Obtaining the Connect Client distribution

The first step in installation is to grab the latest copy of the client from GitHub:

$ ssh login.mycluster.edu            # [your cluster site here]
$ wget stash.osgconnect.net/+connect/connect-client-0.5.3.tar.gz
$ tar xzf connect-client-0.5.3.tar.gz
$ cd connect-client-0.5.3

This obtains a copy of the distribution and sets your shell's working directory to that copy.

Installation using environment modules

To install the Connect Client you will need Python 2.x and a C compiler. Python 3 is not supported. At some sites, module load python will load Python 3, so it might be necessary to load Python 2 explicitly. For example:

$ module load gcc
$ module load python/2.7.6

You will also need pip, the Python package installation program. Very often it is part of the Python installation itself.

We've seen some indication that if your system uses Python 2.6,
it may be necessary to have installed the **pycrypto** module
already.  With Python 2.7 and up this dependency is handled

Choose a directory to install Connect Client into. You should know what directories are used at your site. For these examples we'll /software as the location of software tools, and /software/modulefiles as the location of module files. Run ./install.sh with these two directories:

$ ./install.sh /software/connect-client-0.5.2 /software/modulefiles

N.B. There may be dependencies in your module environment that should be loaded when connect-client is loaded. In particular, at many sites Python is a module dependency. Putting module load statements into the module file helps users load the software consistently. After a site installation please review the installed modulefile -- search for the text "module load" to find the right spot. All modules that were loaded when you installed the software will be listed but commented out. Uncomment any that are true dependencies.

Using RPM and Yum

We've prepared an RPM for Connect Client which you can install on any Linux system that is based on Red Hat Enterprise Linux 6 (EL6). This includes CentOS 6 and Scientific Linux 6.

To start, install the CI Connect Yum repository with this command:

$ yum install http://repo.ci-connect.net/yum/ci-connect/6/x86_64/ci-connect-release-6-1.noarch.rpm

This will give you access to CI Connect-related software packages, and to software updates as they become available. You can see this in the output of yum repolist:

$ yum repolist
Loaded plugins: downloadonly, security
repo id                    repo name                                                          status
EPEL-6-x86_64              EPEL-6-x86_64                                                      11808
SL-64-x86_64               SL-64-x86_64                                                        6410
SL-64-x86_64-security      SL-64-x86_64-security                                               3465
ci-connect                 CI Connect for Enterprise Linux 6.4 - x86_64                           3
core-0                     core-0                                                              4011
dell-el6                   dell-el6                                                            2318
repolist: 28015

Then just install the connect-client package:

$ yum install connect-client

... and you're all set!

Without environment modules

If your site does not have environment modules or RPM/Yum, install the package from source. This is much the same as above, but you only need one destination directory:

$ ./install.sh /software/connect-client

or even:

$ ./install.sh /usr/local

If necessary, modify the $PATH:

$ export PATH=/software/connect-client/bin:$PATH

You can safely install Connect Client to a common location such as /usr or /usr/local. The installation script will also install the modulefile (which you won't need) but you can simply remove it.
