centOS 7一個解決「network.service: control process exited, code=exited status=1」方法

 

　　今天早上2017-08-04，我打開虛擬機，使用遠程工具xshell對虛擬機進行鏈接，我發現鏈接不上去，而後我ifconfig，發現找不到ens33了，就剩一個本地迴環，看來是個人網絡出現了問題，而後我查看個人網絡狀態，發現了以下狀況：

[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) Process: 62726 ExecStop=/etc/rc.d/init.d/network stop (code=exited, status=0/SUCCESS) Process: 63183 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE) Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 network[63183]: RTNETLINK answers: File exists Aug 04 08:20:31 CT71 systemd[1]: network.service: control process exited, code=exited status=1 Aug 04 08:20:31 CT71 systemd[1]: Failed to start LSB: Bring up/down networking. Aug 04 08:20:31 CT71 systemd[1]: Unit network.service entered failed state. Aug 04 08:20:31 CT71 systemd[1]: network.service failed.

我在某度上找了好幾個答案，都沒有找到我能解決問題的答案，而後我進行Google，在一個博客上找到了我須要的答案，不知道是否是會針對於你們均可以，方法是關閉網絡管理，以下：

systemctl stop NetworkManager

我在執行上面一步後就已經解決了問題，那個博客給出的答案還有下面的步驟，我沒有用：

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.

而後重啓網絡：

systemctl start network.service

能夠使用了：
