yum clean all  
yum -y update  
yum -y install memcached

2.Memcached 运行

memcached -h  
  
//查看考号修改配置  
vim /etc/sysconfig/memcached  
内容如下：  
PORT=”11211″  
USER=”memcached”  
MAXCONN=”1024″  
CACHESIZE=”64″  
OPTIONS=”"  
  
可以修改端口，用户和最大内存，缓存大小  
//重启，启动，开机启动，状态，关闭  
systemctl restart memcached  
systemctl start memcached  
systemctl enable memcached  
systemctl status memcached  
systemctl stop memcached

3.扩展一下，安装PHP-memcache扩展，防火墙放开11211端口

yum -y install php-pecl-memcache  
如果是PHP56版本的应该运行  
yum -y install php56w-pecl-memcache  
防火墙放开11211  
firewall-cmd --permanent --zone=public --add-port=11211/tcp  
检查端口是否开放

echo stats | nc memcache\_host\_name\_or\_ip 11211
