我在Dotcloud上运行了一个Django应用程序。我尝试添加Logentries日志记录，这些日志记录在我的网站的正常使用情况下工作，但导致我的cron作业因此错误而失败 -
Traceback (most recent call last):

ValueError: Unable to configure handler 'logentries_handler': expected string or buffer
这是从cron -
运行的脚本之一#!/bin/bash
echo "Loading definitions - check /var/log/supervisor/availsserver.log for results"
. /etc/profile
/home/dotcloud/env/bin/python /home/dotcloud/current/my_project/manage.py load_definitions
这些是我对Logentries的设置 -
'logentries_handler': {
'token': os.getenv("LOGENTRIES_TOKEN"),
'class': 'logentries.LogentriesHandler'
}
....
'logentries': {
'handlers': ['logentries_handler'],
'level': 'INFO',
},
当我dotcloud env list时，LOGENTRIES_TOKEN就在那里。
这是症状的摘要 -
- Logetries日志记录在正常使用情况下从站点进行
- 如果我手动运行脚本 - dotcloud run www ~/current/scripts/load_definitions.sh它可以正常运行
- 如果我从我的settings.py中删除了Logentries设置，则可以使用cron作业
- 如果Logentries条目在我的settings.py
我花了好几个小时试图找到解决方案。有人可以帮忙吗？
答案 0 :(得分：0)
您是否尝试过直接从~/environment.json或~/environment.yml读取值，而不是从导出的shell环境中读取值？
答案 1 :(得分：0)
我已经解决了这个问题
这是之前的crontab -
0 13 * * * /home/dotcloud/current/scripts/load_definitions.sh 2>&1 | mail -s "Load definitions result" myemail@example.com.au
哪个不起作用。
这是现在的样子 -
0 13 * * * /bin/bash -l -c '/home/dotcloud/current/scripts/load_definitions.sh' 2>&1 | mail -s "Load definitions result" myemail@example.com.au
哪个有效。添加/bin/bash -l -c修复它。也许有人可以告诉我它为什么不按原样运作？
