Red Hat Enterprise Linux 7 (RHEL 7) is supported for SAS^® 9.4M0 (TS1M0) and later with the following restrictions:

• Only SAS 9.4 is supported with RHEL 7. No earlier release of SAS is supported with RHEL 7.
  
  
• You must install the compat-glibc and libpng12 libraries in order to launch SAS 9.4 on RHEL 7.

The command to install these libraries is:

yum install compat-glibc libpng12

• If you are installing SAS 9.4 on RHEL 7.4, you must install the dejavu-serif-fonts library in order to be able to launch the SAS Deployment Manager or SAS Deployment Wizard.

The command to install this library is:

yum install dejavu-serif-fonts

The reason for this requirement is documented by Red Hat: https://access.redhat.com/solutions/3145721

• With RHEL 7, the default storage location of Kerberos credential caches has changed.
  SAS customers who use Kerberos authentication must configure Kerberos for the previous behavior and use file-based caches stored in /tmp.
  
  Documentation can be found in the Linux man page for krb5.conf. Search for the term default_ccache_name.
  
  
• SAS^® Grid Manager customers who use GFS2 and want to upgrade to RHEL 7 should upgrade to RHEL 7.1 or a later minor release.
  
  Performance concerns related to GFS2 on RHEL 7.0 exist, but RHEL 7.1 is fully supported.
  
  
• SAS Grid Manager customers must install a version of Platform Suite for SAS^® that includes LSF 9.1.1 (that is, Version 8.1 or later). Version 8.1 is shipped with SAS^® 9.4M2 (TS1M2).
  
  If you have installed SAS 9.4M0 or SAS^® 9.4M1 (TS1M1), you must upgrade to SAS 9.4M2 or later. Alternatively, contact SAS Technical Support to obtain Version 8.1.
  
  
• The use of IBM Platform RTM with SAS on RHEL 7 requires a Platform RTM for SAS patch.
  
  SAS Grid Manager customers who run Platform RTM for SAS must install the patch or continue to run this component on a supported version of RHEL.
  
  
• The SAS^® High-Performance Computing Management Console does not properly handle CGROUPS when running on RHEL 7.
