Blank Screen

[rentsys]

Nagios goes into a blank white screen once I click Access Nagios XI from the welcome page. How do I fix this?

It may be that postgres or mysql are not started. Can you tail the error log and access log and show the output? Try to access the web interface, and then immediately after, run the following and show the output:

Code: Select all

tail - 50 /var/log/httpd/error_log

tail - 50 /var/log/httpd/access_log

service postgresql restart

service mysqld restart

I got the same error but my customer turned off machine on vmware botton "turn off" direct.

If you run service mysql status that return the stoped status.

You can remove file /var/lib/mysql/mysql.sock and execute command service mysql start,

After you can check again the web access.

Thanks

Ah, a stuck sock file, this was likely due to someone shutting down the system improperly, be sure they issue:

Code: Select all

shutdown -h now

So the server has time to gracefully exit out the processes, and shut down services. You may want to check for table corruption now:

Thanks, this can be closed.
