mysql 更改資料庫編碼utf8到utf8mb4
修改my.cnf 以下內容
[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-server = utf8mb4 ###不能只加這一行,不然會連不上SERVER
collation-server = utf8mb4_unicode_ci
重新啟動MYSQL
service mysql restart
進入下mysql
mysql -uroot -p
mysql>show variables like '%character%';
