How to install memcached on CentOS

Before we install memcached we need a dependency library libevent. Check for latest stable version at http://monkey.org/~provos/libevent/

cd /usr/local/src
wget http://monkey.org/~provos/libevent-1.4.13-stable.tar.gz
tar -xzvf libevent-1.4.13-stable.tar.gz
cd libevent-1.4.13-stable
./configure --prefix=/usr/local
make
make install
cd ..

Now lets install memcached. Check for latest stable version at http://memcached.org/

wget http://memcached.googlecode.com/files/memcached-1.4.4.tar.gz
tar -xzvf memcached-1.4.4.tar.gz
cd memcached-1.4.4
LDFLAGS='-Wl,--rpath /usr/local/lib' ./configure --prefix=/usr/local
make
make install

More information about LDFLAGS http://en.wikipedia.org/wiki/Linker

Run memcached as a daemon. Basic options: d = daemon, m = memory, u = user, l = IP to listen to, p = port

memcached -u root -d

or

memcached -u root -d -m 512 -l 127.0.0.1 -p 11211

To stop daemon type

pkill memcached

Now we’re off to installing php extension memcache.
