Supervisor 是一个客户端服务器系统，允许用户监控和控制类 Unix 操作系统上的进程数。

官网 http://supervisord.org

安装
1. easy_install supervisor
2.

配置文件说明

HTTP/XML-RPC 相关配置
[unix_http_server]
file = /tmp/supervisor.sock
chmod = 0777
chown= nobody:nogroup
username = user
password = 123

Web管理界面配置
[inet_http_server]
port = 127.0.0.1:9001
username = user
password = 123

[supervisorctl]
serverurl = unix:///tmp/supervisor.sock 和[unix_http_server]匹配
username = chris
password = 123
prompt = mysupervisor

日志 环境等配置
[supervisord]
logfile = /tmp/supervisord.log
logfile_maxbytes = 50MB
logfile_backups=10
loglevel = info
pidfile = /tmp/supervisord.pid
nodaemon = false
minfds = 1024
minprocs = 200
umask = 022
user = chrism
identifier = supervisor
directory = /tmp
nocleanup = true
childlogdir = /tmp
strip_ansi = false
environment = KEY1="value1",KEY2="value2"

配置单个进程
[program:theprogramname]

priority=999 ; the relative start priority (default 999)
autostart=true ; start at supervisord start (default: true)
autorestart=unexpected ; whether/when to restart (default: unexpected)
startsecs=1 ; number of secs prog must stay running (def. 1)
startretries=3 ; max # of serial start failures (default 3)
exitcodes=0,2 ; 'expected' exit codes for process (default 0,2)
stopsignal=QUIT ; signal used to kill process (default TERM)
stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10)
stopasgroup=false ; send stop signal to the UNIX process group (default false)
killasgroup=false ; SIGKILL the UNIX process group (def false)
user=chrism ; setuid to this UNIX account to run the program
redirect_stderr=true ; redirect proc stderr to stdout (default false)
stdout_logfile=/a/path ; stdout log path, NONE for none; default AUTO
stdout_logfile_maxbytes=1MB ; max # logfile bytes b4 rotation (default 50MB)
stdout_logfile_backups=10 ; # of stdout logfile backups (default 10)
stdout_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0)
stdout_events_enabled=false ; emit events on stdout writes (default false)
stderr_logfile=/a/path ; stderr log path, NONE for none; default AUTO
stderr_logfile_maxbytes=1MB ; max # logfile bytes b4 rotation (default 50MB)
