mysql - 从主机网络的sql-client连接到docker容器时出错

Question

我正在使用撰写文件触发 mysql:

version: "3"
services:
  my-sql:
    image: mysql
    container_name: my-sql
    ports:
     - 3306:3306
    environment:
     MYSQL_ROOT_PASSWORD: passw0rd 
     MYSQL_USER: dbuser
     MYSQL_PASSWORD: pass1234
     MYSQL_DATABASE: connect_test

按以下方式查找容器的 IPAdress:

root@sevenos:~# docker inspect my-sql | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "172.18.0.2",

当我在容器外部连接my-sql client时，出现如下错误:

root@sevenos:~# mysql -uroot -ppassw0rd -h 172.18.0.2 -P 3306
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be 
loaded: /usr/lib/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

Answer 1

您可以使用以下命令初始化 docker 来加载默认身份验证插件:

mysql:
    image: mysql
    container_name: mysql
    command: mysqld --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
        - MYSQL_ROOT_PASSWORD=root
    volumes_from:
        - mysql-data
    ports:
        - "3306:3306"

在运行它之前，您必须删除所有 mysql 卷:

docker-compose rm
docker volume rm list_of_your_volumes
docker-compose up
