This tutorial has been written to help you install MySQL 8 on Debian 10 / Debian 9. This guide is for a fresh installation of MySQL 8.0 on Debian 10/9. If you have an older version of MySQL Server (e.g 5.7), you’ll need to do an in-place upgrade or dump all data, upgrade packages and re-import all database data to MySQL 8.0.

If you’re running Ubuntu 18.04 or Ubuntu 16.04 LTS system, use below guides instead:

How to Install MySQL 8.0 on Ubuntu 18.04 / 16.04

Follow steps below to Install MySQL 8.0 on Debian 9 / Debian 8.

Step 1: Add MySQL Dev apt repository

MySQL 8.0 packages are available on official MySQL Dev apt repository.

sudo apt -y  install wget
wget https://repo.mysql.com//mysql-apt-config_0.8.13-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb

Agree to configure MySQL Apt repository.

Confirm addition of MySQL 8.0 repository as default when prompted.

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

Step 2: Install MySQL 8.0 on Debian 10/ Debian 9

Once the repository has been added, install MySQL 8.0 on Debian 10 / Debian 9 by running the following commands:

sudo apt update
sudo apt -y install mysql-server

When asked for the rootpassword, provide the password.

Re-enter root database user password.

Select the Authentication plugin and select <OK> to finish installation of MySQL 8.0 on Debian 10 / Debian 9.

Check version installed using the apt-policycommand:

$ apt policy mysql-server
mysql-server:
  Installed: 8.0.13-1debian9
  Candidate: 8.0.13-1debian9
  Version table:
 *** 8.0.13-1debian9 500

        100 /var/lib/dpkg/status
     5.5.9999+default 500
        500 http://httpredir.debian.org/debian stretch/main amd64 Packages

The mysql service should be started by default, you can confirm service status using the command:

Step 3: Test MySQL 8.0 Installation on Debian 9 / Debian 8

Let’s test to confirm if MySQL 8.0 installed on Debian 10 / Debian 9 is working as expected.

Login as root user with a created password:

$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.13 MySQL Community Server - GPL

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> SELECT VERSION();
+-----------+
| VERSION() |
+-----------+
| 8.0.13    |
+-----------+
1 row in set (0.00 sec)

Create a Test database and user.

CREATE USER 'test_user'@'localhost' IDENTIFIED BY "Jek1oleiboafei4eeghu";
CREATE DATABASE test_db;
GRANT ALL PRIVILEGES ON test_db.* TO 'test_user'@'localhost';
FLUSH PRIVILEGES;
QUIT

Try to access the database console as test_user:

$ mysql -u test_user -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 9
Server version: 8.0.13 MySQL Community Server - GPL

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| test_db            |
+--------------------+
2 rows in set (0.01 sec)

mysql> QUIT

Once confirmed to be able to login and use assigned database, login again as root user and drop both the test database and user.

mysql> DROP DATABASE test_db;
Query OK, 0 rows affected (0.11 sec)

mysql> DROP USER 'test_user'@'localhost';
Query OK, 0 rows affected (0.11 sec)

mysql> SELECT USER FROM mysql.user;
+------------------+
| USER             |
+------------------+
| mysql.infoschema |
| mysql.session    |
| mysql.sys        |
| root             |
+------------------+
4 rows in set (0.00 sec)

mysql> QUIT
Bye
