Error 1396 while upgrading

Sebastian Roth

@xburnerx00 Never saw this error before but I can imagine what is causing this. Please run grep snmysqluser /opt/fog/.fogsettings and post output here.

Did you run the installer using sudo?

The Permission denied message might be a bit misleading but it’s just telling you that you cannot execute that log file. If you want to read that log file on the console you need to use a tool to open it, like less /root/fogproject/bin/error_logs/fog_error_1.5.9.log

Yes, I re-ran installer making sure to use sudo, but came back with same issue. Here are the results of the command you asked for.

[root@fogserver bin]# grep snmysqluser /opt/fog/.fogsettings
snmysqluser='fogstorage'

Don’t use sudo directly to call the installer. Switch to a full root user environment (e.g. via sudo su - or sudo -i) and run the FOG installer from there.

Just doesn’t make sense why it would say Operation CREATE USER failed for ''@'localhost' (username before the @ obviously being empty)!?

Please run cat /root/fogproject/tmp/fog-db-and-user-setup.sql and post the full output here. Be aware there are two lines with a password in it - look for IDENTIFIED BY and mask the passwords in the output.

@sebastian-roth
I was already running installer with sudo -i, but I also went back and tried it with sudo su - but with same result. Ran command. I deleted the passwords for this post.

@xburnerx00 I still am very much at a loss on why the DB username is empty while it shouldn’t be. I will go through the installer code again and see what I can find.

Did you extract the installer from ZIP or tar.gz or is this a repo clone from GitHub?

xburnerx00

@sebastian-roth

I have done an update before. I forget what the beginning version for me was, but I believe I may have done that install with tar.gz. I was following the installation instructions from the wiki. When I updated to 1.5.9RC1, just before last summer I believe, I did that one through github. I only say that because I remember asking to have that site open since our firewall was blocking it. Now I am using github to update. I ran these commands for the update I am attempting now from another post.

cd /root/fogproject
git checkout master
git pull
cd bin
./installfog.sh

Separate thing I noticed was that I was trying to use the GUI to navigate to the .sql file but it has an X on the root folder.

Not sure if that means anything. I cannot open it. Forgive me for not being more in depth if needed, I am new to linux.

[root@fogserver bin]# grep snmysqluser /opt/fog/.fogsettings
snmysqluser=‘fogstorage’

I went over this too quickly because at first I expected the variable to be empty and so I didn’t quite notice it to be set to fogstorage which is not the default on a FOG master node but usually on a FOG storage node. Do you remember manually adjusting the DB username in /opt/fog/.fogsettings at some point?

While I still don’t understand why this would cause this exact error I am wondering what you get when running grep DATABASE_USERNAME /var/www/html/fog/lib/fog/config.class.php

As well run git status to see if you have any local modifications in the repo. If the output is empty, it’s all fine.

The git commands used seem fine and /root not being accessible in the GUI is right too.

xburnerx00

@sebastian-roth

I may have changed something during that first update, I vaguely remember changing a username.

[root@fogserver bin]# grep DATABASE_USERNAME /var/www/html/fog/lib/fog/config.class.php
        define('DATABASE_USERNAME', '');

Sebastian Roth

@xburnerx00 Please try the following: Edit /opt/fog/.fogsettings (as root) and set snmysqluser='fogmaster'. Then re-run the installer.

xburnerx00

@sebastian-roth
I changed snmysqluser to ‘fogmaster’. It was previously ‘foguser’. Re-ran installer. It stopped at same error.

I thought it was ‘fogstorage’?! Something is very strange here.

Now let’s see if we can get your FOG web UI back up by manually editing /var/www/html/fog/lib/fog/config.class.php. We saw the DATABASE_USERNAME was empty too. Put in fogstorage (as we had that in fogsettings initially I think), make sure a non-empty password is defined the line below the username, save the file and try to open the FOG web UI URL in your browser. No restart of services needed.

xburnerx00

@sebastian-roth
I set the name ‘fogstorage’. There was already a randomly generated password in the line below.

No success opening WebUI.

private static function _dbSettings()
    {
        define('DATABASE_TYPE', 'mysql'); // mysql or oracle
        define('DATABASE_HOST', 'localhost');
        define('DATABASE_NAME', 'fog');
        define('DATABASE_USERNAME', 'fogstorage');

Sebastian Roth

@xburnerx00 Do you know the DB root password? Can you login to the database in the console? mysql -u root -p (if you don’t know the DB root password try just ENTER for an empty password - but the 1.5.9-RC1 installer should have forced you to set one on CentOS I think)

You can also try out different usernames in config.class.php… fogmaster, root - see if any of those works.

I am still scratching my head in what happened here.

xburnerx00

@sebastian-roth

Yes, I know the root password.

[root@fogserver ~]# mysql -u root -p

Found and fixed - the .fogsettings file was clearly corrupted causing this issue. Very sure this was due to manual editing.
