We don't use apt-get like in Debian or Ubuntu, but yum. mysql was replaced by mariadb, which is compatible, but - frankly said - better.

yum install mariadb-server mariadb

Then you'll connect (you don't need sudo for that!)

mysql -u root

If you set a password for accessing your database, you'd use

mysql -u root -p

run : install maria DB is a fork of MySql su -c 'yum -y install mariadb-server'

start service : service mysqld start

config mariaDB : mysql_secure_installation

later accesing to mysql and type the pass your pass ( 3 step) : mysql -u root -p

its all

Install mysql MariaDB

sudo dnf install mariadb mariadb-server

To start MariaDB on Fedora, execute the following command:

systemctl start mariadb.service

To autostart MariaDB on Fedora, execute the following command:

systemctl enable mariadb.service

After you started MariaDB (do this only once), execute the following command:

/usr/bin/mysqlsecureinstallation
