Ubuntu 16.04は低下モードで実行されています
最近、14.04から16.04に更新しました。サーバーにApache2がありますが、最近、これに気付きました。
fmf@Kodi:~$ systemctl is-system-running
degraded
fmf@Kodi:~$
だから私は少し掘ります：
fmf@Kodi:~$ systemctl --state=failed
UNIT LOAD ACTIVE SUB DESCRIPTION
● Apache2.service loaded failed failed LSB: Apache2 web server
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'.
fmf@Kodi:~$
それからもう少し掘ります：
fmf@Kodi:~$ systemctl status -l Apache2.service
● Apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/Apache2; bad; vendor preset: enabled)
Drop-In: /lib/systemd/system/Apache2.service.d
└─Apache2-systemd.conf
Active: failed (Result: exit-code) since Wed 2016-08-03 14:57:11 CEST; 7min ago

奇妙なことは、サーバー上のWebページに接続しようとすると、それが表示されることです。そのエラーはどこから来ますか？ Apache2のログを確認しようとしましたが、奇妙なものは見つかりませんでした。
たぶんこの助け：
fmf@Kodi:~$ netstat -antp | grep 80
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

助けてください？
あなたも試してみてください：
