问题描述：
在Centos服务器上装好Redis缓存服务后，其他机器访问不了，提示连接超时。,郁闷,在网上找到解决方案：
/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT
/sbin/iptables -I INPUT -p tcp --dport 6380 -j ACCEPT
然后保存：
/etc/rc.d/init.d/iptables save
这样重启计算机后,CentOS防火墙默认已经开放了6379和6380端口。
这里应该也可以不重启计算机：
/etc/init.d/iptables restart
查看CentOS防火墙信息：
/etc/init.d/iptables status
关闭CentOS防火墙服务：
/etc/init.d/iptables stop
永久关闭：
chkconfig –level 35 iptables off
