How to Prepare for a Data Aggregator Installation

Meet the following prerequisites before installing Data Aggregator:

  1. Verify that Data Repository is set up and running.
  2. Open both port numbers 8581 and 61616 on the Data Aggregator system. Remote access is required to this port.

    Note: You can change the 61616 port number to another port after you install Data Aggregator.

  3. Verify that Security Enhanced Linux (SELinux) is disabled on the computer where you are going to install Data Aggregator. By default, some Linux distributions have this feature enabled, which does not allow Data Aggregator to function properly. Disable SELinux or create a policy to exclude Data Aggregator processes from SELinux restrictions.

    Note: For information about configuring an SELinux security policy, see the Red Hat documentation.

  4. Verify that the directory where you are going to install has write privileges for your Data Aggregator user.
  5. Ensure that the user that is installing Data Aggregator has a ulimit value of at least 65536.
  6. (Optional) Configure the sudo user account.
  7. Configure UTF-8 support.
  8. Review the installation considerations.
