用supervisor控制celery時的腳本

注意啓停的前後順序及判斷便可。

這樣，在更改task以後，要重啓就方便不少啦。。

#!/bin/sh

supervisord_count=`ps -elf | grep celery | grep -v grep | wc -l`
if [ $supervisord_count -gt 0 ]; then
    ps aux|grep -v grep|grep supervisord|awk '{print $2}'|xargs kill -9
fi

celery_count=`ps -elf | grep celery | grep -v grep | wc -l`
if [ $celery_count -gt 0 ]; then
    ps aux|grep -v grep|grep celery|awk '{print $2}'|xargs kill -9
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!'

另給一個最基本的supervisor的設置：

; 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".

logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)

logfile_backups=10           ; (num of main logfile rotation backups;default 10)

;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
