其他配置

Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车

Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,

Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车

Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车

初始化MariaDB完成，接下来测试登录

mysql -uroot -ppassword

[root@localhost ~]# 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
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:
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]
... 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]
- 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]
... 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!

2、配置MariaDB的字符集

文件/etc/my.cnf

vi /etc/my.cnf

在[mysqld]标签下添加

init_connect=‘SET collation_connection = utf8_unicode_ci‘ 
init_connect=‘SET NAMES utf8‘ 
character-set-server=utf8 
collation-server=utf8_unicode_ci 
skip-character-set-client-handshake

文件/etc/my.cnf.d/client.cnf

vi /etc/my.cnf.d/client.cnf

在[client]中添加

default-character-set=utf8

文件/etc/my.cnf.d/mysql-clients.cnf

vi /etc/my.cnf.d/mysql-clients.cnf

在[mysql]中添加

default-character-set=utf8

 全部配置完成，重启mariadb

systemctl restart mariadb

之后进入MariaDB查看字符集

[root@localhost ~]# mysql -u root -p
Enter password:
