RE: [Condor-users] Condor Install newbie Questions

hi terrence...

given that i'm realtively new to condor.. and the install process.. i
figured i'd try to answer some of your questions....

each machine in your pool will have to have condor installed on the box.
this includes the condor_master app. from the docs that i've seen, it
appears that if your client box is going to be used to simply submit/run
jobs, then you'll probably have _master, _sched, and _start.

the docs that i've seen (and in my own setup) state that you should install
condor as root, but that you should have a 'condor' account setup on the

the condor apps on linux run as condor, so i would assume that they will
also run as condor under a windows env.

the condor_master should be added to the services on each of your boxes so
it starts on bootup of the system. this will in turn start the other
required processes.

an issue that you're going to have to resolve, and the most critical part
from my perspective, is correctly getting the condor_config files setup.

good luck, have fun!!!

Subject: [Condor-users] Condor Install newbie Questions


I am a little confused how to install and start Condor.

Our Envrionment:

We do have a PC-Pool of 30 machines plus 1 fileserver. The /home/...
is mapped onto all the Pool machines by the fileserver. Additiional all
are managed by the fileserver. For example the user 'condor' or 'terence'
the same for all machines and therefore exist only once. The only exception
is the user root. He exists seperately on all machines, so that there are 31
different root users. The consequence of this configuration is, that for
example root on machine 20 has no write access to /home/condor/, since this
directory is located on the fileserver, and root on machine 20 has no rights
on the fileserver.

The Questions:

I want to install condor into /home/condor/condor/. Central Manager is
supposed to be the fileserver, all other machines are for executing or
submitting jobs.

Shall I install Condor as user root or as user condor?

Shall I start condor_master as user root or as user condor?

Has condor_master to be started on all machines or on the Central Manager
(fileserver) only?

Thanks for help,
