開放連接埠:
代碼如下 |
複製代碼 |
[root@WX32 ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT |
儲存配置:
代碼如下 |
複製代碼 |
[root@WX32 ~]# service iptables save Saving firewall rules to /etc/sysconfig/iptables: [ OK ] |
重啟防火牆:
代碼如下 |
複製代碼 |
[root@WX32 ~]# service iptables restart Flushing firewall rules: [ OK ] Setting chains to policy ACCEPT: filter [ OK ] Unloading iptables modules: [ OK ] Applying iptables firewall rules: [ OK ] Loading additional iptables modules: ip_conntrack_netbios_n[ OK ] |
查看配置:
代碼如下 |
複製代碼 |
[root@WX32 ~]# service iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 |
連接埠查看方法:
代碼如下 |
複製代碼 |
[root@vcentos ~]# /etc/init.d/iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:80 2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 3 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0 |
補充:
查看CentOS防火牆資訊:/etc/init.d/iptables status
關閉CentOS防火牆服務:/etc/init.d/iptables stop
檢查是不是伺服器的80連接埠被防火牆堵了,可以通過命令:telnet server_ip 80 來測試。

1>.解決方案如下: /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT 2>.然後儲存: /etc/rc.d/init.d/iptables save 3>.重啟防火牆 /etc/init.d/iptables restart |
