How to add a custom PHP version in Plesk for Linux?
Warning: All the instructions below are to be performed at own will and risk. These steps are provided for demonstration purposes only and not supported by Plesk. Depending on the operating system and the desired configuration, installation steps might differ significantly. When installing an additional PHP version on the server, read the official PHP documentation on installation. It's recommended to perform the installation on a test environment before modifying the production environment.
On Linux systems, you can install any PHP version you need and then make it available in Plesk by registering it with the
plesk bin php_handler command-line utility.

Install the desired PHP version on the server. For installation guidelines, refer to the official PHP documentation available at http://php.net/manual/en/install.php. In brief, the installation includes the following main steps.
Connect to the server via SSH
Install C compiler and XML library with the following commands:
RHEL based OSes:
# yum install gcc -y && yum install libxml2-devel -y
Debian based OSes:
# apt-get install build-essential && apt-get install libxml2-dev
Download the PHP source you need from the official website (http://php.net/downloads.php or http://php.net/releases/) to the server and unpack it:
# gunzip php-NN.tar.gz
# tar -xf php-NN.tar
Configure and build PHP:
Note: In this step, it's possible to customize PHP with various options, such as specifying which extensions will be enabled in the compiled PHP version. Run
./configure --helpto see a list of the available options.
# cd ../php-NN
# ./configure --prefix /usr/local/phpNN --enable-fpm --with-fpm-group=www-data
# make install
Set up the
Note: Edit the
.inifile to set the desired PHP options. If it's required to configure the
php.inifile in another location, run the
configureutility with the option
--with-config-file-path=/some/pathin the previous step.
# cp php.ini-development /usr/local/lib/php.ini
Connect to the server via SSH
Register the new PHP version in Plesk:
Note: More information can be found with the following command:
plesk bin php_handler --help
2.1- CGI/FastCGI example:
# plesk bin php_handler --add -displayname <NN> -path <path to php-cgi binary> -phpini <path to php.ini> -type <php handler> -id <NN-custom> -clipath <path to php cli>
-displayname<NN>: It's the PHP version name that will be shown in the Plesk UI. It's recommended to include the version number in the
displayname, for example:
-path<path to php-cgi binary>: It's the location of the PHP CGI binary file. The location is shown in the output shown by the command
make installin the line Installing PHP CGI binary. For example, if the output contains the line Installing PHP CGI binary: /usr/local/bin/, the location to specify is /usr/local/bin/php-cgi. Learn more at: http://php.net/manual/en/install.unix.commandline.php
-clipath<path to php cli>: It's the location of the PHP CLI binary file. The location is shown in the output of the command
make installin the line Installing PHP CLI binary. For example, if the output contains the line Installing PHP CLI binary: /usr/local/bin/, the location to specify is /usr/local/bin/php. Learn more at: http://php.net/manual/en/install.unix.commandline.php
-phpini<path to php.ini>: It's the location of the
php.inifile, for example:
-type<php handler>: It's the type of the PHP handler associated with the installed PHP version. This example is for cgi , fpm or fastcgi PHP handlers and the mod_php is not supported
-id<NN-custom>: It's the identifier that will be used for referring to this PHP version when adjusting or removing it via
plesk bin php_handlersutility
2.2- FPM example (Notes: systemctl unit should also be created manually, if it specific for OS distribution; To add the PHP handler as a dedicated application, append '-fpm-dedicated' to the hander ID when registering; To add PHP as a 'usual' FPM application, add the handler second time, without the '-fpm-dedicated' ):
In order to manually create a service for the PHP handler the *.service file from the downloaded source needs to be copied to the local configuration
# cp /root/php-X.X/sapi/fpm/php-fpm.service /etc/systemd/system/php-fpm-X.X.service
enable and start the service:
# systemctl enable php-fpm-X.X.service
# systemctl start php-fpm-X.X.service
# systemctl status php-fpm-X.X.service
# plesk bin php_handler --add -displayname <NN> -path <path to php-fpm binary> -phpini <path to php.ini> -type fpm -id <NN-custom> -clipath <path to php cli> -service <PHP FPM service name> -poold <path to php-fpm.d pool folder>
-path<path to php-fpm binary>: It's the location of the PHP FPM binary file. The location is shown in the output shown by the command
make installin the line Installing PHP-FPM binary
-service<PHP FPM service name>: It's the PHP FPM service name
-poold<path to php-fpm.d pool folder>: It's the location containing the pool configuration files
Once the custom PHP versions are registered after applying the steps above, the custom PHP versions will be available:
Assign the custom PHP version:
Service Plan level: Go to Service Plans > Service Plan Name > PHP Settings
Domain level: Go to Domains > example.com > PHP Settings

Followng this article (and some additional help from https://talk.plesk.com/threads/unable-to-start-service-unable-to-manage-service-by-phpinimng.369863/) I was able to add and run PHP 7.1 (FPM) on a Plesk Obsidian 18.0.52 update3 (Debian 11.7).
However in the Plesk Tools&Settings / PHP settings / 7133-phpfpm page the EXTENSION TAB remains empty
Whatever I write in the PHP.ini (the second tab) phpinfo shows me that mysqli is not loaded.
I tried to add the following lines without success:
Maybe the solution was to compile the PHP 7.1 WITH the extensions as I could understand it on your § 1.4 but then what is the right syntax to add mysqli please?
I tried without success:
thanks for your help
