VMware: (Version 10.0.01)
Primary cluster ip:192.168.220.102
vm1:192.168.220.103
vm2:192.168.220.104
Description: Environmental reasons, using a two-node configuration logging configuration process
InstallationOpen Service Manager in VM1 and VM2
Features---> Right---> Add features---> Tick Network Load Balancing-all the way to the next step until you finish
Role---> Right----> Add roles---> Tick Web server IIS---> The next step until the installation is complete
Note: This article is just for Network Load balancing, and if you need ASP. NET, install the corresponding version of the. NET Framework (in Windows Server 2008, you can add the. NET Framework 3.5) in the feature. Then tick the options you want when you install IIS
ConfigurationOn the VM1 machine.
Start Menu---> Administrative Tools---> Open Network Load Balancing Manager---> Network Load Balancing cluster---> right-click New
Enter the IP address of the VM1, click Connect, after successful connection
Click Next
Continue to the next step, click Add
If you enter the primary cluster IP address, click OK
Continue to the next step, cluster operation mode Select multicast
Next, complete, connect after successful display as (103 machine small icon for green)
Continue to add host to cluster on VM1
Enter the IP address of the VM2 and click Connect to complete
All the way to the next until the completion
On the VM2 machine.
Click Connect to an existing
Enter the primary cluster IP and click Connect
After the connection is complete, such as
To some of the configuration is complete: note: In the configuration of priority, according to the machine's configuration or requirements of self-tuning, cluster operation mode I will give a description in the back of the link, are old concept, do not quote! Test
1. In the VM1 and VM2 C Packing directory Nlb_test (this directory in order to establish Web site testing, directory location is not limited)
2.VM1 and VM2 Create a new index.html in the Nlb_test directory, as follows
<HTML><Head><title>192.168.220.103</title><Head><Body><H1>server:192.168.220.103</H1></Body></HTML>
<HTML><Head><title>192.168.220.104</title><Head><Body><H1>server:192.168.220.104</H1></Body></HTML>VM2
3. Create a new site Nlb_test in VM1 and VM2, and point to the nlb_test built on the C drive, with the port set to 8000 (IIS how to build the site is not explained in detail)
Access to http://192.168.220.103:8000/ and http://192.168.220.104:8000/respectively, all access to normal
Access 192.168.220.102:8000 with the primary cluster IP to display the website of VM1
Note: This access even if the test can not see the VM1 and VM2 the free switch on the machine, under the pressure of a large case can be seen
4. Stop VM1 node Nlb_test website, Access 192.168.220.102:8000, will automatically go to 104 (103 machine Small icon for the red table stop)
Even the building is complete!
OtherBecause just to record the process, little mention of the conceptual things that need to be understood can look at the following links

About the cluster operation mode, as the official description
The cluster operation mode parameter specifies whether the multicast media access control (MAC) address should be used for cluster operations. If multicast is enabled, NLB translates the cluster MAC address of the cluster adapter into a multicast address. Also ensure that the primary IP address of the cluster resolves to the multicast address as part of the Address Resolution Protocol (ARP). The adapter can now use the initial built-in MAC address that was disabled in unicast mode.
Before you enable Internet Group Management Protocol (IGMP) support, you must first enable multicast support. You can also enable IGMP support on the network adapter.
The IGMP multicast check box is used to enable IGMP support to limit switch broadcasts by restricting traffic to Network Load balancing ports only. That is, enabling IGMP support ensures that traffic to the NLB cluster passes through only those ports that serve the cluster host, not all of the switching ports.
