5.5. Disable SELinux

SELinux must be disabled for Ambari to function. To temporarily disable SELinux, run the following command on each host in your cluster:

setenforce 0

Permanently disabling SELinux so that on system reboot it does not restart is strongly recommended. To do this, edit the SELinux config and set SELINUX to disabled. On each host:

vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
