Storage node testing and disk information not displayed

[Chris_bne]

Hello,

Firstly, thanks to the devs. Fog is excellent.

I have deployed a storage node and have a couple of questions.

[LIST]
[]I am using the location plugin, how can I test to be sure the image is being pulled from the correct storage node? Everything seems ok in testing I just can’t find the log to confirm. I don’t want to flood the WAN with image traffic.
[]The web GUI disk information does not work for my storage node. It just says failed to connect

Any ideas?
Thanks

I’ve never used the location plugin, so I can’t speak for that.

I had the failed to connect problem as well and narrowed it down to a MySQL config change. In my.cnf, I had to comment out the bind-address line for 127.0.0.1 and restart mysql. I also had to make sure the server config was correct in Config.class.php. Maybe check those 2 things?

[Chris_bne]

Thanks Ben.

I removed the location plugin after a design re-think, but it hasn’t changed the GUI problem.

Thanks for the suggestions I’ll have a go now.

From the node… can you login to the fog servers mysql database?

I also keep getting the ‘failed to connect error’. Could you please explain to me there the 2 files that you referenced are located so I can check to see if that is where my problem is?

[Wolfbane8653]

cassie,

Can you supply the Fog Server OS and the Storage Node OS?

[Ben Warfield]

Hi cassie,
The fix for me worked on Fog 1.1.2 on Ubuntu 12.04.

For the mysql part, the file I changed is at /etc/mysql/my.cnf Find the line that says bind-address = 127.0.0.1 and put a # in front to comment it out. Save the file and do a “service mysql restart” to reload the configuration.

Then in the fog config files, I edited /var/www/fog/lib/fog/Config.class.php and had to enter the correct mysql connection info in the db_settings function.

[cassie_280]

Both my fog server and my storage node are using Ubuntu 14.4.

can you please elaborate what you mean by “correct mysql connection info in the db_settings function.”

Thank you!

[cassie_280]

I did notice that between my FOG server and the storage node the TFTP_FTP_PASSWORD value was different. I changed that line so they matched and restarted mysql, but I still am receiving the same error.

[Ben Warfield]

In the Config.class.php file, there’s a section not too far from the top of the file that starts with “private static function db_settings()”.
Database_host should most likely be ‘localhost’ unless you have your database stored somewhere else
Database_name should be fog
Database_username and Database_password should be an account with access to the fog database. I’ve changed my username/password so I can’t tell you for sure what the default is

[cassie_280]

On the server username is root, and password is null. On the node the username is fog storage and the password is password.
I’m guessing that’s where my problem is?

[Tom Elliott]

Yes,

the Storage node password for the (fogstorage) user is found in:

FOG Configuration Page->FOG Settings->FOG Storage Nodes->FOG_STORAGENODE_MYSQLPASS

[cassie_280]

Tom,

I changed that password in the GUI because I was unsure what the default was and I had to enter the credentials when I was installing FOG.
So the credentials in my storage node currently match what is in that location.

[Tom Elliott]

If you’re comfortable with the mysql syntax, you’re more likely going to have to change the fogstorage password in the db then.

To do this the syntax should be:
[code]SET PASSWORD FOR ‘fogstorage’@‘%’ = PASSWORD(‘new-password-here’); FLUSH PRIVILEGES;[/code]

This should help out.

[cassie_280]

Where do I enter that?

[Tom Elliott]

You need to login to the mysql instance. From a terminal on the FOG server run the command:

[code]mysql -u root fog[/code]

Then run the above command.

[cassie_280]

Return said “Query OK, 0 rows affected (0.00 sec)”
I restarted mysql and I’m still having the same issue.

Is it possible that I could just change the password in the GUI and in the node back to the default (whatever that is)?
The only reason I changed it was because I had no idea what it was and it was in hidden characters.

[Tom Elliott]

The default is a randomly generated one performed at install time. It only happens the first install.

The fact that it reports 0 rows affect tells me, it seems, that updating this field is working properly as well.

A test you could do could be to sign in to mysql using the password you set and the same info:

[code]mysql -u fogstorage -p’<your-fogstorage-pass-here>’ fog[/code]

Does it allow you in with this? Also, is the /etc/my.cnf bind-address commented out?

[cassie_280]

Yes, I was able to log in with those credentials, and yes the bind-address is commented out.
I restarted the mysql service and I still get the failed to connect error.

[Tom Elliott]

Now,

From the storage node, can you perform the same command, just adding -h’IPOFFOGSERVER’
