Step 1: Update Your System

Hit the below command to get the latest packages installed.

sudo apt update -y

Step 2: Add MySQL Repository in Ubuntu 20.04

Ubuntu already have the default MySQL repository but in our case we’ll add the repository (latest) to install the MySQL. So, type the follwoing command in your terminal.

wget https://dev.mysql.com/get/mysql-apt-config_0.8.12-1_all.deb

When the download finished, install the repository with the help of below command

sudo dpkg -i mysql-apt-config_0.8.12-1_all.deb

You’ll be prompted, select the Ubuntu Bionic & then click “Ok”.

In the next prompt, choose MySQL 8.0 Server (mostly it is selected by default) and then click “OK”.

Then in next prompt, choose MySQL 8.0 Version and click “OK”.

In next step MySQL will be selected by default. Choose the last option OK and then click “OK“.

Step 3: Update MySQL Repository on Ubuntu 20.04

Fire the below command to get the latest repositories packages installed.

sudo apt-get update

And then search for the MySQL 8.0 with the help of apt cache command as shown below:

sabi@Ubuntu20:~$ sudo apt-cache policy mysql-server
mysql-server:
Installed: (none)
Candidate: 8.0.22-1ubuntu18.04
Version table:

Step 4: Install MySQL on Ubuntu 20.04

As we’ve seen above the MySQL 8.0 is listed in our Ubuntu 20.04 system, so install it by typing the below command in terminal. Press “Y” when prompted to continue.

sabi@Ubuntu20:~$ sudo apt install mysql-server

mysql-community-client-core mysql-community-client-plugins mysql-community-server
mysql-community-server-core mysql-server
The following packages will be upgraded:
mysql-common
1 upgraded, 12 newly installed, 6 to remove and 5 not upgraded.
Need to get 31.1 MB of archives.
After this operation, 96.8 MB of additional disk space will be used.
Do you want to continue? [Y/n] y

Provide the root password when prompted to continue. Re-enter to verify the password.

Use the strong password encryption as recommended by MySQL.

Step 5: MySQL Secure Installation

For security reasons, to secure the installation type

sabi@Ubuntu20:~$sudo mysql secure_installation
Enter current password for root (enter for none):
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

Then Press “Enter“. When prompts for root password, provide the root password.

Verify the MySQL version with the help of below command after login to the MySQL.

sudo mysql -u root -p
SELECT VERSION()
| VERSION() |
+-----------+
| 8.0.21 |
+-----------+
1 row in set (0.00 sec)

Step 6: Enable MySQL Remote Access (Optional)

By default remote access for MySQL is disabled, you can enable it if you needed by editing the below file.

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Here search for the line “bind_address” & do the changes as shown below:

#By default we only accept connections from localhost
bind-address = 127.0.0.1
bind-address = 0.0.0.0

Then save and exit the file.

And restart mysql

sudo systemctl restart mysql

And allow the remote connections through the firewall.

sudo ufw allow from to any port 3306
sudo ufw enable

To access the database from remote system, type

mysql -u user -h database_server_ip -p

So, this is how you can install MySQL 8.0 on Ubuntu 20.04
