1.安装libevent
yum install libevent.x86_ libevent-devel.x86_
没有libevent编译memcached为出错

checking for libevent directory... configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/
 If it's already installed, specify its path using --with-libevent=/dir/

2.安装memcached

wget http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
tar zxvf memcached-1.4.15.tar.gz
cd memcached-1.4.15
./configure --prefix=/opt/memcached-1.4.15
make
make install
ln -s /opt/memcached-1.4.15 /opt/memcached

3.配置文件
vi /opt/memcached/my.conf

PORT="11200"
IP="192.168.0.40"
USER="root"
MAXCONN="1524"
CACHESIZE="3000"
OPTIONS=""
#memcached

4.启动/关闭脚本
vi /etc/init.d/memcached

#!/bin/bash
#
# Save me to /etc/init.d/memcached
# And add me to system start
# chmod +x memcached
# chkconfig --add memcached
# chkconfig --level 35 memcached on

exit $RETVAL

5.添加iptables 充许192.168.0.0/24访问

iptables -A INPUT -s 192.168.0.0/255.255.255.0 -p tcp -m tcp --dport 11200 -j ACCEPT

6.启动
/etc/init.d/memcached start

7.web 管理界面
