Question

Clustered IIS on Server 2003

Asked by: titanmike

I have searched the database here and googled already and most (if not all) answered referring to the NLB Documentation from Microsoft.
But I also read that Microsoft says you supposed to use the "general script" resource on a Microsoft Cluster in order to cluster the IIS service but doesn't give more info in how to and how it works in general.

So my question is now : Do you NEED NLB in order to cluster a simple website ? The location of the website can obviously be on a storage resource, but what about the settings etc. ?

I know there are thousands of pages available on microsoft.com - but I hope someone has a simple how to as I might need to do this in a hurry :(

Cluster and NLB are two different things.
In order to cluster websites in IIS you must install IIS to all nodes partecipating in Cluster (MSCS), define the website(s) as virtual directory that resides on the shared storage to all nodes and cluster the service pointing to the .vbs file that comes with the IIS installation (same for FTP)
NLB doesn't need shared storage but it does need manual allignment of the website contents as each NLB node has it's own web site and web content locally.

You don't need NLB to cluster (MSCS) a website and NLB IS NOT supported on Cluster (MSCS).

Ah good because apparently they don't want NLB

So I need to create the website on both nodes and create a service resource ?
What do you mean with pointing the service to the vbs ?

I must admit - I never used IIS in a clustered environment :(

Great - seems like you need to search for failures rather than solutions in order to find a guide http://support.microsoft.com/kb/887417

Have a look at the following link please:

http://technet2.microsoft.com/WindowsServer/en/library/88d15b46-0011-4c87-bfc5-aa6d989b3e941033.mspx?mfr=true

It's quite explicative. In Windows 2003 clustering IIS 6.0 goes through the creation of a Generic Script resource. In the systemroot\system32\inetsrv path you'll find the iis_switch.vbs.

(Don't bother about the upgrading stuff, it's only for those who upgrade a Windows 2000 server to Windows 2003).

Let us know if that's ok.

I just tried it but it doesn't seem to work .. basically when the cluster fails over the default site on the 2nd node shows. To make it work I had to re-create the site on the 2nd node using the website folder on the shared disk which makes the whole script pretty much pointless

 

by: titanmikePosted on 2008-05-20 at 17:14:22ID: 21611314

Ok, never mind. It does actually work - I didn't know that the script doesn't do anything but starting the www service in case it is stopped.

So yea - kinda pointless ...

 

by: titanmikePosted on 2008-05-20 at 17:15:00ID: 21611317

Oh and you don't use the iis_switch.vbs but clusweb.vbs ...
