Configuring authManager using DbManager in yii2-app-base - php

Question

I'm going through Security-Authorization Tutorial to configure authManager using DbManager.
After declaring the below code in web.php
<?php
$params = require(__DIR__ . '/params.php');
$config = [
'id' => 'basic',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'components' => [
'urlManager' => [
'showScriptName' => false,
'enablePrettyUrl' => true
],
'authManager' => [
'class' => 'yii\rbac\DbManager',
],
'request' => [
// !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
'cookieValidationKey' => 'tYXyeisqgn9Qn_baaI6JRV4a6NY54nrq',
],
'cache' => [
'class' => 'yii\caching\FileCache',
],
'user' => [
'identityClass' => 'app\models\User',
'enableAutoLogin' => true,
],
'errorHandler' => [
'errorAction' => 'site/error',
],
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
// send all mails to a file by default. You have to set
// 'useFileTransport' to false and configure a transport
// for the mailer to send real emails.
'viewPath' => '#backend/mail',
'useFileTransport' => true,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'localhost',
'username' => 'root',
'password' => '',
'port' => '8080',
'encryption' => 'tls',
],
],
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'db' => require(__DIR__ . '/db.php'),
],
'params' => $params,
];
if (YII_ENV_DEV) {
// configuration adjustments for 'dev' environment
$config['bootstrap'][] = 'debug';
$config['modules']['debug'] = [
'class' => 'yii\debug\Module',
];
$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
'class' => 'yii\gii\Module',
];
}
return $config;
And, this code in console.php
<?php
Yii::setAlias('#tests', dirname(__DIR__) . '/tests');
$params = require(__DIR__ . '/params.php');
$db = require(__DIR__ . '/db.php');
return [
'id' => 'basic-console',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log', 'gii'],
'controllerNamespace' => 'app\commands',
'modules' => [
'gii' => 'yii\gii\Module',
],
'components' => [
'authManager' => [
'class' => 'yii\rbac\DbManager',
],
'cache' => [
'class' => 'yii\caching\FileCache',
],
'log' => [
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'db' => $db,
],
'params' => $params,
];
config/db.php
<?php
return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=danishYii',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
];
I typed ./yii migrate --migrationPath=vendor/yiisoft/yii2/rbac/migrations
in my terminal. This command i got from Component is not getting loaded -Stack overflow
I got this error in my terminal
Exception 'yii\db\Exception' with message 'SQLSTATE[HY000] [2002]
Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)'
I'm very new to Yii. So please don't mind if this is a silly question.
Please help me to rectify this problem.

Check if in your
console/config/main.php
you have a proper configuration for db access like this sample for yii2-app-advanced template
'components' => [
'db' => [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=your_hostname;dbname=your_dbname',
'username' => 'your_username',
'password' => 'your_password',
'charset' => 'utf8',
'enableSchemaCache' => true,
],
for basic template
be sure you have in basic/console/config.php a reference to db in component secion like this
return [
.......
'components' => [
......
'db' => require(__DIR__ . '/db.php'),
],
......
];
and then in basci/config/db.php a properly db config
return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=your_hostname;dbname=your_dbname',
'username' => 'your_username',
'password' => 'your_password',
'charset' => 'utf8',
];
