前几天是node3连不上，今天早上写作业发现node2又连不上了
]$ systemctl status network.service ● network.service - LSB: Bring up/down networking Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled) Active: active (exited) since 二 2023-11-14 08:11:26 CST; 6min ago Docs: man:systemd-sysv-generator(8) Process: 818 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=0/SUCCESS) Tasks: 0
输入以上命令以后吧又发现vmware里面正常，然后我就去找hosts文件了，发现不知道什么时候被清空了，然后我又把各个配置补上去了，就正常了
别忘了写上虚拟机ip
ifconfig可以查看当前虚拟机ip
比如:
]$ ifconfig
