CentOS7设置静态ip后,无法ping通外网问题

*  VM和CentOS7安装参考: [VM15安装][VM15]、[CentOS7安装][CentOS7]
 *  当我们安装好CentOS7后, 要分配一个ip给系统, 进入root权限, 使用`dhclient`动态分配一个ip地址给linux系统; 但是这样只是动态的分配一个, 下次启动后该ip就不可用了, 此时就需要将这个ip静态设置该这个系统;

设置静态ip, 首先进入`vi /etc/sysconfig/network-scripts/ifcfg-ens33` 编辑该文件, 修改为如下:

如果网关地址配置错误, 就会导致该centos系统访问外网不通;

`注意:` 修改完上面文件后, 要重启网络, 命令`systemctl restart network.service`

此时就可以Ping通外网地址
