Open Source System Administration Framework - Func
- 1. オープンソースなシステム管理フレームワークFunc第4回KLab勉強会(株)paperboy&co.宮下 剛輔http://mizzy.org/2008/03/28
- 4. Funcとは？
- 5. Funcとは？FedoraUnified Network Controllerシステム管理フレームワークと勝手に呼んでますシステム管理用のプログラムを開発するためのフレームワークgihyo.jpで連載中ですYou Can Do Almost Anything With Itフレームワークなので「具体的な何かができる」というものではない逆にいえば何でもできます
- 7. サンプルその1# func target.example.org call hardwareinfo# func "*.example.org"call yumupdate# func "*" call moduleyouwrotemethodname1234 5678 firetruck acmelabs hike!
- 8. サンプルその2import func.overlord.client as fc results = fc.Client("*").service.status("httpd")for (host, rc) inresults.iteritems():if rc != 0: fc.Client(host).service.start("httpd")
