Installing Arenadata Streaming with Ambari 2.7.0

Installing the Ambari 2.7.0 server goes through several steps:

Setting up a remote YUM repository

Setting up a remote repository is no different from setting up any additional repository YUM. To add a repository, you must run the following command as root:

yum-config-manager –-add-repo

Install Ambari Server

The Ambari server is installed from the RPM package using the YUM command:

yum install ambari-server

The command sets the Ambari server which is the web application server to the port 8080. Also installed is the server instance PostgreSQL on port 5432.

Ambari Server setup

Ambari server must be configured to work correctly. If the instance PostgreSQL is configured on the default port you should run the following command:

ambari-server setup

During the setup process you must specify or accept the default settings:

  • User account – you can choose any account to start the Ambari server (it is not necessary to log in from root). If the user does not exist, it is automatically created;

  • Java JDK – to download Oracle JDK 1.8, you must enter the value 1 and accept the license Oracle JDK to download files from Oracle. The installation of JDK is done automatically;

  • Database – select database:

    Enter advanced database configuration

    At the command line you must answer n or y:

    • n – for use with Ambari standard built-in database PostgreSQL. By default, the database name PostgreSQL is set to ambari and the login/password is ambari/bigdata;
    • y – if you want to use with Ambari an existing PostgreSQL database, MySQL or Oracle instead of the default one. Next, for the selected database you must specify the connection parameters.

Start Ambari Server

After installing the Ambari server start is performed by the command:

ambari-server start

To check the server status use the command:

ambari-server status

To stop the server use the command:

ambari-server stop

Ambari server is available on port 8080. By default it is set to the following account:

  • User: admin
  • Password: admin


It is recommended to change the password after the first login

To enter the web interface Ambari you need to specify the server address in the address bar of the browser:

http://<адрес сервера>:8080

This requests a login and password. After authorization opens the web interface Ambari (Pic.45.).
