how to install memcached on centos

You can use the command given below to find the centos version.

# cat /etc/redhat-release


Dependency that is needed for memcached is libevent. First we will proceed with  libevent.
Steps for installation libevent.
 # cd /usr/local/src/

 # curl -O http://monkey.org/~provos/libevent-1.4.14b-stable.tar.gz

 # tar xzvf libevent-1.4.14b-stable.tar.gz 

 # cd libevent-1.4.14b-stable

 # ./configure --prefix=/usr/local/

 # make 

 # make  install

Next we need to  install memcached.

# cd /usr/local/src

# curl -O http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz

# tar -xvzf memcached-1.4.5.tar.gz

# cd memcached-1.4.5

# LDFLAGS='-Wl,--rpath /usr/local/lib' ./configure --prefix=/usr/local

# make

# make install

You can verify the memcache using the command

# memcached -u root -d

If there are no errors, memcache is successfully installed and is running.

# ps aux | grep memcached

Note: 

memcached: error while loading shared libraries: libevent-1.4.so.2: 
  cannot open shared object file: No such file or directory
  configure: error: libevent is required
  If it's already installed, specify its path using --with-libevent=/dir/

Install php-memcache

Please try the following steps
# wget http://pecl.php.net/get/memcache-3.0.3.tgz
# tar -xvzf memcache-3.0.3.tgz
# cd memcache-3.0.3
# phpize
#./configure
