Install Memcached on cPanel server

Enabling caching is one of the factor that includes in optimizing a webserver. Caching technology is a main paramter. Memcache is a popular type of caching method used. Memcache is an open source caching system to speed-up dynamic website applications. For the proper functioning of Memcache, its daemon memcached is needed. Here I am explaining the installation steps of Memcache and Memcahed in the server.

Memcache is a type of caching. memcached daemon is needed for the functioning of Memcache. For that, first we need to install memcached daemon.

# yum install memcached

Then, start memcached service

# service memcached start


root@server [~]# service memcached start
Starting memcached: [ OK ]

Then, install PHP memcache

# pecl install memcache


We can install memcache from the source by following the steps below:

# wget
# tar -xvzf memcache-3.0.8.tgz
# cd memcache-3.0.8
# phpize

Then, you can see something like this:

# phpize
Configuring for:
PHP Api Version:         20100412
Zend Module Api No:      20100525
Zend Extension Api No:   220100525
# ./configure
# make
# make install

Make sure memcache module is present in php.ini file. If not, add the memcache extension in php.ini file.

# echo "" >> /usr/local/lib/php.ini

Finally, restart Apache

# service httpd restart

Make sure memcached will be up even after a server reboot:

# chkconfig --levels 235 memcached on

How to check if memcache is installed or not?

root@server [~]# php -m | grep memcache
