Check MysQL Status
Check MysQL Status

If there is no active keyword in the return of the above command, then the service is in a stopped state, and you need to start the database service before proceeding to the next step:

# systemctl start mariadb
------------- CentOS/RHEL 6 and Fedora ------ -------
# /etc/init.d/mysqld start
Next, we will log into the database server as root:

# mysql -u root -p
For compatibility with different versions, we will update mysql with the following statement The user table of the database. Note that you need to replace YourPasswordHere with the new password you chose for root.

MariaDB [(none)]> USE mysql;
MariaDB [(none)]> UPDATE user SET password=PASSWORD('YourPasswordHere') WHERE User='root' AND Host = 'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES ;
To verify that the operation was successful, exit the current MariaDB session by entering the following command.

MariaDB [(none)]> exit;
