虚拟机连接xshell报错 Could not connect to 'hadoop102' (port 22): Connection failed.

在hadoop102中打开终端
ping一下百度
ping www.daidu.com
输入命令ifconfig
出现下图这样的情况 发现没有ens33

重启network
service network restart
报错结尾出现红字Failure
解决方法：关闭NetworkManager
systemctl stop NetworkManager
systemctl disable NetworkManager
#重启
systemctl start network.service
不报错结尾是绿字OK
