前言：
而今我们对“ubuntu804中文”大致比较着重，姐妹们都需要学习一些“ubuntu804中文”的相关文章。那么小编也在网摘上汇集了一些有关“ubuntu804中文””的相关知识，希望兄弟们能喜欢，姐妹们一起来了解一下吧！supervisord介绍
supervisor就是用Python开发的一套通用的进程管理程序，能将一个普通的命令行进程变为后台daemon，并监控进程状态，异常退出时能自动重启。
关键进程：
supervisord ：运行supervisor时会启动一个进程，叫supervisord，它负责启动所管理的进程，并将所管理的进程作为自己的子进程来启动，而且可以在所管理的进程出现崩溃时自动重启。
supervisorctl：是命令行管理工具，可以用来执行 stop、start、restart 等命令，来对这些子进程进行管理。
supervisor：是所有进程的父进程，管理着启动的子进展，supervisor以子进程的PID来管理子进程，当子进程异常退出时supervisor可以收到相应的信号量。
