Let us take a look at Enabling and configuring Php OPcache on Ubuntu.

Enabling Php Opcache on ubuntu

OPcache is a PHP interpreter Apache module. It improves performance by storing precompiled scripts in shared memory. It is commonly used to improve the performance of WordPress and PHP-based apps. The use of OPcache eliminates the need for PHP to load and parse scripts on each request.

To begin with, Php enables OPcache ubuntu, to establish an SSH connection to the server. Use the following command to open the PHP configuration file. This is the first step in enabling PHP OPcache on Ubuntu.

If the Apache module is used to interpret PHP:

$ sudo nano /etc/php/7.4/apache2/php.ini

If PHP is being interpreted by PHP-FPM or NGINX:

$ sudo nano /etc/php/7.4/fpm/php.ini

To enable the use of OPcache, simply enable the related item by changing the following line:

;opcache.enable=0 with the code gievn below

opcache.enable=1

The user must remove the; initial if it is present. And, the OPache will already be enabled at this point when restarting the web server:

Apache

$ sudo service apache2 restart

PHP-FPM / NGINX:

$ sudo service nginx restart

Create the phpinfo.php file in the folder containing the website and add the following code there to verify that OPcache is functioning properly now.

After that, save the document and open it in a browser. The presence of the OPcache section, as seen in this image, indicates that OPcache is operational.

RAM memory to use for Php enable OPcache on ubuntu

In this instance, the user must find the ideal balance between the RAM memory that OPCache will use and the desired speed. Since OPCache also saves the infrequently used instructions, an expanded memory doesn’t always translate into an actual performance improvement. The allocated memory will be wasted as a result, with no improvement in performance.

Note that for general use, it is advised to alter the default value (64 MegaBytes).

;opcache.memory_consumption=64 as follows, into 128 MegaBytes opcache.memory_consumption=128. The user must then increase this value by confirming the performance of the outcome.

The number of scripts to be stored

The user can specify the number of scripts to be stored in the cache in addition to the memory that is available through OPcache. Normally, this value can be left as default (2000). However, if the user’s application’s hit rate is below 100%, the user can attempt to raise it in accordance with their needs by uncommenting the following line:

;opcache.max_accelerated_files=2000 and boost the value in the following way:

opcache.max_accelerated_files=3000

The frequency of updates

The stored scripts are periodically checked for updates by OPcache. The following instruction can be changed to determine the assessment period: ;opcache_revalidate_freq = 2, as well as the default setting (in seconds): opcache_revalidate_freq = 100

Applying changes

Restart the webserver to confirm the changes.

Apache: $ sudo service apache2 restart

NGINX: $ sudo service nginx restart

OPcache will then begin to save user scripts. This is the final step in enabling php OPcache in Ubuntu.
