Install Zend OPcache in DirectAdmin

 

Zend OPcache is basically a modern PHP script caching module which helps to accelerate the PHP performance on the server. It gives a faster PHP execution through Opcode caching and optimization. It also improves the performance of PHP by storing the pre-compiled script code in the shared memory of the server.

 

This pre-compiled script codes will terminate reading the code from the disk and executing it on future accessing. Zend OPcache will also apply some code optimization pattern which helps to execute the code faster than the normal.

 

Install Zend OPcache

1) SSH to the server as root user.

2) Enter into the custom build directory. Which is located below.

# cd /usr/local/directadmin/custombuild

3) Set the OPcache to Yes.

# ./build set opcache yes

Now you will get an output as follows.

[root@user custombuild]# ./build set opcache yes

Changed opcache option from no to yes.

4) Run the below command to execute the OPcache module.

# ./build opcache

while executing, you will get an output like as follows.

[root@user custombuild]# ./build opcache

opCache 7.0.5 is now installed for PHP 5.5.

opCache 7.0.5 PHP extension has been installed successfully.

5) We can check that the OPcache is listing correctly in different ways.

Here I’m listing some of the commands to verify the same.

[root@user /]# php -v
