centOS 7一个解决“network.service: control process exited, code=exited status=1”方法

 

　　今天早上2017-08-04，我打开虚拟机，使用远程工具xshell对虚拟机进行连接，我发现连接不上去，然后我ifconfig，发现找不到ens33了，就剩一个本地回环，看来是我的网络出现了问题，然后我查看我的网络状态，发现了如下情况：

[root@CT71 ~]# systemctl status network.service 
● network.service - LSB: Bring up/down networking
   Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)
   Active: failed (Result: exit-code) since Fri 2017-08-04 08:20:31 CST; 1min 44s ago
     Docs: man:systemd-sysv-generator(8)

我在某度上找了好几个答案，都没有找到我能解决问题的答案，然后我进行Google，在一个博客上找到了我需要的答案，不知道是不是会针对于大家都可以，方法是关闭网络管理，如下：

systemctl stop NetworkManager

我在执行上面一步后就已经解决了问题，那个博客给出的答案还有下面的步骤，我没有用：

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.

然后重启网络：

systemctl start network.service

可以使用了：
