Memcache is a high-performance memory object caching system intended to speed up dynamic web applications by reducing database load on the server. Memcache is fast it uses libevent, which provides a mechanism to execute a callback function when a specific event occurs on a file descriptor, to scale to any number of open connections. On a modern Linux  system memcached utilizes epoll, is completely non-blocking for network I/O, ensures memory never gets fragmented, and uses its own slab allocator and hash table to achieve 0(1) virtual memory allocation.

#curl -O http://monkey.org/~provos/libevent-1.4.9-stable.tar.gz

#tar -xzvf libevent-1.4.9-stable.tar.gz

#cd libevent*

#./configure

#make

#make install

Now let’s download the newest Memcached source

#curl -O http://www.danga.com/memcached/dist/memcached-1.3.0.tar.gz

#tar zxf memcached-1.3.0.tar.gz

#cd memcached-1.3.0

#./configure

#make

#make install

Then add /usr/local/lib to LD_LIBRARY_PATH in your .bash_profile

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

Add the below link in php.ini of the server

extension=memcache.so

Now restart Apache:

Service httpd restart

Once it sucussfully install you can create phpinfo() on your webserver should now confirm that memcache is installed.
