mysql创建新用户出现错误处理

心血来潮创建一个新用户，结果。。。步步艰难啊，好在最后成功，把我出现的问题和解决方案抛出来，希望大家顺顺利利创建成功┗|｀O′|┛ 嗷~~

我出现的错误主要有这三种：

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

解决办法：

1、找到mysql安装目录下的bin文件夹

2.cmd转到该目录下

C:Program FilesMySQLMySQL Server 8.0in>

3、登录：（输入密码）

C:Program FilesMySQLMySQL Server 8.0in>mysql -uroot -p
Enter password: ********

4、开始创建用户，并授予权限

mysql> use mysql;
Database changed
mysql> delete from user where user='gao'; #用常规方式删除一遍，防止之前建立了隐藏用户导致的无法创建成功
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';#开始创建用户
Query OK, 0 rows affected (0.09 sec)

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

mysql> quit
Bye

5、退出并重新登录即可
