Linux配置防火墙端口 8080端口

1、查看防火墙状态，哪些端口开放了

/etc/init.d/iptables status

2、配置防火墙

vi /etc/sysconfig/iptables   ######################################  # Firewall configuration written by system-config-firewall  # Manual customization of this file is not recommended.  *filter  :INPUT ACCEPT [0:0]  :FORWARD ACCEPT [0:0]  :OUTPUT ACCEPT [0:0]  -A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT  -A INPUT -p icmp -j ACCEPT  -A INPUT -i lo -j ACCEPT  -A INPUT -m state –state NEW -m tcp -p tcp –dport 22 -j ACCEPT  -A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT  -A INPUT -m state –state NEW -m tcp -p tcp –dport 8080 -j ACCEPT  -A INPUT -j REJECT –reject-with icmp-host-prohibited  -A FORWARD -j REJECT –reject-with icmp-host-prohibited  COMMIT  #####################################

#最后重启防火墙使配置生效

/etc/init.d/iptables restart
