Mariadb数据库，
Mariadb :数据库管理系统，属于Mysql的一个分支，完全兼容mysql。配置实验环境：将实验虚拟机重置
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0 ####配置网络
[root@localhost ~]# vim /etc/yum.repos.d/rhel_dvd.repo ###修改yum源指向
[root@localhost ~]# hostnamectl set-hostname mariadb.example.com ####修改主机名
-----------------------------mariadb的安装与使用------------------------
[root@mariadb ~]# yum clean all ####清除缓存的软件包

[root@mariadb ~]# mysql_secure_installation ###安全初始化
/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): #####回车
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 #####设置root用户密码
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 #####删除匿名用户
... 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 #####不允许远程用户登录
... 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 ######删除测试数据库
- 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 #####重新加载授权信息
... 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!
