Ambari install failed

yebinianhi — Sun, 18 Aug 2019 00:40:38 GMT

Hi ALL,

I installed Ambari on Amazon EC2 with three virtual machines.

ubuntu16.4

I followed the guide from:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-installation/content/download_the_ambari_repo_ubuntu16.html

But, I got the following error:

I cam confirm that:

Ambari-agents are running on all hosts.

/etc/ambari-agent/conf/ambari-agent.ini are correct.

ssh working fine.

I don't know I missed?

Is the one that succeeded, running on the same host as the ambari-server? Perhaps there is no route to the server from the agents.

Yes, the succeeded one is the one run as the server. Could you tell me how to route to the server?

Many thanks,

@Bin Ye

Can you please check if there is any firewall which is blocking connections on port 22? You can also try to register agents manually by installing ambari-agent on each machine --> editing /etc/ambari-agent/conf/agent.ini --> point it to correct ambari-server hostname --> select manual registration at the time of agent registration in Ambari.

Hope this helps.

1. make sure your ntpd, it need runing on all hosts. ntpd status and ntpd start

2. check your selinux file if SELINUX=disabled

3. your /etc/hosts file include all host privte ip and public ip. i.e. ip-..... ec2... 10.23.24.234

4. disable the iptables, service iptables stop. or systemctl stop firewall

5. reboot machine and make sure ntpd status is active.

this worked for me all the time. you need to clikc on the 'check here for warnings' to see exact info.
