"Backend login to the Core Config Manager failed"

[mindspring]

Hi there,
The customer above is getting an error when using the autodiscovery wizard. When we apply the configuration we get the error
"Backend login to the Core Config Manager failed"

I have attached the two files required to debug.

Can anyone assist please?

Tnx

Can you work through this section of the wiki and let us know how it goes?:

Yes thanks, I have done the above and attached the output of the two files

Have you, or one of your users changed the mysql database's login credentials? Either on the database itself, or in the interface? Have you instituted a ramdisk or offloaded your database recently?

[slansing]

Please remove the following files, then try to apply config:

Code: Select all

rm -f /usr/local/nagiosxi/scripts/nagiosql.*

I encountered this problem before.

after changing core config manager (CCM) password, I got this error.

Therefore, I re-changed the password to default which is "welcome"

Then, the problem has gone.

Did slansing's suggestion help? BTW, have you tried resetting the security credentials (Admin->Reset Security Credentials)?

The above post from Slansing ( rm -f /usr/local/nagiosxi/scripts/nagiosql.* ) didn't work for me

I also tried resetting Cred's and setting PW to welcome ... these didn't work either. I amd still getting;

Can you show us the "// db-specific connection information" section from the "/usr/local/nagiosxi/html/config.inc.php" file? Hide the sensitive info ("non-default" passwords, etc.).

Also check if you have database errors in the mysqld.log:

Code: Select all

tail -20 /var/log/mysqld.log
