Database Connect Error: Centos 6 / Apache 2.4 / Postgres 9.4 / Django 1.9 / mod_wsgi 3.5 / python 2.7

Question

I am trying to get my website up and running. Everything seems to work fine, but when I go to a page with a database write - I get this:

[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

This line shows that a user "leechprotest" cannot connect:

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

However I don't have a user called leechprotect. leechportect is a default user on MySQL (im guessing), because MySQL is installed as the default database on my dedicated server.

My Django settings.py file:

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

I already know my database and entire site works on my test server at home. I think it might be interference with MySQL and PostgreSQL.

Any help much appreciated.

EDIT (After disabling leech protection):

EDIT 2:

I found that Apache comes preconfigured on cPanel with a rewrite function:

These lines are in the httpd.conf file:

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

I tried to comment out these lines, but cPanel just regenerates the default file. I looked how to edit and I found:

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

From what I see, anyting written outside the <VirtualHost></VirtualHost> tag with be permanently saved when running the above command.

this got rid of the Database error problem. But I still get a 500 server error. And all other error log messages are the same.

Answer 1

MySQL and PostgreSQL both do not come along with a user called 'leechprotect'. But a google search points out, that this username is related to cPanel - might be worth reading that to understand whats going on. Afterwards you might consider deactivating it for you project directory.
