Php Symfony 4+；Postgresql:服务器仍在尝试连接到；“本地主机”；数据库，即使我更改了doctor.yaml和.env中的值

我最近在一台运行应用程序的虚拟机上部署了我的symfony应用程序，该虚拟机连接到我运行Postgresql server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中的数据库url更改为开始）

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某个页面时，我发现错误：

      The Web server is using PHP CGI 7.3.21

这清楚地表明，无论出于什么原因，Doctrine/PHP dba stuff都在尝试连接到localhost:5432。我在网上查过，提到的文件只有.env、Doctrine.yaml和parameters.yml（我的项目结构中甚至没有这些文件）

我已经清除了缓存两次，但大多数时候，当我试图清除它时，我得到了错误

[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.

• 这里的密码*是密码应该在的地方。我做错了什么

编辑：修复了粘贴文件内容中的小错误。

在对配置进行了一整天的混乱之后，我尝试运行

php-bin/console-debug:config-doctrine | grep localhost

查看如果该条令覆盖了我的设置，并且确实存在一个隐藏参数“host:localhost”，会出现什么问题。 所以我所要做的就是回到doctrine yaml文件，添加一行“host:192.168.122.1”

看起来是这样的：

    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

我希望这解决了任何人谁有它的问题
