Press Enter. When prompted for password, provide the root password set above
Enter current password for root (enter for none): <Enter password> VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y|Y for Yes, any other key for No: Y There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 Using existing password for root. Estimated strength of the password: 25 Change the password for root ? ((Press y|Y for Yes, any other key for No) : d Remove anonymous users? [Y/n] Y Disallow root login remotely? [Y/n] Y Remove test database and access to it? [Y/n] Y Reload privilege tables now? [Y/n] Y Thanks for using MariaDB!
Check MySQL version
Connect to MySQL to check MySQL installed version. To connect to MySQL, run the below command:
mysql-u root -p
Provide the root password set above and once connected, execute the command as below to display MySQL version.
SELECT VERSION() | VERSION() | +-----------+ | 8.0.21 | +-----------+ 1 row in set (0.00 sec)
Step 4: Create MySQL User (Optional)
While still connected to MySQL, run the following commands to create a user:
CREATE USER 'lorna'@'%' IDENTIFIED BY 'MyStrongPass.'; GRANT ALL PRIVILEGES ON * . * TO 'lorna'@'%'; FLUSH PRIVILEGES; exit
Step 5: Enable MySQL remote access (Optional)
By default, MySQL remote access is disabled. To enable it we need to edit mysqld.cnf file as below:
$ sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
Look for the line ‘bind_address’ and change as below:
# By default we only accept connections from localhost #bind-address = 127.0.0.1 bind-address = 0.0.0.0
Save the file and restart mysql
$ sudo systemctl restart mysql
Allow remote connections through the firewall
$ sudo ufw allow from <remote_IP_address> to any port 3306 $ sudo ufw enable
To access the database from a remote machine, run the following command:
$ mysql -u user -h database_server_ip -p
