CCM_PRIMARY – Configure HA Wizard Properties

To configure high availability for CCM_SA_PRIMARY, follow this procedure.

  1. Invoke the CCM wizard as a root user (see Virtual Appliance Process > Cloud-Specific Setup Details for a sample setup).

    Wizard Path
    /usr/local/cliqr/bin/ccm_config_wizard.sh
  2. Configure the HA properties.

    Write this down for future reference!

    Write down the Field details in a printed version of the Installation Approach > Your Notes section for later use.

    This section ONLY provides the HA details for EMPHASIS – In addition to this HA information, you must also configure the generic information in the remaining CCM details provided in the table identified by the Configure CCM Wizard Properties title.

    Field

    Description

    DB – Configure Database



    DB IP or Hostname

    The VIP/EIP for the master database and slave database. See Phase 1: Prepare Infrastructure > Cloud Nuances for additional context.

    When you configure the MGMTPOSTGRES_MASTER – Configure High Availability Properties, you would have configured the VIP/EIP address for the db_config_wizard already. Similarly, you must provide the EIP/VIP address for the CCM_SA_PRIMARY and the CCM_SA_SECONDARY servers.

    DB Username
    and
    DB Password

    The following credentials are pre-populated:

    • Default username = cliqr (can be changed – manually change the password on MGMTPOSTGRES VMs or RDS and then update the username in the CCM through the database config wizard.

      Be sure to change the PostgresDB password and update the db.properties file to reflect the correct password.

    • Default password = cliqr (can be changed)

      Be sure to change the default password immediately after your first login. See PostgreSQL Password for additional context.

    Configure_HA


    Primary Node Private IPThe IP address of the primary CCM VM
    Secondary Node Private IP The IP address of the secondary CCM VM

    Mgmtserver DNS Name

    Use the DNS or IP of the CCM_LB – Used by the CCO VM to communicate with the CCM VM.

    Configure CCM Wizard Properties

    To configure the CCM wizard properties, follow this procedure.

    1. Invoke the CCM wizard as a root user (see Virtual Appliance Process > Cloud-Specific Setup Details for a sample setup).

      CCM Wizard Path
      /usr/local/cliqr/bin/ccm_config_wizard.sh
    2. Configure the server properties.

      Write this down for future reference!

      Write down the Field details in a printed version of the Installation Approach > Your Notes section for later use.

      Wizard Menu

      Field

      Description

      Server_Info – Configure Server Info (Required)

      Mgmtserver DNS Name

      DNS (or IP address) of the CCM management server.

      If you are configuring the HA environment, enter the CCM_LB DNS (or IP) in this field.

      DB – Configure DatabaseIP or Hostname

      DNS or IP of the database.

      DB Username and Password

      The following credentials are pre-populated:

      Default username = cliqr (cannot be changed)

      Default password = cliqr (must be changed)

      Be sure to change the default password immediately after your first login. See PostgreSQL Password for additional context.

      ELK_Info –  Configure Log Collector InfoELK Host

      Specify the IP address for the Log Collector host.

      Elasticsearch PortDisplays 8881 by default.
      Kibana PortDisplays 8882 by default.
      ELK UserThe default ELK Username = logreader.
      ELK PasswordThe default ELK Password is re@d0nly (zero between d and n) (change this password after the initial login – see Download Log File for additional context).
      Host Identifier

      A Unique ID for the server – be sure to prefix the unique identifier with CCM_ for example, CCM_1
      If not set, the CloudCenter platform uses the CCM server date.

      The Host Identifier cannot contain capital letters for both CCM and CCO configurations.

      Host Identifier List

      Only applies to environments using the HA mode – provide a list of comma separated unique host identifiers for all Log Collector hosts in a HA setup = for example, CCM_1,CCM_2,myCCM.

      The Host Identifier List cannot contain capital letters for both CCM and CCO configurations.

      In an environment operating in HA mode, if you have two CCM instances with unique IDs configured as CCM_1,CCM_2 in their respective server.properties file, then this property should state CCM_1,CCM_2 in both CCM instances. Each CCM must be aware of the unique ID of the other CCM(s) when in HA mode.

      Custom Certs Menu
      Generate_CertsTo generate new certificates for CloudCenter components. See Certificate Authentication > Generate and Update the certs.zip File on the CCM for additional context.
      Update_CertsTo update certificates for CloudCenter components. See Certificate Authentication > Generate and Update the certs.zip File on the CCM for additional context.
    3. Exit the CCM configuration wizard.

    4. Select Yes, to restart the CCM server and corresponding CloudCenter services.

    You have successfully installed the CCM instance! You can now proceed to the next step:

    • Configure the Log Collector details in the CCM wizard's Configure Log Collector Info menu.

    • If you are installing the Enterprise Service Bus (ESB), do so at this point.

    Back to: CCM (Required)

  3. Once the details are entered, the database server begins replication configuration between the database servers followed by HA configuration and finally presents the following status messages.

    • Configuring CCM HA ...
    • Restart server (with the progress bar)
    • Configured CCM HA successfully
  4. Restart the secondary CCM server and corresponding CloudCenter services.
  5. Exit the CCM configuration wizard.
