I tried to log into the web interface and it says Database isn't running. So I ran the /usr/local/nagiosxi/scripts/repair_databases.sh and when I do that it runs the repair fine, but then it says "Starting mysqld [Failed]"
I tried to restarted and run the repair multiple times, but I get the same error.
- recovering (with sort) MyISAM-table 'tbl_variabledefinition.MYI'
Data records: 219
- Fixing index 1
MySQL Daemon failed to start.

Is the server's hard drive full?
That could cause the MYSQL daemon to not start up.
To check it, run the following commands as root.
Try running command to repair all of the databases on the server and then see if it starts up.
Run this as root
Code: Select all
mysqlcheck -f -r -u root -pnagiosxi --all-databases --use_frm
Then see id the MYSQL database starts up.
If it still doesn't start, you will have to look at the MYSQL or MariaDB log files to see why it is not starting and post the errors here.
Code: Select all
/var/log/mysqld.log
/var/log/mariadb/mariadb.log

I used your template VM, that came pre-configured with a specific size. I haven't really made any changes in a while. In any case it says I have 7.3 Size and 7.0 GB available. So here is all the output.
[root@localhost nagios]# df -h

I got it working. What happened was because the DB was corrupt, it filled up the log with errors every few minutes until it ran out of space. Now it's running. Any idea how I add space to the VM? For now it's running, but I'd like to add extra space

Did the server run out of space again?
Did you run the mysqlcheck command again?
I would increase the space of the hard drive, run the repair and see if that helps out.
The following instructions are how to increase the size of the hard drive it it is runnins as a virtual machine.

Not i didn't run out of space again, and I did run the MySQL check again. But what did work, was rebooting the box after the repair. Now it is working.

Thanks for the help, I will add space to prevent this in the future following the instructions above.

Your welcome. Glad the server is working now. Let us know if you have any further questions or that it is OK to lock the post.
