I had the same issue. I have cloned the L5.1 project from GIT and i performed

我遇到过同样的问题。我已经从 GIT 克隆了 L5.1 项目并且我执行了

composer install 
composer update 

and also configured DB details in .env (by default .env is not present so i took the copy of .env.example and renamed as .env). After that if tried to run

并且还在 .env 中配置了数据库详细信息（默认情况下 .env 不存在，所以我获取了 .env.example 的副本并重命名为 .env）。之后，如果尝试运行

 php artisan migrate

I got the same exception like as @users4393829 mentioned. I tried follow commands to find and set the database.

我遇到了与@users4393829 提到的相同的异常。我尝试按照命令来查找和设置数据库。

 php artisan tinker
 >>> Config::get('database.connections.mysql.database');
 >>>null
 >>>Config::set('database.connections.mysql.database','homesteaed');
 >>>Config::get('database.connections.mysql.database');
 >>>homesteaed

After doing all this things i found that there is no database.php file so i have placed it in the 'config' folder and ran the migration it works. Please make sure that you have any config files is git ignored in your project.

完成所有这些事情后，我发现没有 database.php 文件，所以我将它放在“config”文件夹中并运行了它的迁移。请确保您有任何配置文件在您的项目中被 git 忽略。

I had the same problem, turns out the .envthat shipped with the framework defaulted the DB_HOSTto localhostand had DB_PORT set.

我遇到了同样的问题，结果.env是框架附带的默认设置DB_HOST为localhost并设置了 DB_PORT。

Changed the host to the FQDN of the machine and it worked fine. I'm guessingif you're connecting to localhostit expects a socket and not a port.

将主机更改为机器的 FQDN，它工作正常。我猜如果你连接到localhost它需要一个套接字而不是一个端口。
