Sample deployment of a new server

In this section we describe the deployment of a new server from scratch. All the operations will be performed using bob, the command-line client for interacting with sysdb.

The informations we need are:

• the server name: logging-ra.psi.ch
• the server MAC address: 23:3d:ef:33:11:22
• static or dynamic IP: static
• the OS installer: rhel79server
• the server role: role::logging_server
• the server environment in puppet: prod
• the sysdb environment: daas
• optional the group inside the sysdb environment (default if not specified): logging

Setting up bob

The bob tool is already set up on lxsup00.psi.ch. You might connect with ssh and use it from there.

Altenatively you many have on your workstation a local copy of bob. This can be done by installing the RPM from the pli-misc repository - https://repo00.psi.ch/el7/manual/pli-misc/

You might need to set a PSI_BOB_USER environment variable (export PSI_BOB_USER=<you-name-it>) or use the option --user if your local user is different from the one on sysdb.

Sysdb configuration

We then create a deployment environment:

bob env add daas talamo_i daas-admins 'DaaS Cluster'

We add the node to the environment, specifing netboot as the boot action :

bob node add logging-ra.psi.ch daas netboot

We setup its MAC address: :

bob node add-mac logging-ra.psi.ch 23:3d:ef:33:11:22

Next decide how the IP address is configured (dhcp or static): :

bob node set-attr syslog-ra.psi.ch network=static

And which installer is used: :

bob node set-attr syslog-ra.psi.ch ipxe_installer=rhel79server

And we finally setup the puppet role and puppet environment: :

bob node set-attr syslog-ra.psi.ch puppet_role=role::log_server
bob node set-attr syslog-ra.psi.ch puppet_env=prod
bob node set-attr syslog-ra.psi.ch puppet_group=logging

Example

Full example:

bob node add lx-test-02.psi.ch pli netboot bob node add-mac lx-test-02 00:50:56:9d:19:76 bob node set-attr lx-test-02.psi.ch ipxe_installer=rhel87install bob node set-attr lx-test-02.psi.ch puppet_env=prod bob node set-attr lx-test-02.psi.ch puppet_group=default bob node set-attr lx-test-02.psi.ch puppet_role=role::server bob node netboot lx-test-02.psi.ch bob node list -v lx-test-02

Ensure that a potential previous puppet certificate for this server is deleted on the puppet server: https://puppet.psi.ch

PXE server-side configuration

In case the node is configured to use legacy BIOS mode (and not UEFI mode) the following has to be run on the PXE server to make the node boot the ipxe image: :

cd /afs/psi.ch/service/linux/tftpboot/pxelinux.cfg/
ln -sf lxprod logging-ra
MAC='the::node::mac::address'
MACFILENAME="01-`echo $MAC|tr 'A-Z' 'a-z'| sed 's/:/-/g'`"
ln -sf logging-ra $MACFILENAME

Otherwise the node will boot with the old pxe configuration. In such case is possible to boot ipxe typing lxprod on the PXE command line.
