使用CakePHP时无法连接到本地MySQL数据库

Question

我有这个配置：

'default' => [
    'className' => 'Cake\Database\Connection',
    'driver' => 'Cake\Database\Driver\Mysql',
    'persistent' => false,
    'host' => 'localhost',
    /**
     * CakePHP will use the default DB port based on the driver selected
     * MySQL on MAMP uses port 8889, MAMP users will want to uncomment
     * the following line and set the port accordingly
     */
    //'port' => 'nonstandard_port_number',
    'username' => 'root',
    'password' => 'root',
    'database' => 'addressbook',
    'encoding' => 'utf8',
    'timezone' => 'UTC',
    'cacheMetadata' => true,

    /**
     * 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'],
],

我有一个本地MySql数据库，其登录参数与我在上面输入的参数相同，但是在新安装的CakePHP的首页上，接下来告诉我：

CakePHP无法连接到数据库。

无法建立与数据库的连接：SQLSTATE [HY000] [1045]用户'root'@'localhost'的访问被拒绝（使用密码：是）

我该如何解决？ 我通过My​​Sql Workbench用此登录名和密码连接起来很好。 是什么阻止Cake Framework做到这一点？

Answer 1

您是否加载了使您能够在配置中连接到MYSQL的模块？ 基本上，您需要确保php.ini的以下行注释为extension = php_mysql.dll extension = php_mysqli.dll

Answer 2

用户名或密码不正确时，通常会显示此错误消息。

CakePHP is NOT able to connect to the database.

Connection to database could not be established: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

因此请确保root用户的密码为root。

在MySQL中，默认root的密码为空。
