连接到数据库Symfony 4 Flex

Question

我正在使用Symfony 4 Flex.I使用这个教程。这是我的数据库连接信息database_host: 127.0.0.1 database_user: root database_password: null

一开始我安装原则

composer require doctrine maker

然后设置我的数据库连接信息：

 parameters:
       env(DATABASE_URL): 'mysql://root:null@127.0.0.1:3306/sona'
    doctrine:
        dbal:
            driver: 'pdo_mysql'
            server_version: '5.7'
            charset: utf8mb4
            url: '%env(resolve:DATABASE_URL)%'
            url: '%env(resolve:DATABASE_URL)%'

当我执行

php bin/console   doctrine:database:create

我有这个错误

 In AbstractMySQLDriver.php line 103:

      An exception occured in driver: SQLSTATE[HY000] [1045] Access denied for user 'db_user'@'localhost' (using password: YES)


    In PDOConnection.php line 47:

      SQLSTATE[HY000] [1045] Access denied for user 'db_user'@'localhost' (using password: YES)


    In PDOConnection.php line 43:

      SQLSTATE[HY000] [1045] Access denied for user 'db_user'@'localhost' (using password: YES)


    doctrine:database:create [--shard SHARD] [--connection [CONNECTION]] [--if-not-exists] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction]
    [-e|--env ENV] [--no-debug] [--] <command>

我的错误在哪里？

Answer 1

对位于项目根目录中的.env文件进行更改。

Answer 2

请在.env文件中更新下面的配置，然后运行“php /控制台原则:数据库:创建”，这样它就会创建数据库。

# .env (or override DATABASE_URL in .env.local to avoid committing your changes)
# customize this line!
DATABASE_URL="mysql://db_user:db_password@127.0.0.1:3306/db_name"

# to use sqlite:
# DATABASE_URL="sqlite:///%kernel.project_dir%/var/app.db"
