Navicat connection MySQL8.0 test

 

 

I downloaded MySQL 8.0 today and found that Navicat could not connect, and always reported an error of 1251;

After trying many methods, I finally found one that can be achieved:

　　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: ******

　　After entering the root password again:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 18

mysql>

2. Change the 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 an error is reported:

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

　　then your remote access permissions are incorrect, via

select  user , host from  user ;

　　Check it out and change it 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 an error is reported:

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

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

mysql> use mysql;
Database changed
