Other than the opcache what can require php-fpm to be restarted to see changes?

I have opcache setup as follows:

; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
opcache.validate_timestamps=1

; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only
; once per request. "0" means always validate)
opcache.revalidate_freq=0

When deploying changes, I find that I still need to restart php-fpm to see them.

What other settings should I be investigating?

Solution

  • opcache.revalidate_path

    Check the value of this setting. If it is set to 0, OPcache will not check file timestamps for changes at all, which could explain why you are not seeing the changes. Make sure it is set to 1.

    You could also verify opcache.max_accelerated_files, opcache.validate_permission & opcache.fast_shutdown
