Edit config/web.php

First the log must be enabled

    &#39;bootstrap&#39; => [
        &#39;log&#39;
    ],

Copy after login

[file]

    &#39;components&#39; => [
        &#39;log&#39; => [
            &#39;targets&#39; => [
                [
                    &#39;class&#39; => &#39;yii\log\FileTarget&#39;,
                    &#39;exportInterval&#39; => 1,
                ],
            ],
        ],

Copy after login

The default output is to runtime/logs/app.log

Note that the webserver or console user must have permission to write to the file

[database]

        &#39;log&#39; => [
            &#39;targets&#39; => [
                [
                    &#39;class&#39; => &#39;yii\log\DbTarget&#39;,
                    &#39;levels&#39; => [&#39;error&#39;, &#39;warning&#39;, &#39;trace&#39;],
                ]
            ]
        ],

Copy after login

The default output is the {{%log}} table under the database corresponding to the db component

Run the following command in the yii2 root directory to generate the corresponding table schema

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

Copy after login

Note that config/console.php must also have the same configuration as web.php, otherwise the command execution will not be successful.

You can also configure different log modes according to different environments

    &#39;components&#39; => [
        &#39;log&#39; => [
            &#39;traceLevel&#39; => YII_ENV == &#39;dev&#39; ? 3 : 0,
            &#39;targets&#39; => [
                [
                    &#39;class&#39; => &#39;yii\log\DbTarget&#39;,
                    &#39;levels&#39; => YII_DEBUG ? [&#39;error&#39;, &#39;warning&#39;, &#39;trace&#39;] : [&#39;error&#39;],
                ],
                [
                    &#39;class&#39; => &#39;yii\log\FileTarget&#39;,
                    &#39;levels&#39; => YII_DEBUG ? [&#39;error&#39;, &#39;warning&#39;, &#39;trace&#39;] : [&#39;error&#39;, &#39;warning&#39;],
                ],
            ],
        ],
    ],
