Installing memcached On CentOS/RHEL

wget http://www.monkey.org/~provos/libevent-1.3e.tar.gz
tar zxvf libevent-1.3e.tar.gz
cd libevent-1.3e
 
./configure
make
make install

Install memcached

wget http://danga.com:80/memcached/dist/memcached-1.2.5.tar.gz
tar zxvf memcached-1.2.5.tar.gz
cd memcached-1.2.5
 
./configure
make
make install
