【已解决】虚拟机装好centos后直接装lnmp可以用，重启虚拟机就打不开网页了
centos安装在虚拟机内，使用桥接网卡网络模式，宿主机可ssh到centos虚拟机上，代表宿主机和虚拟机是连通的。虚拟机刚装好系统就进去装Lnmp了，装好lnmp后是可以用的，虚拟机重启后就访问不到网页了。centos 7 minimal不带iptables，所以排除了iptables阻挡80端口的可能性。
虚拟机重启几次，lnmp也restart几次，问题依旧。
真找不出问题在哪了。。。只好厚颜来请教军哥了。
以下都是ssh到虚拟机后执行的，ip确认是正确的# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN

这三种文件都无法访问 原来是centos 7 用firewall 代替了 iptables，
firewall-cmd --zone=public --add-port=80/tcp --permanent
加上80端口就可以了
