- 5.資料庫管理
-- 建立賬號、分配許可權
CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'user'@'localhost' WITH GRANT OPTION
-- 修改密碼，使資料庫可以連線Navicat
ALTER USER 'user'@'%' IDENTIFIED WITH mysql_native_password BY 'password';
-- 重新整理許可權
FLUSH PRIVILEGES;
-- 顯示賬號及許可權相關資訊
SHOW GRANTS FOR 'user'@'localhost';
