使用的是Debain系統，安裝mysql發現已經默認的是mariadb,但是不管是使用linode官網說明還是百度搜索到的的根本安裝方法無法安裝成功。

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] y New password: Re-enter new password: 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] 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] 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] y- Dropping test database... ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist... Failed! Not critical, keep moving...- Removing privileges on test database......

If you've completed all of the above steps, your MariaDB installation should now be secure.Thanks for using MariaDB! root@debian:/etc/mysql/conf.d# mysql -uroot -proot Welcome to the MariaDB monitor.
