mysql創建新用戶出現錯誤處理

心血來潮創建一個新用戶，結果。。。步步艱難啊，好在最后成功，把我出現的問題和解決方案拋出來，希望大家順順利利創建成功┗|｀O′|┛ 嗷~~

我出現的錯誤主要有這三種：

1、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 'indentified by '1998'' at line 1

2、ERROR 1396 (HY000): Operation CREATE USER failed for 'gaohan1'@'localhost'

3、ERROR 1410 (42000): You are not allowed to create a user with GRANT

解決辦法：

1、找到mysql安裝目錄下的bin文件夾

2.cmd轉到該目錄下

C:\Program Files\MySQL\MySQL Server 8.0\bin>

3、登錄：（輸入密碼）

C:\Program Files\MySQL\MySQL Server 8.0\bin>mysql -uroot -p
Enter password: ********

4、開始創建用戶，並授予權限

mysql> use mysql;
Database changed
mysql> delete from user where user='gao'; #用常規方式刪除一遍，防止之前建立了隱藏用戶導致的無法創建成功
Query OK, 1 row affected (0.30 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.04 sec)

mysql> create user gao@localhost identified by '1998';#開始創建用戶
Query OK, 0 rows affected (0.09 sec)

mysql> flush privileges;#刷新權利
Query OK, 0 rows affected (0.04 sec)

mysql> quit
Bye

5、退出並重新登錄即可
