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：
[[email protected] media]# 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：
[root@F1A-SWPE ~]# systemctl enable NetworkManager-wait-online.service
重启后再次用systemctl --failed查看，问题消失：
[[email protected] ~]# 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：
[Unit]
Description=Network Manager Wait Online
Requisite=NetworkManager.service
After=NetworkManager.service
Wants=network.target
Before=network.target network-online.target
[Service]
Type=oneshot
ExecStart=/usr/bin/nm-online -q --timeout=30
[Install]
WantedBy=multi-user.target
有兴趣的同学不妨研究一下这个文档就能明了！！
