Installing Python for ArcGIS Server on Linux

[RichardGordon2]

I am attempting to install the Python 3 runtime on a Linux machine in order to allow me to automate the running of a script without the need to install ArcGIS Server, but I am unable to install  "arcgis-server-py3" package. The debian based machine has Anaconda 2019.07 installed and with conda info command showing

However when I attempt to install arcgis-server-py3 the following is returned

(base) root@70ec06d98032:/# conda install -c esri arcgis-server-py3
Collecting package metadata (current_repodata.json): done

Initial quick solve with frozen env failed. Unfreezing env and trying again.

I am able to install none ESRI Conda packages. Do I need to add in the ESRI channel somehow?

ArcPy won't run unless you have a licensed Esri product (ArcGIS Desktop, ArcGIS Enterprise, ArcGIS Runtime, etc...) installed on the machine.

To follow up on my earlier comment, I think you may be confusing the meaning in Esri's documentation:  Python 3 runtime for ArcGIS Server on Linux—ArcGIS Server Administration (Linux) | ArcGIS Enterprise 

ArcGIS Server provides the option to use a Python 3 runtime for command line ArcPy scripts. Select tools can be executed with a Python 3.x runtime that is installed independently of ArcGIS Server.

The term "installed independently" doesn't mean it runs independently.  If you look at the Conda package information at https://anaconda.org/esri/arcgis-server-py3 

Description

This extension enables use of ArcPy from a native Linux environment. This requires that ArcGIS Server for Linux is installed on the machine.

Richard Gordon‌ I'm running into the exact same issue. Does installing Conda and the arcgis-server-py3 on a machine that already has ArcGIS Server installed fix the problem as Joshua Bixby suggests ?

[RichardGordon2]

Joshua was correct in that I misunderstood the wording in the article. Since ArcGIS Server needed to be installed in order to run Python anyway script we decided to just publish it to ArcGIS Server as a GP tasks and call that as needed rather than try to run it independently.

[DrewDowling]

OK. Thanks for the response.
