用supervisor控制celery时的脚本

注意启停的先后顺序及判断即可。

这样，在更改task之后，要重启就方便很多啦。。

#!/bin/sh

supervisord_count=`ps -elf | grep celery | grep -v grep | wc -l`
 ]; then

fi

celery_count=`ps -elf | grep celery | grep -v grep | wc -l`
 ]; then

fi

/usr/bin/python /usr/local/python27/bin/supervisord -c /P/supervisord_prd.conf
sh /usr/local/nginx/sbin/uwsgi9090 reload
/usr/local/nginx/sbin/nginx -s reload

echo 'finished!'

另给一个最基本的supervisor的设置：

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".

[supervisord]
logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=           ; (num of main logfile rotation backups;default )
loglevel=info                ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=false               ; (start in foreground if true;default false)
minfds=                  ; (min. avail startup )
minprocs=                 ; (min. avail process descriptors;default )
;umask=                   ; (process )
;user=chrism                 ; (default is current user, required if root)
;identifier=supervisor       ; (supervisord identifier, default is 'supervisor')
;directory=/tmp              ; (default is not to cd during start)
;nocleanup=true              ; (don't clean up tempfiles at start;default false)
;childlogdir=/tmp            ; ('AUTO' child log dir, default $TEMP)
;environment=KEY="value"     ; (key value pairs to add to environment)
;strip_ansi=false            ; (strip ansi escape codes in logs; def. false)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket
