yii2 log輸出到file及database，yii2database

編輯config/web.php

首先log要開啟

    'bootstrap' => [
        'log'
    ],

[file]

    'components' => [
        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'exportInterval' => 1,
                ],
            ],
        ],

默認輸出到runtime/logs/app.log

注意webserver或控制台用戶要有寫入該文件的權限

[database]

        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\DbTarget',
                    'levels' => ['error', 'warning', 'trace'],
                ]
            ]
        ],

默認輸出db組件對應的數據庫下{{%log}}表

yii2根目錄下運行下面命令生成對應的table schema

./yii migrate --migrationPath=@yii/log/migrations/

注意config/console.php下也要有和web.php同樣的配置，否則命令執行不成功。

還可以根據不同的環境配置不同的日志模式

    'components' => [
        'log' => [
            'traceLevel' => YII_ENV == 'dev' ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\DbTarget',
                    'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error'],
                ],
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => YII_DEBUG ? ['error', 'warning', 'trace'] : ['error', 'warning'],
                ],
            ],
        ],
    ],
