Linux at SLAC
UNIX at SLAC
|Updated: 28 Mar 2013|
SLAC's recommended Linux for all machines is Red Hat Enterprise Linux (RHEL). Currently, two versions of RHEL are supported, RHEL6 and RHEL5.
RHEL is available for both 32-bit (IA-32) and 64-bit (x86-64) architectures. RHEL6 or RHEL5 are the recommended versions for new installs. Note that software built under RHEL6 will not run on a RHEL5 system; likewise, software built on a RHEL6/64-bit system won't run on a RHEL6/32-bit machine.
RHEL4 and earlier versions of RHEL are not permitted at SLAC.
SLAC has negotiated a site subscription to RHEL and has also purchased a support contract from Red Hat, which has proven quite valuable. In addition to helping us resolve a number of problems it has also given us early access to new releases and a voice in Red Hat's future directions.
The following are explicitly not supported:
|RHEL 5||2.6.18-348.3.1.el5||2.5-107||RHEL 5.9|
|RHEL 6||2.6.32-358.2.1.el6||2.12-1.107.el6||RHEL 6.4|
All earlier versions of the kernel or glibc are explicitly prohibited.
Once you have installed Linux on your system, we strongly recommend that you also install taylor, the OCIO tool for maintaining UNIX and Linux systems. Instructions for installing taylor are included with the OS installation instructions in the Web pages referenced above. Among other things, taylor will automate the process of regularly applying operating system updates.
Please note that if you cannot run taylor (e.g., because you are using some other Linux distribution), or do not choose to run it, you are still responsible for maintaining your system. This includes but is not limited to such things as:
