systemd 沒有註意到 apache 啟動

我的 debian-system 已經感染了 systemd-virus…

當我發出“service apache2 start”命令啟動 apache 時，它認為它失敗了，但 apache 執行得很好。所以“service apache2 stop”什麼都不做，因為系統認為apache沒有啟動。要停止 apache，我必鬚髮出“killall apache2”

# service apache2 start
Job for apache2.service failed. See 'systemctl status apache2.service' 
  and 'journalctl -xn' for details.


# systemctl status apache2.service 
â apache2.service - LSB: Apache2 web server

Jun 09 15:49:43  systemd[1]: Unit apache2.service entered failed state.

系統是debian 8.5；通過多個版本升級。

為什麼“系統”認為它失敗了，當 apache 啟動就好了？

更新 /etc/init.d/apache2 在以下位置查找 pidfile

/var/run/apache2/apache2.pid

，但文件實際上位於

/var/run/apache2.pid

，即少一個子目錄。

pidfile 在一個意想不到的地方。編輯

/etc/apache2/envvars

線

導出 APACHE_PID_FILE=/var/run/apache2$SUFFIX.pid

使“服務 apache2 啟動/停止”工作
