nginx开启后主机无法访问虚拟机的nginx解决方案

如果IP可以通的话 一般是防火墙引起

方法1、cat /etc/sysconfig/iptables

# Generated by iptables-save v1.4.7 on Fri Nov  ::
*filter
:INPUT ACCEPT [:]
:FORWARD ACCEPT [:]
:OUTPUT ACCEPT [:]
-A INPUT -p tcp -m tcp --dport  -j ACCEPT
-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  -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

加-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT

方法2、

[root@localhost ]# /sbin/iptables -I INPUT -p tcp --dport  -j ACCEPT
[root@localhost ]# /etc/init.d/iptables save
[root@localhost ]# /etc/init.d/iptables restart
