I installed NextCloud and in the summary window it keeps telling me that my OPCache is not enabled. I have enabled it and I am seeing conflicting information about if it really is enabled or not.
Ubuntu 18.04.1 | PHP 7.2.11-2
$ sudo cat /etc/php/7.2/apache2/php.ini | grep opcache

Then finally, looking at a phpinfo() generated page, I see it loading the php.ini file from the correct one I have edited from the first block. The only additional .ini file it is loading is from the mods-available folder:
$ sudo cat /etc/php/7.2/mods-available/opcache.ini
; configuration for php opcache module
; priority=10
zend_extension=/usr/lib/php/20170718/opcache.so
There isn't any of the settings in that file, so the only file I see those settings in is the php.ini file, which is the same one being loaded from phpinfo(). These settings have been set for a while too, I am just now noticing they weren't taking affect. So the apache server has been rebooted with these settings saved. What am I missing here?
Edit:
Here are some screenshots of the phpinfo() screen for further clarification:
I don't have enough reputation point to add this as a comment, so I'm adding it as an answer. Can you please run php -a
and then run the following command to see what it says:
print_r(opcache_get_configuration());
It should usually show something like this:
Array
(
[directives] => Array
(
[opcache.enable] => 1
[opcache.enable_cli] =>
[opcache.use_cwd] => 1
[opcache.validate_timestamps] => 1
[opcache.validate_permission] =>

[opcache.inherited_hack] => 1

)

(
[version] => 7.2.10-0ubuntu0.18.04.1
[opcache_product_name] => Zend OPcache
)
[blacklist] => Array
(
)
)
if you find opcache.enable is true (as it is in this example), then it's enabled. However, it's not enabled for cli.
Well after playing around for a few hours, I think I figured it out. In par with what @Sammitch said. When I was doing an apt-get update, it was installing 7.3 php files for some reason. So I purged those and verified my config for php was set to default to 7.2 and then did another update and autoremove. That seemed to clear that confusion up. Not sure how that happened though.
