5.7. Disable SELinux and PackageKit and check the umask Value

  1. SELinux must be temporarily disabled for the Ambari setup to function. Run the following command on each host in your cluster:

    setenforce 0
  2. On the RHEL/CentOS installation host, if PackageKit is installed, open /etc/yum/pluginconf.d/refresh-packagekit.conf with a text editor and make this change:


    PackageKit is not enabled by default on SLES. Unless you have specifically enabled it, you do not need to do this step.

  3. Make sure umask is set to 022.
