This guide will demonstrate how to install MySQL 8 on Debian 9.
Install MySQL 8 on Debian 9
To install MySQL 8 on Debian 9, we are going to use MySQL APT repository which provides deb packages for installing and managing the MySQL server, client, and other components.
Run System Update
Update your system packages.
apt update
apt upgradeAdd MySQL APT Repository
MySQL APT repository is not available on the default Debian 9 system software repository list. Therefore, download the repo and install it as shown below;
wget https://repo.mysql.com//mysql-apt-config_0.8.13-1_all.debapt install ./mysql-apt-config_0.8.13-1_all.debDuring the installation, you will be prompted to select MySQL product version to install. Leave the defaults and select Ok and press Enter to install the repo.
Once the installation is done, you need to run system update to load package list.
apt updateInstall MySQL 8 on Debian 9
Now that you got MySQL APT repos in place, you can now install MySQL 8 by running the installation commands below;
apt install mysql-serverDuring the installation, you will be prompted to set MySQL root password. Hence, set the password and re-enter it when prompted.
Next, set the authentication plugin. Select the recommended option and proceed.

MySQL comes bundled with a security script called mysql_secure_installation that is used to improve MySQL installation security. The script can run with no options as shown below.
mysql_secure_installationSecuring the MySQL server deployment.
Enter password for user root: ENTER THE PASSWORD SET DURING THE INSTALLATIONNext, you are prompted whether to enable the validate password plugin that is used to enforce password complexity. Type Y and press Enter to enable or any other key to ignore.
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: YIf you accept to enable the validate password plugin, you will be prompted to choose the level of complexity, with three levels provided. Choose the level and press ENTER to proceed.
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: 1Next, you are prompted whether to reset or use existing root password.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : ENTER to retain existing passwordOnce the next prompts, press Y and enter to remove anonymous users, disallow remote root login, remove test databases and reload privileges tables to apply the changes.
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!MySQL 8 is now installed and running on Debian 9. You can check the version of MySQL as a way of verifying the installation. You can simply use mysqladmin to check the version instead of logging in running the select version query.
mysqladmin -u root -p version
Enter password:
