Mysql-8 執行授權語句錯誤：ERROR 1064 (42000)

今天在mysql執行授權語句

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password'WITH GRANT OPTION;

時提示如下錯誤：

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'Tibco123'WITH GRANT OPTION' at line 1、

意識到版本問題后就百度mysql-8授權語句的語法，終於解決問題。

在Mysql 8版本中，不能使用 

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password'WITH GRANT OPTION;

這一行命令來設置用戶權限，必須分兩步來實現設置用戶權限【先創建用戶、在對該用戶分配用戶權限】，最后刷新權限

mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
