CentOS6 开放端口（iptables: Applying

[root@localhost~]#iptables -N RH-Firewall-1-INPUT

[root@localhost~]# service iptables save

编辑/etc/sysconfig/iptables，添加

-ARH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3690 -j ACCEPT

[root@localhost~]#vim /etc/sysconfig/iptables

再重新启动3690端口

[root@localhost~]# service iptables restart
