环境变量的Apache错误（Ubuntu）

Question

我的操作系统是Ubuntu 12.04，我分别安装了Apache，Php和Mysql。我从来没有遇到过问题，但是在Ubuntu更新之后，当我尝试访问Web服务器上的php文件时，总是会收到“ 404 Not Found”错误。

当我在控制台上写“ apache2 -S”时，得到以下信息：

AH00526: Syntax error on line 75 of /etc/apache2/apache2.conf:
Invalid Mutex directory in argument file:${APACHE_LOCK_DIR} 

谁能帮我吗？

通过阅读此错误页面，我推测所有这些都是环境变量，在运行apache2之前需要将其导出。显然，当您将它们作为“ service apache2 start”之类的服务运行时，这些文件会自动从/ ​​etc / apache2 / envvars中加载。另一个选择是使用apache2ctl启动它。
