How to install Memcached on CentOS

Memcached (Daemon) Installation on CentOS:

1. Try to install with yum:

   # yum install libevent libevent-devel

   If this succeeds skip to #5. If this fails, then let’s compile. Download and extract the latest stable version:

   # cd /usr/local/src && wget http://monkey.org/~provos/libevent-2.0.14-stable.tar.gz && tar -xzf libevent-2.0.12-stable.tar.gz && cd libevent-2.0.12-stable

2. Let’s compile:

   # ./configure && make && make install

3. In the output you should see:

   Libraries have been installed in: /usr/local/lib

   If so you can:

   # echo "/usr/local/lib/" > /etc/ld.so.conf.d/libevent.conf

4. Configure your server for the new install:

   # ldconfig -v

5. Now find the latest stable memcached, download and extract:

   # cd /usr/local/src && wget http://memcached.googlecode.com/files/memcached-1.4.6.tar.gz && tar -xzf memcached-1.4.6.tar.gz && cd memcached-1.4.6

6. Let’s compile:

   # ./configure && make && make install

7. Make sure memcached is starts automatically on server boot:

   # touch /etc/init.d/memcached
   # echo '#!/bin/sh -e' >> /etc/init.d/memcached
   # echo '/usr/local/bin/memcached -d -m 128 -p 11211 -u nobody -l localhost' >> /etc/init.d/memcached
   # chmod u+x /etc/init.d/memcached
   # echo '/etc/init.d/memcached' >> /etc/rc.local

8. And finally, let’s start memcached:

   # /etc/init.d/memcached
