1. yum安裝mysql資料庫

[root@localhost ~]# yum -y install mariadb mariadb-server

2.修改mysql資料庫的配置檔案

配置檔案的位置 /etc/my.cnf

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

設定伺服器端
在 [mysqld] 下新增

character-set-server=utf8

新建[client]，新增

default-character-set=utf8

修改後如圖：

3.重啟MySQL服務

[root@localhost ~]# systemctl restart mariadb
 

4.進入mysql檢視

預設已支援中文

[root@localhost ~]# mysql

5.建立庫和表測試

MariaDB [(none)]> create database wg;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> use wg;
Database changed

MariaDB [wg]> create table student(id int,name varchar(20));
Query OK, 0 rows affected (0.01 sec)

MariaDB [wg]> insert into student values(1,'冬天');
Query OK, 1 row affected (0.00 sec)

MariaDB [wg]> select * from student;
+------+--------+
| id   | name   |
+------+--------+
|    1 | 冬天   |
