Have downloaded MySQL repository through the APT repository, then already did sudo apt-get update and sudo apt-get install mysql-server. But I got the error below:
asus#asus-K40IJ:~$ sudo mysqld

Why is this and how to solve this..?
It is not recommended to run 'mysqld' as root for security. But you can do it with '--user=root' option.
Please see for more details.

MySQL will not start on my Ubuntu 22.04 LTS server. It was working for a few months but then got caught in the following loop that appears to be due to a server upgrade it tries to run when it starts:
2022-11-04T18:40:51.568052Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.31-0ubuntu0.22.04.1) starting as process 8978

My logs are just repeats of those lines over and over again.
From the logs, I am guessing the upgrade script is trying to run a query that requires DROP PRIMARY but I can't find that query.
I have tried rebooting the server and restarting with systemctl. Neither changed the behavior.
I have tried to uninstall mysql-server from the command line but it says that it is only partially installed and then tries to install and run it generating the same errors as above.
When I try to kill it, it just respawns seconds later.
How can I fix this error loop?
I tried re-installing mysql-server but it did not work. I needed to disable mysql, uninstall it, purge it, clear the configs, and THEN reinstall.
I was able to stop the error loop with the following code:
sudo systemctl stop mysql
sudo systemctl disable mysql
sudo apt remove --purge mysql*
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /etc/mysql /var/lib/mysql /var/log/mysql
sudo apt-get install mysql-server
The disable was key to stopping the loop and the rm from the etc folders did not cause an error on install.

I've been working through MySQL but I've been having trouble entering my MySQL server to change certain properties. When I attempt to enter as root I get the following output:
//]$ sudo mysqld -u root -p
Enter password:

Can't figure out how to sort this out. Any help would be much appreciated.
keyring-migration-source exists in one of the configuration files.
mysqld --help --verbose will list which files are read at the top. Look in those and remove the line.
Also don't run mysqld as root. Its a security hazard and won't start. Use the systemctl start mysql that fedora provides.
I tried to start MYSQL in safe mode to reset the root password, but getting the below error.
I had mysql server installed on my mac, yesterday i encountered some error where it was repeatedly shutting down automatically. However i wasn't able to connect to server using command line as it was erroring out mentioning the root password was wrong. Though I was able to connect using mysql workbench.
I reinstalled SQL Server and still not able to login using the new root password.

I am looking at these instructions to reset the mysql root password on an Ubuntu development machine.
#> sudo /etc/init.d/mysql stop
[ ok ] Stopping mysql (via systemctl): mysql.service.
Seems to work but then
#> sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking

This process exits. Afterwards, when I try

What's going wrong?
I've waded through forum post after forum post. I can't figure this out. I'm using CentOS 6.5, which had MySQL 5.1, but I need 5.5! I've been looking at a lot of posts but the main one I've been using as my go to manual is this one. I've attached a step by step of what I have done and their results. I
can tell that I have 5.5, but I can't get it to start.

Installation of system tables failed! Examine the logs in /var/lib/mysql for more information.
You can try to start the mysqld daemon with:
shell> /usr/libexec/mysqld --skip-grant &
and use the command line tool /usr/bin/mysql to connect to the mysql database and look at the grant tables:
shell> /usr/bin/mysql -u root mysql
mysql> show tables
Try 'mysqld --help' if you have problems with paths. Using --log gives you a log in /var/lib/mysql that may be helpful.
