当一台机器上的多个Laravel项目或laravel无法读取.env文件时，冲突数据库 [英] Conflict database when Multiple Laravel Projects on single machine or laravel not reading .env file

问题描述

我在Windows 10上使用xampp.我在这台机器上有多个laravel 5.2项目.当我执行Project 1时，它给我一个错误，提示database_project_1.table_of_project_2表或视图不存在，但database_project_2中存在表table_of_project_2.这个问题很少出现.

I am using xampp on windows 10. I have multiple laravel 5.2 projects on this machine. When I am executing Project 1 it gives me the error that database_project_1.table_of_project_2 table or view do not exist, but the table table_of_project_2 is existing in the database_project_2. This issue comes rarely.

下面是项目1 .env文件

APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:ratSluNv930gb3wp1UOabW6Ze3jEJn3ixtTX/wgqYZc=
APP_URL=http://project-1.dev/

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_project_1
DB_USERNAME=root
DB_PASSWORD=j@yshr33r@m

下面是 Project 2 .env文件

APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:XRgQHfYiKPmHtHZ5UbX38KDlBnl/nyBSt+8qnkOISTg=
APP_URL=http://project-2.dev/

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_project_2
DB_USERNAME=root
DB_PASSWORD=j@yshr33r@m

我尝试了以下命令，但是没有运气:

I have tried below commands but with no luck:

1. php artisan config:clear
2. php artisan cache:clear

1. php artisan config:clear
2. php artisan cache:clear

请检查以下屏幕截图:

Please check the screenshot below:

请让我知道是否缺少任何东西.

Please let me know if any thing is missing.

这是两个项目的config/database.php代码.

Here is the config/database.php code for both projects.

项目1 config/database.php

Project 1 config/database.php

<?php

return [
    'fetch' => PDO::FETCH_CLASS,
    'default' => env('DB_CONNECTION', 'mysql'),
    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'database_project_1'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', 'j@yshr33r@m'),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],

    ],
    'migrations' => 'migrations',
    'redis' => [
        'cluster' => false,
        'default' => [
            'host' => env('REDIS_HOST', 'localhost'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', 6379),
            'database' => 0,
        ],
    ],
];

项目2 config/database.php

Project 2 config/database.php

<?php

return [
    'fetch' => PDO::FETCH_CLASS,
    'default' => env('DB_CONNECTION', 'mysql'),
    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'database_project_2'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', 'j@yshr33r@m'),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],

    ],
    'migrations' => 'migrations',
    'redis' => [
        'cluster' => false,
        'default' => [
            'host' => env('REDIS_HOST', 'localhost'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', 6379),
            'database' => 0,
        ],
    ],
];

看看代码，让我知道所需的内容.

Take a look at the code and let me know anything required.

读取.env文件或与另一个项目的.env文件冲突是否有问题?

Is it problem with reading .env file or conflicting .envfile of another project?

推荐答案

您已指定在Project 2的config/database.php中使用database_project_1:

You have specified to use database_project_1 in Project 2's config/database.php:

'database' => env('DB_DATABASE', 'database_project_1'),

因此，如果env('DB_DATABASE')不返回任何值，则将使用默认值database_project_1.如缓存在SO上的几个问题所述，这可能取决于缓存:示例1 ，示例2 ，

So if ever env('DB_DATABASE') does not return a value , the default of database_project_1 will be used. That can happen depending on caching, as described in a few questions here on SO: example 1, example 2, example 3.

如果这是一个缓存问题，您可以尝试通过以下几种组合(安装和版本之间的差异)来解决此问题:

If it is a caching issue, you can try to fix that by some combination of the following (varies between installs and versions):

php artisan config:clear
php artisan cache:clear
composer dump-autoload
// restart your web server

但最简单的解决方法肯定是在Project 2 config/database.php中使用正确的默认值:

But surely the simplest fix would be to just use the correct default value in your Project 2 config/database.php:

'database' => env('DB_DATABASE', 'database_project_2'),
