Ubuntu is FOG's enemy

[Tom Elliott]

If, for some reason, you fail to follow the instructions.

The mysql -u root and apt-get -y remove unattended-upgrades commands can be run prepended with sudo to elevate privileges.

sudo mysql -u root
sudo apt-get -y remove unattended-upgrades

I concur with Tom’s post. I did write a huge thing I was going to post, but then realized it was like three pages long… so I deleted it. I’ll summarize that you’ll have less problems if you use RHEL, CentOS, or Debian for server OSs. Ubuntu is my favorite workstation OS, but I won’t use it for a server if I can at-all avoid it. And I do speak from some experience. Tom of course speaks from way, way more experience.

@Canonical I wish you’d stop changing stuff so much so often, and stop assuming that you know better than the administrator. If we set a setting via SQL manually, post OS installation, and post-mysql installation, you have no right to change it with an update that you push out at whim. I’m sick and tired of the unity-webapps-common package, I think it’s source code should be deleted forever. And I think that automatic updates via unattended-upgrades is complete bogus. Often I’ve found that even though I select “Do not update automatically” during the OS installation, the unattended-upgrades package still applies updates. This is evidenced by the message “You need to restart your server” when I log in via SSH. Then you went off and fell in love with Microsoft, I don’t approve of this. I think you’re too young to be in a relationship with such an older company. Surely, the older company will take advantage of you and you’ll end up pregnant with a WinBuntu baby, or worse get some kind of virus that you’ll need to see Dr. Symantec for.

My first post here, but I thought it timely to add this. This unattended-upgrades, up until 4/29, been setup to check for security updates only. In short, on that day (or rather, at 1am my time), it updated itself along with its configuration. You can see this in the log sample below. This of course wreaked some havoc on my production systems when it updated all sorts of packages and nuked everything. Needless to say, this feature is now permanently DISABLED.

In short … it updated itself along with its configuration.

Another example of Canonical thinking they know better than the administrator. It has never been ok to overwrite configuration set by the administrator, nor will it ever be. Updating the schema of a configuration file while preserving the configuration is one thing, but overwriting custom configuration is unacceptable.

@wanderson Have you tried replacing 127.0.0.1 with localhost?

[wanderson]

@Tom-Elliott

BD this mariaDB

[Avaryan]

Which linux distro is most preferred by the developers?

[wanderson]

@Tom-Elliott said in Ubuntu is FOG's enemy:

ALTER USER

Command mariadb?

[Tom Elliott]

@wanderson The alter user syntax is only a specific version of mysql and mariadb. IN the case of mariadb I believe it started with version 10.2, and for mysql it started with 5.7.

So, in your particular case, chances are the version of mariadb is not one that supports the alter user statement. That said, i only recommended the post as it seemed similar to what we’ve recently seen with CentOS 7. It does not mean this was the issue, but trying it wouldn’t hurt anything either.

The issue that brought you to this posting is most likely related to Max connections being used. I don’t know what settings will fix that for you.

@Avaryan I try not to specify a specific OS. This posting is mainly just informing users of potential issues we were/are seeing. I’m personally a fan of Fedora/Redhat/CentOS, but I try pretty hard to make our installer distro agnostic. For the most part we support the two main types found (Debian based, and Redhat based). We also support Arch.

If I had to say which one to use, I’d actually say CentOS as it’s stable, usually minimally offset from Redhat releases. Fedora would probably be the next one on the list, but in a “production” world I wouldn’t recommend it.

@Tom-Elliott It seems that so far this command has resolved:

SET PASSWORD FOR ‘root’@‘localhost’ = PASSWORD(‘’);
SET PASSWORD FOR ‘root’@‘127.0.0.1’ = PASSWORD(‘’);

chown -R apache:root /var/www/

Praying that the mistake will not happen again!

thanks!!!

@Tom-Elliott said in Ubuntu is FOG's enemy:

ALTER USER ‘root’@‘127.0.0.1’ IDENTIFIED WITH mysql_native_password BY ‘’;

I still have the error, can not I leave the mysql password blank?

[wanderson]

update mysql.user set plugin=‘mysql_native_password’;

CENTOS 7, Debian 8, or RHEL 7 are my preferences for production.

Fedora and Debian are my personal favorites for testing and development.

@Wayne-Workman

How difficult is it to migrate from an existing FOG server / FOG storage node running Ubuntu to Centos from a FOG perspective?

[Wayne Workman]

@Joe-Gill Easy, here’s the guide: https://wiki.fogproject.org/wiki/index.php?title=Migrate_FOG

[jacoboren]

Great I found this as solution for the same problem that suddenly appear here, i remove the “unattended-upgrades” from Ubuntu and I hope that don’t happen again. , solved!

Thanks @Tom-Elliott !

[Wayne Workman]

Hey there Canonical, you’re not doing yourself any favors when you change settings the admin has manually set. I hoped someone on your team would have read this thread and made changes accordingly to prevent the continuance of mayhem, but alas it seems nobody has… Don’t you have Google alerts setup when the words “Canonical” are used on-line?

@wayne-workman nice try wayne

Hello!

First of all, my English is terrible!

I downloaded CentOS 7 and FOG 1.4.4 today, with all updates, i follow exactly all the installation steps contained in FOG Wiki, even so i have the same problem described here.

I was able to resolve the issue with the instructions in that topic, in this case, as follows:

PS: At the time of installation I did NOT leave the mysql password blank, I set a password.

sudo -i
mysql -u root
set password for 'root' @ 'localhost' = password('password entered at the time of installation fog');
set password for 'root'@'127.0.0.1' = password('password entered at the time of installation fog');
update mysql.user set plugin = 'mysql_native_password';

That done, I was able to access the web GUI normally!

@wanderson and @Tom-Elliott, thank you so much!
