Nagios is not able to be logged in from GUI

[amit.ahuja]

Hi,

We are currently having trouble login to Nagios from GUI. We used the username and password, which were correct for sure, and clicked the login button. Then, the page was refreshed but sent us back to the login page again. It seems clicking on the login button just refresh the page without actually login.

Thanks in advace

Can you log in to core?

http://x.x.x.x./nagios instead of http://x.x.x.x/nagiosxi

[amit.ahuja]

Yes, I can log into core.

What are the contents of /etc/httpd/conf.d/nagiosxi.conf?

You can reset the nagiosadmin password with the following script

Code: Select all

/usr/local/nagiosxi/scripts/reset_nagiosadmin_password.php --password=<newpassword>

Hi, I reset the password, but the same issue still exists. It does not seem like the password authorization problem, because it does not prompt the username or password is wrong, just refreshes the login page.

Did you modify any of the httpd configuration files?

Any mysql errors?

Code: Select all

tail -f /var/log/mysqld.log

Finally, you do have cookies and sessions enabled in your browser correct?

[amit.ahuja]

I did not modify any of the httpd configuration files. In mysqld.log, i saw some errors as below,

Code: Select all

160322 11:23:00 [ERROR] /usr/libexec/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 13)
160322 11:23:00 [ERROR] Can't start server: can't create PID file: Permission denied

Also, I found I was not able to run /usr/local/nagiosxi/scripts/reconfigure_nagios.sh. I gave me this error.

Code: Select all

The only thing I did before this happens was that I changed the user of the directories in /var to nagios, then accessing web interface showed we needed to repair db. Then I changed the user back to root, then we were still not able to login.
