Create a load balancing virtual server
The cache redirection virtual server on the NetScaler appliance can send requests to either a cache server farm, if the request is cacheable, or to the origin server farm if the request is not cacheable.
Each cache server is represented on the appliance by a service, which is bound to a load balancing virtual server that receives requests from the cache redirection virtual server and forwards those requests to the servers.
For details on configuring load balancing virtual servers and other configuration options, see “Load Balancing.”
Create a load balancing virtual server by using the CLI
At the command prompt, type the following commands to create a load balancing virtual server and verify the configuration:
- add lb vserver <name> <serviceType> [<IPAddress>] [<port>] - show lb vserver [<name>]
> add lb vserver Vserver-LB-CR HTTP 10.102.20.30 80 Done > show lb vserver Vserver-LB-CR Vserver-LB-CR (10.102.20.30:80) - HTTP Type: ADDRESS State: DOWN Last state change was at Fri Jul 2 08:47:52 2010 Time since last state change: 0 days, 00:00:08.470 Effective State: DOWN Client Idle Timeout: 180 sec Down state flush: ENABLED Disable Primary Vserver On Down : DISABLED Port Rewrite : DISABLED No. of Bound Services : 0 (Total) 0 (Active) Configured Method: LEASTCONNECTION Mode: IP Persistence: NONE Vserver IP and Port insertion: OFF Push: DISABLED Push VServer: Push Multi Clients: NO Push Label Rule: none Done
Create a load balancing virtual server by using the GUI
Navigate to Traffic Management > Load Balancing > Virtual Servers.
In the details pane, click Add.
In the Create Virtual Server (Load Balancing) dialog box, specify values for the following parameters as shown:
- IP Address*- IPAddress
*A required parameter
In the Protocol list, select a supported protocol (for example, HTTP). If the virtual server is to receive traffic on a port other than the well-known port for the selected protocol, enter a new value in the Port field.
Click Create, and then click Close. The Load Balancing Virtual Servers pane displays the new virtual server.
