# 步骤
- 打开mysql配置文件`vim /etc/my.cnf`
- 末端插入以下配置

```
[client]
default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4

[mysqld]
character-set-client-handshake=FALSE
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
```

- 保存退出`:wq`
- 重启mysql`/usr/local/mysql/bin/mysqld restart`
- 更改表结构
`ALTER TABLE t_dynamic CONVERT TO CHARACTER SET utf8mb4;`

OK，可以保存了！
