How To Install MySQL 8.0 on Ubuntu 18.04 / 16.04

In this guide, we will cover how to install MySQL 8.0 on Ubuntu 18.04 and 16.04 LTS Server. If you have an old version of MySQL Server (e.g 5.7), you may need to do in-place upgrade or dump all data, upgrade packages and re-import all database data.

Before you can download MySQL v8.0 to your Ubuntu 18.04 or 16.04 Server, you need to add official MySQL Dev apt repository. Run below command:

$ sudo apt-get install wget
$ wget https://dev.mysql.com/get/mysql-apt-config_0.8.17-1_all.deb
$ sudo dpkg -i mysql-apt-config_0.8.17-1_all.deb
Selecting previously unselected package mysql-apt-config.
(Reading database ... 127849 files and directories currently installed.)
Preparing to unpack mysql-apt-config_0.8.17-1_all.deb ...
Unpacking mysql-apt-config (0.8.17-1) ...
Setting up mysql-apt-config (0.8.17-1) ...
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

Choose version when prompted.

Select <OK>  and press <Enter> key to confirm version installation.

Once the repo has been added, update apt index and install mysql-server:

sudo apt update
sudo apt install mysql-server

Accept license agreement in the next screens to begin installation.

Set root password for your MySQL database server.

Confirm your root password.

Agree to retain compatibility.

Select the default authentication plugin.

When asked for root password, provide the password and confirm it to set.

Confirm installed version of MySQL server:

$ apt policy mysql-server
 mysql-server:
   Installed: 8.0.19-1debian10
   Candidate: 8.0.19-1debian10
   Version table:
  *** 8.0.19-1debian10 500
         500 http://repo.mysql.com/apt/debian buster/mysql-8.0 amd64 Packages
         100 /var/lib/dpkg/status

From the output, you can see that the version installed is 8.0.19. 

You can start the application if stopped using:

sudo systemctl enable --now mysql

Check status using:

$ systemctl  status  mysql
