Installing onto Ubuntu Server environments apart from DigitalOcean

The following notes may be helpful if choosing to install on unsupported environments running Ubuntu Server 20.04 LTS.

Lamassu can only provide technical support for installation on DigitalOcean due to the variables involved in custom server environments.

Run:

sudo -i
apt update && apt upgrade -y

Run ifconfig to find the adapter MAC address for the adapter you're going to use. E.g. you might see HWaddr 50:9a:4c:1d:19:14, the 50:9a:4c:1d:19:14 of whatever your system says is your ADAPTER MAC which you have to specify in the next step.

Edit /etc/udev/rules.d/70-persistent-net.rules to specify ATTR{address}=="ADAPTER MAC" in the following line:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="ADAPTER MAC", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"

Edit /etc/network/interfaces to point the non-lo interface to eth0 instead of ens3 or similar.

Run:

shutdown -r now

Upon logging back in, run:

sudo -i
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
apt update
apt install -y git ufw nodejs python-minimal build-essential supervisor postgresql libpq-dev
npm config set prefix '/usr'
echo -e "export PATH=/usr/bin:/usr/lib/node_modules/lamassu-server/bin:\$PATH" >> ~/.profile
source ~/.profile

Then download the install script:

wget https://raw.githubusercontent.com/lamassu/lamassu-install/electric-enlil/install

Edit the install script, inserting swapoff -a between these two lines:

decho "Enabling swap file for install only..."
swapoff -a
fallocate -l 1G /swapfile >> $LOG_FILE 2>&1

Then change all npm calls in the install file to sudo npm

Run:

bash install
