Installing MySQL Server

• Install the MySQL server by using the Ubuntu operating system package manager:

sudo apt-get update
sudo apt-get install mysql-server

If the secure installation utility does not launch automatically after the installation completes, enter the following command:

sudo mysql_secure_installation utility

Allow remote access

If you have ip tables enabled and want to connect to the MySQL database from
another machine, you must open a port in your server’s firewall (the default
port is 3306). You don’t need to do this if the application that uses MySQL
is running on the same server.

Run the following command to allow remote access to the mysql server:

sudo ufw enable
sudo ufw allow mysql

Start the MySQL service

After the installation is complete, you can start the database service by
running the following command. If the service is already started, a message
informs you that the service is already running:

sudo systemctl start mysql

Start the MySQL shell

There is more than one way to work with a MySQL server, but this article
focuses on the most basic and compatible approach, the mysql shell.

1. At the command prompt, run the following command to launch the mysql shell and enter it as the root user:

/usr/bin/mysql -u root -p

Installing MySQL Workbench

Step 1: Download configuration file from the apt repository

Using this method, you can install MySQL from the official apt
repository. For this purpose, download the repository configuration file
from the given URL https://dev.mysql.com/downloads/repo/apt/.
When you browse this URL, it will take you directly on the download
page from where you will download ‘mysql-apt-config_0.8.15-1_all.deb’ ( You might get latest version hence version no may be changed )
repo configuration file. Click on the Download option.

On the next page, it will ask you either you want to register or log in. If you don’t want to select these options then, click ‘No thanks, just start my download’ link to download the required package to your system’s local directory.

Step 2: Installation of MySQL Workbench

Use the following command to add MySQL repository URLs in the apt
sources list so that you can install the software on your Ubuntu 20.04
system.

cd Downloads

sudo apt install ./mysql-apt-config_0.8.16-1_all.deb

Step 3: Update apt-cache

Update the apt cache using the following command to update the configuration URLs.

sudo apt update

Step 4: Installing MySQL Workbench on Ubuntu 20.04

Now, it’s time to install MySQL workbench using the apt repository.
To do that, execute the following command to install MySQL workbench.

sudo apt install mysql-workbench-community

Step 5: Launch MySQL Workbench

Once the installation is complete, you will finally launch the MySQL
Workbench on your system. You can launch it using the terminal by typing
the following command:

mysql-workbench

You are DONE!

But wait a minute, It is equally important to know how to uninstall MySQL and MySQL Workbenc

Uninstall MySQL

• Make sure MySQL is not running:

sudo systemctl stop mysql

• Then purge all of the MySQL packages:

sudo apt purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*

• Then delete all of the MySQL files:

sudo rm -rf /etc/mysql /var/lib/mysql /var/log/mysql

• Finally clean all packages that are not needed:

sudo apt autoremove
sudo apt autoclean
