运行生成配置文件：

[[email protected] /]# echo_supervisord_conf > /etc/supervisord.conf
...
pkg_resources.DistributionNotFound: meld3>=0.6.5
找到supervisor-3.3.1-py2.7.egg-info/requires.txt，把文件里面meld3 >= 0.6.5注释掉，然后再执行

配置

[program:dopcelerybeat]
command=python manage.py celery beat
numprocs=1
directory=/data1/vhosts/dop.leju.com/
autostart=true
startsecs=10
startretries=3
stopwaitsecs=600
killasgroup=true
user=root
redirect_stderr=true
stdout_logfile=/data1/logs/supervisord-celery-beat.log
stderr_logfile=/data1/logs/supervisord-celery-beat-error.log

[program:dopceleryworker]
command=python manage.py celery worker -l info
numprocs=1
directory=/data1/vhosts/dop.leju.com/
autostart=true
startsecs=10
startretries=3
stopwaitsecs=600
killasgroup=true
user=root
redirect_stderr=true
stdout_logfile=/data1/logs/supervisord-celery-worker.log
stderr_logfile=/data1/logs/supervisord-celery-worker-error.log

[group:dopcelery]
programs=dopcelerybeat,dopceleryworker
; priority=999                  ; the relative start priority (default 999)

运行celery时报错的解决方法：

1st solution - Manually type command at terminal
$ export C_FORCE_ROOT=‘true‘

2nd solution - Edit shell configuration
$ vi ~/.bashrc

    # add following line
    export C_FORCE_ROOT=‘true‘

$ source ~/.bashrc

3rd solution - Edit manage.py of Django
import os 

if __name__ == ‘__main__‘:
    os.environ.setdefault(‘C_FORCE_ROOT‘, ‘true‘)
    os.environ.setdefault(‘DJANGO_SETTINGS_MODULE‘, ‘{PATH TO SETTINGS FILE}‘)

    execute_from_command_line(sys.argv)

命令supervisorctl可以使用start/stop/status管理每个进程
