How to install and run a node on Linux
A linux node can be installed and setup on a personal linux machine, in home server, or in a datacenter.
Here is the list of system requirements that should be fulfilled to be able to install Mysterium Node.
- CPU: 1 core
- RAM: 1GB
- DISK: 500MB free disk space
As an example, a raspberry PI 3 or a VPS with 1core CPU and 1GB RAM is enough to run a node.
- Raspbian 9/10
- Debian 9/10
- Ubuntu 18.04/20.04
Other debian based linux distributions should also be able to run node without any issues.
In order to complete this setup, you should have a non-root user with
There are 2 ways to install a stable release of Mysterium node:
Ubuntu systems you can use
Aptitude and execute:
sudo add-apt-repository ppa:mysteriumnetwork/node sudo apt-get update sudo apt install myst
We also provide an installation script written in
bash which can be downloaded and executed using this command:
sudo apt-get install curl sudo -E bash -c "$(curl -s https://raw.githubusercontent.com/mysteriumnetwork/node/master/install.sh)"
In addition to downloading and installing our Node, these commands will also install additional required dependencies like WireGuard and OpenVPN if you don't have them already.
Once the installation is complete, check your service status.
Latest non stable releases include bug fixes and improvements that have not yet been pushed
for the whole user base and are not guaranteed to work. You should run these releases at your own risk
and should also consider backing up your
.mysterium folder beforehand just in case.
Once the service is installed and running to finish the node installation continue to the nodeUI, where you'll be able to configure prices, extra service settings and check node stats and connections. Instructions on how to find and use it can be found: here.
Also make sure to claim your node in MMN to receive bounties. It can be found here. To receive your key, you'll have to create an account when following the nodeUI onboarding process or add it later in the node settings.
If you can't access nodeUI or service is not working as expected, follow the below instructions on how to check service health, diagnose issues or add extra configuration.
Post installation service check:
sudo systemctl status mysterium-node.service
If everything is working you should see similar output to this:
mysterium@pop-os:~$ sudo systemctl status mysterium-node.service ● mysterium-node.service - Server for Mysterium - decentralised VPN Network Loaded: loaded (/lib/systemd/system/mysterium-node.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2021-01-04 00:00:00 GMT; Docs: https://mysterium.network/ Main PID: 1920 (myst) Tasks: 30 (limit: 19009) Memory: 73.0M
Run the following command to diagnose issues:
sudo journalctl -u mysterium-node.service
To view the real-time daemon logs:
sudo journalctl -fu mysterium-node.service
If your node is unable to report an issue through the built-in Node UI or TequilAPI, you may need to save the logs to a file and send them to us via firstname.lastname@example.org.
sudo journalctl -u mysterium-node.service > node.logs
When your node is running you can print the config that it has currently loaded by executing:
myst config show
This config can be altered in several ways, which we'll cover below.
On initial start up node will create a config file which can be editted.
The config is located in:
Any text editor can be used to edit this file. As it's a
.toml file formatting and
indentation is very important. For further reading follow the official toml guide.
Editing start up options instead of the
config.toml file has one crutial benefit: start up service options
overwrite any default or
config.toml edited config values and become a single source of truth which cannot be changed at runtime.
Node typically runs as a systemd service, you can find the
.service file by inspecting the service, which you can do
systemctl status mysterium-node.service | grep Loaded
The output of this command will be something similar to:
Loaded: loaded (/lib/systemd/system/mysterium-node.service; enabled; vendor preset: enabled)
The file location we can see in parentheses is our
.service file location.
If you now inspect that file using
cat /lib/systemd/system/mysterium-node.service you will find a line
similar to this:
ExecStart=/usr/bin/myst $CONF_DIR $SCRIPT_DIR $DATA_DIR $RUN_DIR $DAEMON_OPTS service --agreed-terms-and-conditions $SERVICE_OPTS
This is the line that gets executed when we start up the
Node service. Here we're mainly interested in variables that are passed
to this command (variables are the strings which start with $ sign for example
$CONF_DIR). These variables are defined in a file which is located at:
To edit the node configuration and launch options we want to edit the variable
$SERVICE_OPTS adding additional flags to it, which will get passed
node once it's started. For example if we wanted to change our
wireguard default ports we would replace it with this:
SERVICE_OPTS="--openvpn.port 4443 --wireguard.listen.ports 52820:53075 openvpn,wireguard"
$SERVICE_OPTS variable should always finish with
openvpn,wireguard so any configuration you want to add, must go before that.
To get the full list of configuration options execute:
In most cases a simple service reload should be enough. You can do that by running:
sudo systemctl restart mysterium-node.service
After running the
restart command make sure to check the service health and currently running config
using previously mentioned commands.
If node is refusing to restart and load the changes you've made, you can try to restart systemd daemon itself by running
Add node-dev repository:
sudo add-apt-repository ppa:mysteriumnetwork/node-dev sudo apt-get update sudo apt-cache policy myst
You'll see similar output to the following:
root@server:~# apt-cache policy myst myst: Installed: 0.42.2+build254103644+focal Candidate: 0.42.1+1snapshot+20210209T0736+c7e732d6+build253474985+focal Version table: 0.42.2+build254103644+focal 500 500 http://ppa.launchpad.net/mysteriumnetwork/node/ubuntu focal/main amd64 Packages *** 0.42.1+1snapshot+20210209T0736+c7e732d6+build253474985+focal 500 500 http://ppa.launchpad.net/mysteriumnetwork/node-dev/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status
Look for the version that has snapshot in its name such as:
Copy that name and run:
sudo apt install myst=<snapshot_name>
Your node should be running the snapshot version.
To return to a stable version, run:
sudo apt install myst
