修改配置檔案 my.conf

如沒有[client] [mysql] [mysqld]需手動新增

[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'

重啟

service mysql restart
