To check that the file downloaded, type:
root@kvmde68-19464:~# ls mysql-apt-config_0.8.15-1_all.deb ubuntu-echo
Next, unpack and install it:
sudo dpkg -i mysql-apt-config
Next, a window will appear in which you should check that it is MySQL Server & Cluster (Currently selected: mysql-8.0)
Next, enter the following commands:
sudo apt update
sudo apt upgrade
Install MySQL server:
sudo apt install mysql-server
A window will open in which you need to enter a new root password for MySQL (Ubuntu and MySQL passwords may be different)
Next, let's click Ok
In the window, where it says about new MySQL 8 Authentication - click Use Strong Password Encryption (Recommended)
Next, we enter the command:
Enter the MySQL password.
From there, the security questions can be answered as follows
root@kvmde68-19464:~# mysql_secure_installation Securing the MySQL server deployment. 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: N Using existing password for root. Change the password for root ? ((Press y|Y for Yes, any other key for No) : n ... skipping. By default, a MySQL installation has 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) : y Success. 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) : y Success. 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) : y - Dropping test database... Success. - Removing privileges on test database... Success. 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) : y Success. All done!
To check that MySQL is working, we type:
systemctl status mysql
