Editing Creating Python Cron Job On Synology

[[Category:NAS]][[Category:Synology]][[Category:Python]]
== Objective ==

To install a python script on Synology NAS and run it as a cron job.

== Prerequisites ==

=== python ===

Install Python3 using the Package Center app in the DSM.

=== pip ===

SSH to the DiskStation and install `pip` with

<syntaxhighlight lang="bash">
$ sudo curl -k https://bootstrap.pypa.io/get-pip.py | python 3
</syntaxhighlight>

This will install `pip` at `/volume1/@appstore/py3k/usr/local/bin/`, but the `pip` command isn't automatically available.

<syntaxhighlight lang="bash">
$ sudo ln -s /volume1/@appstore/py3k/usr/local/bin/pip /usr/local/bin/pip
</syntaxhighlight>

=== virtualenv ===

Once `pip` is installed, use it to install `virtualenv`, and make sure the command is available from the command line:

<syntaxhighlight lang="bash">
$ sudo pip install virtualenv
$ sudo ln -s /volume1/@appstore/py3k/usr/local/bin/virtualenv /usr/local/bin/virtualenv
</syntaxhighlight>

Create a virtual environment for the python script:

<syntaxhighlight lang="bash">
$ virtualenv -p /volume1/@appstore/py3k/usr/local/bin/python3 venv
</syntaxhighlight>
