Question

我试图使用supervisord运行以下python代码，但它开始重新启动第二个i执行supervisord -c /etc/supervisord.conf
请指教？

import urllib2
import time

def goget():
    url = "http://hitch.tv/grabs.php"
    data = urllib2.urlopen(url)
    grabbedpic = data.read()

    with open('/root/python/tmp.txt', 'r') as tmpfile:
        last=tmpfile.read().replace('\n','')

    msgstr = []
    u = 'http://hitch.tv/'

    print last
    if grabbedpic == last:
        print "same pic"
    else:
        msgstr = u + grabbedpic
        //send email with msgstr here 

        with open('tmp.txt', 'w') as tmpfile:
            tmpfile.write(grabbedpic)

    time.sleep(15)

while True:
    goget()

这是来自supervisord.log的日志输出

来自supervisord.conf的

[program:front]
command=python /root/python/front.py
process_name = front
autostart = true
autorestart = true
startsecs = 10
stopwaitsecs = 30

作为评论中提到的eggonlegs，您可以通过查看/var/log/supervisor/目录来浏览更多日志。我有同样的问题，我发现创建了以下文件：

celery_worker-stderr---supervisor-DEjyLf.log

（作为我的计划的名称[program:front]）。

通过检查，我发现：

  File "/usr/lib/python3.4/logging/__init__.py", line 1006, in __init__
    StreamHandler.__init__(self, self._open())
  File "/usr/lib/python3.4/logging/__init__.py", line 1030, in _open
    return open(self.baseFilename, self.mode, encoding=self.encoding)
PermissionError: [Errno 13] Permission denied: '/devel.log'

所以我的问题是由于权限，因为我没有在directory文件中指定celery_worker.conf。一旦指定：

directory = /path/to/logs/

一切都很完美。

可能不是同一个错误，但绝对检查这些stderr或stdout日志会有所帮助
