This article mainly introduces how to use Docker to experience Ambari, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Before using yum to install Ambari, you can check the previous tutorials, but embarrassingly, recently want to install experience, I did not succeed (installation success, but failed to increase the cluster), has been stuck in the Hostname Confirm this step, query a lot of information, domestic and foreign, still not solved. But we can't stand still for this reason, and the cost of time and energy is too high. Put it another way, after all, I learned to use, although installation is very important, but at the moment, the focus is not on installation.

Official website link: https://www.cloudera.com/tutorials/sandbox-deployment-and-install-guide/3.html

The official website is already very detailed, so it won't be verbose. What I would like to share with you is that there must be many holes in the learning process. Don't be discouraged or give up just because somewhere gets stuck. Problems that can't be solved in a few days are usually difficult to solve in a short time (sometimes you may ignore some inadvertent detail), but the purpose is clear.

Add: non-Docker form, after making an adjustment, the progress has moved forward, at least in the Host this step is successful. The exact step is not very clear, and it can only be recorded.

Modification 1: delete the redundant / etc/hosts content and keep the content

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.0.4 server1.cluster.com

Modification 2: adjust the agent file: / etc/ambari-agent/conf/ambari-agent.ini to make the hostname settings consistent

Hostname=server1.cluster.com

Modification 3: adjusted the port of ambari-server, / etc/ambari-server/conf/ambari.properties
