php - HHVM/FastCGI/Proxy 安装毁了我的 apache？

Question

我有一台安装了 apache2 和 php5 的 ubuntu 14.04 笔记本电脑。他们都运作良好。昨天有空，试了一下安装nginx和hhvm。我按照互联网上的一些教程并设法安装它们。但是当我需要再次使用 apache 时，它​​不起作用。实际上当我打开 http://localhost ，它仍然显示“Apache2 Ubuntu 默认页面”页面，但它无法处理任何 php 文件，即使是具有 phpinfo() 函数的页面。我记得在安装 hhvm 之后，我执行了这个:

sudo /usr/share/hhvm/install_fastcgi.sh

这是输出:

我怀疑那条线毁了我的 apache。我不知道如何恢复它。有什么办法吗？我不想使用 fastcgi 或任何代理，我想停用/删除它们。
处理任何 php 文件时，我的浏览器上出现此错误“内部服务器错误”。从 apache 错误日志中，我得到了这个:

[Wed Mar 02 15:12:13.519428 2016] [proxy:error] [pid 20485] (111)Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:9000 (*) failed
[Wed Mar 02 15:12:13.519509 2016] [proxy_fcgi:error] [pid 20485] [client 127.0.0.1:54656] AH01079: failed to make connection to backend: 127.0.0.1 

然后我禁用 proxy_fcgi

sudo a2dismod proxy_fcgi

现在我在 apache 错误日志中得到了这个错误:

[Wed Mar 02 15:44:41.946487 2016] [proxy:warn] [pid 21422] [client 127.0.0.1:55563] AH01144: No protocol handler was valid for the URL /info.php. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule. 

我不知道如何解决这个错误。

从此链接:https://github.com/facebook/hhvm/issues/3472 ，罪魁祸首是这个文件:

/etc/apache2/mods-enabled/hhvm_proxy_fcgi.conf.

因为我没有时间玩更多，快速的解决方案就是重命名/删除文件。现在我的 Apache 服务器又开始工作了。
