docker撰写MySQL容器[2002]连接被拒绝 [英] docker compose MySQL container [2002] Connection refused

问题描述

我正在尝试为Nginx + PHP(Laravel)+ MySQL构建docker compose容器，但我一直收到连接被拒绝的错误消息

I'm trying to build docker compose containers for Nginx + PHP(Laravel) + MySQL, but I keep getting Connection refused error

docker-compose.yml

version: "3"
services:

    nginx:
        image: nginx:latest
        ports:
            - '8080:80'
        volumes:
            - ./nginx:/etc/nginx/conf.d
            - ./logs/nginx:/var/logs/nginx
            - ./apps:/var/www/html
        depends_on:
            - php
        restart: always

    php:
        image: laradock/php-fpm:2.2-7.2
        volumes:
            - ./apps:/var/www/html
        restart: always
    mysql:
        image: mariadb
        ports:
            - '33060:3306'
        volumes:
            - ./db:/var/lib/mysql
        environment:
            - MYSQL_ROOT_PASSWORD=root
        restart: always

在 ./apps 中，我有一个带有基本SQL设置的全新Laravel应用

In ./apps I have a brand new Laravel app with basic SQL setup

所有容器运行都没有错误，我可以使用以下方式连接到MySQL容器

All containers run without errors, and I can connect to the MySQL container using

mysql -u 127.0.0.1 -P 33060 -u root -p

但是当我尝试从浏览器访问或将ssh直接导入php容器时，我仍然收到错误2002.

but I keep getting error 2002 when I try to access from the browser or direct ssh into php container.

我在服务器上运行了nginx和mysql，所以我使用8080和33060端口，不确定是否是问题所在.

I have nginx and mysql running on the server so I use 8080 and 33060 port, not sure if that's the problem.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=root
DB_PASSWORD=secret

感谢您的帮助.

我的第一个猜测是试图找到mysql unix快死了套接字文件，需要通过非本地主机进行连接时联系.如果您使用撰写文件启动它们，则您可以连接到docker提供的dns名称(即，链接:docker-mysql，将dns名称设置为docker-mysql).所以你必须更改您的连接线:

My first guess is that it is dying trying to find the mysql unix socket file, when it needs to be connecting over a non-localhost connection. If you are using the compose file to start them, then you can connect to the dns name provided by docker (ie, links: docker-mysql, sets the dns name to be docker-mysql). So you have to change your connection line:

-php -r新的PDO('mysql:host = localhost; port = 3306; charset = utf8'，'root'，'123123');'

+ php -r新的PDO('mysql:host = docker-mysql; port = 3306; charset = utf8'，'root'，'123123');'

通过将 DB_HOST 更改为 .env 文件

DB_HOST=docker_mysql_1
