Installing memcached on CentOS (cPanel)

Welcome to hell. No really, compared to installing memcached on Ubuntu, CentOSs really sucks. CentOS really sucks for package management.  Really sucks. Anyway, on to the point.

Here's how I installed memcached on CentOS, which I mainly use for cPanel.

LibEvent

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

wget http://www.monkey.org/~provos/libevent-1.4.13-stable.tar.gz
tar xvfz libevent-1.4.13-stable.tar.gz
cd libevent-1.4.13-stable
./configure && make && make install

Compile and Install Memcache

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

wget http://www.danga.com/memcached/dist/memcached-1.4.4.tar.gz
tar xvfz memcached-1.4.4.tar.gz
cd memcached-1.4.4
./configure && make && make install

If you are unlucky, you might need this line instead

./configure --with-lib-event=/usr/local && make && make install

This next bit is only required because the CentOS/memcached is nasty, test it.

memcached

If it works, great! Skip this next bit.
If it doesn't work and throws an error about shared libraries and such, you might need to do this

echo /usr/local/lib/ >> /etc/ld.so.conf.d/libevent-i386.conf

Now we need to make it start on bootup.

cp scripts/memcached.sysv /etc/init.d/memcached
chmod 755 /etc/init.d/memcached
mkdir /var/run/memcached
chkconfig memcached on
chkconfig --list | grep memcached

The last line should return "on" values for 0,2,3,4,5

Now you want to install the PHP extension for memcached? Har har. GLWT!
