Hi, I Have trying to install kerberos on my HDP 2.6 sandbox,

[#1]

My problem is that I've been following a lot of documents that can help me with installing, and after finishing all the steps,I've found that krb5kdc or kadmin is not running / enabling. for example when i type " service kadmin start " or " service krb5kdc start" command. its doesnt do /show me anything. i tried many other commands " systemctl start krb5kdc" or " systemctl enable krb5kdc". So does anyone knows what is the problem.

PS. the last document that I've been following is this video : https://www.youtube.com/watch?v=-pBh7fgV6w4&t=434s

Please try this:

1. Make sure that you have logged in to Sandbox SSH shell only at port 2222

# ssh root@localhost -p 2222
Enter Password: hadoop

2. Please make sure to disable the Sandbox Dev Yum repo by setting "enabled=0" as following: (to know why we should do this please refer to: https://community.hortonworks.com/questions/143887/problem-installing-ambari-metrics-collector.html)

# cat /etc/yum.repos.d/sandbox.repo
[sandbox]
baseurl=http://dev2.hortonworks.com.s3.amazonaws.com/repo/dev/master/utils/
name=Sandbox repository (tutorials)
gpgcheck=0
enabled=0

3. Please perform a Yum cleanup

# yum clean all

4. Now you will need to install the following packages:

# yum install krb5-server krb5-libs krb5-workstation -y

5. Then perform the "/etc/krb5.conf" edits based on your requirement.

6. Create Kerberos Database by running the following command (Please remember the value which you are going to enter for the "master key". I entered "master" )

# kdb5_util create -s

7. Start the KDC server and the KDC admin server as following:

# /etc/rc.d/init.d/krb5kdc start
# /etc/rc.d/init.d/kadmin start
