Which CentOS version is my appliance using

New installations of BMC Discovery 11.3 run on CentOS 7. The upgrade to BMC Discovery 11.3 from 11.1 and earlier versions replaces Red Hat Enterprise (RHEL) Linux 6 with CentOS 6.

CentOS is an enterprise-class Linux platform that is derived from, and aims to be functionally compatible with its upstream source, RHEL. Because of this compatibility, BMC performs the same CentOS testing against the Red Hat 6 STIGs.

When applying OS upgrades to BMC Discovery 11.3, ensure that you download and apply the correct CentOS operating system upgrade.

Which version am I using?

To determine whether your appliance is running on CentOS 6 or CentOS 7, check the footer of any UI page. The BMC Discovery version number, build number, and OS version are provided on the bottom line.

Alternatively, from the command line, enter:

tideway@appliance01 ~]$ cat /etc/centos-release

  • For CentOS 6 the output begins:
    CentOS release 6.x
  • For CentOS 7 the output begins:
    CentOS Linux release 7.x
