Install different PHP modules

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

NOTE: The APCu module is only compatible with PHP 7.x.

APCu is the APC User Cache module. 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

Enable the module by adding the following line in the php.ini file:
```
...
extension = apcu.so
...
```

eAccelerator

eAccelerator is a free open-source PHP accelerator and optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution.

Follow the steps below to install this module:

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 code from the eAccelerator web page, copy to the server, uncompress it and compile the module:

$ unzip eaccelerator-*.zip
$ export PHP_AUTOCONF=/usr/bin/autoconf
$ export PHP_PREFIX=/opt/bitnami/php
$ cd eaccelerator-0.9.6.1
$ /opt/bitnami/php/bin/phpize
$ ./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
$ make
$ sudo make install

Enable the module in the php.ini file:
```
...
extension=eaccelerator.so
...
```

Check it and verify that the output looks similar:

$ php -version

Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
    with eAccelerator v0.9.5-beta2, Copyright (c) 2004-2006 eAccelerator, by eAccelerator

Now, configure this module in the php.ini file. For more information, refer to http://eaccelerator.net/wiki/InstallFromSource.

FreeTDS and MSSQL

FreeTDS is a set of libraries for Unix and Linux that allow your programs to natively talk to Microsoft SQL Server and Sybase databases.

NOTE: Since LAMP stack v5.4.25, this module is already included so it is only necessary to enable the module in the php.ini file.

Follow these steps:

Load the build environment and add -liconv to the LDFLAGS:

$ .  /opt/bitnami/scripts/build-setenv.sh
$ export LDFLAGS="$LDFLAGS -liconv"

Install FreeTDS:

$ wget ftp://ftp.freetds.org/pub/freetds/stable/freetds-patched.tar.gz
$ tar zxf freetds-patched.tgz
$ cd freetds-0.95.21/
$ ./configure --enable-msdblib --prefix=/usr/local/freetds
$ make
$ sudo make install
$ cd ..

Compile and install the MSSQL module for PHP. Note that you should download the module that matches the PHP version in use. Check the current PHP version with the php -v command.

$ wget http://us.php.net/distributions/php-5.4.45.tar.bz2
$ tar jxf php-5.4.45.tar.bz2
$ cd php-5.4.45/ext/mssql/
$ phpize
$ ./configure --with-mssql=/usr/local/freetds
$ make
$ sudo make install

Confirm that the mssql.so library has been copied to the /opt/bitnami/php/lib/php/extensions/ directory.
Edit the /opt/bitnami/php/etc/php.ini file and add the line below to it:
```
extension=mssql.so
```

Restart the server:

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

GeoIP2

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 -xzvf 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.

Restart the Apache server:

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

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

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

Restart PHP-FPM and Apache.

Thanks to @Chris_James for posting this guide!

Tidy

Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipulate HTML documents, but also traverse the document tree.

If this module is not in your stack, you can install it manually following these steps:

Install the following packages (they are already in the machine in recent versions):

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 code from the web page, uncompress it and compile the module:
```
$ wget http://tidy.cvs.sourceforge.net/viewvc/tidy/tidy/?view=tar
```

Uncompress it and build the libraries:

$ cd /home/bitnami
$ tar -xzvf tidy-tidy.tar.gz
$ cd tidy/build/gmake
$ make

Download the PHP source code version that you are currently using and uncompress it. Then, build the shared module for tidy:

$ tar -xzvf php-VERSION.tar.gz
$ cd php/ext/tidy
$ ./phpize
$ ./configure --with-tidy=/home/bitnami/tidy
$ make
$ sudo make install

XCache

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

Add the following lines to the /opt/bitnami/php/etc/php.ini file:
```
...
[xcache-common]
extension=xcache.so
...
```
Restart the Apache server to include the new configuration:
```
$ sudo /opt/bitnami/ctlscript.sh restart apache
```

Install the XCache administration page

Once XCache is installed, add the XCache administration page to obtain information on cache operations. This is not included by default, so follow the steps below:

Download the complete tarball containing the XCache Administration Page for the XCache version included in the Bitnami stack. Find XCache versions at http://xcache.lighttpd.net. To check your current XCache version, use the command php -v.
Extract the tarball content and use the htdocs folder to enable the XCache administration page.
Generate and save your authentication password. The XCache administration page is protected with HTTP authentication. Edit your php.ini file and add these lines to include your user and password.
```
xcache.admin.user = "user"
xcache.admin.pass = "6a4dc9133d5f3b6d9fff778aff361961"
```
The password must be specified in MD5 format. Here is a simple PHP script that returns the encrypted MD5 version of a plaintext password:
```
<?php
echo md5("password");
?>
```
Create a new xcache directory and add the Apache configuration files to it. Find out how to create a custom application.
Access your XCache administration page through your browser.

Zend Guard Loader

Zend Guard is a free runtime application that enables PHP to run scripts encoded by Zend Guard. It can be freely used by anyone looking to run encoded applications. Follow these steps:

$ sudo cp ZendGuard*/php-5.4.x/ZendGuardLoader.so /opt/bitnami/php/lib/php/extensions/

Add the following entry to the end of the php.ini file:

zend_extension = /opt/bitnami/php/lib/php/extensions/ZendGuardLoader.so

Check that the module was correctly installed with the following command:
```
$ php -m | grep Zend
```

ZipArchive

ZipArchive is a class of the zip PHP module. This module is enabled by default. Check it with the following command:

$ sudo /opt/bitnami/php/bin/php -m | grep zip
zip

Here is a script named sample.php that lists the content of a zip file named sample.zip:

<?php
$za = new ZipArchive();
$za->open('sample.zip');
for( $i = 0; $i < $za->numFiles; $i++ ){
    $stat = $za->statIndex( $i );
    print_r( basename( $stat['name'] ) . PHP_EOL );
}
?>

To use this script, create a sample.zip file and run this script at the server console, as below:

$ /opt/bitnami/php/bin/php sample.php
