supervisor：是用Python開(kāi)發(fā)的一個(gè)client/server服務(wù)椿访，是Linux/Unix系統(tǒng)下的一個(gè)進(jìn)程管理工具躬柬，不支持Windows系統(tǒng)挨决。它可以很方便的監(jiān)聽(tīng)敦锌、啟動(dòng)、停止忙芒、重啟一個(gè)或多個(gè)進(jìn)程示弓。用Supervisor管理的進(jìn)程讳侨，當(dāng)一個(gè)進(jìn)程意外被殺死呵萨，supervisort監(jiān)聽(tīng)到進(jìn)程死后，會(huì)自動(dòng)將它重新拉起.但是只支持前臺(tái)程序.
