Set Up a Load Balancer for Orchestrator Clustering › NGINX Load Balancer › Basic Communication › Windows

Windows

Follow these steps:

1. Navigate to the following folder.

   nginx_install_dir/conf
   

   This folder contains pam-server.conf file.

2. Open the pam-server.conf file.
3. There are four code blocks that require editing for every node that you add.
   1. Add the node1 host name in the upstream loadbalancer block:

      server <Enter node1 hostname here>:<http port> max_fails=3 fail_timeout=3s
      

      Note: Defines the HTTP port that is used for the web server if the Support Secure Communication check box is cleared. This port is part of the URL that is used to access CA Process Automation web services and the CA Process Automation login screen.

   2. Add the node1 host name under the upstream jettyloadbalancer block.

      server <Enter node1 hostname here>:<server port> max_fails=3 fail_timeout=3s
      

   3. Add the node1 host name under the Define node1 block:

      server <Enter node1 hostname here>:<server port> max_fails=1 fail_timeout=3s
      

      Note: Defines the port that the Domain Orchestrator uses to communicate with other Orchestrators and agents.

   4. Add the node1 host name under the upstream uiloadbalancer block:

      server <Enter node1 hostname here>:<http port> max_fails=3 fail_timeout=3s
      

   Replace the Enter node1 hostname here placeholders with a valid value. Do not change the port numbers unless you use a different port for the CA Process Automation node. By default, the http port is configured to 8080 and the server port is configured to 80.

   Note: The valid values are the IP address, the FQDN, or the DNS alias that resolves to the host where you are installing the initial Domain Orchestrator node. The valid value is the same value that is used for “Server Host” when installing the Domain Orchestrator.

   Repeat these steps for each additional node that you install.

4. Save and close the pam-server.conf file.
5. Open the nginx_install_dir/conf/nginx.conf file.
6. Add the following entry in the http block at the end of nginx.conf file:

   include nginx_install_dir/conf/pam-server.conf;
   

   This entry links NGINX with the configuration changes you made for CA Process Automation in the pam-server.conf file.

7. Save and close the nginx.conf file.

   Important! Perform the rest of these steps after you install at least one Orchestrator node. See Interactive Domain Orchestrator Installation or Unattended Domain Orchestrator Installation for instructions.

8. Stop NGINX. In a command prompt, navigate to the NGINX directory location and enter:

   nginx -s stop
   

9. Restart NGINX.

   The changes take effect.
