首先感谢segmentfault.com的“imperat0r_”用户的文章和新浪的“小菜一碟”用户的文章。这是他们的配置文件。我参考也写了一个,在最后呢。
重点说明写在前面。本人用supervisord配置好pyspider后,pyspider一直有问题,不能正常运行。找了很久原因。最后想起,supervisord启动的进程是否正常这个问题。于是果断用supervisorctl命令查看所有管理的进程。果然发现有两个进程启动失败。怎么办?马上修改错误的参数啊!
参数!参数!参数!一定要把参数配置正确,这是王道。
“imperat0r_”的配置
如果你使用源代码启动,可以使用这个配置。如果你使用已编译过的pyspider,请参考下面的配置。只有一个区别,就是启动的路径不一样。我自己的配置文件里,我对参数进行了简要的说明。

新浪的“小菜一碟”的配置:
如果你使用已编译过的pyspider,请参考这个配置。只有一个区别,就是启动的路径不一样。

本人自己的配置文件。
这个配置文件可以使pyspider每个组件单独启动进程,单独管理,不影响整体运行。我对这个配置文件学了很久,下面记录一下详细信息,希望对新手有用。每个参数的中文说明见下一节。
