CentOS7 network.service loaded failed 处理技巧
某一日，用systemctl --failed查看到如下错误信息，但实际上网络是OK的，真奇怪：1

# systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
network.service loaded failed failed LSB: Bring up /down networking
LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type .
1 loaded units listed. Pass --all to see loaded but inactive units , too.
To show all installed unit files use 'systemctl list-unit-files' .
执行此命令来解决这个问题：
1
# systemctl enable NetworkManager-wait-online.service
重启后再次用systemctl --failed查看，问题消失：
1
2
3
# systemctl --failed
0 loaded units listed. Pass --all to see loaded but inactive units , too.
To show all installed unit files use 'systemctl list-unit-files' .
解决问题的关键跟/usr/lib/systemd/system/NetworkManager-wait-online.service这个文档有关，其内容如下：
Description=Network Manager Wait Online
Requisite=NetworkManager.service
After=NetworkManager.service
Wants=network.target
Before=network.target network-online.target
Type=oneshot
ExecStart=/usr/bin/nm-online -q --timeout=30
WantedBy=multi-user.target
有兴趣的同学不妨研究一下这个文档就能明了！！
最后sudo service network restart 解决
