Install Memcache onto cPanel running CentOS

Every time I install Memcache on cPanel I get a little bit stuck, so I wrote this quick guide in the hopes of helping myself next time and also helping other people who want the advantages of super fast caching.

Make the Sources Folder

First of all lets make a folder to put all our sources in

mkdir ~/memcache

Compile and Install LibEvent

Memcache requires LibEvent. Go to their site and get the latest version.

cd ~/memcache
wget http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz
tar xvfz libevent-1.4.9-stable.tar.gz
cd libevent-1.4.9-stable
./configure; make; make install

Compile and Install Memcache

Now you can install Memcache. Again you should check their site for the latest version.

cd ~/memcache
wget http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz
tar xvfz memcached-1.2.6.tar.gz
cd memcached-1.2.6
./configure --with-lib-event=/usr/local/; make; make install

Starting Memcache

Try starting memcache.

memcached

If you get the following error then you may beed to register libevent:

error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory

Register LibEvent

vi /etc/ld.so.conf.d/libevent-i386.conf
--[paste]--
/usr/local/lib/
--[/paste]--
ldconfig

Installing PHP Memcache

Install the PHP Memcache extension. Check their site for the latest version.

cd ~/memcache
wget http://pecl.php.net/get/memcache-3.0.3.tgz
tar xvfz memcache-3.0.3.tgz
cd memcache-3.0.3
phpize
./configure
make
make install
vi /usr/local/lib/php.ini
--[paste]--
extension=memcache.so
--[/paste]--
service httpd restart

If you would like memcache to run as a service you may follow this post by Danny Bembibre:
