This article introduces the relevant knowledge of "installation and use of ambari on centos7". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. There are three centos7, whose names are ws11.localdomain, ws12.localdomain and ws13.localdomain. Configure the epel source (install epel-release).

2. Configure root user ssh password-free access.

3. Install ntp timing service.

4. Turn off the firewall. Use firewalld under centos7.

5. Close selinux. Setenforce 0There is a modification of SELINUX=disabled in the selinux config.

6. Download repo from http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.1.2.1/ambari.repo and put it in / etc/yum.repos.d.

7. Ws13, as a server, provides web management interface. Install ambari-server on ws13. Yum install ambari-server .

8. Install ambari-agent on all slave nodes ws11, ws12, and ws13. Yum install ambari-agent . (in theory, ambari-agent can be automatically installed on each node by the later ambari-server setup, but the network speed is not good and it is easy to fail.)

9. Execute ambari-server setup [- j JAVA_HOME-v] on server, and you will be prompted to install jdk. If the network speed is not good, the download will fail. You can download jdk-7u67-linux-x64.bin manually and put it under / var/lib/ambari-server/resources/. Then you will be prompted for the database for the configuration, and selecting n will press the default configuration. (database type: postgresql database: ambari username: ambari password: bigdata)

10. Start Ambari Server. Ambari-server start .

You can log in to the page through http://ws13:8080. User name: admin password: admin.

12. Configuration file / etc/ambari-server/conf/ambari.properties, / etc/ambari-agent/conf/ambari-agent.ini. =

When you deploy components later, downloading from the Internet is still slow, and you can consider installing them from a local source.
