Apache没有启动
所以我尝试使用以下命令启动我的apache2服务器…
sudo service apache2 start 但后来我收到此错误消息……
Job for apache2.service failed. See "systemctl status apache2.service" and "journalctl -xe" for details.
所以，当我尝试看到systemctl时，我得到了这个……

我的浏览器上的http：// localhost /也给了我一个错误，这意味着apache没有运行。
我这样做的时候……
sudo restart apache2
我收到这个错误……
restart: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
有人请帮忙。
我认为由于某种原因你删除了envvars配置文件
Jul 06 10:34:49 archisman-HP-ProBook-440-G2 apache2[8899]: /etc/init.d/apache2: 64: .: Can't open /etc/apache2/envvars Jul 06 10:34:49 archisman-HP-ProBook-440-G2 apache2[8899]: /etc/init.d/apache2: 76: .: Can't open /etc/apache2/envvars
所以你必须创建它并从这里粘贴内容（此文件的默认内容）
sudo touch /etc/apache2/envvars sudo nano /etc/apache2/envvars
然后像往常一样重启apache服务
sudo service apache2 restart
我有同样的问题，我出于某种原因在apache.conf file进行了更改，这导致我和你一样的错误。
我重新安装了Apache服务器，现在一切正常。
使用以下命令：
-
卸载Apache：
sudo apt-get remove apache2* -
安装Apache
sudo apt-get install apache2 -
重启服务器
sudo service apache2 restart
