Install Ubuntu 22.04
- Install Ubuntu 22.04 Server on all nodes with most default values.
- Create a non-root user (e.g., admin) during setup.
Login Using the Admin User
- Login to each node using the admin user.
Configure History Retention
- Enable storing date and time along with each command in history, as explained in the guide:
Storing date / time along with commands in history
Install Essential Packages
sudo su - apt update apt -y install openssh-server vim htop stress munge
Set Root Password
passwd
Enable Root SSH Access
- Edit the SSH configuration file:
vim /etc/ssh/sshd_config
- Locate and change the following line:
PermitRootLogin yes
Restart SSH Service
systemctl restart sshd
Stop and disable OS firewall services
systemctl stop ufw systemctl disable ufw
Add IP Address and Hostname Mapping
On all nodes, including containers and VM/bare-metal systems, add the IP address and hostname mapping entries into the `/etc/hosts` file.
Also, make sure to comment out the default hostname entry like this:
#127.0.1.1 <hostname>
Example
#127.0.1.1 infra 192.168.2.5 infra.local infra 192.168.2.3 node2.local node2 192.168.2.4 node1.local node1 192.168.2.6 slurm-login.local slurm-login 192.168.2.7 slurm-db.local slurm-dbsrv 192.168.2.8 slurm-master.local slurm-master 192.168.2.9 slurm-ldap.local slurm-ldapsrv
Install Environment Modules
apt install -y environment-modules
Re-login for Modules to Work
- After installation, logout and login again into each node to ensure module command works.
Configure Module Path
- Edit the module path configuration file:
vim /etc/environment-modules/modulespath
- Add the following line:
/export/modules
