How to install OPcache in DirectAdmin with CustomBuild?

If you want to install OPcache on a DirectAdmin server you can use the instructions below. First, check whether it is already installed, to avoid losing the previous customizations you have applied. Run the following command to check (## represents the PHP version) for each installed PHP version:

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

Install OPcache via CLI

To install OPcache on a DirectAdmin server, use CustomBuild to complete the installation by running the following commands from the SSH console as root user:

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

Confirm the installation as follows. Replace ## with PHP version.

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

To check PHP versions 5.6 and 7.3, run the following command:

/usr/local/php56/bin/php -m  | grep -i opcache
/usr/local/php73/bin/php -m  | grep -i opcache

Alternatively, to verify all installed PHP versions simultaneously run the following command:

for each in $(ls -lah /usr/local/ | grep -Po 'php[\d][\d]'); do printf "$each :\n";  /usr/local/$each/bin/php -m  | grep -i opcache ;done
