+# 20240324102510 MySQL MariaDBのインストール
+#raspi #mysql #server #MariaDB
+
+MariaDBはMySQLのforkで、互換性もあり性能も向上しているとのこと。現状(20240324)ではMariaDBを使用した方がよいかもしれない。そもそもraspberry pi OS には`mysql-server`のパッケージが存在していない。
+
+```
+$ sudo apt install mariadb-server
+$ sudo mysql_secure_installation
+```
+
+```
+$ sudo mysql_secure_installation
+
+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
+haven't set the root password yet, you should just press enter here.
+
+Enter current password for root (enter for none):[Enter]
+OK, successfully used password, moving on...
+
+Setting the root password or using the unix_socket ensures that nobody
+can log into the MariaDB root user without the proper authorisation.
+
+You already have your root account protected, so you can safely answer 'n'.
+
+Switch to unix_socket authentication [Y/n] n
+ ... skipping.
+
+You already have your root account protected, so you can safely answer 'n'.
+
+Change the root password? [Y/n] [Enter]
+New password:[パスワード入力]
+Re-enter new password:[パスワード入力]
+Password updated successfully!
+Reloading privilege tables..
+ ... Success!
+
+
+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] [Enter]
+ ... 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] [n]
+ ... skipping.
+
+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] [Enter]
+ - 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] [Enter]
+ ... 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!

+$ grant all privileges on *.* to root@"%" identified by '****' with grant option;
+$ sudo systemctl restart mysql
