本地数据库：修改my.cnf (windows为my.ini)

[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'

rds:主要修改控制台上的参数参照charater-set-server
