配置MariaDB数据库的字符集

1.编辑文件/etc/my.cnf, 在[mysqld]标签下添加内容如下:

[root@localhost ~]# vi /etc/my.cnf

[mysqld]
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

2.编辑文件/etc/my.cnf.d/client.cnf, 在[client]中添加内容如下:

[root@localhost ~]# vi /etc/my.cnf.d/client.cnf

[client]
default-character-set=utf8

3.编辑文件/etc/my.cnf.d/mysql-clients.cnf, 在[mysql]中添加内容如下:

[root@localhost ~]# vi /etc/my.cnf.d/mysql-clients.cnf

[mysql]
default-character-set=utf8

4.全部配置完成, 重启mariadb

systemctl restart mariadb

5.进入MariaDB查看字符集
