memcached经典入门教程

单机部署：

yum安装与启动

通过yum 安装是相对简单的安装方式

yum install memcached -y
vim /etc/sysconfig/memcached
PORT="11211" #监听端口
USER="memcached" #启动用户
MAXCONN="1024" #最大连接数
CACHESIZE="1024" #最大使用内存
OPTIONS="" #其他选项

python操作memcache

#!/usr/bin/env python
#coding:utf-8

import memcache
m = memcache.Client(['172.18.200.106:11211'], debug=True)
for i in range(100):
    m.set("key%d" % i,"v%d" % i)
    ret = m.get('key%d' % i)
    print ret

编译安装

[root@centos7 ~]#yum –y install gcc  libevent-devel 
[root@centos7 ~]#wget http://memcached.org/files/memcached-1.5.22.tar.gz
