Navicat連接MySQL8.0 2059 - authentication plugin

使用 MySQL8.0，發現Navicat連接不上，報錯。

• 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的不一樣，連接會報錯。

試了很多種方法，終於找到一種可以實現的：

1.命令進入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
Server version: 8.0.18 MySQL Community Server - GPL

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

2.更改加密方式：

第三方客戶端連接不上mysql原因是mysql8.0更改了密碼的存儲方式，導致第三方鏈接不上。

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.20 sec)

更改密碼

必須更改一次密碼

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)

如果報錯 ERROR 1396 (HY000): Operation ALTER USER failed for ‘root’@’%’ ：
則是遠程訪問權限不正確，先選擇數據庫，查看一下再更改：就是看一下當前數據庫用戶host是什麼，對應下就可以了。
