This morning in 2017-08-04, I opened the virtual machine, using the remote tool Xshell to connect the virtual machine, I found that the connection is not up, and then I ifconfig, found that ens33, there is a local loopback, it appears that my network has a problem, and then I look at my network status, The following conditions were found:
[[Email protected] ~]# 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 .- ,-Geneva ,: -: toCST; 1min 44s ago Docs:Mans: Systemd-sysv-generator (8) Process:62726Execstop=/etc/rc.d/init.d/network Stop (code=exited, status=0/SUCCESS) Process:63183Execstart=/etc/rc.d/init.d/network start(code=exited, status=1/ FAILURE) theGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 network[63183]: Rtnetlink answers:file ExistsaugGeneva ,: -: toCT71 systemd[1]: Network.service:control process exited, code=exited status=1 theGeneva ,: -: toCT71 systemd[1]:Failed to start lsb:bring up/Down networking. theGeneva ,: -: toCT71 systemd[1]: Unit Network.service entered failed state. theGeneva ,: -: toCT71 systemd[1]: Network.service failed.
I found a number of answers to some degree, did not find the answer I can solve the problem, and then I do Google, on a blog to find the answer I need, do not know whether it will be targeted at everyone can, the method is to turn off network management, as follows:
Systemctl Stop NetworkManager
I have solved the problem after doing the above step, the answer that the blog gives has the following steps, I do not use:
systemctl Disable NetworkManager /etc/systemd/system/multi-user.target.wants/networkmanager.service. /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service. /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Then restart the network:
Systemctl Start Network.service
You can use the following:
