Install different PHP modules

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:
 $ test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A: Using system packages." || echo "Approach B: Self-contained installation."
The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.

To install a PHP module, the typical process is to install the module (either via the package manager or through a manual build/install process) and then activate it in the above configuration file. Find instructions for installing specific PHP modules.

NOTE: Bitnami stacks already include a number of PHP modules, which are installed but not active. Before installing a new module, check that it is not already included. If it exists, simply enable it in the PHP configuration file.

After modifying the PHP configuration file, restart both Apache and PHP-FPM for the changes to take effect:

$ sudo /opt/bitnami/ctlscript.sh restart apache
$ sudo /opt/bitnami/ctlscript.sh restart php-fpm

APCu

APCu is the APC User Cache module. It is already included in recent Bitnami Stacks by default. If that is not the case, install it manually following the steps below:

Install the following packages:

Debian:

$ sudo apt-get update
$ sudo apt-get install build-essential libtool autoconf unzip wget

CentOS:

$ sudo yum groups mark install "Development Tools"

Download the latest source package from the web page, uncompress it and compile the module.

$ wget https://pecl.php.net/get/apcu-X.Y.Z.tgz
$ tar xzf apcu-X.Y.Z.tgz
$ cd apcu-X.Y.Z
$ phpize
$ ./configure --with-php-config=/opt/bitnami/php/bin/php-config
$ make
$ sudo make install

To enable the module, add the following line to the php.ini file:

...
extension = apcu.so
...

MSSQL

Microsoft SQL Server is a relational database management system developed by Microsoft. The steps to install the module differ for PHP5 and PHP7, and Ubuntu and Debian. Choose the appropriate section below depending on the PHP version bundled with your stack and the platform. To obtain the PHP version, use the command php -v at your console prompt.

Installation

You need to install the PHP Linux Drivers for SQL Server. The process is different for Debian and Ubuntu.

Debian

Add the microsoft packages to apt-get:

    $ sudo su
    $ curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
    $ curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list
    $ curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list
    $ exit

Install the tool with apt-get and pecl:

    $ sudo apt-get update
    $ sudo ACCEPT_EULA=Y apt-get install -y msodbcsql17 mssql-tools unixodbc-dev
    $ sudo pecl install sqlsrv
    $ sudo pecl install pdo_sqlsrv

Edit the /opt/bitnami/php/etc/php.ini file and add the lines below to it:
```
$ extension=sqlsrv.so
$ extension=pdo_sqlsrv.so
```

Ubuntu:

Add the microsoft packages to apt-get:

    $ sudo su
    $ curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
    $ curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
    $ curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
    $ exit

Install the tool with apt-get and pecl:

    $ sudo apt-get update
    $ sudo ACCEPT_EULA=Y apt-get install -y msodbcsql mssql-tools unixodbc-dev
    $ sudo pecl install sqlsrv
    $ sudo pecl install pdo_sqlsrv

Edit the /opt/bitnami/php/etc/php.ini file and add the lines below to it:
```
$ extension=sqlsrv.so
$ extension=pdo_sqlsrv.so
```

Testing

Create a file called “connect.php”:
```
 $ nano connect.php
```

Add the following PHP script, replacing the IP_ADDRESS, PORT and PASSWORD placeholders with their respective values:

 $ <?php
 $ $server = 'http://IP_ADDRESS:PORT';
 $ $dbName = 'master';
 $ $uid = 'admin';
 $ $pwd = 'PASSWORD';

 $ $conn = new PDO("sqlsrv:server=$server; database = $dbName", $uid, $pwd);
 $ $conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
 $ try {
 $   $result = $conn->query('SELECT TOP 10 * FROM [master].[INFORMATION_SCHEMA].[TABLES]');
 $   foreach ($result as $row)
 $     {
 $       print_r( $row );
 $     }
 $   } catch (Exception $e) {
 $   echo $e->getMessage();
 $   }
 $ ?>

Run the test script with the following command:
```
$ php connect.php
```

GeoIP2

Apache

The mod_geoip2 module embeds GeoIP database lookups into the Apache web server. It is only capable of looking up the IP address of a client that connects to the web server, as opposed to looking up arbitrary addresses.

If this module is not in your stack, you can install it manually following the steps below.

Install the following packages if necessary:

Debian:

$ sudo apt-get update
$ sudo apt-get install build-essential libtool autoconf unzip wget

CentOS:

$ sudo yum groups mark install "Development Tools"

Install the development files for libgeoip:

Debian:
```
$ sudo apt-get install libgeoip-dev
```
CentOS:
```
$ sudo yum install GeoIP
```

Download the latest source code from the web page, uncompress it and compile the module.
```
$ wget http://www.maxmind.com/download/geoip/api/mod_geoip2/mod_geoip2-latest.tar.gz
```
Uncompress it and build the libraries
```
$ tar xzf mod_geoip2-latest.tar.gz
$ cd mod_geoip2_*
$ sudo apxs -i -a -lGeoIP -c mod_geoip.c
```
The module should now be available at /opt/bitnami/apache2/modules/mod_geoip.so. It is also automatically included in your Apache configuration.
Enable GeoIP in the Apache configuration by adding the line GeoIPEnable On in the /opt/bitnami/apache2/conf/httpd.conf file. Find other specific configuration settings at http://dev.maxmind.com/geoip/mod_geoip2#Configuration-2.

NGINX

To compile and install the GeoIP2 module for NGINX, it is necessary to first download and compile NGINX from source with the GeoIP2 module included and then copy over the compiled module to the Bitnami stack’s existing NGINX installation. Follow these steps:

Install the libmaxminddb-dev library:

$ sudo apt-get install libmaxminddb-dev

Download and uncompress the GeoIP2 module source code using the example commands below. Note that the download URL and file name will differ depending on the version you’re downloading.
```
$ wget https://github.com/leev/ngx_http_geoip2_module/archive/3.2.tar.gz
$ tar xzf 3.2.tar.gz
```
Download and uncompress the NGINX source code using the example commands below. Note that the download URL and file name will differ depending on the version you’re downloading.

NOTE: Download the source code corresponding to the NGINX version used in your Bitnami stack.
```
$ wget http://nginx.org/download/nginx-1.18.0.tar.gz
$ tar xzf nginx-1.18.0.tar.gz
```
Compile the module as a dynamic module. Replace the PATH-TO-MODULE-DIRECTORY placeholder with the path to the directory containing the GeoIP2 module source code:
```
$ cd nginx-1.18.0
$ ./configure --add-dynamic-module=PATH-TO-MODULE-DIRECTORY
$ make
```
This should create a compiled module file named objs/ngx_http_geoip2_module.so. Copy this file to the temporary directory.
```
$ cp objs/ngx_http_geoip2_module.so /tmp/
```

Change to the existing NGINX installation directory and copy the above module file to it:

$ cd /opt/bitnami/nginx
$ mkdir modules
$ cp /tmp/ngx_http_geoip2_module.so /opt/bitnami/nginx/modules/

Edit the /opt/bitnami/nginx/nginx.conf file and add the line below to it in order to load the module:
```
load_module modules/ngx_http_geoip2_module.so;
```

Imagick

The Imagick module is installed in Bitnami stacks, but is not enabled by default. To enable it, follow these steps:

Uncomment or add the following line to the /opt/bitnami/php/etc/php.ini file:
```
...
extension=imagick.so
...
```

IonCube

Follow these steps:

Download the pre-compiled version and copy the .so file to the PHP extensions directory. It is very important to install the right version of ionCube taking into account the PHP version included in your solution. For example, if you want to install ionCube on WordPress and it uses PHP 7.0.27, you need to install the version 7.0 of ionCube.

NOTE: Y and Z are placeholders. Remember to replace them with the ionCube version number that matches your PHP version.
```
$ wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
$ tar xvzf ioncube_loaders_lin_x86-64.tar.gz
$ sudo cp ioncube/ioncube_loader_lin_Y.Z.so /opt/bitnami/php/lib/php/extensions/
```

Add the following line to the php.ini file:

zend_extension = /opt/bitnami/php/lib/php/extensions/ioncube_loader_lin_Y.Z.so

MongoDB

The Mongo PHP module is a MongoDB driver. It is already included in recent Bitnami Stacks, but not enabled by default. If it is not included in your installation, execute the command below to install the module:

$ sudo pecl install mongodb
...
Build process completed successfully
Installing '/opt/bitnami/php/lib/php/extensions/mongodb.so'
install ok: channel://pecl.php.net/mongodb-1.5.3
configuration option "php_ini" is not set to php.ini location
You should add "extension=mongodb.so" to php.ini

To enable the MongoDB module, follow these steps:

Enable the module in the php.ini file:
```
...
extension=mongodb.so
...
```
Check if the extension is loaded by executing the following command:
