ISPConfig 3 has a builtin feature to support multiple PHP versions on one server and select the optimal PHP version for a website. This feature works with PHP-FPM and FastCGI. This tutorial shows how to build PHP 5.6 as a PHP-FPM and a FastCGI version on a Debian Wheezy server. These PHP 5.5 builds include Zend OPcache, and APCu.
1 Preliminary Note
I will install PHP 5.6.36, the latest PHP 5 version at the time of this writing. I will also show how to build some additional PHP extensions such as APCu and memcache. The ioncube loader is not available for php 5.6 at this time, so I will leave out that step.
Please note that PHP-FPM can be used on both Apache and nginx servers, while FastCGI is available only for Apache servers.
PHP-FPM and FastCGI are mutually exclusive in PHP 5.6, that's why I show two ways of building PHP, one for PHP-FPM, one for FastCGI, however you can compile PHP twice to get both, one time with --enable-fpm and one time with --enable-cgi (make sure to use different base directories, such as /opt/php-5.6.36 for PHP-FPM and /opt/phpfcgi-5.6.36 for FastCGI).
2 Building PHP 5.6.36 (PHP-FPM)
Download and extract PHP 5.6.36:
mkdir /opt/php-5.6.36
mkdir /usr/local/src/php5-build
cd /usr/local/src/php5-build
wget http://de2.php.net/get/php-5.6.36.tar.bz2/from/this/mirror -O php-5.6.36.tar.bz2
tar jxf php-5.6.36.tar.bz2
cd php-5.6.36/
Install the prerequisites for building PHP5:
apt-get install build-essential
apt-get build-dep php5
apt-get install libfcgi-dev libfcgi0ldbl libjpeg62-dbg libmcrypt-dev libssl-dev libc-client2007e libc-client2007e-dev
ln -s /usr/lib/libc-client.a /usr/lib/x86_64-linux-gnu/libc-client.a
(The last command is needed if you build PHP with --with-imap, because otherwise ./configure will stop with the following error:
checking for crypt in -lcrypt... yes
configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.
[email protected]:/usr/local/src/php5-build/php-5.6.36#
)
Configure and build PHP 5.6.36 as follows (you can adjust the ./configure command to your needs, take a look at
./configure --help
to see all available options; if you use a different ./configure command, it is possible that additional libraries are required, or the build process will fail):
./configure --prefix=/opt/php-5.6.36 --with-pdo-pgsql --with-zlib-dir --with-freetype-dir --enable-mbstring --with-libxml-dir=/usr --enable-soap --enable-calendar --with-curl --with-mcrypt --with-zlib --with-gd --with-pgsql --disable-rpath --enable-inline-optimization --with-bz2 --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --enable-exif --enable-bcmath --with-mhash --enable-zip --with-pcre-regex --with-mysql --with-pdo-mysql --with-mysqli --with-jpeg-dir=/usr --with-png-dir=/usr --enable-gd-native-ttf --with-openssl --with-fpm-user=www-data --with-fpm-group=www-data --with-libdir=/lib/x86_64-linux-gnu --enable-ftp --with-imap --with-imap-ssl --with-kerberos --with-gettext --with-xmlrpc --with-xsl --enable-opcache --enable-fpm
The last switch (--enable-fpm) makes sure this PHP version will work with PHP-FPM.
make
make install
Copy php.ini and php-fpm.conf to the correct locations:
cp /usr/local/src/php5-build/php-5.6.36/php.ini-production /opt/php-5.6.36/lib/php.ini
cp /opt/php-5.6.36/etc/php-fpm.conf.default /opt/php-5.6.36/etc/php-fpm.conf
Open /opt/php-5.6.36/etc/php-fpm.conf and adjust the following settings - in the listen line you must use an unused port (e.g. 8999; port 9000 might be in use by Debian's default PHP-FPM already), and you must add the line include=/opt/php-5.6.36/etc/pool.d/*.conf at the end:
vi /opt/php-5.6.36/etc/php-fpm.conf
[...] pid = run/php-fpm.pid [...] user = www-data group = www-data [...] listen = 127.0.0.1:8999 [...] include=/opt/php-5.6.36/etc/pool.d/*.conf
Create the pool directory for PHP-FPM:
mkdir /opt/php-5.6.36/etc/pool.d
Next create an init script for PHP-FPM:
vi /etc/init.d/php-5.6.36-fpm
#! /bin/sh

exit 1

esac
Make the init script executable and create the system startup links:
chmod 755 /etc/init.d/php-5.6.36-fpm
insserv php-5.6.36-fpm
Finally start PHP-FPM:
/etc/init.d/php-5.6.36-fpm start
As long as there are no pools in /opt/php-5.6.36/etc/pool.d, you will get this warning which you can ignore:
[email protected]:/usr/local/src/php5-build/php-5.6.36# /etc/init.d/php-5.6.36-fpm start
Starting php-fpm [29-Aug-2014 13:21:12] WARNING: Nothing matches the include pattern '/opt/php-5.6.36/etc/pool.d/*.conf' from /opt/php-5.6.36/etc/php-fpm.conf at line 528.

To enable the Zend OPcache, open /opt/php-5.6.36/lib/php.ini...
vi /opt/php-5.6.36/lib/php.ini
... and add the following line at the end:
[...] zend_extension=opcache.so
That's it - if you like, you can now install some additional modules like APCu, memcache, memcached, and ioncube.
The APCu, memcache, and memcached modules can be installed through PEAR which we must install and initialize first:
apt-get -y install php-pear
cd /opt/php-5.6.36/etc
pecl -C ./pear.conf update-channels
APCu can now be installed as follows:
pecl -C ./pear.conf install channel://pecl.php.net/apcu-4.0.6
Accept all default values. Afterwards, open /opt/php-5.6.36/lib/php.ini...
vi /opt/php-5.6.36/lib/php.ini
... and add the line extension=apcu.so at the end of the file (you can also configure some additional APCu settings):
[...] extension=apcu.so apc.enabled=1 apc.shm_size=128M apc.ttl=0 apc.gc_ttl=600 apc.enable_cli=1 apc.mmap_file_mask=/tmp/apc.XXXXXX ;apc.mmap_file_mask=/dev/zero ;apc.shm_segments = 5
The memcache extension can be installed as follows:
pecl -C ./pear.conf install memcache
Open /opt/php-5.6.36/lib/php.ini...
vi /opt/php-5.6.36/lib/php.ini
... and add the line extension=memcache.so at the end of the file:
[...] extension=memcache.so
Reload PHP-FPM afterwards:
/etc/init.d/php-5.6.36-fpm reload
In ISPConfig 3.0.5, you can configure the new PHP version under System > Additional PHP Versions. On the Name tab, you just fill in a name for the PHP version (e.g. PHP 5.6.36) - this PHP version will be listed under this name in the website settings in ISPConfig:
Go to the PHP-FPM Settings tab (the FastCGI Settings tab can be left empty) and fill out the fields as follows:
