Ambari Server

Setup​

sudo yum install -y ambari-server

Configuration​

Before starting the Ambari server, you need to configure it.

The installer configures Ambari to communicate with the Ambari database, installs the JDK, and allows you to customize the user account under which the Ambari server daemon will run.

The following command handles the configuration process. Run the following command on the Ambari server host to start the configuration process. You can also add configuration options to the order.

sudo su -
ambari-server setup

The following options are frequently used for Ambari server configuration.

-j | --java-home​

Specifies the JAVA_HOME path to use on the Ambari server and all nodes in the cluster.

By default, when you do not specify this option, the Ambari Server configuration downloads the Oracle JDK 1.8 binary and associated Java Cryptography Extension (JCE) policy files to /var/lib/ambari-server/resources. Ambari Server then installs the JDK in /usr/jdk64.

This path must be valid on all nodes. For example :

ambari-server setup –j /usr/java/default

--jdbc-driver​

This should be the path to the JDBC driver JAR file. Use this option to specify the location of the JDBC driver JAR and to make this JAR available on the Ambari server for distribution to cluster hosts during configuration. Use this option with the --jdbc-db option to specify the database type.

--jdbc-db​

Specifies the database type. Valid values ​​are: [postgres | mysql | mariadb] Use this option with the --jdbc-driver option to specify the location of the JDBC driver JAR file.

-s | --silent​

The installer runs silently. Accepts all default prompt values, such as:

  • root user account for the Ambari server.
  • Oracle 1.8 JDK (installed in /usr/jdk64). This can be overridden by adding the -j option and specifying an existing JDK path.
  • Integrated PostgreSQL for Ambari DB (with database name "ambari").

--enable-lzo-under-gpl-license​

Use this option to download and install LZO compression, which is subject to the General Public License.

-v | --verbose​

Prints detailed information and warning messages to the console during installation.

-g | --debug​

Prints debug information to the console during installation.
