    • Nginx Version Installed: i.e. 1.19.3
    • PHP Version Installed: i.e. 7.4.11
    • MariaDB MySQL Version Installed: i.e. not sure, installed today oct 20,2020
    • When was last time updated Centmin Mod code base ? : i.e. run centmin.sh menu option 23 submenu option 2 or cmupdate command
    • Persistent Config: Do you have any persistent config file options set in /etc/centminmod/custom_config.inc ? You can check via this command:
      Code (Text):
      cat /etc/centminmod/custom_config.inc

      Post output in CODE tags.

    I said NO to zend cache (this is a Wordpress server), and I said Yes to xcache, it causes some problems, Xcache 3.2 was not installed because no file was found on lighttpd.net server, is Xcache not compatible with php 7.4.11? I tried to replace with APC and it said APC was not compatbile with php 7.4, told me to use Zend optimizer instead (which supposedly is Not compatible with wordpress sites.


    So what is the correct cache to use with wordpress 5.5.1 on php 7.4.11?

    Yeah for best performance Zend Opcache is usually recommended and for compatibility reasons. I'll have to revisit the APC and XCache routines to see about either updating them or removing them as I haven't used the in almost 8 years now !

    Hello

    For my case removing APC and Xcache and adding on the main menu the Redis installation it will be much better !

    Thank you

    How do I remove xcache completely as after recompiling php it's asking to re-install xcache but it's not available anymore (errror 404)?

    You should be able to just run centmin.sh menu option 12, submenu option 1 or 2

    Option 12 is Zendcache not xcache

    Xcache is option 8. All it does is trying to reinstall xcache which is unavailable:

    Code:
    Enter option [ 1 - 24 ] 8

    How do I manually remove xcache and make sure php does not try to load this extension?

    when you run centmin.sh menu option 12 to install Zend Opcache, it automatically removes Xcache. Zend Opcache is the recommended optimal Zend Opcache replacement for Xcache.

    oh ok, got you. The thing is, this is a staging server where we don't need any caching

    Then you can disable Zend Opcache from loading the extension via custom .ini settings.

    For custom php settings read centminmod.com/phpfpm.html#customphpini. You might want to create /etc/centminmod/php.d/b_customphp.ini to override centmin mod defaults at /etc/centminmod/php.d/a_customphp.ini and restart PHP-FPM. Such changes will persist when doing centmin mod upgrades.

    Also outlined in Getting Started Guide Step 17

    So specifically for zendopcache.ini you want to override it with a file you create named alphabetically listed after it i.e. zz_zendoptcache.ini

    copy and make /etc/centminmod/php.d/zz_zendopcache.ini
    Code (Text):
    cp -a /etc/centminmod/php.d/zendopcache.ini /etc/centminmod/php.d/zz_zendopcache.ini

    edit /etc/centminmod/php.d/zz_zendopcache.ini and comment out the zend_extension load line with semi-colon in front
    Code (Text):
    ;zend_extension=opcache.so

    then restart php-fpm service
    Code (Text):
    service php-fpm restart

    or via command shortcut
    Code (Text):
    fpmrestart


    If you want to re-enable Zend Opcache, just either delete /etc/centminmod/php.d/zz_zendopcache.ini and then restart PHP-FPM service again.
