mysql支持发表情简单设置

1. 修改my.cnf

[mysqld]

character-set-server=utf8mb4

[mysql]

default-character-set=utf8mb4

修改后重启Mysql

 

2. 以root身份登录Mysql，修改环境变量，将character_set_client,character_set_connection,character_set_database,character_set_results,character_set_server 都修改成utf8mb4

 set character_set_client = utf8mb4;

 set character_set_connection = utf8mb4; 

 set character_set_database = utf8mb4; 

 set character_set_results = utf8mb4; 

 set character_set_server = utf8mb4; 

 character-set-server=utf8mb4 

 set names utf8mb4

 show variables like 'character%';

 

3. 将已经建好的表也转换成utf8mb4

命令：alter table TABLE_NAME convert to character set utf8mb4 collate utf8mb4_bin; （将TABLE_NAME替换成你的表名）
