mostly other service is running on the same port (3306) ,
try
netstat -pnltu | grep -i "3306"
it will show all services running on that port , if there are any , just end it and restart your Mysql server
I don't know why this error

How to free up more space.
I want to start or extract the database normally
Given rsyslog is complaining about 'No space left on device' I suspect that mysql will have the same problem. It needs space to work as well.
journalctl -u mysqld.service
to see mysql errors, though it is probably also having limited recording due to out of space.
Fix the amount of free space on your storage and make all your programs happy.
I just installed MySQL 5.7.23 on Centos 7. As soon as I do systemctl start mysqld gives me an error. Making systemctl status mysqld returns:

There can be various reasons for this issue.
Required folder permissions may not be there.
Please find the answer related to folder permission here.

You may have less RAM free with the MySQL service stopped, so as soon as you run:
systemctl start mysqld
MySQL is attempting to utilize more than what’s available and since it’s unable to do so, it fails.
For database-driven websites, I recommend at least 1GB of RAM minimum. if you still want to run with less MB of RAM then I’d recommend NGINX over Apache.
I tried to reinstall MySQL and now it doesn't even start, and if I go to "messages" it says this
Jul 23 11:04:27 systemd: Starting MySQL Server...

i know that vendor preset: disabled is fine
i have changer the chown for mysql directory
even the chown for mysql.sock changed it three times
and still getting the same error
So any help will be thankful even if you are new
