Install MySQL on Ubuntu

MySQL has been on Ubuntu’s repositories for a long time. To install MySQL follow the following steps

Update Packages and Repositories:

Let’s update the packages and repositories:

sudo apt-get update

Installing MySQL on Ubuntu:

Now let’s install MySQL on Ubuntu:

sudo apt install mysql-server

Security Script

Then, run the MySQL security script to harden the MySQL server:

sudo mysql_secure_installation
output

root@linuxify:~# sudo mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root: enter your root 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: 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 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) : 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!
root@linuxify:~#

Verifying MySQL has been Installed

Now that we have installed MySQL let’s verify the process is active and running:

systemctl status mysql.service
output

root@app:~# systemctl status mysql.service
* mysql.service - MySQL 8.0.29 database server
     Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2022-06-01 19:29:17 CEST; 4 weeks 2 days ago

If in your case the service isn’t up and running, you can start MySQL with the following command:

sudo systemctl start mysql
