Symfony3-SQLSTATE [HY000] [2002]没有这样的文件或目录

问题描述

我不熟悉Symfony，并开始做一些教程以完成一些工作.我正在使用Linux Mint 18机器和标准的Symfony3-project.

I am new to Symfony and started doing some tutorials in order to get some things done. I am working on a Linux Mint 18 machine and a standard Symfony3-project.

我想创建一个简单的数据库来使用它，但是遇到一个错误，找不到适合的解决方案.

I'd like to create a simple database to play around with it, but I am encountering an error I can't find the right solution for.

我的parameters.yml文件如下:

My parameters.yml file looks like this:

parameters:
   database_host: localhost
   database_port: null
   database_name: symfony
   database_user: root
   database_password: null
   mailer_transport: smtp
   mailer_host: 127.0.0.1
   mailer_user: null
   mailer_password: null
   secret: (not relevant)

我的Genus.php文件如下所示:

My Genus.php file looks like this:

namespace AppBundle\Genus;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="genus")
 */
class Genus
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    private $id;
    /**
     * @ORM\Column(type="string")
     */
    private $name;

}

当我执行命令 dpkg -l php * mysql 时，我得到以下结果:

When I execute the command dpkg -l php*mysql I get the following result:

dpkg -l php*mysql
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

un  php7.0-pdo-mysql  <none>        <none>        (no description available)

当我尝试使用命令提示符使用创建本地数据库时

When I try to create a local database using the command prompt using

XXX@XXX-pc ~/PhpstormProjects/test_symfony $ php bin/console doctrine:database:create

这就是我得到的:

我遇到了许多其他话题，但是找不到正确的答案.谁能告诉我我在这里想念的东西吗?任何帮助都非常感激:)

I've came across many other topics but wasn't able to find the right answer. Could anyone tell me what I am missing here? Any help is much appreciated :)

推荐答案

在我的情况下，我仅更改了localhost-> 127.0.0.1即可正常工作！

In my case, I only changed localhost->127.0.0.1 and it worked!
