搭建Memceached服务器
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。
# ls memceached-package.zip
memceached-package.zip
# 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：
# cd 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、
# tarzxf libevent-2.0.15-stable.tar.gz
# ls
libevent-2.0.15-stable libevent-2.0.15-stable.tar.gz memcached-1.4.5.tar.gz
# cdlibevent-2.0.15-stable
现在开始涉足环境和安装，
# ./configure
# make
# makeinstall
现在回到（memceached-package）目录并且查看这个目录下的软件包：
# cd /root/桌面/memceached-package
# ls
libevent-2.0.15-stablelibevent-2.0.15-stable.tar.gzmemcached-1.4.5.tar.gz
现在减压这个软件包：
# tarzxfmemcached-1.4.5.tar.gz
# ls
libevent-2.0.15-stablelibevent-2.0.15-stable.tar.gzmemcached-1.4.5memcached-1.4.5.tar.gz
# cd memcached-1.4.5
#./configure
#make
#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。
# echo"/usr/local/lib/" >/etc/ld.so.conf.d/libevent.conf
# ldconfig -v
现在就启动服务：
# /usr/local/bin/memcached-p11211 -l 192.168.1.2 -m 100MB -n 10 -f 2 -uroot -vvv-d

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。
#yum -yinstall telnet
#telnet192.168.1.2 11211
Trying 192.168.1.2...
