To deploy a new DB Server or a Web Server in an existing site, perform the following steps:
Ensure that you have administrator's privileges to access the Advanced Authentication Server Registrar and you have installed but not configured the Advanced Authentication server appliance for a new server.
Open the database port <Registrar_host_name>:5432 on your NAT/Firewall if you are deploying a DB Server.
Open the Advanced Authentication Configuration Wizard for a new installed server: https://<New_Server_host_name>.
In the first Server Mode step of the Configuration Wizard, select Existing cluster. Click Next.
In the DNS hostname step, specify the server DNS hostname in My DNS hostname. Click Next.
WARNING:You must specify a DNS hostname instead of an IP address because appliance does not support the changing of IP address.
Specify a password for the LOCAL\admin account and click Next on the Password screen.
In the Import database information step, a message Waiting for Global Master.... is displayed.
Switch to the Advanced Authentication - Administrative Portal of the Advanced Authentication Server Registrar and in the Cluster section, click Register new site.
In the Register new server window, specify the new server's host name in Server host.
HINT:If the new server is behind NAT, you can forward its port 443 on a temporary basis and enter external hostname:port. Do not forget to close the port after installation.
Select one of the following servers:
Web Server: It does not contain a database. It responds to authentication requests and connects to the DB Master database. You need more Web Servers to serve more workload.
DB Server: It provides a DB Slave database that is used for backup and fail-over. Two DB Slave servers are allowed within the site. When the DB Master is unavailable, the DB Slave node responds to the database requests. When the DB Master becomes available again, the DB Slave node synchronizes with the DB Master and the DB Master becomes the primary point of contact for database requests again.
NOTE:If you have selected the DB Server, you must copy database from Global Master. Open database port <Registrar_host_name>:5432 on your NAT/Firewall. Do not forget to close the port after installation.
Select the site to which you want to add the new server from the Add server to the site drop-down menu.
Click Register.
Switch to the new server and click Next.
If you have selected the DB Server, in the Copy database step click Copy. Wait until the database is copying from a Global Master server.
The server is automatically restarted within 60 seconds when the copying completes.
If you have selected the DB Server, switch to Advanced Authentication Server Registrar. The newly deployed server is displayed in the DB servers list. The newly deployed server is displayed in the DB servers list and may appear in red within 5 minutes after installation.
NOTE:Each of the DB servers in the list are pinged for every 5 minutes. In the case of an issue, the server is marked as red in the list and you can get the details of connectivity issues by clicking View log and replication issues by clicking Conflicts.
Close the database port <Registrar_host_name>:5432 on your NAT/Firewall if you opened it.
NOTE:You must install the new servers one at a time. Simultaneous installations may cause replication issues.
