每日cron运行终止,因为它超过了最大运行时间

Question

我不知道为什么我的cron运行20分钟而且终止了.在openshift中,如果你运行cron,它会在5分钟后被杀死.如果你用nohup运行,它会在20分钟后被杀死.
这是我在cron_daily上的错误日志.文件update_dave_list运行20分钟:

Thu Nov 19 03:08:08 EST 2015: START daily cron run

问题是update_dave_list运行只需约20秒: update_dave_list内容:

#!/bin/bash
date
nohup /var/lib/openshift/55000094/python/virtenv/bin/python /var/lib/openshift/55000094/app-root/runtime/repo/wsgi/digrin/manage.py crontab run 18e10bf4fb745d8a480230a3 # update dave lists
date

输出:

Št nov 19 03:43:47 EST 2015
nohup: ignoring input and appending output to `nohup.out'
Št nov 19 03:44:05 EST 2015

问题还在于,如果一个人被杀,我的其他日常生活都不会被运行.哦,这是代码,以防你想知道我跑了20秒:

def update_dave_list():
    # if settings.ON_OPENSHIFT:
    response = urlopen("http://www.dripinvesting.org/tools/U.S.DividendChampions.xls")
    excell = xlrd.open_workbook(file_contents=response.read())
    for sheet in range(0,3): #for champions, challengers and contenders
        worksheet = excell.sheet_by_index(sheet)
        list, created = List.objects.get_or_create(name=worksheet.name, short_name=worksheet.name,
                                                   source="http://www.dripinvesting.org/tools/tools.asp")
        num_rows = worksheet.nrows - 1
        curr_row = 5
        symbol_list = []
        while curr_row < num_rows:
            curr_row += 1
            symbol = worksheet.cell(curr_row, 1)
            if symbol.ctype != 1: #break if you are out of symbol
                break
                #print  cell.value.replace(".", "-")
            symbol_list.append(unify_symbol(symbol.value))
            industry = worksheet.cell(curr_row, 2)
            sector = worksheet.cell(curr_row, 77)
            years = worksheet.cell(curr_row, 3)
            try:
                list_stock, created = ListStock.objects.get_or_create(stock=Stock.objects.get(symbol=unify_symbol(symbol.value)))
            except ObjectDoesNotExist:
                AddStock.objects.get_or_create(symbol=unify_symbol(symbol.value))
                continue
            list_stock.industry = industry.value
            list_stock.years_paying = years.value
            if sector.ctype == 1:
                if list_stock.stock.sector == None:
                    sector_obj, created = Sector.objects.get_or_create(name=sector.value)
                    list_stock.stock.sector = sector_obj
                    list_stock.stock.save()
            list_stock.save()
            #add stocks to list
            list.stocks.add(list_stock)
        #delete removed stocks
        for list_stock in list.stocks.all():
            if list_stock.stock.symbol not in symbol_list:
                list.stocks.remove(list_stock)
    return

但它可能不依赖于代码,因为如果我运行我的cron文件(./update_dave_list)它会在20秒内完成,当由cron运行时它将无法完成.知道这里有什么问题吗？

EDIT1: 所以我试着注释掉这样的文件update_dave_list:

#!/bin/bash
#/var/lib/openshift/55a0310e4382ec4b84000094/python/virtenv/bin/python /var/lib/openshift/55a0310e4382ec4b84000094/app-root/runtime/repo/wsgi/digrin/manage.py crontab run 18e10bf4fb92741b69745d8a480230a3 # update dave lists

openshift上的每日cron文件夹如下所示:

drwx------. 2 55a00094 55a00094 4096 nov 22 17:55 .
drwx------. 7 55a00094 55a00094 4096 nov 22 17:39 ..

-rwxr-xr-x. 1 55a00094 55a00094  252 nov 22 17:37 watcher

在我注释掉dave list update之后,这是来自cron_daily.log的日志:

__________________________________________________________________________
Mon Nov 23 03:25:54 EST 2015: START daily cron run
__________________________________________________________________________
/usr/libexec/openshift/cartridges/cron/bin/cron_runjobs.sh: line 114: 28445 Killed                  $executor "$SCRIPTS_DIR"
Warning: daily cron run terminated as it exceeded max run time
__________________________________________________________________________
Mon Nov 23 03:45:54 EST 2015: END daily cron run - status=137
__________________________________________________________________________

我认为这意味着我的文件都没有运行,错误在cron_runjobs.sh中.但我没有得到openshift的支持,报告错误没有帮助(几周前我报告过,还没有更新).奇怪的是,我的每日crons不起作用,每小时cron工作正常.

EDIT2:我试图重启cron cartridge:

rhc cartridge remove cron -a <app>
rhc cartridge add cron -a <app>

没有帮助:

__________________________________________________________________________
Tue Nov 24 03:12:47 EST 2015: START daily cron run
__________________________________________________________________________
/usr/libexec/openshift/cartridges/cron/bin/cron_runjobs.sh: line 114: 211644 Killed                  $executor "$SCRIPTS_DIR"
Warning: daily cron run terminated as it exceeded max run time
__________________________________________________________________________
Tue Nov 24 03:32:47 EST 2015: END daily cron run - status=137
__________________________________________________________________________

我不知道现在该怎么办.如果启动每日cron中的文件,它看起来像这样:

__________________________________________________________________________
Mon Nov 23 13:01:05 EST 2015: START hourly cron run
__________________________________________________________________________
/var/lib/openshift/55a000094/app-root/runtime/repo//.openshift/cron/hourly/add_stocks:
...

但是每日cron不会在日常目录中运行任何文件.

Answer 1

好吧,我想我发现了问题所在.
首先,我可以像这样强制每天运行cron:

/usr/libexec/openshift/cartridges/cron/bin/cron_runjobs.sh daily

这是我每日cron的日志:

__________________________________________________________________________
Wed Nov 25 03:24:19 EST 2015: START daily cron run
__________________________________________________________________________
/var/lib/openshift/55a000094/app-root/runtime/repo//.openshift/cron/daily/update_dave_list:
WARNING:py.warnings:/var/lib/openshift/55a000094/python/virtenv/lib/python2.7/site-packages/django_crontab-0.6.0-py2.7.egg/django_crontab/crontab.py:13: RemovedInDjango19Warning: django.uti$
  from django.utils.importlib import import_module

/usr/libexec/openshift/cartridges/cron/bin/cron_runjobs.sh: line 114: 375681 Killed                  $executor "$SCRIPTS_DIR"
Warning: daily cron run terminated as it exceeded max run time

我认为问题在于update_dave_list.但是当我在update_dave_list文件中打印日期时,如下所示:

#!/bin/bash
/var/lib/openshift/55a000094/python/virtenv/bin/python /var/lib/openshift/55a000094/app-root/runtime/repo/wsgi/digrin/manage.py crontab run 18e10bf4fb92741b69745d8a480230a3 # update dave lists
date

我意识到日期打印在日志中 - > update_dave_list已成功完成!(Wed Nov 25 03:24:38 EST 2015)所以问题必须是在openshift中,不会结束update_dave_list进程或正确拾取另一个文件,但它会在成功完成后写入日志(从未发生过).第二个想法更合乎逻辑.我有一个文件,这是在我的localhost上20分钟内完成的,但是在openshift上它没有准时完成.我通过将这个长时间运行的cron拆分为多个部分(每小时cron)来修复此问题,现在看起来它运行正常.
感谢帮助!我知道这里没有多少人使用Openshift,没有很多日志和信息,调试也不是一件容易的事!再次感谢您的时间和帮助!
