数据库连接错误：Centos 6 / Apache 2.4 / Postgres 9.4 / Django 1.9 / mod_wsgi 3.5 / python 2.7

Question

我正在努力让我的网站启动并运行。一切似乎都运行良好，但是当我转到带有数据库写入的页面时 - 我得到了这个：

[Wed Oct 19 09:53:12.319824 2016] [mpm_prefork:notice] [pid 12411] AH00173: SIGHUP received.  Attempting to restart

[Wed Oct 19 09:53:17.637487 2016] [mpm_prefork:notice] [pid 12411] AH00169: caught SIGTERM, shutting down

此行显示用户“leechprotest”无法连接：

(XID fsf92m) Database Connect Error: Access denied for user 'leechprotect'@'localhost' (using password: YES)

但是，我没有名为 leechprotect 的用户。 leechportect 是 MySQL 的默认用户（我猜），因为 MySQL 作为默认数据库安装在我的专用服务器上。

我的 Django settings.py 文件：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'prelaunch_db',
        'USER': 'postgres_user',
        'PASSWORD': 'XXXXXXXXXXXXXXX',
        'HOST': 'localhost',
        'PORT': '',
    }
}

我已经知道我的数据库和整个站点在我家的测试服务器上运行。我认为这可能是对 MySQL 和 PostgreSQL 的干扰。

非常感谢任何帮助。

编辑 2：

我发现 Apache 在 cPanel 上预配置了一个重写功能：

这些行在 httpd.conf 文件中：

RewriteEngine on
RewriteMap LeechProtect prg:/usr/local/cpanel/bin/leechprotect
Mutex file:/usr/local/apache/logs rewrite-map

我试图注释掉这些行，但 cPanel 只是重新生成默认文件。我查看了如何编辑并发现：

[root@sXXX-XXX-XXX-XXX]# /usr/local/cpanel/bin/apache_conf_distiller --update

据我所知，<VirtualHost></VirtualHost> 标签之外的任何内容在运行上述命令时都会被永久保存。

这摆脱了数据库错误问题。但我仍然收到 500 服务器错误。并且所有其他错误日志消息都是一样的。

MySQL 和 PostgreSQL 都没有附带名为“leechprotect”的用户。但是谷歌搜索指出，这个用户名is related to cPanel - 可能值得一读以了解发生了什么。之后您可能会考虑为您的项目目录停用它。
