Multi-Server Install

Overview

A multi-server install is the default install configuration used in production environments. The usual configuration is one Presentation server, one Database server, one Elasticsearch Database server, and one or more Collection servers, however, a single server can have one or more roles associated to it. This means that it is also possible to setup a combination Presentation/Database server and then one or more Collection servers, or a combination Presentation/Collection server with a separate Database server, etc.

See the Understanding Server Roles documentation for additional information around roles that are available.

Dependencies

Steps

Preparation

  1. Get the collection file and place it in the /opt/install/ directory on the server. (Create the directory, if it does not already exist.)

  2. Extract the contents of the collection to the /opt/install/ directory:

    unzip -d /opt/install/ Oracle-Communications-Unified-Assurance-6.W.X.Y.Z.zip

  3. Install the RPM on the server using the following syntax. By default, this will install Unified Assurance into the /opt/assure1/ directory:

    yum install /opt/install/Assure1-6.V.W.X.Y-ZZZ.x86_64.rpm

    Note:

    Unified Assurance can be installed to a different directory by using the "rpm" installation command with the "prefix" flag.

    WARNING:

    Using the "rpm" command will not automatically install the required dependencies, and some dependency errors may come up if using this method. Install the missing dependencies, then install again using the "rpm" command.

    An example is shown below which will place the files in the "/opt/a1/" directory:

    rpm -ivh --prefix /opt/a1 /opt/install/Assure1-6.V.W.X.Y-ZZZ.x86_64.rpm

  4. Do one of the following before running SetupWizard.

    • Export the LD_LIBRARY_PATH:

      export LD_LIBRARY_PATH=$A1BASEDIR/lib

    • or source the .bashrc file:

      source $A1BASEDIR/.bashrc

Base Installation

Presentation Server

  1. The SetupWizard for installing Unified Assurance is located in the $A1BASEDIR/bin/ directory. Go to the directory:

    cd $A1BASEDIR/bin/

    Note:

    The default $A1BASEDIR is /opt/assure1/. This may be different if a custom path was used in the preparation step.

  2. Run the SetupWizard to begin the installation. The SetupWizard command must be run as root and must include the --Depot flag:

    ./SetupWizard --Depot /opt/install/:a1-local

  3. When prompted Is this your Primary Presentation Server?, enter y and press Enter.

  4. When prompted What is this install's Web FQDN? [FQDN]:, make a change if needed, then press Enter.

  5. When prompted Comma-delimited list of roles to install (numeric):, enter the numerical values for the following roles, and then press Enter:

    • Presentation

    • Processing

      Note:

      The "Processing" role is installed on the presentation server to split the overall load across the servers in the environment. While it is not required to be on the presentation server, it will still need to be installed on a server somewhere in the environment. If the applications run as part of this role become too much for the server, the role may need to be migrated to be on a dedicated system.

  6. When prompted Do you accept all the license agreements? Must type "AGREE":, enter AGREE and press Enter.

  7. The files needed for the installation will then be downloaded and installed.

  8. The following log files can be checked for errors that may have occurred during the install:

    • $A1BASEDIR/logs/SetupWizard.log

    • $A1BASEDIR/logs/Package.log

  9. Enter the web-FQDN of the server into your browser to open up the UI login page. Login with:

    • Username: admin

    • Password: admin

  10. Navigate to the Users UI and select the admin user account.

    Configuration -> AAA -> Users

    Note:

    As a best practice, it is advised to update/change the administrator password to a password of your choosing.

Database Server

  1. The SetupWizard for installing Unified Assurance is located in the $A1BASEDIR/bin/ directory. Go to the directory:

    cd $A1BASEDIR/bin/

    Note:

    The default $A1BASEDIR is /opt/assure1/. This may be different if a custom path was used in the preparation step.

  2. Run the SetupWizard to begin the installation. The SetupWizard command must be run as root:

    ./SetupWizard

  3. When prompted Is this your Primary Presentation Server?, enter n and press Enter.

  4. When prompted Enter the Host FQDN of your Primary Presentation Server:, enter the host FQDN of the server, then press Enter.

  5. When prompted Enter the Web FQDN of your Primary Presentation Server:, enter the web FQDN of the server, then press Enter.

  6. When prompted Set Web FQDN for this server?, enter n and press Enter.

  7. When prompted Is this a redundant server?, enter n and press Enter.

  8. When prompted Comma-delimited list of roles to install (numeric):, enter the numerical values for the following roles, and then press Enter:

    Note:

    Depending on the load per database, the different database roles can be installed on separate servers. One possible combination are the Event and Graph databases can be put on the same server while keeping the Metric database separate, but larger organizations may need to keep all three separate.

    • Database.Event

    • Database.Graph

    • Database.Metric

  9. When prompted Do you accept all the license agreements? Must type "AGREE":, enter AGREE and press Enter.

  10. The files needed for the installation will then be downloaded from the presentation server and installed.

  11. The following log files can be checked for errors that may have occurred during the install:

    • $A1BASEDIR/logs/SetupWizard.log

    • $A1BASEDIR/logs/Package.log

Elasticsearch Database Server

    Note:

    The default $A1BASEDIR is /opt/assure1/. This may be different if a custom path was used in the preparation step.

  2. Run the SetupWizard to begin the installation. The SetupWizard command must be run as root:

    ./SetupWizard

  3. When prompted Is this your Primary Presentation Server?, enter n and press Enter.

  4. When prompted Enter the Host FQDN of your Primary Presentation Server:, enter the host FQDN of the server, then press Enter.

  12. The AnalyticsWizard for installing analytics is located in the $A1BASEDIR/bin/historical/ directory. Go to the directory:

    cd $A1BASEDIR/bin/historical/

  13. Run the AnalyticsWizard to begin the installation. The AnalyticsWizard command must be run as root:

    ./AnalyticsWizard

  14. When prompted Allow this script to configure for analytics? [n]:, enter y and press Enter.

  15. When prompted What heap size should Elasticsearch use? [<value>]: , make a change if needed, then press Enter.

    Note:

  16. When prompted What maximum machine learning size should Elasticsearch use (percent of system memory)? [60]:, make a change if needed, then press Enter.

  17. When provided information about analytics components and a list of servers, then prompted Are these servers correct? [n]:, generally speaking, the values should be like this:

    • Analytics UI: This should be the presentation server.

    • Analytics DB: This should be the database server with the "Database.Historical" roles.

    • Importer: This should be the database server with the "Database.Historical" roles.

    If the servers listed are correct, enter y and press Enter, otherwise, enter n and press Enter. The servers listed for each role can be changed, if necessary.
