Login.php corrupt

Posted: Thu Nov 24, 2011 6:51 am

When I want to log in to Nagios XI it gives me a empty page where the log in screen was. This is after i connected to x.x.x.x and got the continue to Nagios XI screen.
When I tried to restart Nagios, the command line gave me a config error which after some research had to do with the services configuration. When I corrected this, Nagios started just fine, but I still couldnt't login. I can login to Nagios Core, but I need the config options from Nagios XI.

Some more research led to the discovery that my login.php file was probably corrupted because all the other PHP files are just code (I can't read PHP yet) but the login.php is all just garbled letters and numbers. Is there a place where I can download a new login.php file or do I have to start over from scratch (which isn't a problem)?

This problem occured when I installed the X Window system with KDE on the CentOS machine. I use the virtual appliance with CentOS 6.

Thanks for helping.

-Edit-
I researched some more and found the login.php file of another test version of Nagios XI. This file has the same crazy code which I don't understand. I still think there is something wrong with this file because I haven't changed any of the PHP files.
To make it easier for you guys I include the code here.

I fixed the problem.

When you asked to send the logfile (which I didn't find before yout suggestion, thanks) I looked at the logfile and saw that the problem was the mysql.sock file.
It didn't exsist so I tried to find a solution to this.

This was the instrustion to fix this:

1) Stop MySQL server,
2) Type safe_mysqld --socket=/var/lib/mysql/mysql.sock
3) ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
4) Start MySQL . ( Recommended )

I als found out that there (strangely) no MySQL service installed on the server. With "yum groupinstall mysql" I installed the MySQL server role and then stopped the service.
The second step didn't work, so went on with step 3 like this:

ln -s /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock

After this, I started the MySQL service again and Nagios XI login worked. The sad thing is the trial licence has expired, so I need to buy a licence.

Thanks for looking into this, and I hope this post is usefull for other people.
