Authentication plugin 'caching_sha2_password' cannot be loaded

Question

I am connecting MySQL - 8.0 with MySQL Workbench and getting the below error:

Authentication plugin \'caching_sha2_password\' cannot be loaded: dlop

Answer 1

Downloading a development release of 8.0.11-rc worked for me on a mac. with the following docker commands:

docker run --name mysql -p 3406:3306 -e MYSQL_ROOT_PASSWORD=mypassword -d mysql

Answer 2

you can change the encryption of the password like this.

ALTER USER 'yourusername'@'localhost' IDENTIFIED WITH mysql_native_password BY 'youpassword';

Answer 3

I had the same problem, but the answer by Aman Aggarwal didn't work for me with a Docker container running mysql 8.X. I loged in the container

docker exec -it CONTAINER_ID bash

then log into mysql as root

mysql --user=root --password

Enter the password for root (Default is 'root') Finally Run:

ALTER USER 'username' IDENTIFIED WITH mysql_native_password BY 'password';

You're all set.

Answer 4

This is my databdase definition in my docker-compose:

dataBase:
    image: mysql:8.0
    volumes:
        - db_data:/var/lib/mysql
    networks:
        z-net:
            ipv4_address: 172.26.0.2
    restart: always
    entrypoint: ['docker-entrypoint.sh', '--default-authentication-plugin=mysql_native_password']
    environment:
        MYSQL_ROOT_PASSWORD: supersecret
        MYSQL_DATABASE: zdb
        MYSQL_USER: zuser
        MYSQL_PASSWORD: zpass
    ports:
        - "3333:3306"

The relevant line there is entrypoint.

After build and up it, you can test it with:

$ mysql -u zuser -pzpass --host=172.26.0.2  zdb -e "select 1;"
Warning: Using a password on the command line interface can be insecure.

Answer 5

Currently (on 2018/04/23), you need to download a development release. The GA ones do not work.

I was not able to connect with the latest GA version (6.3.10).

It worked with mysql-workbench-community-8.0.11-rc-winx64.msi (from https://dev.mysql.com/downloads/workbench/, tab Development Releases).

Answer 6

like this?

docker run -p 3306:3306 -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d mysql --default-authentication-plugin=mysql_native_password
mysql -uroot --protocol tcp

Try in PWD

https://github.com/GitHub30/docs/blob/change-default_authentication_plugin/mysql/stack.yml

or You shoud use MySQL Workbench 8.0.11.
