    relates to saving php sessions for all PHP apps

    only PHP-FPM needs restart and check memcached stats page PHP Opcode and Memcached statistics pages | Centmin Mod Community

    variable / slab id and their respective items contents and item names - of course you need to know the item names for your sessions too and that depends on PHP app

    also session sizes usually very small so unless you have millions of concurrent sessions you probably won't notice much difference in sizes

    for example, xenforo forum session size is around 223 bytes

    And when memcached or server restarted the forum users will just have to login again to the forum or i will have more problems with it?

    Thanks

    Depends on session cache length which for forums usually 900 seconds... so really should not matter on invalidation of cache on memcached restarts. This forum uses memcached sessions and have you had trouble with logins ? Not that often do I restart memcached though

    current uptime for memcached her eis ~20 days or 1,783,639 seconds

    As i can see there is already a related file named "a_customphp.ini" so is it better to edit this file or rename it or delete this one and use a new one with another name?

    It seems that this file is replaced as i can see a backup of it and i don't want to be replaced with a new one as the point of this file is to not get replaced.....:

    Code:
    a_customphp.ini-bak_240215-211438
    a_customphp.ini-bak_240315-233535

    yes editing /etc/centminmod/php.d/a_customphp.ini is best if you want to keep customisations between PHP upgrades and no /etc/centminmod/php.d/a_customphp.ini is not replaced, the backups you see are part of the full backup PHP upgrades do regardless of overwrites

    For updating the Opcache size, should I do it via /etc/centminmod/php.d/zendopcache.ini or by adding a "opcache.memory_consumption=100" line to the a_customphp.ini file? I'm on .08 beta2

    Makes sense to do it in zendopcache.ini to me--that way I'm not confused later to see a different value there than in my opcache status page because I've forgotten that it's getting overriden. :facepalm:

    However, if I do that, will the customization get wiped out when updating php via centminmod?

    Only time zendcopcache.ini gets wiped is on major PHP upgrades i.e. 5.4 to 5.5 to 5.6 to 5.7/7 etc see code at lines 24-54 of inc/zendopcache_upgrade.inc and gets re-created at lines 155-180 of inc/zendopcache_upgrade.inc. This is so I can recalculate the zend_extension directory path which changes on major PHP version upgrade/downgrades

    i.e.

    Code:
    PHPEXTDIRD=`cat /usr/local/bin/php-config | awk '/^extension_dir/ {extdir=$1} END {gsub(/\047|extension_dir|=|)/,"",extdir); print extdir}'`
    Code:
    zend_extension=${PHPEXTDIRD}/opcache.so
    Code:
    echo zend_extension=${PHPEXTDIRD}/opcache.so
    zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20131226/opcache.so
    I guess it would't be that hard to transplant the memory allocation value for opcache.memory_consumption from old to new zendopcache.ini something I'll look into :)

    edit: fixed and added commit to ensure zend opcache memory allocation value persists on PHP major version upgrades Ensure Zend Opcache memory allocation value persists on PHP major upg… · centminmod/[email protected] · GitHub :)

    Thanks.

    Not a big deal for me, I've got an Ansible task that makes sure it's set to my specified value that runs as part of my suite of plays:).

    I'm trying to add a directory into the open_basedir path in the php.conf file but I found it got overwritten everytime I update.
    Is there a way to keep this custom value?
    I use this for the XF addon that creates backup.
    fastcgi_param PHP_ADMIN_VALUE open_basedir=$document_root/:/usr/local/lib/php/:/tmp/:/home/nginx/domains/backup/;

    When you upgrade or downgrade PHP, do you answer yes to overwrite php.conf ? that's why, if you answer no to overwrite, then you custom settings are retained

    Code:
    Update & overwrite your existing php-fpm.conf [y/n]:
    If you want to customise the base php.conf template located in Centmin Mod zip file at config/nginx/php.conf or on live server install at
    /usr/local/src/centmin-v1.2.3mod for .07 stable or /usr/local/src/centminmod-123.08centos7beta02 for .08 beta 02 so every overwrites have your custom /usr/local/nginx/conf/php.conf include file settings, you need to edit the Centmin Mod codes base config/nginx/php.conf template (inc/php_upgrade.inc line 419 to 426 is function that copies that base config/nginx/php.conf template to live location at /usr/local/nginx/conf/php.conf when you answer yes to overwrite /usr/local/nginx/conf/php.conf).
    Code:
    cp -f $CUR_DIR/config/nginx/php.conf /usr/local/nginx/conf/php.conf
    The base template config/nginx/php.conf can be also see on github hosted code at centminmod/php.conf at 123.08centos7beta02 · centminmod/centminmod · GitHub
