CakePHP 4.0 数据库配置

Question

    'default' => [
        'className' => Connection::class,
        'driver' => Mysql::class,
        'persistent' => false,

        'username' => 'root',
        'password' => 'root',
        'port' => '8889',

        'database' => 'rajasthan_skill_development',
        'timezone' => 'UTC',

        /**
         * For MariaDB/MySQL the internal default changed from utf8 to utf8mb4, aka full utf-8 support, in CakePHP 3.6
         */
        //'encoding' => 'utf8mb4',

        /**
         * If your MySQL server is configured with `skip-character-set-client-handshake`
         * then you MUST use the `flags` config to set your charset encoding.
         * For e.g. `'flags' => [\PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8mb4']`
         */
        'flags' => [],
        'cacheMetadata' => true,
        'log' => false,

        /*
         * Set identifier quoting to true if you are using reserved words or
         * special characters in your table or column names. Enabling this
         * setting will result in queries built using the Query Builder having
         * identifiers quoted when creating SQL. It should be noted that this
         * decreases performance because each query needs to be traversed and
         * manipulated before being executed.
         */
        'quoteIdentifiers' => false,

        /*
         * During development, if using MySQL < 5.6, uncommenting the
         * following line could boost the speed at which schema metadata is
         * fetched from the database. It can also be set directly with the
         * mysql configuration directive 'innodb_stats_on_metadata = 0'
         * which is the recommended value in production environments
         */
        //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
    ],

上面的代码 config/app.php 文件所在的位置，以便使用 MySQL 启用数据库我无法加载数据库并使用该配置连接 MySQL 数据库我在哪里找到你问的错误：

error file 
/Applications/MAMP/htdocs/sd/sd/vendor/cakephp/cakephp/src/Database/Driver.php

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

我想利用那个错误找到解决错误的方法。感谢所有帮助。烘烤！

Answer 1

app.php中的设置可以说是default/global设置，可以通过加载额外的配置文件来覆盖它们，通常这样做是为了为不同的环境提供更具体的配置， local/development、分期、制作等

从 CakePHP 4 开始，默认应用程序模板生成 loads an additional configuration file named app_local.php，它会覆盖一些设置，包括数据源配置。

长话短说，在 config/app_local.php 而不是 config/app.php 中设置凭据。

Answer 2

您需要检查是否有 config/app_local.php 它会覆盖 config/app.php 中的设置。
