Create a Systemd unit file

Create the systemd unit file:

nano /lib/systemd/system/php-7.1.19-fpm.service

And let's put the following content and save it:

[Unit]
Description=The PHP 7.1.19 FastCGI Process Manager
After=network.target

[Service]
Type=simple
PIDFile=/opt/php-7.1.19/var/run/php-fpm.pid
ExecStart=/opt/php-7.1.19/sbin/php-fpm --nodaemonize --fpm-config /opt/php-7.1.19/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

Then enable the service and reload the systemd-t:

systemctl enable php-7.1.19-fpm.service
systemctl daemon-reload

And let's start PHP-FPM:

systemctl start php-7.1.19-fpm.service

PHP-FPM can be easily verified by the following command:

ps -axf | grep fpm

29126 pts/0    S+     0:00  |                       \_ grep fpm
  979 ?        Ss     0:00 php-fpm: master process (/etc/php5/fpm/php-fpm.conf)
  982 ?        S      0:00  \_ php-fpm: pool www
  983 ?        S      0:00  \_ php-fpm: pool www
28978 ?        Ss     0:00 php-fpm: master process (/opt/php-7.1.19/etc/php-fpm.conf)
28979 ?        S      0:00  \_ php-fpm: pool www
28980 ?        S      0:00  \_ php-fpm: pool www

The output of the command shows nicely that the basic PHP5-FPM is running and the www pool of PHP-FPM 7 has started next to it.

Enable Zend OPcache

Edit the /opt/php-7.1.19/lib/php.ini file:

nano /opt/php-7.1.19/lib/php.ini

And add the following line to the very end:

zend_extension=opcache.so

We test:

/opt/php-7.1.19/bin/php --version

PHP 7.1.19 (cli) (built: Jul  7 2018 00:12:44) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.1.19, Copyright (c) 1999-2018, by Zend Technologies

Enable Memcache (Optional)

Install the following packages below apt-get command:

apt-get install libmemcached-dev pkg-config

Create the directory and download the wget command to extract the memcache plugin from Github, and unzip the directory:

mkdir /usr/local/src/php7-build/php-memcache
cd /usr/local/src/php7-build/php-memcache
wget https://github.com/php-memcached-dev/php-memcached/archive/php7.zip
unzip php7.zip
cd /usr/local/src/php7-build/php-memcache/php-memcached-php7

Prepare the source for the new (7.1.19) PHP phpize command:

/opt/php-7.1.19/bin/phpize

Correct output:

Configuring for:
PHP Api Version:         20160303
Zend Module Api No:      20160303
Zend Extension Api No:   320160303

Configuration and translation:

./configure --with-php-config=/opt/php-7.1.19/bin/php-config
make
make install

To enable the memcache extension, edit the php.ini file again:

nano /opt/php-7.1.19/lib/php.ini

And add the following line to the end:

extension=memcached.so

Enable PHP 7.1.19 in ISPConfig

Let's step in ISPConfigba, then let's go to System -> Additional PHP Versions menu.

Here, click the Add new PHP version button, then fill in the fields on the first tab (Name) as follows:

• Server: From here, select your server from the drop-down list
• Client: Leave this blank so all PHP clients will have access to this version of PHP
• PHP Name: Here, you should enter the exact version here, so if you install more versions later, there will be no confusion.

Then click on FastCGI settings tab:

• Path to the PHP FastCGI binary: / Opt / php-7.1.19 / bin / php-cgi
• Path to the php.ini directory: / opt / php-7.1.19 / lib

Go to the PHP-FPM Options tab:

• Path to the PHP-FPM init script: php-fpm-7.1.19
  (Note here that it does not start with / since we did not create an init.d startup file but a systemd unit file)
• Path to the php.ini directory: / opt / php-7.1.19 / lib
• Path to the PHP-FPM Pool directory: /opt/php-7.1.19/etc/php-fpm.d

Finally, save it.

Rotate Log Files (Optional)

You should consider rotating the log files with Logrotate. If we want to set it up, in this description we can find a way.

Conclusion

So we have created a new optional PHP version that can be enabled separately for any web page in the web page settings. This allows web pages to run independently with different versions of PHP.
