1. supervisord The server piece of supervisor is named supervisord. It is responsible for starting child programs at its own invocation, responding to commands from clients, restarting crashed or exited subprocesseses, logging its subprocess stdout and stderr output, and generating and handling “events” corresponding to points in subprocess lifetimes.
The server process uses a configuration file. This is typically located in /etc/supervisord.conf. This configuration file is an “Windows-INI” style config file. It is important to keep this file secure via proper filesystem permissions because it may contain unencrypted usernames and passwords.
2. supervisorctl The command-line client piece of the supervisor is named supervisorctl. It provides a shell-like interface to the features provided by supervisord. From supervisorctl, a user can connect to different supervisord processes, get status on the subprocesses controlled by, stop and start subprocesses of, and get lists of running processes of a supervisord.
The command-line client talks to the server across a UNIX domain socket or an internet (TCP) socket. The server can assert that the user of a client should present authentication credentials before it allows him to perform commands. The client process typically uses the same configuration file as the server but any configuration file with a [supervisorctl] section in it will work.
3. Web Server A (sparse) web user interface with functionality comparable to supervisorctl may be accessed via a browser if you start supervisord against an internet socket. Visit the server URL (e.g. http://localhost:9001/) to view and control process status through the web interface after activating the configuration file’s [inet_http_server] section.
4. XML-RPC Interface The same HTTP server which serves the web UI serves up an XML-RPC interface that can be used to interrogate and control supervisor and the programs it runs. See XML-RPC API Documentation. Platform Requirements

supervisor自带有Web Server, 可以通过页面来管理进程, 前提是开启配置文件中的[inet_http_server]项。 如果服务器是单网卡，可以修改如下： [inet_http_server] ; inet (TCP) server disabled by default port=127.0.0.1:51000 ; (ip_address:port specifier, *:port for all iface) ;username=user ; (default is no username (open server)) ;password=123 ; (default is no password (open server))
如果是多网卡，则需要指定一张网卡: [inet_http_server] ; inet (TCP) server disabled by default port=192.168.2.13:51000 ; (ip_address:port specifier, *:port for all iface) ;username=user ; (default is no username (open server)) ;password=123 ; (default is no password (open server))
