I try to run the command:
sudo systemctl start mysql
And receive the following message:
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
Then when i type:
sudo systemctl status mysql.service
I get the following message:

I searched for hours and couldn't come with a solution... does anyone know what could be the error?
The only thing i did before that was to install mysql-server with the command:
sudo apt-get install mysql-server
I tried installing and reinstalling, updating and upgrading ubuntu, i'm not sure if this would help.
Thanks in advance!
UPDATE:
I just checked, and don't have the /var/lib/mysql directory in my computer. But i failed to get it by reinstalling mysql server/client.
I fixed by "purging" every file related to mysql and reinstalling mysql-server:
sudo apt-get purge mysql-server mysql-client mysql-common
sudo apt-get install mysql-server
In my case the issue is raised b.c the server storage is full.
removing some logs and files solved and then restarting it solved the problem.

After reading this:
Problems installing MySQL on Ubuntu 20.04
dpkg: error processing package mysql-server (dependency problems)?
I've tried this:
sudo systemctl stop mysql
sudo apt clean
sudo apt purge mysql*
sudo rm -rf /etc/mysql /var/lib/mysql /var/log/mysql
sudo apt autoremove
sudo apt autoclean
sudo apt update
sudo apt dist-upgrade
sudo apt install -f
sudo apt install mysql-server
But I'm still getting the same error
Then I read this:
I did not manage to install mysql on Ubuntu completely
So I tried
sudo mysql_secure_installation
but then I got this error:

I am running Ubuntu Server 22.04.1 LTS on a LXC with 4GB of RAM and one CPU core

Ok so all of a sudden sql is not working properly on my server. When i run sudo service mysql start it says:

See "systemctl status mysql.service" and "journalctl -xe" for details.
When i run systemctl status mysql.service it shows:

Any help is appreciated
First run " sudo apt-get install -f" for resolve dependences, if it doesn't works, review your config files, permission, etc. Try to see if thare is any update that happened.
In the last case, when nothing works. Try to reinstall by "sudo apt-get autoremove mysql-server && apt-get install mysql-server" but make sure you have all backups os config files and sql...
I don't know if it will really help, but in my job we receve some updates in the server from night to the day that pull all down kkk. After some bad experiences i create the backup of the backp of the backup daily...

Looks like the apache2 file is not available on server.
/usr/sbin/apache2 is provided by apache2-bin. apache2-bin is a dependency of the apache2 package, so apache2 will not work properly without it. Open the terminal and type:
sudo apt install --reinstall apache2-bin
sudo service apache2 start
Can you please attach error logs or the output of "systemctl status apache2.service"
My Best Solution No Need Restart .. After Long Time of se :)
sudo apt-get --reinstall install apache2-bin
Step 1: Stop nginx & Start apache
That's it.
service nginx stop
systemctl restart postgresql
systemctl restart apache2
systemctl status apache2.service
Previously I performed the migration of my database from one directory to another within the server itself (/var/lib/mysql to /mnt/mysql) for lack of space.
When starting the server again, after having changed the /etc/my.cnf with the correct directory it returns me this error:
$ systemctl start mysqld
Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.
And when I run the systemctl status command on the mysqld service it returns me:

If it is permission error, how do I free the server to accept such a directory?
Note: I am using CentOS 7
Thank you!!
If you are using Linux or Unix Server then you should check the permissions of the user to access the service. Here I can see that the user which is logged in can't access the service because of the permission problem.
Try with.
sudo systemctl start mysqld;
Or try sudo su;, enter the creds of the superuser and then try to check the service status.
Or login as superuser and then try to start the service.
Hope this may help you.
After searching i discovered that the error was the 'enforcing' permission of SELINUX.
The answer to fix this problem is:
$ sudo setenforce 0
And the server went up normally.
Are you logged in with root user?
If no, try with sudo.
Otherwise, I think is better to restart your system and try again.
If you aren't expert in linux centos don't manipulate anything.
uninstall mysql and reinstall it.
first i have tried to uninstall both of them

This is the error that's throw me when i tried to connect
root#thaali:/etc/mysql# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Can any one please help me to solve this and i have seen in some places i have edit etc/my.cnf to fix this in my case i don't have such a file
This one is really weird for I was not dist upgrading. One day it just didn't work.
When I tried journalctl -xe I got this
...
Oct 05 08:51:26 <servername> mysql-systemd-start[10914]: ERROR: Unable to start MySQL server:

...
I fixed it by doing this:
sudo mkdir /var/lib/mysql-files
sudo chown -R mysql:mysql /var/lib/mysql-files/
sudo chmod 700 /var/lib/mysql-files/
sudo service mysql restart
Restarting the service didn't actually fix all problems I was having so I ended with rebooting the machine.
