一、memcache说明
memcached是一套开源分布式的高速缓存系统，memcached缺乏认证以及安全管制，这代表应该将memcached服务器放置在防火墙之后，以确保安全。
系统环境：CentOS6.8_x64
二、安装
1、安装gcc
yum install -y wget gcc
2、下载安装源码libevent

#tar zxvf libevent-2.0.21-stable.tar.gz
#cd libevent-2.0.21-stable
#./configure --prefix=/usr/local/libevent
#make && make install

#wget http://www.memcached.org/files/memcached-1.4.24.tar.gz #如找不到请下载最新版本
#tar zxvf memcached-1.4.24.tar.gz
#cd memcached-1.4.24
#./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
#make && make install
#ln -s /usr/local/memcached/bin/memcached /usr/local/bin/

三、编写服务脚本
1、脚本内容如下：
cat /etc/init.d/memcached

2、说明：
daemon --pidfile=${pidfile} /usr/local/bin/memcached -u daemon -d -m 512 -l 10.1.0.6 -c 4096 -p 11211
-m:指定memcache缓存内存大小
-l:指定memcache的侦听地址一般内网
-c: 最大并发连接数。
-p:侦听端口
3、添加到开机自启服务并启动服务
