PHP-FPM Transfer all my custom changes from php.info to php-fpm config

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

 

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

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

 

either but i usually do it via /etc/centminmod/php.d/zendopcache.ini myself

 

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/centminmod@48179c8 · GitHub

 

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
