Join Sean Colins for an in-depth discussion in this video Installing Snow Leopard Server, part of Mac OS X Server 10.6 Snow Leopard New Features.
You get to this screen by putting the Mac OS X Server DVD into the optical drive, rebooting, and booting from the optical disc. You can do that by connecting a keyboard and holding down the Option key on your keyboard and selecting the Installation Disc. But one way or the other, you're going to get here. You're going to be presented with your language selection options and you're going to choose your language. So here we find ourselves at the Installing Mac OS X Server screen. Now this is useful because this is the first opportunity we get to go up to the Utilities folder. Before I go up there and start showing you the really cool utilities that are there, I'd like to mention something that's very important at this stage.
If you are running this installer on a machine that has important production data, stop here. Just stop. Back up your data. If you don't have your data backed up, what you're about to do next will destroy all your data and you won't be able to get it back. So, please be sure that you've got a complete backup of everything on your server before you proceed with the next steps. So let's take a look at what's inside that Utilities menu.
In the Utilities menu, we have 8 applications. The one that we're most concerned with right now, because we want to ensure the format of the disk we're installing on, is Disk Utility. So we're going to open Disk Utility, and here in the sidebar, you can see all of the different disks we have attached. Now you may notice that there is no installation DVD with a DVD symbol in this sidebar list. That's because I've done what many system engineers will do. That is, image the installation media over to a partition on a hard drive to speed the installation to a server.
It goes much, much faster spinning off a hard drive than off an optical disc. So that's why we're doing that now. But that's not the important thing. What's important right now is that we have a hard drive here that needs to be repartitioned and formatted. Now, I should mention here before we move on that you don't have to repartition your drive in order to install the server. We're only doing this because by repartitioning it, we get a fully reformatted drive. We are certain that we've dictated exactly what the partition table is going to be and on an Intel system it has to be GUID.
So we're being sure that that's right and we're also being certain that it's a Mac OS Extended (Journaled) volume. If you're positive that you're already on a GUID partition, and that you're going to be installing on a Mac OS Extended (Journaled) volume, then you really don't need to do this. All you need to do, if you do decide to proceed, please back up all of your data before you proceed to repartition or erase your hard drive. If you do decide to erase your volume, you could just click Erase and erase your volume here.
What we want to do though is we want to come over here to the device itself and click on Partition here on the right. We're going to click under Volume Scheme, we're going to click 1 Partition, and we're just going to rename this and I'm just going to name it exactly what we've already got. We're going to make sure that we're in a Mac OS Extended (Journaled) volume format, and we're also going to click on Options just to be certain. We're going to make sure that since we're on an Intel machine, we are in Snow Leopard after all, that we are in a GUID Partition Table, because this is necessary to boot an Intel system.
I'm going to click OK. When we have that done, we're going to click Apply. It's going to warn us that we're about to erase that drive. We're going to agree to that by clicking the Partition button. That's going to go ahead and partition the disk and it's going to remount it for us and here we go. So we now have our single partition hard drive here. We're going to click Disk Utility and pull down to Quit Disk Utility. We're going to continue with the installation of our server software. We are clicking Continue, agreeing to license, and then we'll be presented with this window that will pull all of the available disks that we have on our system.
We're going to select the one that we just formatted. By the way, we're doing a clean install of the Server operating system. We would do this differently, obviously, if we were upgrading over a previous Server OS. If we were upgrading, we would have simply already had a Server OS on this disk, and this button instead of saying Install would have said Upgrade, and we could click that and do that. But we are doing a full installation, and we're going to stick with the defaults. We could click Customize here and we could remove some of the default installations. But in fact, we're going to leave all of the stuff on and in fact, we're going to turn on QuickTime 7 for compatibility purposes as well.
I'm going to leave all of that on. If you want to save space, you can save this 223.3 MB by turning off the Language Translations. I'll flip this down and show you what this is. This is just different language translations for the UI of the server. If you need to be more efficient with your disk space, you can save a lot of space by simply removing printer support, as printers are frequently not used on servers. Click OK and we'll click Install. When we click Install, this is our last opportunity to do anything with our installer here.
So we're going to click here. This process will take between 15 and 30 minutes, depending upon the media that you're installing from. When it's finished, it will do an automatic restart, leaving you at the Server Setup Assistant.
