开放端口:
代码如下 | 复制代码 |
[root@WX32 ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT |
保存配置:
代码如下 | 复制代码 |
[root@WX32 ~]# service iptables save Saving firewall rules to /etc/sysconfig/iptables: [ OK ] |
重启防火墙:
代码如下 | 复制代码 |
[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:
代码如下 | 复制代码 |
[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 |
端口查看方法:
代码如下 | 复制代码 |
[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 |
补充:
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
检查是不是服务器的80端口被防火墙堵了,可以通过命令:telnet server_ip 80 来测试。
代码如下 | 复制代码 |
1>.解决方法如下: /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT 2>.然后保存: /etc/rc.d/init.d/iptables save 3>.重启防火墙 /etc/init.d/iptables restart |
