Assume the Yii project path is /home/apps/

1. Create file /home/apps/protected/commands/crons.php

<?<span php

</span><span $yii</span> = '/home/apps/framework/yii.php'<span ;

</span><span require_once</span>(<span $yii</span><span );  

</span><span $configFile</span> = <span dirname</span>(<span __FILE__</span>).'/../config/console.php'<span ;

Yii</span>::createConsoleApplication(<span $configFile</span>)->run();

Copy after login

2. Create the required configuration file /home/apps/protected/config/console.php, configure the required components, database connections, logs and other information. The format is similar to the main configuration file main.php

<?<span php  
</span><span return</span> <span array</span><span ( 
    </span>'basePath'=><span dirname</span>(<span __FILE__</span>).DIRECTORY_SEPARATOR.'..', 

    'name'=>'Emergency',

    'import'=><span array</span><span (  
            </span>'application.models.*',
            'application.components.*', 
            'application.extensions.*',<span 
    )</span>, 

    'components'=><span array</span><span (
        </span>'log'=><span array</span><span (
            </span>'class'=>'CLogRouter',
            'routes'=><span array</span><span (
                </span><span array</span><span (
                    </span>'class'=>'CFileLogRoute',
                    'levels'=>'info, warning, error',<span 
                )</span>,<span 
            )</span>,<span 
        )</span>, 
        'db'=><span array</span><span (
            </span>'class'=>'application.extensions.PHPPDO.CPdoDbConnection',
            'pdoClass' => 'PHPPDO',
            'connectionString' => 'mysql:host=xxxx;dbname=xxx',
            'emulatePrepare' => <span true</span>,
            'username' => 'xxx',
            'password' => 'xxx',
            'charset' => 'utf8',
            'tablePrefix' => 'tbl_',<span 
        )</span>,<span 
    )</span>,  
        
    'params' => <span require</span>('params.php'),<span 
);</span>

3. Create a new TestCommand class under /home/apps/protected/commands/ and inherit CConsoleCommand. In TestCommand, you can use the project’s configuration information and Yii’s various methods

<?<span php  
</span><span class</span> TestCommand  <span extends</span><span  CConsoleCommand  
{  
    </span><span public</span> <span function</span><span  run()
    {  
        </span>...<span 
    }  
}</span>

Copy after login

4. Create scheduled tasks

$ crontab -e

Copy after login

Insert

1 * * * * /home/php/bin/php -f /home/apps/<span protected</span>/commands/crons.php Test &

Copy after login

means to execute the contents of the TestCommand class in the first minute of every hour. Similarly, you can create other classes under /home/apps/protected/commands/ and execute them using the command line.
