MySQL

Proven on:

11 (bullseye)

As always...

Start with:

• sudo apt update
• sudo apt upgrade

MySQL on Debian

Debian does not have MySQL in its repositories... :(

We can solve this!

Check the MySQL download page for current version...

If you're happy with 8.0.28, go ahead, download & install.

(Do note: apt update may throw errors if you don't use the latest version.)

• wget https://dev.mysql.com/get/mysql-apt-config_0.8.22-1_all.deb
• sudo apt install ./mysql-apt-config_0.8.22-1_all.deb

It may ask about distro version. On LMDE 4 or SparkyLinux 5, Select "debian buster" (It won't ask on Debian...)

Select "Ok"

Select "Ok"

Select "Ok"

Some versions will also ask about Configuring mysql-community-server

• Pick a good root password...
• I tend to select Use Legacy Authentication Method because Use Strong Password Encryption is annoying as hell. (Your choice here...)

Update & Upgrade everything now...

• sudo apt update
• sudo apt upgrade

Now you can go ahead & pretend they haven't dropped MySQL from the Debian repos...

Now Do A Backup!

Configure MySQL

• sudo mysql_secure_installation
  • Would you like to setup VALIDATE PASSWORD component?
    • I select No (because I'd rather manage my own password policies, thanks...)
  • root password
    • Please set the password for root here.
      • Pick a good root password...
  • or... (depends on install...)
    • Using existing password for root.
      • Say No (Which actually means yes... The question being asked is "Change the password for root?")
  • Remove anonymous users?
    • Duh... Yes
  • Disallow root login remotely?
    • Your choice, but I tend to say No.
  • Remove test database and access to it?
    • Duh... Yes again.
  • Reload privilege tables now?
    • Yes
• (Extra Instructions if you've never configured MySQL before)

Now Do A Backup!

Set up at least one user in mysql

• sudo mysql -u root -p

CREATE USER 'USERNAME'@'localhost' IDENTIFIED BY 'PASSWORD';
FLUSH PRIVILEGES;
EXIT;

(Hint: This'd be a good time to create yourself as that user with your non-admin password of choice...)

If this is a Database server, you'll be doing the same again but replacing localhost with MachineName (where MachineName is the name of any remote machines that need access to your databases).
