Navicat connection MySQL 8.0 pro test

Today, the next MySQL 8.0 found that Navicat could not connect, and always reported 1251 errors;

After trying many ways, we finally found a way to achieve it:

By changing the encryption method:

 

1. First enter the root account of mysql through the command line:

 

PS C:\Windows\system32> mysql -uroot -p
Enter password: ******

Enter the password of root again:

Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql>

2. Change encryption method:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.10 sec)

3. Change the password again:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Query OK, 0 rows affected (0.35 sec)

4. refresh:

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.28 sec)

//If error 1396:

ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'%'

The remote access permission is incorrect. Check it and change it again, as follows:

mysql> 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)

//If error 1046:

mysql> select user,host from user;
ERROR 1046 (3D000): No database selected

Select the database first, and then run "select user,host from user;" to view:

mysql> use mysql;
Database changed
