systemd[1]：无法启动LSB:Apache2 web服务器

我有一个ApacheWeb（版本2.4.10）服务器运行在Debian8（Jessie）上。它主要用作SVN存储库服务器。 几周后，它一直运行良好，当我试图从Web浏览器列出SVN回购协议时，突然出现了一个内部错误，如下所示：

正如您所看到的，身份验证仍然可以正常工作

我运行了以下两个命令： systemctl状态apache2.service 和 journalctl-xn

但这对我没什么帮助，也许我错过了什么？ 我没有修改最近与Apache相关的任何配置文件（甚至没有修改任何其他配置文件）：既没有修改主Apache conf文件，也没有修改任何vHost conf文件。 我尝试重新启动Apache，它确实重新启动了，但Web服务器仍然遇到内部错误

这可能来自mod_wsgi正在运行的Python版本，它与mod_wsgi显然期望的不同吗？

尝试两个命令：

sudo apt-get purge apache2 

sudo apt-get install apache2

---

之后，使用systemctl status apache2检查apache的状态

这些命令解决了我的问题：

sudo apt-get remove apache2 

sudo apt-get install apache2

注意：如果您使用

purge

作为另一个答案，您应该再次设置所有Apache配置，但当您使用

remove

时，它只会删除Apache的核心，安装后您不需要更多
