Systems - Media Server - Install Ubuntu Server
It is recommended to install a Long-Term Support (LTS) release of Ubuntu.
Steps
- Download the ISO image for Ubuntu Server from the Ubuntu website.
- Write the ISO image for Ubuntu Server to a USB drive.
- Boot from USB drive.
- Select Ubuntu Server and Search for third-party drivers.
- Set a static IP.
- Guided Storage Configuration - Select to Use the entire disk, and unselect “Set up this disk as an LVM group”.
- SSH Config - Select to Install OpenSSH Server.
- Reboot.
- Update.
- Clean up.
- Reboot again.
ALERT: To prevent accidentally installing Ubuntu on the wrong drive and overwriting data it is recommended to disconnect data drives during installation.
Set a static IP
Subnet: 192.168.1.0/24 Address: 192.168.1.85 Gateway: 192.168.1.1 Name Servers: 192.168.1.1, 192.168.1.50 Search Domains: <blank>
Update
sudo apt update && sudo apt upgrade -y
Clean up
sudo apt autoremove sudo apt clean sudo reboot
NOTE: This removes any unnecessary packages and cleans up the apt cache.
Change the default shell to bash
By default, Ubuntu has Dash as the default shell.
- The reason that dash was set as the default is that dash provides faster boot times.
- It does not however have the full feature set offered by bash.
- On a modern server this speed difference in booting is negligible; and not too important as servers usually are not booted very often.
- Bash is preferred.
Check what /bin/sh links to
ls -al /bin/sh <code> returns: <code> lrwxrwxrwx 1 root root 4 Mar 31 2024 /bin/sh -> dash
NOTE: This shows that /bin/sh links to dash.
Link /bin/sh to bash
sudo ln -sf bash /bin/sh ---- ==== Recheck what /bin/sh links to ==== <code bash> ls -al /bin/sh <code> returns: <code> lrwxrwxrwx 1 root root 4 May 30 15:15 /bin/sh -> bash
NOTE: This shows that /bin/sh now links to bash.
- On older Ubuntu systems the following could be used, but this no longer works on new versions:
sudo dpkg-reconfigure dash
- When asked Install dash as /bin/sh? specify No.
Update inputrc
Update /etc/inputrc to support being able to use arrow keys for history searches.
Add the following lines to the bottom of the file.
- /etc/inputrc
... # Peter added these "\e0A": history-search-backward "\e0B": history-search-forward "\e0C": forward-char "\e0D": backward-char "\e[A": history-search-backward "\e[B": history-search-forward "\e[C": forward-char "\e[D": backward-char
NOTE: This allows one to type the first letter of a previous command, and then by using the arrow up key for example, will only show previous commands also starting with that letter.
Remove snap if installed
List all installed Snap packages
snap list
Remove all the Snap packages
sudo snap remove <package_name>
Purge snapd
sudo apt purge snapd
NOTE: Clean up any remaining directories.
