.. _admin_install_linux:
Linux (as root)
===============
For ease of installation on Linux, we provide a script that will automatically
download, install and start HTCondor.
Quickstart Installation Instructions
------------------------------------
.. warning::
* RedHat systems must be attached to a subscription.
* Debian and Ubuntu containers don't come with ``curl`` installed,
so run the following first.
.. code-block:: shell
apt-get update && apt-get install -y curl
The command below shows how to download the script and run it immediately;
if you would like to inspect it first, see
:ref:`Inspecting the Script <inspecting_the_script>`. The default behavior
will create a complete HTCondor pool with its multiple roles on one computer,
referred to in this manual as a "minicondor."
Experienced users who are making an HTCondor pool out of multiple machines
should add a flag to select the desired role; see
the :doc:`admin-quick-start` for more details.
.. code-block:: shell
curl -fsSL https://get.htcondor.org | sudo /bin/bash -s -- --no-dry-run
If you see an error like ``bash: sudo: command not found``, try re-running
the command above without the ``sudo``.
.. _inspecting_the_script:
.. admonition:: Inspecting the Script
:class: tip
If you would like to inspect the script before you running it on
your system as root, you can:
* `read the script <https://get.htcondor.org>`_;
* compare the script to the versions `in our GitHub repository <https://github.com/htcondor/htcondor/blob/master/src/condor_scripts/get_htcondor>`_;
* or run the script as user ``nobody``, dropping the ``--no-dry-run``
flag. This will cause the script to print out what it would do if
run for real. You can then inspect the output and copy-and-paste it
to perform the installation.
.. include:: minicondor-test-and-quickstart.include
Setting Up a Whole Pool
-----------------------
The details of using this installation procedure to create a multi-machine
HTCondor pool are described in the admin quick-start guide:
:doc:`admin-quick-start`.
