php artisan migrate错误:提供或不知道节点名或服务名

问题描述

我的 laradock 项目遇到了麻烦:我已经下载并安装了 docker，并且我已经使用 laradock 成功完成了我的 laravel 项目的设置.我使用 php 7、laravel(5.5.14) 和最新版本的 laradock.我开始在 shell 中编写我的项目:

I'm in trouble with my laradock project: i have downloaded and installed docker and i have successfully completed the setup of my laravel project with laradock. I use php 7, laravel(5.5.14) and the latest version of laradock. I start my project writing in shell:

docker-compose up -d nginx mysql

然后所有服务都启动了.我的 env 文件是:

and all services starts. My env file is:

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

但是当我尝试将迁移与

But when i try to use the migration with

php artisan migrate

我收到此错误:

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known (SQL: select * from information_schema.tables where table_schema = homestead and table_name = migrations) 
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known 
PDO::__construct(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known 

我的名为 homestead 的数据库已创建并且可以正常工作.在我的 Laravel 项目中，在迁移文件夹下我有 3 个文件 php:create_user_table、create_password_reset_table 和 create_customer_table(我写了这个文件).我需要在我的数据库中创建一个名为 customer 的表，其中包含一些列:

My db called homestead is created and it works. In my laravel project, under the migration folder i have 3 files php: create_user_table, create_password_reset_table and create_customer_table( i have wrote this file). I need to create a table in my db called customer with some colums:

Schema::create('customers', function (Blueprint $table) {
        $table->increments('id');
        $table->string('first_name');
        $table->string('last_name');
        $table->boolean('azienda');
        $table->string('iva');
        $table->string('ds');
        $table->boolean('fatres');
        $table->string('cf');
        $table->string('mail');
        $table->string('telefono');
        $table->integer('sponsor');
        $table->string('indinst');
        $table->string('civinst');
        $table->string('cityInst');
        $table->string('capinst');
        $table->string('provinst');
        $table->string('indf');
        $table->string('civf');
        $table->string('capf');
        $table->string('provf');
        $table->string('cityFatt');
        $table->timestamps();
    });

如何完成迁移并创建表?谢谢解答！

@Stefano Zaniboni 在评论中回答了这个问题，但要扩展:

@Stefano Zaniboni answered this in a comment but to expand:

我遇到这个问题是因为我习惯于在本地目录而不是在 virtualbox/vagrant box/docker 容器中运行 php artisan 命令.

I ran across this issue because I'm used to running php artisan commands in my local directory rather than in a virtualbox / vagrant box / docker container.

Laravel Docs 提到您需要运行 phpartisan migrate 命令从你的虚拟机中.

The Laravel Docs mention that you need to run the php artisan migrate command from within your virtual machine.

如果您使用 docker，则可以使用 docker ps 获取容器 ID.然后使用 docker exec -it ssh 进入容器./bin/bash.然后只需 cd 进入您的项目目录并运行 php artisan migrate.

If you're using docker, you can get your container id using docker ps. Then to ssh into the container use docker exec -it <containerId> /bin/bash. Then just cd into your project directory and run php artisan migrate.
