使用 MySQL8.0,发现Navicat连接不上,报错。
- 2059 - authentication plugin ‘caching_sha2_password’
- Operation ALTER USER failed for ‘root’@’%’
原因是MySQL8.0版本的加密方式和MySQL5.0的不一样,连接会报错。
试了很多种方法,终于找到一种可以实现的:
1.命令进入mysql窗口
C:\Users\Weijian>mysql -uroot -p
Enter password: ************
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 16

mysql>
2.更改加密方式:
第三方客户端连接不上mysql原因是mysql8.0更改了密码的存储方式,导致第三方链接不上。
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.20 sec)
更改密码
必须更改一次密码
mysql> alter user 'root'@'localhost' identified with mysql_native_password by 'WFCwfc123456';
Query OK, 0 rows affected (0.15 sec)
刷新
mysql> flush privileges;
Query OK, 0 rows affected (0.04 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:就是看一下当前数据库用户host是什么,对应下就可以了。
