产看Apache 状态

您可以通过以下命令来查看Apache的状态：

sudo systemctl status apache2

如果Apache正在运行，您将看到类似以下内容的输出：

● apache2.service - The Apache HTTP Server
   Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
  Drop-In: /lib/systemd/system/apache2.service.d
           └─apache2-systemd.conf

           ├─1235 /usr/sbin/apache2 -k start
           └─1236 /usr/sbin/apache2 -k start

如果Apache未运行，您将看到类似以下内容的输出：

  Drop-In: /lib/systemd/system/apache2.service.d
           └─apache2-systemd.conf
