FOG 1.5.7 Update Database Issue
-
@notverypunny In a test setup I was able to revert back to mysql 5.7 without much trouble. It seems to be able to use the database that mariadb used as well. The only issue I see is that the systemd service files seemed corrupted on my test system:
ls -lah /etc/systemd/system/ | grep -e maria -e mysql lrwxrwxrwx 1 root root 35 Jul 22 20:10 mysqld.service -> /lib/systemd/system/mariadb.service lrwxrwxrwx 1 root root 27 Jul 22 21:16 mysql.service -> /lib/systemd/system/mariadbSo I am still wondering if it’s a good idea to simply revert the change back to
mysql-client mysql-serveror if I need to add a check and if someone is on MariaDB already I just leave it alone?!? -

MariaDB is the better db at this point from what I can see and I should think that most people would prefer it, especially on a new install.

Did you guys find a fix for this? I’ve just upgraded from 1.5.6 to 1.5.7 and the MariaDB service won’t start.
Thanks,

@FlangeMonkey When releasing 1.5.7 we did not expect this to be an issue but it turned out that moving from MySQL 5.7 to MariaDB is not yet properly supported by Ubuntu. It doesn’t do a merge of the DB over to the new version but simply shuts down the old MySQL DB (usually find that in
/var/lib/mysql-5.7/) and creates a fresh empty new one for MariaDB.and the MariaDB service won’t start.
While this sounds a bit different I can still imagine this being a similar case. Please run
sudo systemstl status mariadband post output here. As well runls -al /var/lib | grep mysqland post here. -
For all other users on Ubuntu out there. Please if you intend to update, use the current developer release 1.5.7.2 instead of plain 1.5.7 or wait till the next release is out. I just pushed out a fix that should address this current issue.

@Arrowtron Sorry to hear you have run into this as well. Unfortunately upgrading to 1.5.7.2 doesn’t help when you have gone to 1.5.7 already. We don’t do this as an automatic fix in the scripts as I find it too error prone to do in a scripted kind of way.
You should still have your “old” and valid database in
/var/lib/mysql-5.7. Please follow the steps outlined below and I hope you should be right back up again:sudo -i mv /var/lib/mysql /var/lib/mysql-mariadb apt-get remove mariadb-client mariadb-server cp -a /var/lib/mysql-5.7 /var/lib/mysql apt-get install mysql-client mysql-server systemctl start mysql -

Thanks for the reply,
I get this when i run the command
apt-get install mysql-client mysql-serverThere is a MySQL server running, but we failed in our attempts to stop it.
Stop it yourself and try again!Tried a few commands found doing a web search that didn’t help
apt --fix-broken installFailed to stop mysql.service: Unit mysql.service not loaded. invoke-rc.d: initscript mysql, action "stop" failed. invoke-rc.d returned 5 There is a MySQL server running, but we failed in our attempts to stop it.

You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: mysql-server : Depends: mysql-server-5.7 but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).=Update=
accidentally ran command sudo rm -rvf /var/lib
(thought i was typing in a new line, working too quick, was backing up mysql and purging etc) Going to start a fresh i think -

Stop it yourself and try again!Did you run
apt-get remove mariadb-client mariadb-serverbefore that? Kind of strange but you might have to kill the old DB process like thiskillall -9 mysqld…=Update=
accidentally ran command sudo rm -rvf /var/libI am sure you have a backup of that machine! Do you? Just recover that directory from your backup and proceed.
Run
apt --fix-broken installas suggested in the output and post what you get from this. -
Yes i ran
apt-get remove mariadb-client mariadb-serverDidn’t try this command, it might have helped for the unmet dependencies problem
killall -9 mysqldYes i have some SQL backup’s from previous upgrade which I have restored onto a new server (just had to change IP’s etc which is fine)
It’s on a virtual machine where as physical before, snapshots will come in handy for next time!Yes ran the apt --fix broken install and got the unmet dependencies for mysql errors. Didn’t have the time to keep looking into it
All goods, thanks for your help though!

@Arrowtron I am sure you know about there being various places in files and the DB where you have to change the IP address: https://wiki.fogproject.org/wiki/index.php/Change_FOG_Server_IP_Address

Yes found this Wiki when I was migrating, thank you
