You should use a non-root user account as explained in the Ubuntu 20.04 Initial Server Setup.
1. Install MySQL Server
Let’s begin by updating the repository and installing the MySQL package for Ubuntu 20.04 using
sudo apt update && sudo apt install mysql-server
ENTER when prompted to install the MySQL package.
Once the package installer has finished, we can check to see if the MySQL service is running.
sudo service mysql status
If running, you will see a green Active status like below.
● mysql.service - MySQL Community Server Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2020-04-02 02:40:59 CEST; 2min 47s ago Main PID: 18476 (mysqld) Status: "Server is operational" Tasks: 27 (limit: 4915) CGroup: /system.slice/mysql.service └─18476 /usr/sbin/mysqld Apr 02 02:40:59 ubuntu2004 systemd: Starting MySQL Community Server... Apr 02 02:40:59 ubuntu2004 systemd: Started MySQL Community Server.
You may need to press
q to exit the service status.
2. Configure MySQL Security
You should now run
mysql_secure_installation to configure security for your MySQL server.
2.1. Validate Password Component (Optional)
You will be asked if you want to set up the Validate Password Plugin. It’s not really necessary unless you want to enforce strict password policies for some reason.
Securing the MySQL server deployment. Connecting to MySQL using a blank password. VALIDATE PASSWORD COMPONENT 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 component? Press y|Y for Yes, any other key for No:
ENTER if you don’t want to set up the validate password plugin.
2.2. Create Root Password
If you didn’t create a root password in Step 1, you must now create one here.
Please set the password for root here. New password: Re-enter new password:
Generate a strong password and enter it. Note that when you enter passwords in Linux, nothing will show as you are typing (no stars or dots).
2.3. Remove Anonymous Users
You will next be asked to remove anonymous users.
By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) :
ENTER to remove anonymous users.
2.4. Disable Remote Root Login
Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) :
ENTER to disallow root login remotely. This will prevent bots and hackers from trying to guess the root password.
2.5. Remove Test Database
By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) :
ENTER to remove the test database.
2.6. Reload Privilege Tables
Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) :
ENTER to reload the privilege tables.
You’re all done! 😀
2.7. Test MySQL Service
You can now log into the MySQL server. Because you are running this command as sudo, this will automatically log into MySQL using the MySQL root account. If you are prompted for a password, enter your Linux root account password, not the MySQL one.

To exit MySQL, type exit and press
You have now successfully installed and configured MySQL!
Now that your MySQL server is up and running, you might want to install phpMyAdmin for Ubuntu 20.04, which allows you to easily manage your MySQL users and databases through a browser interface.
Before installing phpMyAdmin, you must have Apache/Nginx and PHP installed first. Please refer to the following guides:
- Installing phpMyAdmin for Apache on Ubuntu 20.04
- Installing Apache on Ubuntu 20.04 with Virtual Hosts
- Installing PHP for Apache on Ubuntu 20.04 Server
- Installing phpMyAdmin for Nginx on Ubuntu 20.04
