Since ISPConfig 3.0.5, it is possible to use multiple PHP versions on one server and select the optimal PHP version for a website. This feature works with PHP-FPM (starting with PHP 5.3) and FastCGI (all PHP 5.x versions). This tutorial shows how to build PHP 5.3 and PHP 5.4 as a PHP-FPM and a FastCGI version on an Ubuntu 12.10 server. These PHP versions can be used together with the default PHP (installed through apt) in ISPConfig.

I do not issue any guarantee that this will work for you!


1 Preliminary Note

I will install PHP 5.3.22 and PHP 5.4.12, the latest PHP 5.3 and 5.4 versions at the time of this writing. I will also show how to build some additional PHP extensions such as APC, memcache, memcached, and ioncube.

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 5.3 and 5.4, 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-5.3.22 for PHP-FPM and /opt/phpfcgi-5.3.22 for FastCGI).


2 Building PHP 5.3.22 (PHP-FPM)

Download and extract PHP 5.3.22:

mkdir /opt/php-5.3.22
mkdir /usr/local/src/php5-build
cd /usr/local/src/php5-build
wget -O php-5.3.22.tar.bz2
tar jxf php-5.3.22.tar.bz2

cd php-5.3.22/

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.

Configure and build PHP 5.3.22 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-5.3.22 \
--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 \
--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 \

The last switch (--enable-fpm) makes sure this PHP version will work with PHP-FPM.

make install

Copy php.ini and php-fpm.conf to the correct locations:

cp /usr/local/src/php5-build/php-5.3.22/php.ini-production /opt/php-5.3.22/lib/php.ini

cp /opt/php-5.3.22/etc/php-fpm.conf.default /opt/php-5.3.22/etc/php-fpm.conf

Open /opt/php-5.3.22/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 Ubuntu's default PHP-FPM already), and you must add the line include=/opt/php-5.3.22/etc/pool.d/*.conf at the end:

vi /opt/php-5.3.22/etc/php-fpm.conf

pid = run/
user = www-data
group = www-data
listen =

Create the pool directory for PHP-FPM:

mkdir /opt/php-5.3.22/etc/pool.d

Next create an init script for PHP-FPM:

vi /etc/init.d/php-5.3.22-fpm

#! /bin/sh
# Provides:          php-5.3.22-fpm
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts php-5.3.22-fpm
# Description:       starts the PHP FastCGI Process Manager daemon
php_opts="--fpm-config $php_fpm_CONF"

wait_for_pid () {
        while test $try -lt 35 ; do
                case "$1" in
                        if [ -f "$2" ] ; then
                        if [ ! -f "$2" ] ; then
                echo -n .
                try=`expr $try + 1`
                sleep 1
case "$1" in
                echo -n "Starting php-fpm "
                $php_fpm_BIN $php_opts
                if [ "$?" != 0 ] ; then
                        echo " failed"
                        exit 1
                wait_for_pid created $php_fpm_PID
                if [ -n "$try" ] ; then
                        echo " failed"
                        exit 1
                        echo " done"
                echo -n "Gracefully shutting down php-fpm "
                if [ ! -r $php_fpm_PID ] ; then
                        echo "warning, no pid file found - php-fpm is not running ?"
                        exit 1
                kill -QUIT `cat $php_fpm_PID`
                wait_for_pid removed $php_fpm_PID
                if [ -n "$try" ] ; then
                        echo " failed. Use force-exit"
                        exit 1
                        echo " done"
                       echo " done"
                echo -n "Terminating php-fpm "
                if [ ! -r $php_fpm_PID ] ; then
                        echo "warning, no pid file found - php-fpm is not running ?"
                        exit 1
                kill -TERM `cat $php_fpm_PID`
                wait_for_pid removed $php_fpm_PID
                if [ -n "$try" ] ; then
                        echo " failed"
                        exit 1
                        echo " done"
                $0 stop
                $0 start
                echo -n "Reload service php-fpm "
                if [ ! -r $php_fpm_PID ] ; then
                        echo "warning, no pid file found - php-fpm is not running ?"
                        exit 1
                kill -USR2 `cat $php_fpm_PID`
                echo " done"
                echo "Usage: $0 {start|stop|force-quit|restart|reload}"
                exit 1

Make the init script executable and create the system startup links:

chmod 755 /etc/init.d/php-5.3.22-fpm
update-rc.d php-5.3.22-fpm defaults

Finally start PHP-FPM:

/etc/init.d/php-5.3.22-fpm start

As long as there are no pools in /opt/php-5.3.22/etc/pool.d, you will get this warning which you can ignore:

[email protected]:/usr/local/src/php5-build/php-5.3.22# /etc/init.d/php-5.3.22-fpm start
Starting php-fpm [04-Mar-2013 14:58:41] WARNING: Nothing matches the include pattern '/opt/php-5.3.22/etc/pool.d/*.conf' from /opt/php-5.3.22/etc/php-fpm.conf at line 512.
[email protected]:/usr/local/src/php5-build/php-5.3.22#

That's it - if you like, you can now install some additional modules like APC, memcache, memcached, and ioncube.

The APC, 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-5.3.22/etc

pecl -C ./pear.conf update-channels

APC can now be installed as follows:

pecl -C ./pear.conf install apc

Accept all default values. Afterwards, open /opt/php-5.3.22/lib/php.ini...

vi /opt/php-5.3.22/lib/php.ini

... and add the line at the end of the file (you can also configure some additional APC settings):

;apc.shm_segments = 5

The memcache extension can be installed as follows:

pecl -C ./pear.conf install memcache

Open /opt/php-5.3.22/lib/php.ini...

vi /opt/php-5.3.22/lib/php.ini

... and add the line at the end of the file:


The memcached extension can be installed as follows:

apt-get install libmemcached-dev

pecl -C ./pear.conf install memcached

Open /opt/php-5.3.22/lib/php.ini...

vi /opt/php-5.3.22/lib/php.ini

... and add the line at the end of the file:


The ionCube Loader can be installed as follows:

cd /tmp

Next download and unpack the correct ionCube Loader package for your architecture (x86_64 or x86).

For x86_64:

tar xfvz ioncube_loaders_lin_x86-64.tar.gz

For x86:

tar xfvz ioncube_loaders_lin_x86.tar.gz

Proceed as follows:

cp ioncube/ /opt/php-5.3.22/lib/php/extensions/no-debug-non-zts-20090626/
vi /opt/php-5.3.22/lib/php.ini

Add the line zend_extension = /opt/php-5.3.22/lib/php/extensions/no-debug-non-zts-20090626/ right at the beginning of the file (before the [PHP] line):

zend_extension = /opt/php-5.3.22/lib/php/extensions/no-debug-non-zts-20090626/

Reload PHP-FPM afterwards:

/etc/init.d/php-5.3.22-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 5.3.22) - 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:

if i do execute your configure-Command on brand new installed debian Squeeze, i got errors like this:
configure: error: xml2-config not found. Please check your libxml2 installation.
  1. configure: error: Cannot find OpenSSL's libraries
  2. configure: error: Please reinstall the BZip2 distribution
  3. configure: error: jpeglib.h not found.
  4. configure: error: freetype.h not found.
  5. configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation. (On i686 system...!!! Seems to be a bug with libc-client2007e-dev  so i only could deactivate imap!)
  6. pg-conf not found
aptitude install libxml2-dev libcurl4-openssl-dev libbz2-dev libjpeg-dev libpng12-dev libxpm-dev libfreetype6-dev libfreetype6-dev libmysqlclient-dev libpq-dev

 For this, the ./configure works for me

Remember, i start from a metal bare squeeze installation! 

From: Cédric


On Ubuntu 14.04, after the fix for "libc-client.a", you also have to do the following :

ln -s /usr/include/freetype2 /usr/include/freetype2/freetype

Otherwise ./configure will failed with a "freetype.h not found" error.

Last php 5.3 version is 5.3.29  (14 Aug 2014).

Here you can get the lastes version

From: m0du1us

I'm running Ubuntu 14.04.4 and I get a configure error with freetype.h not being found. This is mentioned in PHP Bug #64405:
Here's the fix:
referencing my duplicate #66259, pkg-config or freetype-config are flexible options.  here, they produce different results:
pkg-config --cflags --libs freetype2 -I/usr/include/freetype2 -lfreetype freetype-config --cflags --libs -I/usr/include/freetype2 -lfreetype -lz -lpng15 a quick workaround @ php config-time, changing both perl -pi -e 's|(FREETYPE2_INC_DIR)=.*|$1=\$i/include|g' ./configure perl -pi -e 's|freetype2/freetype/freetype.h|freetype2/freetype.h|g' ./configure and export CPPFLAGS="`pkg-config --cflags freetype2`" which 'fixes' missing incorrect path references in GD ext, allows config & build to complete.
