Php 与 MySQL 的连接问题(SQL STATE 2002),而连接字符串是正确的

Php Connection issue(SQL STATE 2002) with MySQL while connection string is right

我无法将架构更改从终端推送到 MySQL 数据库。

我总是收到 2002 错误。

我已经安装了MySQL。起来了 运行.

我正在使用 MAMP。

这是我的 .env 文件

# In all environments, the following files are loaded if they exist,
# the latter taking precedence over the former:
#
#  * .env                contains default values for the environment variables needed by the app
#  * .env.local          uncommitted file with local overrides
#  * .env.$APP_ENV       committed environment-specific defaults
#  * .env.$APP_ENV.local uncommitted environment-specific overrides
#
# Real environment variables win over .env files.
#
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
#
# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).

这是我的doctrine.yaml

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'
        mapping_types:
            enum: string       
#        unix_socket: /Applications/MAMP/tmp/mysql/mysql.sock

        # 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

为方便起见,下面我提到了 .env 文件中的连接字符串

 DATABASE_URL=mysql://sampleUserName:SamplePassword@127.0.0.1:3306/prod_cat?serverVersion=5.7

仅供参考:

如果 MySQL 的端口号与 连接字符串 中的内容 不匹配,这可能是一个问题。

通过访问 PhpMyAdmin 中的 MySQL 页面找到 MySQL 的端口号,并在您的连接字符串中使用端口号,或者使用 MySQL 的端口号MySQL 端口设置中的连接字符串。

更改 MySQL 端口。转到 MAMP 中的首选项并选择端口选项卡,您可以在那里更新它。
