supervisord python腳本：退出狀態1;沒有預期的循環

我想運行下面的代碼使用supervisord，但它開始重新啓動第二我執行supervisord -c /etc/supervisord.conf
請指教？supervisord python腳本：退出狀態1;沒有預期的循環

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()

這裏是supervisord.log

輸出日誌從supervisord.conf

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

有非零狀態可能意味着Python解釋器退出，因爲它捕獲的異常退出;通常它會在它的stderr上打印回溯，這可能在某個日誌中;也許'/ var/log/messages'？如果你無法在任何地方找到它，你應該自己發現異常並將它記錄在你能找到它的地方。 – SingleNegationElimination

我在終端連續運行了python腳本15分鐘，結果沒有錯誤。我將stdout_logfile =/etc/front.log行添加到了supervisord.conf文件中，它只是在日誌中輸出了'last'的值4次。 – phill

錯誤消息不會去標準輸出;在當前的'stdout_logfile'中使用'stderr_logfile'或'redirect_stderr'。在'/ etc'中放入日誌也不是一個好主意。那麼'/ var/log'呢？ – SingleNegationElimination

由於eggonlegs在評論中提到，你可以通過檢查進一步探索您的日誌/var/log/supervisor/目錄。我有完全相同的問題，我發現了以下文件被創建：

celery_worker-stderr---supervisor-DEjyLf.log

（作爲我的程序[program:front]的名稱）。

通過檢查它我發現：

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'

所以我的問題是由於權限，因爲我沒有在我的celery_worker.conf文件中指定directory。一旦指定：

directory = /path/to/logs/

一切工作完美。

它可能不是相同的錯誤，但絕對檢查這些stderr或stdout日誌將幫助
