CentOS off Firewall Open iptables

Today want to try to start the boot Nginx, and then in the Iptables opened a port, set up a boot iptables, found that always can not be effective, after query, find a way to solve the problem, That is to close the firewall open iptables (Note: refer to http://www.cnblogs.com/xuezhigu/p/6652835.html).

First make sure you install the Iptables service and how to install it. With Yum:yum install iptables, turn on boot: chkconfig iptables on, turn on boot: chkconfig iptable Enable, close Firewall service: Systemctl Stop Fir Ewalld.service, turn off boot

: Systemctl disable Firewalld.service, so it's done.
