3、设置开机启动

systemctl enable mariadb

4、初始化 Mariadb，设置密码

5、配置Mariadb字符集

 5.1、配置 /etc/my.cnf 文件，在[mysqld]标签下添加如下：

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

5.2、配置 /etc/my.cnf.d/client.cnf 文件，在[client]中添加如下：

default-character-set=utf8

5.3、配置 /etc/my.cnf.d/mysql-clients.cnf 文件，在[mysql]中添加如下：

default-character-set=utf8

6、重启 Mariadb

systemctl restart mairadb

7、登录 Mariadb 查看字符集是否设置成功

MariaDB [(none)]> show variables like "%character%";show variables like "%collation%";

显示为如下：
