Introduction
Here are the instructions on how to build Cluster 7 using Ubuntu 20.04.
The build is not complete as of October 19, 2021.
Hardware Requirements (so far)
- 2 x 1 gigabit unmanaged switches
- one switch for private IP
- one switch for public IP
- 4 x unused ProLiant DL160 G5 Machines
- one for NAT machine
- one for Foreman Server
- one for LDAP Server
- one extra for any testing
- 1 x USB for Operating System (OS)
Create a Network Address Translation(NAT) machine
A NAT machine will act as a local VPN to the cluster. This will be the first machine you SSH into.
Current machine:
- Hostname: segundo.dot
- IP Address: 10.70.1.2
Instructions
- Install Ubuntu 20.04 using USB. You can set everything to default but make sure to disable network interfaces if DHCP Server is not set up yet.
- After OS installation, grab MAC Address of network interface enp4s0. You'll need it to make a public IP.
- ip a
- Create a DNS entry for this machine in the website below to give you a public IP address
- File a ticket to UCSF IT to open port 22 for the NAT machine
- Configure private and public network interfaces
- vim /etc/netplan/00-installer-config.yaml
- Configuration should look like this:
- # This is the network config written by 'subiquity'
- network:
- ethernets:
- enp3s0:
- addresses:
- - 10.70.1.2/16
- gateway4: 127.0.0.1
- nameservers:
- addresses:
- - 10.70.1.1
- search:
- - dot
- enp4s0:
- addresses:
- - 169.230.26.58/16
- gateway4: 169.230.26.1
- nameservers:
- addresses:
- - 8.8.8.8
- - 8.8.4.4
- - 128.218.254.10
- - 128.218.254.40
- search:
- - dot
- - compbio.ucsf.edu
- version: 2
- ethernets:
- Test if configuration works by pinging google
- ping google.com
