Install MySQL on your raspberry pi
This guide is very short and only takes 2 commands to install MySQL on your pi (if your pi is up to date).
Looking for an install tutorial for Windows? Click here
Things you need before we start
- Raspberry Pi (setting one up can be done this way)
- A few minutes of your day :)
Make sure your pi is up to date!
Run these two commands to insure you have the latest OS updates:
sudo apt-get update; sudo apt-get upgrade
This may take a few minutes, but needs to be done in order to pull down the latest install for MySQL.
sudo apt-get install mysql-server
You will be prompted to type the letter 'Y' in order to install. Once you type 'Y' and hit enter MySQL will be installed very quickly.
It's installed, now what? SECURITY!
Let's make sure we don't let the bad guys win. Below I have provided the answers to the questions that this next command will ask you. Choose what you want if you know what you are doing or simply follow the answers I provided for my instance.
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have a root password set, so you can safely answer 'n'. Change the root password? [Y/n] n ... skipping. By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] 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? [Y/n] y ... Success! By default, MariaDB 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? [Y/n] 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? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
Create your first database!
In the future I will put up more MySQL tutorial/guides in the MySQL section. For now, I will show you how to create a database.
pi@tyrion:~ $ sudo mysql -u root -p Enter password:
