opt/bitnami/apps/myapp/conf/httpd-app.conf"
      
    • Create and edit the /opt/bitnami/apps/myapp/conf/httpd-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.

      <Directory /opt/bitnami/apps/myapp/htdocs/>
          Options +FollowSymLinks
          AllowOverride None
          <IfVersion < 2.3 >
          Order allow,deny
          Allow from all
          </IfVersion>
          <IfVersion >= 2.3>
          Require all granted
          </IfVersion>
      </Directory>
      
      NOTE: If your application uses .htaccess files, you should change the AllowOverride None option to AllowOverride All. Find out how to move the .htaccess file content to the main server configuration file.
    • Once you have created the files and directories above, add the following line to the end of the main Apache configuration file at /opt/bitnami/apache2/conf/bitnami/bitnami-apps-prefix.conf, as shown below:

      Include "/opt/bitnami/apps/myapp/conf/httpd-prefix.conf"
      
    • Restart the Apache server:

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

      You should now be able to access the application at http://SERVER-IP/myapp.

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.

IMPORTANT: Before following the steps below, ensure that your Web and database servers are running.
NOTE: The steps below suggest using port 8888 for the SSH tunnel. If this port is already in use by another application on your local machine, replace it with any other port number greater than 1024 and modify the steps below accordingly. Similarly, if you have enabled Varnish, your stack's Web server might be running on port 81. In this case, modify the steps below to use port 81 instead of port 80 for the tunnel endpoint.

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").

    PuTTY configuration

  • 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:

Access phpMyAdmin

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):

PuTTY configuration

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
    
NOTE: If successful, the above command will create an SSH tunnel but will not display any output on the server console.
  • 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).
