防火墙设置
#设置规则
vim /etc/sysconfig/iptables
#如果限定某些机器能访问可如下设置：
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p udp -m udp --dport 11211 -j ACCEPT
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p tcp -m tcp --dport 11211 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 11211 -j DROP
-A INPUT -p udp -m udp --dport 11211 -j DROP
#重启iptables使得规则生效
service iptables restart
启动
/etc/init.d/memcached start
