[VESTACP - 10] INSTALL MEMCAHED AND ZEND OPCACHE

As you may have heard about Memcached and Zend Opcache to support PHP's cache as it handled to save processing time. If you still do not know, then you can learn more about your caching forms.

In VestaCP, we can easily install Memcached and Zend Opcache with just two lines of code, so you should install it to support better website acceleration. In this article we will talk about using Memcached in WordPress, and Zend Opcache it self when PHP processing so we do not need to do anything. Install Memcached and use for WordPress To install Memcached for VestaCP, just run the following command: For CentOS / RHEL yum install --enablerepo = remi php-pecl-memcache memcached libmemcached -y For Ubuntu / Debian apt-get install memcached php5-memcache Starts Memcached service memcached start Automatically start memcached at boot (for CentOS) chconfig memcached trên Then restart Apache. With CentOS / RHEL service httpd restart With Ubuntu / Debian service apache2 restart If you use WordPress, install the Memcached is Your Friend plugin and do not need any further setup, you can track the cache information at Tools -> Memcached. Install Zend Opcache Just run the following command: yum install --enablerepo = remi php-pecl-zendopcache -y Then restart Apache. With CentOS / RHEL service httpd restart With Ubuntu / Debian service apache2 restart Finished, very simple right? Now try to visit the site again to see if the speed is improved, note that the first time after installing these will be a bit longer. Also note that when using Memcached, the VPS will cost you more RAM as buffer data will be stored in RAM to speed up access rather than write to the drive, but do not worry that the website will. It collapses due to lack of RAM because it frees itself when needed, and in Linux in general RAM is always used if it is empty.
