Solution to failure in connecting to mysql in docker

Scenario: After installing the latest version of MySQL in the Docker container of the virtual machine, the following error appears when using Navicat to connect to MySQL in the virtual machine on the host machine:

2059 : Authentication plugin 'caching_sha2_password' cannot be loaded:

Solution:

1. First, use the docker ps command to check the running container to make sure that the mysql we want to connect to has been started. If it has not been started, use the docker start command to start it (the result in the figure below shows that a mysql has been started)

2. Then run docker exec -it b30062adc08c /bin/bash to enter the mysql container

3. Then enter the mysql -u root -p command, then enter your password, and finally enter the update password statement:

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

4. Finally, restart MySQL and use navicat to connect successfully.

Supplementary knowledge: Solution to the error of local remote connection to MySQL in Docker (1251)

The error is as follows:

Reason: MySQL 8.0 uses the caching_sha2_password authentication mechanism by default; the client does not support the new encryption method

Solution: Modify the encryption method of the user (root)

1. Enter the mysql container and enter in docker

docker exec -it mysql02 bash

2. Log in to MySQL

mysql -u root -p

As shown in the picture, enter 123456 and press Enter.

3. Set user configuration items

(1) View user information

select host,user,plugin,authentication_string from mysql.user;

(2) Modify the encryption method

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; //123456 is the login password of mysql

(3) Check user information again

select host,user,plugin,authentication_string from mysql.user;

(4) Use Navicate or other database software to connect again, success

(5) Supplement: If you want to exit normally without closing the container, you can exit the container by pressing Ctrl+P+Q

Exit the mysql container: Ctrl+D, press twice
