Ubuntu memcached Installation and Java memcached using demo

If Libevent is not installed, first install

(1) Installation libevent

(Apt-get install: Libevent seems not to have been recognized)

Download http://www.monkey.org/~provos/libevent-2.0.12-stable.tar.gz

Libevent-2.0.12-stable$configure

Libevent-2.0.12-stable$make

Libevent-2.0.12-stable$sudo make Install

(2) Installation memcached

Download Installation memcached1.4.5

Http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz

Memcached-1.4.5$./configure

Memcached-1.4.5$make

Memcached-1.4.5$sudo make Install

If startup fails and libevent is not found, connect

/usr/lib$ sudo ln-s/usr/local/lib/libevent-2.0.so.5 libevent-2.0.so.5

(3) Start

$memcached-D-m 128-p 11111-u Root

Here you need to explain the startup parameters for the memcached service:
-P Listening Port
The IP address of the-l connection, the default is native
-D Start memcached service
-D Restart Restart memcached service
-D Stop|shutdown shut down the running memcached service
-D Install installation memcached service
-d Uninstall Uninstall memcached service
-U Run as (only valid when run as root)
-m maximum memory usage, in MB. Default 64MB
-Returns an error when M memory is exhausted instead of deleting the item
-C Maximum Simultaneous connection number, default is 1024
-F Block size growth factor, default is 1.25-n minimum allocation space, key+value+flags default is 48
-H Display Help 2 install Memcache client
