Details on all the steps necessary to take a new (or old repurposed) piece of hardware and turn it into a happy functional server
Contents |
Before you begin
- find the machine's MAC address
- decide on private / public IP address, and if it will need to exist in some special range
- decide how the disks should be arranged (raid, partitioning, etc.)
Initial hardware setup
- Get the hardware racked and cabled (RobH)
- Get an IP and name (RobH)
- follow DNS How-To section to add the name/ip to DNS
- set up $name.mgmt.$loc.wmnet as well to access the management interface
- Set up DHCP with the MAC address / name info
- log into brewster and edit
/etc/dhcp3/*, run/etc/init.d/dhcpd3-server restart
- log into brewster and edit
- Get the switch set up to pass traffic to the host (Mark)
PXE boot and the initial OS
- set up netboot to partition the disk
- log into brewster, edit /srv/autoinstall/netboot.cfg
- it's a bash case statement. Add a new stanza for your hosts' name
- If you don't know what file to use and your host has two disks, use raid1-lvm.cfg.
- ssh to root@$servername.mgmt.$loc.wmnet, force a restart and pxe boot
- get the password from someone in ops if you don't have it
- powercycle the host:
racadm serveraction powercycle - connect to the cosole:
console com2 - during boot, force netboot:
escape-shift-2(sends F12) - you can leave this running to watch it complete
- Note: if you see it ask you for disk partitioning information, you did the partitioning step above wrong
- when you're done,
ctrl-\will disconnect you from the console
Get puppet running
- get a shell on both $server and the puppet master (sockpuppet)
- Only one key has access to new installs.
- from sockpuppet,
ssh -i ~/.ssh/new_install root@$servernameto log into $server
- on $server, run
puppetd --testIt will fail. - on sockpuppet, run
puppetca -s $server-fqdn - on $server, run
puppetd --testIt should now succeed.
Set up puppet
- add $server to site.pp, either by hostname or within a regex if it's part of a class (eg srv\d\d*)
- do whatever puppet goodies you want to get the server to do what you want it to.
