Disable nginx and php caching

what are you trying to do ??? for development work without caching ? changes to what css, js or php code ?

for php code, all you need to make php changes show up instantly is either do a php-fpm restart or set for Zend Opcache related cache, the revalidate frequency to something lower than 180 seconds

• PHP: OPcache - Manual
• PHP: Runtime Configuration - Manual

To customise Zend Opcache settings see the instructions to create your own .ini settings file to retain the changes at https://centminmod.com/phpfpm.html#customphpini

---

Example order of php .ini files applied via php --ini command

Code (Text):

php --ini
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini
Scan for additional .ini files in: /etc/centminmod/php.d
Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
/etc/centminmod/php.d/curlcainfo.ini,
/etc/centminmod/php.d/geoip.ini,
/etc/centminmod/php.d/igbinary.ini,
/etc/centminmod/php.d/imagick.ini,
/etc/centminmod/php.d/mailparse.ini,
/etc/centminmod/php.d/memcache.ini,
/etc/centminmod/php.d/memcached.ini,
/etc/centminmod/php.d/redis.ini,
/etc/centminmod/php.d/zendopcache.ini

If i want to override opcache.revalidate_freq 180 seconds default, I'd create a .ini file after /etc/centminmod/php.d/zendopcache.ini alphabetically i.e. /etc/centminmod/php.d/zzendopcache.ini

So ordered after zendopcache.ini

Code (Text):

php --ini
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini
Scan for additional .ini files in: /etc/centminmod/php.d
Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
/etc/centminmod/php.d/curlcainfo.ini,
/etc/centminmod/php.d/geoip.ini,
/etc/centminmod/php.d/igbinary.ini,
/etc/centminmod/php.d/imagick.ini,
/etc/centminmod/php.d/mailparse.ini,
/etc/centminmod/php.d/memcache.ini,
/etc/centminmod/php.d/memcached.ini,
/etc/centminmod/php.d/redis.ini,
/etc/centminmod/php.d/zendopcache.ini,
/etc/centminmod/php.d/zzendopcache.ini

In /etc/centminmod/php.d/zzendopcache.ini add value say 10 seconds

Code (Text):

opcache.revalidate_freq = 10

Note though reducing revalidation frequency lowers performance of caching all the time 24/7. Best way is just to restart php-fpm and nginx after file updates which are done manually via command shortcut

Code (Text):

nprestart

After restart recheck value is now at 10 seconds

Code (Text):

php --ri 'Zend OPcache'

Any php related setting can override and customised this way as well

 

then just comment out staticfiles.conf include file and create /etc/centminmod/php.d/zzendopcache.ini file to override /etc/centminmod/php.d/zendopcache.ini and in /etc/centminmod/php.d/zzendopcache.ini set

Code (Text):

opcache.enable=0

which will disable PHP Zend Opcache and you can keep Zend Opcache installed but disable

keep Zend Opcache installed via centmin.sh menu option 5 and just disable it via .ini settings override

If it's related to troubleshooting wp plugins, see Wordpress - Wordpress 403 Permission Denied Errors centmin.sh menu option 22 wordpress has whitelist restrictions to plugins you need to whitelist as the page builder probably being blocked

 

probably best to start a thread in Blogs & CMS usage it could be related to autoprotect tool too blocking your page builder
