When we say "Personal HTCondor" we mean two things which are actually independent, but which normally go together

1: A single node HTCondor pool
1: A HTCondor pool in which all of the daemons and jobs run as a single user

These instructions show you how to set up HTCondor to be both of these things, but keep in mind that they are actually independent, and you can easily change the configuration to have a multi-node pool running as a single user, or a single-node pool where the daemons run as root (and jobs run unprivileged).

{section: Get HTCondor binaries}

Downloading the tarball/zip release

*: {link: https://research.cs.wisc.edu/htcondor/downloads/ Download Official HTCondor Releases}
*: {link: http://submit-3.batlab.org/results/continuous.php Download Daily HTCondor builds} (click on the row you want, and then on the link under the platform you want)

Or build HTCondor and tar/zip the release_dir directory from the build

*: {wiki: BuildingHtcondorOnUnix Build HTCondor}
and then tar it up.
{code}
# assuming that you build HTCondor V8_4_0-branch in /scratch/build/condor
cd /scratch/build/condor/release_dir
tar czf ../condor-8.4.0-x86_64_RedHat6-unstripped.tar.gz .
{endcode}

For Personal HTCondor we use the tarball/zip release because this lets you control where the binaries will be installed, and will allow you have more than a single version of HTCondor running at once.

{section: Setting up your Personal HTCondor}

The remainder of this guide will assume that you downloaded or built the
condor-8.4.0-x86_64_RedHat6-unstripped.tar.gz tarball.  If you are working with a different tarball, adjust the commands accordingly.

{subsection: Unpack the HTCondor binaries (setting up "RELEASE_DIR")}

We refer to the place where the HTCondor binaries live as RELEASE_DIR, you can unpack the tarball to create this directory using the following commands.
{code}
> cd /scratch
> tar xf <path-to-tarball>/condor-8.2.10-x86_64_RedHat6-unstripped.tar.gz
# optionally rename the directory to something simpler
> mv condor-8.4.0-x86_64_RedHat6-unstripped condor84
{endcode}

The directory */scratch/condor84* will now contain the HTCondor binaries, it will contain subdirectores bin, sbin, libexec, etc and several others.  We call this directory *RELEASE_DIR*.

{subsection: Create configuration (setting up "LOCAL_DIR")}

HTCondor needs configuration files, and at least 3 runtime directories: log, spool and execute.  The condor_install script will create all of these as children of a directory we call *LOCAL_DIR*.  LOCAL_DIR can be the same directory as RELEASE_DIR, or it can be different. In this example we will make it different.

{code}
> mkdir /scratch/local/condor84
> /scratch/condor84/condor_install --local_dir=/scratch/local/condor84
# optional, copy the script that sets up the environment to local_dir
> cp /scratch/condor84/condor.sh /scratch/local/condor84
{endcode}

The directory */scratch/local/condor84* will now contain directories log, spool, and execute.  It will also have a condor_config.local file ready for you to begin customizing the configuration.

The condor.sh script will contain commands to setup the environment so that you can use the HTCondor you have just created. It puts the HTCondor binaries into your path, and sets the CONDOR_CONFIG variable. If you use the sh or bash shell, you can use it like this
{code}
source /scratch/condor84/condor.sh
{endcode}

{subsection: Run your Personal HTCondor}

First, make sure that you will run the correct HTCondor. The =which= command can be used to find out if you will run the correct condor_master:
{code}
> source /scratch/condor84/condor.sh
> which condor_master
/scratch/condor84/sbin/condor_master
{endcode}
Then run condor_master:
{code}
condor_master
{endcode}
Wait a second, and make sure that everything is running:
{code}
ps -x | grep condor
{endcode}
When you are done with your personal HTCondor, you can kill it with:
{code}
condor_off -master
{endcode}

Remember you must use /scratch/condor84/condor.sh or some other method to set the PATH, CONDOR_CONFIG and other environment variables _before you start HTCondor or use an of the tools_.
