Question

How to install/remove additional PHP versions provided by Plesk?

Answer

Additional PHP versions can be installed/removed by a Plesk administrator only. This can be done either via a Plesk interface (web-browser) or a command-line interface directly on a Plesk server.

Note: Modern operating systems do not support PHP 5.6 and lower versions. Visit this KB article for details.

 

Installing/removing additional PHP versions via the Plesk interface

 

Note: Make sure that port 8447 is opened in firewall. If it is closed and cannot be opened, use the command-line instructions.

  1. Log in to Plesk.

  2. In Plesk, go to Tools & Settings and click Updates (Updates and Upgrades).

  3. On the Updates and Upgrades page, click Add/Remove Components.


    Screenshot_2019-12-04_Plesk_Installer.png

  4. On the Add/Remove Components page, expand:

    • Web hosting > PHP interpreter versions section, if this is a Linux server.

    • Plesk hosting feature section, if this is a Windows server.

  5. Select required PHP versions for installation/uninstallation and click Continue.

 

Installing/removing additional PHP versions via a command-line interface

  1. Connect to a Plesk server via SSH (Linux) / RDP (Windows Server).

  2. Get the list of all available Plesk components (on Windows Server, use a command prompt as an Administrator):

    MYSQL_LIN: plesk installer --select-release-current --show-components

  3. Install/remove additional PHP versions using the component name from step 2.

     

    Example of the command to install PHP 7.4:

    Note: PHP 7.4 is available starting from Plesk Obsidian 18.0.21 Update 4.

    • for Linux:

      # plesk installer add --components php7.4

    • for Windows Server:

      C:\> plesk installer add --components php74

       

    Example of the command to remove PHP 5.6:

    • for Linux:

      # plesk installer remove --components php5.6

    • for Windows Server:

      C:\> plesk installer remove --components php56

    Hi - this is all fine for the FPM and CGI versions but how do you install the latest PHP-CLI builds?  I need these for running symphony etc apps.

    Hi @Hywel Jones,

    PHP-CLI should be there when you install it as additional component via Plesk. For example, on Debian 9:

    # apt search php-cli
    Sorting... Done
    Full Text Search... Done
    php-cli/stable,stable 1:7.0+49 all
    command-line interpreter for the PHP scripting language (default)
    php-cli-prompt/stable,stable 1.0.2+dfsg-1 all
    tiny helper prompting for user input
    plesk-php70-cli/stretch,now 7.0.32-debian9.0.18091413 amd64 [installed]
    Command-line interface for PHP
    plesk-php71-cli/stretch,now 7.1.22-debian9.0.18091413 amd64 [installed]
    Command-line interface for PHP
    plesk-php72-cli/stretch,now 1:7.2.10-debian9.0.18091411 amd64 [installed]
    Command-line interface for PHP

    # dpkg-query -L plesk-php72-cli
    /.
    /etc
    /etc/psa
    /etc/psa/php_versions.d
    /etc/psa/php_versions.d/plesk-php72-cgi.conf
    /etc/psa/php_versions.d/plesk-php72-fastcgi.conf
    /opt
    /opt/plesk
    /opt/plesk/php
    /opt/plesk/php/7.2
    /opt/plesk/php/7.2/bin
    /opt/plesk/php/7.2/bin/lsphp
    /opt/plesk/php/7.2/bin/phar.phar
    /opt/plesk/php/7.2/bin/php
    /opt/plesk/php/7.2/bin/php-cgi
    /opt/plesk/php/7.2/bin/phpdbg
    /opt/plesk/php/7.2/bin/phar

    So all binaries are located at /opt/plesk/php/7.2/bin/ (for PHP 7.2). This is actual for other operation systems as well.

    Thanks - that all works fine now - for some reason the day I made the query I was getting the PHP FPM version afting setting PATH=/opt/plesk/php/7.2/bin:$PATH and typing php -v - my Laravel artisan commands were failing with weird errors. Today it is all good !

    Hi @Richie Tjin,

    I've just checked it on Ubuntu 18 with Plesk Obsidian 18.0.21.4 and it shows for me. 
    Please try one more time.

    Note: php 7.4 isn't supported on CentOS 6, Red Hat Enterprise Linux 6, and CloudLinux 6.

    I has it in Plesk Obsidian 18.0.23 on Debian 8:

    Select the components you want to install:
    1. [=] PHP 7.4
    2. [=] PHP 7.3
    3. [ ] PHP 7.2
    4. [ ] PHP 7.1
    5. [ ] PHP 7.0
    ...

    Try to update Plesk to 18.0.23, if still isn't:

    # plesk installer upgrade 18.0.23

    So - I too am wanting PHP 7.4

    Thanks to Denis from above, I note that I can manually upgrade plesk using command line. 

     

    I'm left wondering why I can't see an upgrade being offered on the web interface? 

    Also the command to upgrade that is listed. Isn't working for me. 

    Error: `ERROR: Selector 'PLESK_18_0_28' does not match any product ID, release ID, release tier, or release version. Use either 'list' or 'list-all' command to list known entities.`

    It might be because operating system you have does not support 18 version. Please check for supported operating systems:

    https://docs.plesk.com/release-notes/obsidian/software-requirements/#s2

    Another reason might be custom repository, please check if it so using this article.

    Plesk 18 (Obsidian) doesn't use OS PHP. So, update Obsidian in case Plesk Onyx is used and feel free to remove OS PHP.
