Below are instructions for adding a machine to the CS or Cluster network.

Note that if you're ever confused, you can look at another machine and do some "comparative anatomy" to see how certain files should be edited.

Install a base OS

Generally, CS machines run Debian and cluster machines run CentOS.

Bring up at least one network interface

Depending on the OS you install, there's a strong possibility the network interface won't be brought up by default.

Configure DNS and DHCP

See this page for how to configure the DNS and DHCP server to recognize the machine.

Locally, you'll need to edit /etc/resolv.conf (to, e.g., specify your DNS nameserver), the config file for your particular network interface (e.g. on CentOS you may care about /etc/sysconfig/network-scripts/ifcfg-enp1s0f0), and /etc/hosts (to set your own hostname).

Configure LDAP

Most likely, new servers will be connected to our LDAP database for user account sharing purposes.

Install the base software kit

Go here for that.
