#重启网络服务，则报错，启动失败 systemctl restart network #错误信息 Restarting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details. #按照提示输入 systemctl status network.service #显示错误 network.service: control process exited, code=exited status=1 Failed to start LSB: Bring up/down networking. Unit network.service entered failed state. network.service failed.通过查看资料，找到原因是和NetworkManager冲突，禁用即可
