Installing Debian
Come with a bootable USB stick with Debian Squeeze installed (as of 2010-05-25, all physical servers are being installed with squeeze and will be creating KVM virtual servers).
Note - to get newer Dell machines to install that have the non-free Broadcom network drivers, mount the USB installer at /mnt and then run:
aptitude download firmware-bnx2 firmware-linux firmware-linux-nonfree cp firmware* /mnt/
Initial steps
- Plug in monitor and keyboard
- Boot machine while USB stick is inserted
- Enter Bios/Setup. Specify that Bios should output to serial console and make our standard bios changes
- Ensure that server skips errors like no keyboard attached
- Reboot and select Boot Options and choose to boot to USB stick
- Choose Expert install
- For DNS servers, use:
Telehouse: 209.51.163.29 209.51.169.83 XO: 209.234.253.168
- When prompted for component to use, include all of them to be safe (but be sure to include the SSH server one)
- When given the option - choose to continue your installation via ssh - this will give you the ability to easily set and record pass phrases
- Drive partioning. If you are using 2TB disks or greater... Open a new ssh session and choose to switch to console.
parted /dev/sda mklabel gpt parted /dev/sdb mklabel gpt parted /dev/sda unit s mkpart biosboot 2048 4095 parted /dev/sda set 1 bios_grub on parted /dev/sdb unit s mkpart biosboot 2048 4095 parted /dev/sdb set 1 bios_grub on parted /dev/sda unit s mkpart boot 4096 1052671 parted /dev/sda set 2 raid on parted /dev/sdb unit s mkpart boot 4096 1052671 parted /dev/sdb set 2 raid on parted /dev/sda unit s mkpart pv 1052672 3905974271 parted /dev/sda set 3 raid on parted /dev/sdb unit s mkpart pv 1052672 3905974271 parted /dev/sdb set 3 raid on
When done, type:
parted /dev/sda unit s p parted /dev/sdb unit s p
And you should get:
~ # parted /dev/sda unit s p Model: ATA WDC WD20EADS-00R (scsi) Disk /dev/sda: 3907029168s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 4095s 2048s biosboot bios_grub 2 4096s 1052671s 1048576s boot raid 3 1052672s 3905974271s 3904921600s pv raid ~ # parted /dev/sdb unit s p Model: ATA ST32000542AS (scsi) Disk /dev/sdb: 3907029168s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 4095s 2048s biosboot bios_grub 2 4096s 1052671s 1048576s boot raid 3 1052672s 3905974271s 3904921600s pv raid ~ #
You should be able to return to the graphical installer to do the rest.
For the record - here's how you can do it by hand:
RAID:
mdadm --create --raid-devices=2 --level=1 --metadata=1.0 --verbose /dev/md0 /dev/sda2 /dev/sdb2 mdadm --create --raid-devices=2 --level=1 --metadata=1.0 --verbose /dev/md1 /dev/sda3 /dev/sdb3
Now cryptsetup:
anna-install cryptsetup-udeb cryptsetup luksFormat /dev/md1 cryptsetup luksOpen /dev/md1 md1_crypt pvcreate /dev/mapper/md1_crypt vgcreate --name vg_nameofserver0 /dev/mapper/md1_crypt lvcreate --name swap --size 1GB vg_nameofserver0 etc.
Choose manual partition in the Debian Installer. Then:
- Choose "Congifure software RAID" (skip step if one disk system)
- Choose "Create MD Device"
- Choose RAID1
- Number of active devices: 2
- Number of spare devices: 0
- Now select the second partition on each device.
- Click Continue. Repeat for third partition on each device.
- When you are done, click Finish. Now you are back at the partition menu.
- Scroll down to the raid devices (or apply straight to your partitions if it's a one disk system). Modify the 512 MB RAID device: Filesystem: ext3, mount on /boot
- Encrypt the larger, remaining device. Give password to Jamie.
- Choose "Congifure LVM" (selecting the device encrypted in the previous step)
- Create a volume group called
vg_
nameofserver0
- Create logical volumes in this volume group based on your needs. Suggestions: 3GB for /, 1GB swap.
- After returning to the main disk config menu, click on each logical volume that you create and specify how it should be formatted and mounted.
- Enter root password. Give to Jamie.
- Create a second user for yourself.
- Do not install the server package or the base package - deselect all of them.
