更改加密方式
1.先通过命令行进入mysql的root账户：
ps c:\windows\system32> mysql -uroot -p
再输入root的密码：
enter password: ******welcome to the mysql monitor. commands end with ; or \g.your mysql connection id is 18server version: 8.0.11 mysql community server - gplcopyright (c) 2000, 2018, oracle and/or its affiliates. all rights reserved.oracle is a registered trademark of oracle corporation and/or itsaffiliates. other names may be trademarks of their respectiveowners.type 'help;' or '\h' for help. type '\c' to clear the current input statement.mysql>
2.更改加密方式：
mysql> alter user 'root'@'localhost' identified by 'password' password expire never;query ok, 0 rows affected (0.10 sec)
3.更改密码：
mysql> alter user 'root'@'localhost' identified with mysql_native_password by 'password';query ok, 0 rows affected (0.35 sec)
4.刷新：
mysql> flush privileges;query ok, 0 rows affected (0.28 sec)
// 如果报错 error 1396 (hy000): operation alter user failed for 'root'@'%' ：
则是远程访问权限不正确，先选择数据库，查看一下再更改：
mysql> use mysql;database changedmysql> select user,host from user;+------------------+-----------+| user | host |+------------------+-----------+| mysql.infoschema | localhost || mysql.session | localhost || mysql.sys | localhost || root | localhost |+------------------+-----------+5 rows in set (0.00 sec)
