------------------------------------------
Summary: Data Node Start issue on non-root install
Key: AMBARI-9110
URL: https://issues.apache.org/jira/browse/AMBARI-9110
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
Fix For: 2.0.0
DataNode cannot start due to an Operation not permitted when trying to change
the ulimit. See screenshot.
Non-Root Setup:
{noformat}
# vipw
root:x:0:0:root:/root:/sbin/nologin
# echo > /etc/securetty
# vi /etc/ssh/sshd_config
PermitRootLogin no
{noformat}
With that done I created a user named ‘ambari’ and used that during setup for
the non-root user to run the Ambari Server as. I’ve setup this in /etc/sudoers:
{noformat}
ambari ALL=(ALL) NOPASSWD: ALL
{noformat}
I know this is best case for privileges, but want to get through one iteration
before tightening it up.
As well as this in /etc/sudoers.d/ambari (0440)
{noformat}
Defaults exempt_group = ambari
Defaults !env_reset,env_delete-=PATH
Defaults:ambari !requiretty
{noformat}
