注意事项：memceached服务器必须要在LNMP环境下使用，这个大家要注意了。
首先把（ memceached-package.zip ）软件包拖到系统的桌面，然后减压。
[root@localhost 桌面]# ls memceached-package.zip
memceached-package.zip
[root@localhost 桌面]# unzip memceached-package.zip
切换到减压目录并且查看这个目录下有哪些软件包：
[root@localhost 桌面]# cd memceached-package
[root@localhost memceached-package]# ls
libevent-2.0.15-stable.tar.gz memcached-1.4.5.tar.gz
减压（libevent-2.0.15-stable.tar.gz）这个软件包，并且切换到减压后的这个软件包的目录、
[root@localhost memceached-package]# tar zxf libevent-2.0.15-stable.tar.gz
[root@localhost memceached-package]# ls
libevent-2.0.15-stable libevent-2.0.15-stable.tar.gz memcached-1.4.5.tar.gz
[root@localhost memceached-package]# cd libevent-2.0.15-stable
现在开始涉足环境和安装，
[root@localhost libevent-2.0.15-stable]# ./configure
[root@localhost libevent-2.0.15-stable]# make
[root@localhost libevent-2.0.15-stable]# make install
现在回到（memceached-package）目录并且查看这个目录下的软件包：
[root@localhost memceached-package]# cd /root/桌面/memceached-package
[root@localhost memceached-package]# ls
libevent-2.0.15-stable libevent-2.0.15-stable.tar.gz memcached-1.4.5.tar.gz
现在减压这个软件包：
[root@localhost memceached-package]# tar zxf memcached-1.4.5.tar.gz
[root@localhost memceached-package]# ls
libevent-2.0.15-stable libevent-2.0.15-stable.tar.gz memcached-1.4.5 memcached-1.4.5.tar.gz
[root@localhost memceached-package]# cd memcached-1.4.5
[root@localhost memcached-1.4.5]# ./configure
[root@localhost memcached-1.4.5]# make
[root@localhost memcached-1.4.5]# make install
启动memcahced 服务：
Libevent.conf这个文件是没有的我们新建，并且要跟新一下。
[root@localhost memcached-1.4.5]# echo "/usr/local/lib/" > /etc/ld.so.conf.d/libevent.conf
[root@localhost memcached-1.4.5]# ldconfig -v
现在就启动服务：
[root@localhost ~]# /usr/local/bin/memcached -p 11211 -l 192.168.1.2 -m 100MB -n 10 -f 2 -u root -vvv -d
[root@localhost ~]# slab class 1: chunk size 64 perslab 16384

在客户端上使用（telnet）来测试：
如果没有这个命令就要安装这个命令的软件包了。
[root@localhost ~]# yum -y install telnet
[root@localhost ~]# telnet 192.168.1.2 11211
Trying 192.168.1.2...
Connected to 192.168.1.2.
Escape character is ‘^]‘.
set name 0 180 3 #读数据
jim
STORED
get name #取数据
VALUE name 0 3
jim
END
Quit #退出
Connection closed by foreign host.
[root@localhost ~]#
这个是是武器上的变化：
[root@localhost ~]# <33 new auto-negotiating client connection

33: going from conn_waiting to conn_read
33: going from conn_read to conn_parse_cmd
