Cron and virtualenv
You should be able to do this by using the python
in your virtual environment:
/home/my/virtual/bin/python /home/my/project/manage.py command arg
EDIT: If your django project isn't in the PYTHONPATH, then you'll need to switch to the right directory:
cd /home/my/project && /home/my/virtual/bin/python ...
You can also try to log the failure from cron:
cd /home/my/project && /home/my/virtual/bin/python /home/my/project/manage.py > /tmp/cronlog.txt 2>&1
Another thing to try is to make the same change in your manage.py
script at the very top:
#!/home/my/virtual/bin/python
Running source
from a cronfile won't work as cron uses /bin/sh
as its default shell, which doesn't support source
. You need to set the SHELL environment variable to be /bin/bash
:
SHELL=/bin/bash*/10 * * * * root source /path/to/virtualenv/bin/activate && /path/to/build/manage.py some_command > /dev/null
It's tricky to spot why this fails as /var/log/syslog
doesn't log the error details. Best to alias yourself to root so you get emailed with any cron errors. Simply add yourself to /etc/aliases
and run sendmail -bi
.

Don't look any further:
0 3 * * * /usr/bin/env bash -c 'cd /home/user/project && source /home/user/project/env/bin/activate && ./manage.py command arg' > /dev/null 2>&1
Generic approach:
* * * * * /usr/bin/env bash -c 'YOUR_COMMAND_HERE' > /dev/null 2>&1
The beauty about this is you DO NOT need to change the SHELL
variable for crontab from sh
to bash
