Camino Node Install Script
We have a shell (bash) script that installs Camino-Node on your computer. This script sets up full, running node in a matter of minutes with minimal user input required.
Before you start
Camino is a lightweight protocol which let nodes run on commodity hardware. Note that as network usage increases, hardware requirements may change.
- CPU: Equivalent of 8 AWS vCPU
- RAM: 16 GiB
- Storage: 512 GiB
- OS: Ubuntu 18.04/20.04 or MacOS >= Catalina
This install script assumes:
- Camino-Node is not running and not already installed as a service
- User running the script has superuser privileges (can run
If you run a different flavor of Linux, the script might not work as intended. It assumes
systemd is used to run system services. Other Linux flavors might use something else, or might have files in different places than is assumed by the script.
If you have a node already running on the computer, stop it before running the script.
Node running from terminal
If your node is running in a terminal stop it by pressing
Node running as a service
If your node is already running as a service, then you probably don't need this script. You're good to go.
Node running in the background
If your node is running in the background (by running with
nohup, for example) then find the process running the node by running
ps aux | grep camino-node. This will produce output like:
ubuntu 6834 0.0 0.0 2828 676 pts/1 S+ 19:54 0:00 grep camino-node
ubuntu 2630 26.1 9.4 2459236 753316 ? Sl Dec02 1220:52 /home/ubuntu/build/camino-node
Look for line that doesn't have
grep on it. In this example, that is the second line. It shows information about your node. Note the process id, in this case,
2630. Stop the node by running
kill -2 2630.
Node working files
If you previously ran an Camino-Node node on this computer, you will have local node files stored in
$HOME/.caminogo directory. Those files will not be disturbed, and node set up by the script will continue operation with the same identity and state it had before. That being said, for your node's security, back up
staker.key files, found in
$HOME/.caminogo/staking and store them somewhere secure. You can use those files to recreate your node on a different computer if you ever need to.
To run successfully, Camino-Node needs to accept connections from the Internet on the network port
9651. Before you proceed with the installation, you need to determine the networking environment your node will run in.
Running on a cloud provider
If your node is running on a cloud provider computer instance, it will have a static IP. Find out what that static IP is, or set it up if you didn't already. The script will try to find out the IP by itself, but that might not work in all environments, so you will need to check the IP or enter it yourself.
Running on a home connection
If you're running a node on a computer that is on a residential internet connection, you have a dynamic IP; that is, your IP will change periodically. The install script will configure the node appropriately for that situation. But, for a home connection, you will need to set up inbound port forwarding of port
9651 from the internet to the computer the node is installed on.
As there are too many models and router configurations, we cannot provide instructions on what exactly to do, but there are online guides to be found (like this, or this ), and your service provider support might help too.
Running the script
So, now that you prepared your system and have the info ready, let's get to it.
To download and run the script, enter the following in the terminal:
wget -nd -m https://raw.githubusercontent.com/chain4travel/camino-docs/main/scripts/camino-node-installer.sh;\
chmod 755 camino-node-installer.sh;\
And we're off! The output should look something like this:
Found arm64 architecture...
Looking for the latest arm64 build...
Will attempt to download:
camino-node-linux-arm64-v0.1.0.tar.gz 100%[=========================================================================>] 29.83M 75.8MB/s in 0.4s
Unpacking node files...
Node files unpacked into /home/ubuntu/camino-node
And then the script will prompt you for information about the network environment:
To complete the setup some networking information is needed.
Where is the node installed:
1) residential network (dynamic IP)
2) cloud provider (static IP)
Enter your connection type [1,2]:
1 if you have dynamic IP, and
2 if you have a static IP. If you are on a static IP, it will try to auto-detect the IP and ask for confirmation.
Detected '220.127.116.11' as your public IP. Is this correct? [y,n]:
n if the detected IP is wrong (or empty), and then enter the correct IP at the next prompt.
The script will then continue with system service creation and finish with starting the service.
Installing service with public IP: 18.104.22.168
Created symlink /etc/systemd/system/multi-user.target.wants/camino-node.service → /etc/systemd/system/camino-node.service.
Your node should now be bootstrapping on the main net.
Node configuration file is /home/ubuntu/.caminogo/configs/node.json
To check that the service is running use the following command (q to exit):
sudo systemctl status camino-node
To follow the log use (ctrl+C to stop):
sudo journalctl -u camino-node -f
Reach us over on https://discord.gg/K5THjAweFB if you're having problems.
The script is finished, and you should see the system prompt again.
Camino-Node should be running in the background as a service. You can check that it's running with:
sudo systemctl status camino-node
This will print the node's latest logs, which should look like this:

active (running) which indicates the service is running ok. You may need to press
q to return to the command prompt.
To find out your NodeID, which is used to identify your node to the network, run the following command:
sudo journalctl -u camino-node | grep "NodeID"
It will produce output like:
Jan 05 10:38:38 ip-11-11-11-11 caminogo: INFO [01-05|10:38:38] caminogo/node/node.go#428: Set node's ID to 6seStrauyCnVV7NEVwRbfaT9B6EnXEzfY
NodeID- to the value to get, for example,
NodeID-6seStrauyCnVV7NEVwRbfaT9B6EnXEzfY. Store that; it will be needed for staking or looking up your node.
Your node should be in the process of bootstrapping now. You can monitor the progress by issuing the following command:
sudo journalctl -u camino-node -f
ctrl+C when you wish to stop reading node output.
Stopping the node
To stop Camino-Node, run:
sudo systemctl stop camino-node
To start it again, run:
sudo systemctl start camino-node
Camino-Node is an ongoing project and there are regular version upgrades. Most upgrades are recommended but not required. Advance notice will be given for upgrades that are not backwards compatible. When a new version of the node is released, you will notice log lines like:
Jan 08 10:26:45 ip-172-31-16-229 caminogo: INFO [01-08|10:26:45] caminogo/network/peer.go#526: beacon 9CkG9MBNavnw7EVSRsuFr7ws9gascDQy3 attempting to connect with newer version camino/0.1.0. You may want to update your client
It is recommended to always upgrade to the latest version, because new versions bring bug fixes, new features and upgrades.
To upgrade your node, just run the installer script again:
It will detect that you already have Camino-Node installed:
Found 64bit Intel/AMD architecture...
Found Camino-Node systemd service already installed, switching to upgrade mode.
It will then upgrade your node to the latest version, and after it's done, start the node back up, and print out the information about the latest version:
Node upgraded, starting service...
New node version:
camino/0.1.0 [network=camino, database=v1.0.0, commit=f76f1fd5f99736cf468413bbac158d6626f712d2]
File that configures node operation is
~/.caminogo/configs/node.json. You can edit it to add or change configuration options. The documentation of configuration options can be found here. Default configuration may look like this:
Note that configuration file needs to be a properly formatted
JSON file, so switches are formatted differently than for command line, so don't enter options like
--dynamic-public-ip=opendns but as in the example above.
Using a previous version
The installer script can also be used to install a version of Camino-Node other than the latest version.
To see a list of available versions for installation, run:
It will print out a list, something like:
To install a specific version, run the script with
--version followed by the tag of the version. For example:
./camino-node-installer.sh --version v0.1.0
Note that not all Camino-Node versions are compatible. You should generally run the latest version. Running a version other than latest may lead to your node not working properly and, for validators, not receiving a staking reward.
Reinstall and script update
Installer script gets updated from time to time, with new features and capabilities added. To take advantage of new features or to recover from modifications that made the node fail, you may want to reinstall the node. To do that, fetch the latest version of the script from the web with:
wget -nd -m https://raw.githubusercontent.com/chain4travel/camino-docs/main/scripts/camino-node-installer.sh
After the script has updated, run it again with the
--reinstall config flag:
This will delete the existing service file, and run the installer from scratch, like it was started for the first time. Note that the database and NodeID will be left intact.
If you're on a residential network (dynamic IP), don't forget to set up port forwarding. If you're on a cloud service provider, you're good to go.
Now you can interact with your node.
Finally, if you haven't already, it is a good idea to back up important files in case you ever need to restore your node to a different machine.
