Symfony 4 + Postgresql：即使我更改了doctrine.yaml和.env中的值，服务器仍然尝试连接到“ localhost”数据库

问题描述

我最近在一个运行该应用程序的虚拟机上部署了我的symfony应用程序，该虚拟机已连接到运行Postgresql服务器的主机。我正在尝试更改symfony应用程序中的数据库URL（我从将env中的DATABASE_URL更改为

pdo_pgsql://postgres:*password here*@192.168.122.1:5432/postgres?serverVersion=11&charset=utf8

但是，在服务器启动并访问页面时，出现错误：

      The Web server is using PHP CGI 7.3.21                                                                            
      http://127.0.0.1:8000

这清楚地表明，无论出于何种原因，Doctrine / PHP dba东西都试图连接到localhost：5432。我在网上查询过，提到的唯一文件是.env，doctrine.yaml和parameters.yml（我的项目结构中甚至没有）

我已经清除了两次缓存，但是大多数时候我尝试清除缓存时都会收到错误消息

[root@localhost dynamic_form_generator]# PHP bin/console cache:clear
*
 // Clearing the cache for the prod environment with debug false                                                        

 ! [NOTE] For better performances,you should move the cache and log directories to a non-shared folder of the VM.      


In Filesystem.PHP line 176:

所以我必须手动删除提到的目录，然后重试，此操作成功，但是在服务器运行时，它仍然表明服务器正在尝试运行到localhost：5432。我该怎么办？

这些是我上面提到的参数文件：

Doctrine.yaml ：（我将URL更改为“手写”值，因为我感到绝望，如果我拥有'％env（resolve：DATABASE_URL）％'，它也会执行相同的操作）

doctrine:

    dbal:
        driver: 'pdo_pgsql'
        charset: utf8
        url: pdo_pgsql://postgres:* password here *@127.0.0.1:5432/postgres?serverVersion=11&charset=utf8
        user:     "%env(resolve:DB_USERNAME)%"
        password: "%env(resolve:DB_PASSWORD)%"

        # IMPORTANT: You MUST configure your server version,# either here or in the DATABASE_URL env var (see .env file)
        #server_version: '5.7'
    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App
~

和.env ：（重要的部分，其余就是评论）

password *应该是密码所在的位置。我在做什么错了？

编辑：修复了粘贴文件内容中的小错误。

解决方法

整天搞乱配置后，我尝试运行 php bin/console debug:config doctrine | grep localhost来查看如果该学说覆盖了我的设置，那是什么问题，实际上似乎存在一个隐藏的参数“ host：localhost”。因此，我要做的就是返回到yaml文件，并添加“ host：192.168.122.1”行

所以看起来像这样：


    dbal:
        driver: 'pdo_pgsql'
        charset: utf8
        url: pdo_pgsql://postgres:* password here *@127.0.0.1:5432/postgres?serverVersion=11&charset=utf8
        user:     "%env(resolve:DB_USERNAME)%"
        password: "%env(resolve:DB_PASSWORD)%"
        host: 192.168.122.1

我希望这对任何有此问题的人都能解决！
