The Ultimate Ubuntu Server Install 18.04LTS
Main Installation
The main installation is slightly different in 18.04LTS, insert the Ubuntu Server (LTS 18.04LTS Live) installation CD/USB/DVD and follow the onscreen instructions. You may need to make sure your USB key / USB slot supports EEFI boot, it seems there are some potential issues with non-eefi USB boots and a python error.
If you don’t understand the questions asked by the installer put the keyboard down and switch everything thing off and go back to being a user.
You will be asked to select.
Language Keyboard Type of Ubuntu Install - Choose "Install Ubuntu"
Network Configuration: Use the cursor keys to configure the network interface with a static IP address. (set the IPv6 option to Do Not Use)
Internet Proxy: Set to whatever you user (none if you don't user one)
Disk Partitioning
When prompted choose
Use An Entire Disk
This will configure the system disk, with automatic boot / root / swap partitions. You can specify extra disks later and mount them if needed. You can also enter manual mode and select other disks and choose your mount points.
If you want to be safe, disconnect all disks apart from where you want the install, (then add them later)
root@solaris:/opt/mediawiki# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 86.6M 1 loop /snap/core/4486 loop1 7:1 0 86.6M 1 loop /snap/core/4650 sda 8:0 0 465.8G 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi └─sda2 8:2 0 465.3G 0 part / sdb 8:16 0 5.5T 0 disk └─sdb1 8:17 0 5.5T 0 part /srv/data sdc 8:32 0 2.7T 0 disk └─sdc1 8:33 0 2.7T 0 part /srv/media sdd 8:48 0 931.5G 0 disk └─sdd1 8:49 0 931.5G 0 part /srv/backup sr0 11:0 1 1024M 0 rom
You can edit the disk partitions before submitting to add further disks at specific mount points. Mount points used were.. (which in this case were manually configured as I did not want to lose existing data)
/srv/media (using ext4) /srv/data (using ext4) /srv/backup (using ext4)
To improve SATA SSD performance, create /etc/udev/rules.d/60-ssd-scheduler.rules:
# Set deadline scheduler for non-rotating disks ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="deadline"
To preserve the life of SSDs by reducing swap file usage, add the following to /etc/sysctl.conf:
# Decrease swap usage vm.swappiness=10
User Config
When prompted create the system login user / password The server will install the basics, set up your user / timezone etc. Eventually you will be prompted to Reboot.
Reboot Now
Set up software repositories and update system
We need to add additional repositories so we can download all the nice pieces of software and grab all the security updates, we do this by editing the config file listing the repositories.
sudo nano /etc/apt/sources.list
Note: sudo elevates you to ROOT status, by typing sudo –s before you begin maintains your elevated status so you don’t have to keep typing sudo; nano is a simple text editor. Note that ‘#’ and ‘;’ indicates the line has been commented out.
Comment/Uncomment and repositories you wish to use.
Now we have to get Ubuntu to update its internal repository database
sudo apt update
Now we can do a full distribution upgrade which gets us all the latest patches and fixes.
sudo apt dist-upgrade
Say yes to accept the installation. The dist upgrade may take some time to install,
You probably then want to update any of the minor packages.
sudo apt upgrade
Answer yes to any of the upgrade questions. After it is probably wise to reboot and make sure everything is still good. Especially as you have probably got your self an updated linux kernel.
sudo reboot
SSH Server
Check that SSH server is working, (it is now installed and set to run by default in 18.04) Run a PuTTY session to the server and check connectivity.
Network Interface Configuration
Configure a network bridge to present a single interface to the world, this is handy for VMs / VPNs etc. as we only need to reference the bridge. (br0:) 18.04 uses netplan to configure its network configuration.
The following steps will set up a bridge with a static IP address.
apt update apt dist-upgrade apt install bridge-utils
To get us up to date and install the bridge utilities.
Change to the netplan directory.
cd /etc/netplan mv 50-cloud-init.yaml 50-cloud-init.ORIG nano 01-bridge.yaml
Content of the 01-bridge.yaml
network: version: 2 renderer: networkd ethernets: switchports: match: {name: "ethxxxx*"} bridges: br0: interfaces: [switchports] dhcp4: no addresses: [192.168.3.201/24] gateway4: 192.168.3.1 nameservers: addresses: [192.168.3.200] parameters: stp: false forward-delay: 0
Disable the cloud network configuration.
nano /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
Add this statement to the empty file.
network: {config: disabled}
Apply the changes
netplan --debug apply
Reboot and check the network configuration with
ifconfig
You should have an interface of br0: with the ip you specified.
