How to Enable OPcache in DirectAdmin

OpCache is a PHP extension that improves the performance of PHP applications. It works by caching compiled code in shared memory. As a result, the code can be executed faster on subsequent requests, since the code is not recompiled each time it is executed.

On the other hand, DirectAdmin is a web hosting control panel. It allows users to manage their web hosting environment. Furthermore, it includes support for PHP and allows users to configure their PHP environment.

In fact, enabling OPcache on a DirectAdmin server helps improve the performance of PHP applications running on that server. In other words, caching the compiled PHP code in memory allows OpCache to reduce the amount of time taken to execute PHP scripts. As a result, this leads to faster page load times and improved overall server performance.

How to enable Opcache

Before enabling OPcache we have to ensure the the module is installed. This can be done with these commands:

php -v

OR

php -m | grep OPcache

If the output of the above commands do not return a result, we have to install the module.

Next, it is time to install OPcache in DirectAdmin via CustomBuild GUI Plugin

1. First, we have to login into the DirectAdmin control panel.
2. Then, head to CustomBuild 2.0 under Extra Features.
3. After that, go to Build Software and click the Build button next to Build opcache in the list.
4. At this point, we will be able to see the Opcache installation progress.

Alternatively, we can enable OPcache via CLI, by running these commands as the root user via SSH:

cd /usr/local/directadmin/custombuild
./build set opcache yes
./build opcache


Then, we can confirm the installation as seen below:

/usr/local/phpxx/bin/php -m | grep -i opcache

Remember to replace xx with the php version details.

Similarly, we can confirm the installation by creating a phpinfo.php page and checking it from a browser.
