linux打开80端口
天客户那边有台服务器同一个局域网中都无法访问，排除lamp环境问题，发现时服务器中的防火墙没有开启80端口。于是去网上搜索了一下，在脚本之家看到一种添加代码的方法
| 代码如下 | 复制代码 |
|
vi /etc/sysconfig/iptables -A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT（允许80端口通过防火墙） |
|
按照这种方法测试，发现重启防火墙的时候，回报这两行错误。
[root@localhost ~]# /etc/init.d/iptables restart
iptables：清除防火墙规则： [确定]
iptables：将链设置为政策 ACCEPT：filter [确定]
iptables：正在卸载模块： [确定]
iptables：应用防火墙规则：Bad argument `–-state'
Error occurred at line: 11
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
[失败]
发现这种方法并不好使，于是尝试另外一种，通过命令去添加端口的方法。
| 代码如下 | 复制代码 |
|
[root@centos httpd]# /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT [root@centos httpd]# /etc/rc.d/init.d/iptables save [root@centos httpd]# /etc/init.d/iptables restart |
|
这样就搞定了，查看效果
| 代码如下 | 复制代码 |
|
[root@centos httpd]# /etc/init.d/iptables status |
|
Linux下启动apache报错：80端口已占用解决办法
