Is there any way I can install only MySQL-server? Or that MariaDB thing must be installed? Thanks in advance.

Answer 1

You go to http://repo.mysql.com/ and choose a version

I have debian 9 so I choose

wget http://repo.mysql.com/mysql-apt-config_0.8.15-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.15-1_all.deb

Then you will be asked what you desire to install ... you say mysql Server

then you go as usual ...

sudo apt update 
sudo apt install mysql-server

and the rest you know probably ...
