在CentOS 6上安装MariaDB 10

• 添加MariaDB存储库
• 安装软件
• 安全的MariaDB

在撰写本文时，MariaDB 10.1是MariaDB的开发版本。它基于MariaDB 5.5，并包含MySQL 5.6的反向移植功能。还有一些MariaDB独有的新功能。

对于CentOS，RedHat和Fedora，强烈建议使用yum从存储库安装。本指南将引导您完成CentOS 6的安装步骤。

添加MariaDB存储库

首先，在安装之前，请确保可用软件包的列表是最新的。打开SSH终端并输入以下命令。

yum -y update

添加MariaDB存储库。

nano /etc/yum.repos.d/MariaDB.repo

对于32位用户，请粘贴以下文本：

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos6-x86
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

对于64位用户，请粘贴以下文本：

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

保存MariaDB.repo文件。

安装软件

此时，安装MariaDB就像只运行一个命令一样简单。

yum install MariaDB-server MariaDB-client -y

安装完成后，启动MariaDB。

service mysql start

接下来，将MariaDB设置为在每次引导时启动。

chkconfig mysql on

安全的MariaDB

保护您的MariaDB安装。以下清单显示了将要执行的步骤。

• 设置（更改）根密码。
• 删除匿名用户。
• 禁止远程root登录。
• 删除测试数据库并访问它。
• 重新加载特权表。

运行安全安装命令。

mysql_secure_installation

输出示例

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: ENTER YOUR PASSWORD
Re-enter new password: REPEAT YOUR 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] 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!

重新启动MariaDB。

service mysql restart

您可以使用以下命令连接到MariaDB。

mysql -u root -p

恭喜，您已在CentOS 6上成功安装了MariaDB。
