Yii2 将日志记录到数据库中

Yii2默认日志记录到文件中，通过配置log组件来重新将日志保存到数据库中

打开config目录下console.php文件，修改log配置

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

　　打开cmd 命令行，进入Yii根目录，开始创建数据库

 yii migrate [email protected]/log/migrations/

　　输入yes

数据库中就会创建好log表，配置web.php文件的log的targets将日志记录到数据库中

        ‘log‘ => [
            ‘traceLevel‘ => 0,
            ‘targets‘ => [
                [
                    ‘class‘ => ‘yii\log\DbTarget‘,
                    ‘levels‘ => [‘error‘, ‘warning‘, ‘trace‘, ‘info‘],
                ],
            ],
        ],

　　重新访问网站，查看log表:
