从RHEL / CentOS 7开始，MariaDB可用于两个操作系统的默认存储库。 所以我们可以简单地使用yum进行安装。 要安装它，请从终端执行以下命令，

$ yum install mariadb mariadb-server

一旦安装，我们将开始它的服务，并启用它，

$ systemctl start mariadb
$ systemctl enable mariadb

数据库现在正在运行，您可以通过运行登录到Mariadb

$ mysql

在终端。 root用户的默认密码默认为空白，你可以想象这是一个严重的安全威胁。 所以我们现在将确保我们的安装。

我们现在将通过在我们的终端中运行“mysql_secure_installation”来保护我们的MariaDB安装。 确保您仔细阅读程序的每一步，以确保安装，

$ mysql_secure_installation

/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

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.

Set root password? [Y/n] Y
New password: ROOTPASSWORD
Re-enter new password: ROOTPASSWORD
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] 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, yourMariaDB
installation should now be secure.

Thanks for using MariaDB!

就这样，我们的数据库现在是安全的，可以使用了。 我们现在可以通过使用登录到我们安装的MariaDB。

$ mysql –u root –p

可以继续创建新的数据库，表或用户。
