My database connection appears to be invalid?

@Wayne-Workman
Okay, sorry Wayne, your post got lost in my text walls.

[ullsadmin@localhost ~]$ mysql -D fog
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

This is beyond my knowledge…
EDIT: Restarting mysqld fixed the issue. Now I will see if it stays after reboot…
EDIT2: It does not stay, boooo.

@AngryScientist When it throws the error again, try these and see if one works:

mysql -D fog -u root -h localhost

mysql -D fog -u root -h 127.0.0.1

I have the exact same error now… great.

@Tom-Elliott Moving this to bug reports.

This sounds like a mariaDB (aka mySql) issue. And it sounds like it’s just not configured to start on startup if systemctl start mysqld.service fixes it. This article might could help.
https://mariadb.com/kb/en/mariadb/starting-and-stopping-mariadb-automatically/

I thought that the database got configured to automatically start on the apt-get/yum install.
I have cent os 7 and have never had to do any sort of configuration for fog services to run on startup.

In centos 7 the way to start maridadb on boot is probably:
systemctl eanble mysqld

I’m still waiting to hear back on the commands I posted.

[AngryScientist]

@Wayne-Workman

systemctl enable mysqld

Typo correction!

I will reboot my FOG server later today and give you the results of your suggestions. Right now I am reveling in the wonders of 5GBps imagine speed. 1.2.0 on my old hardware topped out at 1.2GBps

A lot of that has to do with the performance improvements of FOG 1.3.0 RC, a change was made to how the images are compressed and decompressed for imaging and some people reported 50 to 100% speed increases.

RC-22 Officially released.

Please update and hopefully you’ll see all the latest goodies and what not. (Hopefully this will be fixed for you too.)

@Tom-Elliott
I know how to do a git pull, but what is the official upgrade procedure?

[Wayne Workman]

@AngryScientist here:

https://wiki.fogproject.org/wiki/index.php?title=Upgrade_to_trunk

[Tom Elliott]

In very simple terms:

https://wiki.fogproject.org/wiki/index.php?title=Upgrade_to_trunk

Essentially, open a terminal.

Cd to the installer directory.

If you loaded the repo from git, make sure you’re on the dev-branch:

git checkout dev-branch

Ensure you’re environment is setup without customizations:

git reset --hard

Pull the latest:

git pull

Cd to the BIN directory:

cd bin

Install as normal.

./installfog.sh -y

@Tom-Elliott

Time to un-zombie the thread.

I updated to RC-36, and same same. I had to sudo systemctl start mysqld to get the database connection running.

[Tom Elliott]

@AngryScientist Are you sure it wasn’t:

systemctl start mysql or even systemctl start mariadb?

I’m trying to validate what the problem is here, and I’m fairly sure we’d have seen a bunch of issues with this operationally speaking. (We have a bunch of people using CentOS 7).

@AngryScientist It would be interesting to know if the contents of your .fogsettings file is messed up and then upgrading caused the installer to look at bad data again??

My production server is running Centos 7, I think we are on RC34 and that upgraded cleanly.
