Failed to start LSB: Bring up/down networking.

由于我的虚拟机是从别的机器拷贝过来的，导入新机器后，没有问题，第二天就网络连接不上了，就出现下面的错误

[root@centos ~]# /etc/init.d/network restart
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.

百度了一大堆，都说是拷过来的时候mac地址的问题。

下面就提供了我解决问题的方法：

#关闭系统自带的NetworkManager这个管理套件就可以解决。
[root@centos ~]# systemctl stop NetworkManager
[root@centos ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
[root@centos ~]# 
#重启网络
[root@centos ~]# /etc/init.d/network restart
Restarting network (via systemctl):                        [  OK  ]
