在你的操作系統(tǒng)，如果是linux的話，添加以下計(jì)劃任務(wù)。 

* * * * *  /usr/bin/php /webrootpath/e/tasks/backend_cronjob.php。

把代碼傳到 /e/tasks/ 下。 

這個(gè)腳本將替代后臺(tái)的定時(shí)刷新，你不用在開著后臺(tái)了，它幫你定時(shí)刷新。

適用場景：全戰(zhàn)靜態(tài)化，需要定時(shí)刷新。（比如首頁有點(diǎn)計(jì)量，排行榜這樣的數(shù)據(jù)） 同時(shí)適用于，需要在多臺(tái)服務(wù)器上生成內(nèi)容的情況。
