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. SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
