Debian 9 ships with PHP 7.0 as default PHP version. Major PHP versions are not 100% compatible with each other, so a website might require a newer or older PHP version to work. ISPConfig supports it to use multiple PHP versions on the same server, the PHP version can be selected for each website individually in the website settings. This tutorial shows how to install PHP 7.1, 7.2, and 5.6 as FPM and FCGI mode alongside PHP 7.0 on a Debian 9 server. The additional PHP versions are installed in the \/opt folder, so their installation does nit affect the default PHP version<\/p>\n

1 Preliminary Note<\/h2>\n

I will install PHP 7.1, 7.2 and 5.6. Please note that PHP-FPM can be used on both Apache and Nginx servers\u00a0while FastCGI is available only for Apache servers.<\/p>\n

2 Install the prerequisites<\/h2>\n

Install the prerequisites for building PHP and the nano editor that I will use to edit the config files:<\/p>\n

apt-get install build-essential nano<\/p>\n

apt-get install libfcgi-dev libfcgi0ldbl\u00a0libjpeg62-turbo-dev libmcrypt-dev libssl-dev libc-client2007e libc-client2007e-dev\u00a0libxml2-dev\u00a0libbz2-dev\u00a0libcurl4-openssl-dev\u00a0libjpeg-dev\u00a0libpng-dev\u00a0libfreetype6-dev\u00a0libkrb5-dev\u00a0libpq-dev libxml2-dev\u00a0libxslt1-dev<\/p>\n

ln -s \/usr\/lib\/libc-client.a \/usr\/lib\/x86_64-linux-gnu\/libc-client.a<\/p>\n

cd \/usr\/include
ln -s x86_64-linux-gnu\/curl<\/p>\n

(The last command is needed if you build PHP with –with-imap<\/span>, because otherwise .\/configure<\/span> will stop with the following error:<\/p>\n

checking for crypt in -lcrypt… yes
configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.
[email\u00a0protected]<\/a>:\/usr\/local\/src\/php5-build\/php-7.1.14#<\/p>\n

)<\/p>\n

3\u00a0Compile\u00a0PHP 7.1\u00a0as PHP-FPM and Fastcgi<\/h2>\n

Download and extract PHP archive:<\/p>\n

mkdir -p \/opt\/php-7.1
mkdir \/usr\/local\/src\/php7.1-build
cd \/usr\/local\/src\/php7.1-build
wget http:\/\/de2.php.net\/get\/php-7.1.14.tar.bz2\/from\/this\/mirror\u00a0-O php-7.1.14.tar.bz2
tar jxf php-7.1.14.tar.bz2<\/p>\n

cd\u00a0php-7.1.14\/<\/p>\n

Configure and build PHP 7.1 as follows (you can adjust the .\/configure<\/span> command to your needs, take a look at<\/p>\n

.\/configure –help<\/p>\n

to see all available options; if you use a different .\/configure<\/span> command, it is possible that additional libraries are required, or the build process will fail):<\/p>\n

.\/configure –prefix=\/opt\/php-7.1 –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-pdo-mysql –with-mysqli –with-mysql-sock=\/var\/run\/mysqld\/mysqld.sock\u00a0–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<\/p>\n

The last switch (–enable-fpm<\/span>) makes sure this PHP version will work with PHP-FPM.<\/p>\n

make
make install<\/p>\n

Copy php.ini<\/span> and php-fpm.conf<\/span> to the correct locations:<\/p>\n

cp \/usr\/local\/src\/php7.1-build\/php-7.1<\/span>\/php.ini-production \/opt\/php-7.1\/lib\/php.ini<\/p>\n

cp \/opt\/php-7.1\/etc\/php-fpm.conf.default \/opt\/php-7.1\/etc\/php-fpm.conf
cp\u00a0\/opt\/php-7.1\/etc\/php-fpm.d\/www.conf.default\u00a0\/opt\/php-7.1\/etc\/php-fpm.d\/www.conf<\/p>\n

Open \/opt\/php-7.1\/etc\/php-fpm.conf<\/span> and adjust the following setting (remove the ; in front of the pid line):<\/p>\n

nano \/opt\/php-7.1\/etc\/php-fpm.conf<\/p>\n

[...]
\npid = run\/php-fpm.pid
\n[...]<\/pre>\n
Then open \/opt\/php-7.1\/etc\/php-fpm.d\/www.conf<\/span>\u00a0and adjust the <\/span>listen<\/span> line, you must use an unused port (e.g. <\/span>8999<\/span>; port <\/span>9000<\/span> might be in use by Debian’s default PHP-FPM already):<\/span><\/p>\n
nano\u00a0\/opt\/php-7.1\/etc\/php-fpm.d\/www.conf<\/p>\n
[...]
\nlisten = 127.0.0.1:8999
\n[...]<\/pre>\n
3.1 Create the systemd unit file<\/h3>\n
Next, we’ll create the system unit file which is used to start and stop the PHP-FPM daemon.<\/p>\n
nano\u00a0\/lib\/systemd\/system\/php-7.1-fpm.service<\/p>\n
with the following content:<\/p>\n

Enable the service and reload systemd:<\/p>\n
systemctl enable php-7.1-fpm.service<\/span>
systemctl daemon-reload<\/p>\n
Finally, start PHP-FPM.<\/p>\n
systemctl start php-7.1-fpm.service<\/p>\n
To enable the Zend OPcache, open \/opt\/php-7.1\/lib\/php.ini<\/span>…<\/p>\n
nano \/opt\/php-7.1\/lib\/php.ini<\/p>\n
… and add the following line at the end:<\/p>\n
[...]
\nzend_extension=opcache.so<\/pre>\n
3.2 Enable Memcache (optional)<\/h3>\n
In this chapter, I will compile and enable the PHP Memcached extension.<\/p>\n
The first step is to install the\u00a0libmemcached-dev package from Debian.<\/span><\/p>\n
apt-get install libmemcached-dev<\/p>\n
Then create a diretory, download the PHP memcache extension from Github, unpack the archive and enter the directory that contains the unpacked files.<\/p>\n
mkdir \/usr\/local\/src\/php7.1-build\/php-memcache
cd \/usr\/local\/src\/php7.1-build\/php-memcache
wget https:\/\/github.com\/php-memcached-dev\/php-memcached\/archive\/php7.zip
unzip php7.zip
cd php-memcached-php7<\/p>\n
Prepare he sources by running the phpize command from PHP 7.1.<\/p>\n
\/opt\/php-7.1\/bin\/phpize<\/p>\n
Configure and build the PHP memcache extension.<\/p>\n
.\/configure –with-php-config=\/opt\/php-7.1\/bin\/php-config
make
make install<\/p>\n
To enable the Memcache extension, open\u00a0<\/span>\/opt\/php-7.1\/lib\/php.ini<\/span>…<\/p>\n
nano \/opt\/php-7.1\/lib\/php.ini<\/p>\n
… and add the following line at the end:<\/p>\n
[...]
\nextension=memcached.so<\/pre>\n
3.3 Install xDebug extension (optional)<\/h3>\n
The\u00a0<\/span>xDebug<\/a>\u00a0module is a debugging extension for PHP. The installation is optional.<\/p>\n
Install xDebug with these commands.<\/p>\n
cd \/opt\/php-7.1\/etc
pecl -C .\/pear.conf update-channels
pecl -C .\/pear.conf install xdebug<\/p>\n
Then edit the php.ini file with an editor:<\/p>\n
nano \/opt\/php-7.1\/lib\/php.ini<\/p>\n
and add the following line at the end of the file:<\/p>\n
zend_extension=\/opt\/php-7.1\/lib\/php\/extensions\/no-debug-non-zts-20160303\/xdebug.so<\/pre>\n
Finally restart the php-fpm daemon:<\/p>\n
systemctl start\u00a0<\/span>php-7.1-fpm.service<\/span><\/p>\n
Test the PHP version:<\/p>\n
cd\u00a0\/opt\/php-7.1\/bin
.\/php –version<\/p>\n
The output should be similar to this screenshot.<\/p>\n
\"PHP<\/a><\/p>\n
Please note:<\/strong> The screenshot is from PHP 7.1.14,\u00a0the tutorial gets updated continuously for new PHP versions but we don’t take new screenshots each time, so the PHP version that you will see on your server might be newer.

Enable the service and reload systemd:<\/p>\n
systemctl enable php-5.6-fpm.service<\/span>
systemctl daemon-reload<\/p>\n
Finally, start PHP-FPM.<\/p>\n
systemctl start php-5.6-fpm.service<\/p>\n
To enable the Zend OPcache, open\u00a0<\/span>\/opt\/php-5.6\/lib\/php.ini<\/span>…<\/p>\n
nano \/opt\/php-5.6\/lib\/php.ini<\/p>\n
… and add the following line at the end:<\/p>\n
[...]
\nzend_extension=opcache.so<\/pre>\n
5.2 Enable Memcache (optional)<\/h3>\n
In this chapter, I will compile and enable the PHP Memcached extension.<\/p>\n
The first step is to install the\u00a0libmemcached-dev package from Debian.<\/span><\/p>\n
apt-get install libmemcached-dev<\/p>\n
Then\u00a0run these commands to build the memcache extension<\/p>\n
cd \/opt\/php-5.6\/etc<\/span>
pecl -C .\/pear.conf update-channels<\/span>
pecl -C .\/pear.conf install\u00a0memcache<\/span><\/p>\n
To enable the Memcache extension, open\u00a0<\/span>\/opt\/php-5.6\/lib\/php.ini<\/span>…<\/p>\n
nano \/opt\/php-5.6\/lib\/php.ini<\/p>\n
… and add the following line at the end:<\/p>\n
[...]
\nextension=memcache.so<\/pre>\n
Finally restart the php-fpm daemon:<\/p>\n
systemctl start\u00a0<\/span>php-5.6-fpm.service<\/span><\/p>\n
Test the PHP version:<\/p>\n
cd\u00a0\/opt\/php-5.6\/bin
.\/php –version<\/p>\n
The output should be similar to this screenshot.<\/p>\n
\"PHP<\/a><\/p>\n
Please note:<\/strong>\u00a0<\/span>The screenshot is from PHP 5.6.33,\u00a0the tutorial gets updated continuously for new PHP versions but we don’t take new screenshots each time, so the PHP version that you will see on your server might be newer. The current version of this tutorial is for\u00a0php-5.6.33.<\/span><\/p>\n
5.4 Enable PHP 5.6 in ISPConfig<\/h3>\n
In ISPConfig 3.1, you can configure the new PHP version under\u00a0<\/span>System > Additional PHP Versions<\/span>. On the\u00a0<\/span>Name<\/span>\u00a0<\/span>tab, you just fill in a name for the PHP version (e.g.\u00a0<\/span>PHP 5.6<\/span>) – this PHP version will be listed under this name in the website settings in ISPConfig:<\/p>\n
\"PHP<\/a><\/p>\n
Go to the\u00a0<\/span><\/span>FastCGI Settings<\/span>\u00a0<\/span>tab\u00a0<\/span><\/span>and fill out the fields as follows:<\/span><\/p>\n
Path to the PHP FastCGI binary:<\/strong>\u00a0\/opt\/php-5.6\/bin\/php-cgi
Path to the php.ini directory:<\/strong>\u00a0\/opt\/php-5.6\/lib<\/span><\/p>\n
\"PHP<\/a><\/p>\n
Then g\u00a0to the\u00a0<\/span>PHP-FPM Settings<\/span>\u00a0<\/span>tab\u00a0and fill out the fields as follows:<\/p>\n
Path to the PHP-FPM init script:<\/strong>\u00a0php-5.6-fpm
Path to the php.ini directory:<\/strong>\u00a0\/opt\/php-5.6\/lib
Path to the PHP-FPM pool directory:<\/strong>\u00a0\/opt\/php-5.6\/etc\/php-fpm.d
