Installing Zimbra on Ubuntu 10.04 Amazon Ec2

[lanks]

Hello

I am trying to install Zimbra on Ec2 with no luck. I am seeing all sorts of different configurations but I can't get anything to work.

Basically I need help with configuring all the DNS, hostname settings etc. before I can install Zimbra.

So if I have a fresh brand new instance of Ubuntu 10.04 64bit what do I need to configure to get all the host names / dns settings correct? And in what order should I configure them? And what should these configurations be configured as?

Thanks
Liam

Details of what's required are covered in the Quick Start Installation Guide.

Go to the Split DNS article and read that, it has full details of what's necessary (as do many forum threads).

I just finished an (amalgamated) tutorial on how I managed to get this working.

Seems that the some people had issues with the ec2 dhcp client overwriting the resolv.conf file configuration:

Here's a possible resolution:

Edit the /etc/dhclient.conf file (create one if it doesn’t exist) to look like the following:

supersede domain-name "yourdomain.com" ;
prepend domain-name-servers xxx.xxx.xxx.xxx ;my internal EC2 IP address

Where xxx.xxx.xxx.xxx represents your EC2′s internal IP address (e.g. 10.x.x.x)

Next, run the following command to force the changes (if need be).

$ dhclient -r ; dhclient

After doing this, check your /etc/resolv.conf file to ensure the changes have indeed been made.

The resolv.conf settings should now remain permanent, and persist during normal daily operation of your Zimbra server.
