Create a user named "globus". This non-privileged user will be used to perform administrative tasks such as starting and stopping the container, deploying services, etc. Pick an installation directory, and make sure this account has read and write permissions in the installation directory.

	Tip
	You might need to create the target directory as root, then chown it to the globus user: # mkdir /usr/local/globus-4.1.2.1 # chown globus:globus /usr/local/globus-4.1.2.1

	Important
	If for some reason you do not create a user named "globus", be sure to run the installation as a non-root user. In that case, make sure to pick an install directory that your user account has write access to.

Download the required software noted in Software Prerequisites for Installing GT 4.1.2.

	Tip
	Be aware that Apache Ant will use the Java referred to by JAVA_HOME, not necessarily the first Java executable on your PATH. Be sure to set JAVA_HOME to the top-level directory of your Java installation before installing. Also, check the Platform Notes for GT 4.1.2 if your OS includes ant already. Your /etc/ant.conf is probably configured to use gcj, which will fail to compile the Toolkit.

In this guide we will assume that you are installing to /usr/local/globus-4.1.2.1, but you may replace /usr/local/globus-4.1.2.1 with whatever directory you wish to install to.

As the globus user, run:

globus$ export GLOBUS_LOCATION=/usr/local/globus-4.1.2.1
globus$ ./configure --prefix=$GLOBUS_LOCATION

You can use command line arguments to ./configure for a more custom install. Here are the lines to enable features which are disabled by default:

Optional Features:
 --enable-prewsmds       Build pre-webservices mds. Default is disabled.
 --enable-wsgram-condor  Build GRAM Condor scheduler interface. Default is disabled.
 --enable-wsgram-lsf     Build GRAM LSF scheduler interface. Default is disabled.
 --enable-wsgram-pbs     Build GRAM PBS scheduler interface. Default is disabled.
 --enable-i18n           Enable internationalization. Default is disabled.
 --enable-drs            Enable Data Replication Service. Default is disabled.
 [...]
Optional Packages:
 [...]
 --with-iodbc=dir        Use the iodbc library in dir/lib/libiodbc.so.
Required for RLS builds.
 --with-gsiopensshargs="args"
 Arguments to pass to the build of GSI-OpenSSH, like
 --with-tcp-wrappers

For a full list of options, see ./configure --help. For a list of GSI-OpenSSH options, see Optional Build-Time Configuration for GSI-OpenSSH. For more information about our packaging or about choosing a flavor, see Packing Details for Installing GT 4.1.2.

Run:

globus$ make

Note that this command can take several hours to complete. If you wish to have a log file of the build, use tee:

globus$ make 2>&1 | tee build.log

The syntax above assumes a Bourne shell. If you are using another shell, redirect stderr to stdout and then pipe it to tee.

	Note
	Using make in parallel mode (-j) is not entirely safe, and is not recommended.

Finally, run:

globus$ make install

This completes your installation. Now you may move on to the configuration sections of the following chapters.

We recommend that you install any security advisories available for your installation, which are available from the Advisories page. You may also be interested in subscribing to some mailing lists for general discussion and security-related announcements.
