1、首先要分析一下安装 memcache需要依赖组件libevent，rpm -qa|grep libevent 检查有没有安装 libevent
2、首先要先安装libevent，yum install libevent执行命令安装
3、安装完成以后安装Memcached，下载Memcached执行命令wget hhttp://memcached.org/files/memcached-1.5.0.tar.gz
4、解压memcached-1.5.0.tar.gz，
5、configure时需要指定libevent的安装路径，./configure -with-libevent=/usr/libevent/ -prefix=/usr/local/memcached
6、make&make install 编译和安装
7、./memcached -h 查看版本
