Installing Linux on the Virtual Machine6:27 with Jay McGavren
Next we need to create a new virtual machine to hold our new operating system, and then install Linux onto it. The process is similar to plugging installation media into an actual computer, but we'll do it all virtually.
Next we're going to need an OS to install on our virtual machine. 0:00 We've chosen a Ubuntu too because it's commonly used. 0:03 To download it, visit To Ubuntu.com and then click on the download link. 0:06 And choose a Ubuntu Server. 0:14 You'll have a choice between a couple different versions of Ubuntu, 0:18 we're going to want the LTS version, which stands for long term support. 0:21 Basically that means it's going to be a more stable version of Ubuntu. 0:26 It'll begin downloading an ISO file which is basically a virtual 0:31 CD-ROM image from which you can install Ubuntu. 0:35 When the download completes we'll be ready to create a new virtual machine, 0:39 in the VirtualBox application click the New icon. 0:43 Since will be using this virtual machine to simulate a server at our 0:47 hosting company I'm gonna name it hostcom. 0:50 For the type of operating system it's going to host I'm gonna select Linux. 0:56 And then Ubuntu (64-bit) as the default for the operating system version. 1:00 I'll click Continue. 1:05 Next VirtualBox needs to know how much of your host computer's 1:08 ram that should devote to running the virtual machine. 1:10 I'm just going to go with the default. 1:13 Then it needs to create a file to hold the virtual hard disk for 1:16 this virtual machine. 1:18 I'm just going to go with the default, Create a virtual hard disk now. 1:20 I'll use VirtualBox Disk Image, which is the default. 1:25 To save space I'm going to let it dynamically allocate room 1:29 within the virtual disk file. 1:32 By default the virtual hard disk file will have the same name as the virtual machine 1:35 you're creating so I'll leave it at the default hostcom, and 1:39 I'll set its virtual size to the default again 8.00 gigabytes. 1:43 Okay, our virtual machine is now ready to run. 1:50 I'm going to click the Start button the start to start it up. 1:52 Now if this were a real server that you were installing Ubuntu for, 1:57 you'd probably plug a CD-ROM into the CD-ROM drive and boot it up so 2:00 that it could install the Ubuntu from the CD-ROM. 2:04 We're going to do the equivalent to that here in VirtualBox. 2:07 So you remember earlier, 2:11 we downloaded that ISO file which contains the contents of the Ubuntu installer. 2:12 We're going to use that ISO file as a virtual CD-ROM drive. 2:17 So, I'm gonna find, That ISO file here on our disk. 2:20 And once that selected all click Start. 2:32 The virtual machine will boot and will immediately begin running the contents of 2:36 the virtual CD-ROM, and at this point it'll launch into the Ubuntu installer. 2:39 I'll mostly be choosing the defaults for all these install options. 2:46 I work in English so I'll select that as my language, 2:49 I'll select that I want to install the Ubuntu Server. 2:52 I'll select defaults for most of the location options. 2:58 Now Ubuntu wants to know a host name for this server. 3:14 It can be anything you want, but it should ideally be a single word all lowercase. 3:18 I'm going to name it hostcom, the same as our virtual machine. 3:22 Now it wants to create a user account so I'll enter my name here. 3:28 Obviously you should substitute your own name. 3:31 And then it wants a username, 3:34 again ideally this will be a single word all lowercase. 3:36 I'll just go with the default. 3:39 Then it'll ask me to create a password. 3:42 You can choose whether you want to encrypt your home directory or not, 3:49 I'm going to opt not to. 3:52 I'll stick with the defaults for the time zone. 3:56 And if this were an actual server we might care about how the hard disk is 4:04 partitioned. 4:07 But since it's a virtual machine, 4:08 I'm just going to go with the defaults for everything. 4:09 So I'll use the entire virtual disk. 4:12 This is a potentially destructive change, so by default no is highlighted. 4:15 I'm going to select Yes and hit Enter. 4:19 I'll use the default for the amount of space. 4:21 And again I'll select Yes and confirm that I want to write the changes to disk. 4:27 Computers on some networks have to go through an HTTP proxy to 4:41 access the Internet. 4:45 If your network has one, you probably already know about it. 4:46 I don't have one so I'm going to just hit Enter. 4:49 Next, you can choose whether you want to automatically apply security updates to 4:56 the system. 5:00 I'm just going to go with the default, no updates. 5:01 Then it'll ask which software packages you want to install. 5:03 I want full control over what gets installed, 5:08 I'll be installing additional stuff from the command line later. 5:10 So I'm just going to install the standard system utilities and 5:13 leave everything else uninstalled for now. 5:17 For systems that have multiple operating systems installed at the same time, 5:22 Windows installed alongside Linux for example, you would need the grub 5:26 bootloader to let you select between those operating systems. 5:29 We're not going to set this machine up this way but 5:33 there's no harm in having the grub bootloader so 5:35 I'm going to select the default to install the grub bootloader. 5:37 And finally the installer will notify you that the installation is complete. 5:43 It will warn you to remove the installation media but 5:47 since this is a virtual machine we don't have to worry about that. 5:51 So I'm just going to hit Enter to continue. 5:53 The virtual machine will shutdown and 6:00 it'll reboot into the Ubuntu operating system. 6:02 You'll be asked for a login, go ahead and 6:09 enter the all lowercase username that you selected during the install. 6:12 And type in the password you selected. 6:17 And there you are, you'll be out of prompts for your new operating system. 6:22
