centos7 jexus在vmware下能访问，主机访问不了解决方案

能PING通，访问不了web，先在CMD测试telnet ip 80看看是否是防火墙的问题.

修改防火墙，打开指定端口

1 安装iptables

[[email protected] ~]# yum install iptables-services

设置防火墙规则 (增加80端口)

[[email protected] ~]# vim /etc/sysconfig/iptables

打开文件，增加80端口那一行

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

:wq #保存退出

2 默认firewall作为防火墙的设置

#禁止firewall开机启动

[[email protected] ~]# systemctl disable firewalld.service

#设置防火墙开机启动

[[email protected] ~]# systemctl enable iptables.service

#停止firewall

[[email protected] ~]# systemctl stop firewalld.service

#重启防火墙使配置生效

[[email protected] ~]# systemctl restart iptables.service (必须重启)

3 查看当前系统打开的端口

[[email protected] ~]# netstat -lntp
