Step by step guide to setup a IPFS node

Nowadays IPFS node is important for running some blockchain applications and nodes. For example, SPKCC uses IPFS and it is important to have a local node running use the configuration if you SPKCC config files. I usually prefer running my nodes using pm2 instead of Docker. But both are good with their own advantages. In my case the nodes are pretty lightweight if I do it with pm2 and also version management is easier for me. So I prefer the non-docker method.

We are going to be installing kubo in this setup guide. The current version of kubo at the time of writing this article was v0.14.0 and before this version, it was called go-ipfs. I was using an older version on one of my servers and recently installed the new version on a different server. I wanted to write this step-by-step guide so that it is useful for me when I want to do it the next time. Of course, it is also helpful for people who are doing their first-time setup as well.

Step 1: Download and exact the setup file

There are two places to get the IPFS setup file.

https://dist.ipfs.tech/#kubo

The above gives us some details and links to other things if we want. We can download the tar file from there based on the version of our operating system.

Another alternative place is to check for the new releases of kubo from the GitHub releases page and pick the tar file from there. There will be multiple files available and good to pick the file based on our operating system.

https://github.com/ipfs/kubo/releases

Use the below command to download the setup file. I wanted these files to be inside a folder, so I created a new directory called ipfs and extracted the file there.

mkdir ipfs
wget https://github.com/ipfs/kubo/releases/download/v0.14.0/kubo_v0.14.0_linux-amd64.tar.gz
tar xvfz kubo_v0.14.0_linux-amd64.tar.gz

Step 2: Install IPFS

The next step is to navigate inside the folder and execute install.sh file.

cd kubo
sudo ./install.sh

After the installation is complete, the below output will be displayed in the logs.

Moved ./ipfs to /usr/local/bin

This doesn't mean that the IPFS node is running already.

Step 3: Initialize IPFS

The below command is for initializing IPFS.

ipfs init --profile server

The above command will initialize the IPFS node at ./root/.ipfs

Note: The server profile option is recommended for running in a data center. Using this profile will prevent IPFS from trying to discover local nodes, and reduce network traffic. Some hosting providers also have a policy against running IPFS, unless you use the server profile.

Step 4: Update the config file

The next step is the navigate to the initialized folder and update the config file.

cd ~\.ipfs
nano config

There are no big changes required if you would like to retain the default settings. If you would like to change some of the settings, updating the config file is important. There are two things that people usually change. The first is to update the maximum storage limit. By default, it is 10G and it can be changed to any value based on your need.

The second change is the port number. Again this is also not a mandatory step but I wanted to change it. In my case, I changed the port number of the API from default 5001 to 4002. You can change it to whatever you want.

Step 5: Start the Server

We have to run the server with the help of pm2. If you don't have pm2 installed, you have to first install nodejs and then install pm2. Assuming this should be a known step, I'm not going to cover that part in this tutorial. Use the below command to start the server:

pm2 start "ipfs daemon --enable-gc" --name ipfs --time

The above command will name the service as ipfs and also start the server with garbage collection enabled. If you want to restart the service if the memory consumption is high, you can include other criteria.

pm2 start "ipfs daemon --enable-gc" --name ipfs --time --max-memory-restart 3G

The above command will restart the node if the memory goes beyond 3G. You can customize it however you want.
After the service is started, you can view the logs with the below command:

pm2 logs ipfs

Based on the ports we changed, the API server is running in 4002.

The setup is complete and the IPFS can now be used in your apps. With this IPFS setup, my previous guide to set up the SPKCC node is now outdated. I will try to publish an updated guide including these steps.

Upgrading the node

The instructions are pretty much the same for upgrading the node as well.
