mysql5.7.9之后,就没有了password函数,所以,使用传统的password()函数修改root密码的话,就会提示sql错误
老版本修改命令(已不适用):
UPDATE user SET authentication_string = password('123456') WHERE User='root';
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 '('123456') WHERE User='root'' at line 1
正确设置密码的方法是:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
```bash
此时提示修改成功,退出mysql再次登陆即需要输入刚刚设置的密码。
