问题描述：

mysql出现ncorrect string value: '\xF0\x9F...' for column 'XXX' at row 1

1、修改数据库的编码为utf8bm4

# vi /etc/my.cnf

[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'

重启服务

systemctl restart mysqld.service 

2、修改数据表的编码为utf8bm4

mysql> ALTER DATABASE DBNAME CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

mysql> ALTER TABLE TBNAME CONVERT to CHARACTER SET utf8mb4 COLLATE utf8mb4_bin; 

3、修改连接数据库的连接代码
