Build
We're now going to discuss how to build the strfry29 plugin.
Dependencies
Before building the binary, we need to install the dependencies.
strfry
Since strfry29 is a plugin for strfry, you need to first make sure you have properly installed and configured strfry before continuing.
You can follow along with the strfry guide to install and configure strfry.
Go
After setting up strfry, we need to now install Go. The strfry29 plugin we're using is written in Go, so we need to install Go to be able to build the binary.
First, you need to determine which version of Go you want to install which you can do by going to the All releases page on the Go website.
Make sure to choose the appropriate download file for your relay's operating system (OS) and architecture. Since we're using Debian with an AMD processor, we're going to download the linux-amd64 file.
At the time of writing the current version of Go is 1.23.2, so we'll be downloading the go1.23.2.linux-amd64.tar.gz file.
We'll be downloading the file to the /tmp directory which is cleared when the system reboots. We’ll be downloading the file here because we won’t need this file after the installation process is completed.
Since we're using a headless server, we can use the wget command to download Go:
Be sure to replace go1.23.2.linux-amd64.tar.gz with whatever version of Go you're downloading and with whatever architecture you're using.
Before extracting the contents of the file, be sure to first remove any previously installed version of Go:
You can now extract the contents of the file into the /usr/local directory:
Be sure to not extract the contents into an already existing /usr/local/go directory since this can break the Go installation.
After successfully extracting the contents, you should see a go directory in the /usr/local directory:
You can now add /usr/local/go/bin to the PATH environment variable by adding export PATH=$PATH:/usr/local/go/bin to your $HOME/.bashrc file.
First open the file with a text editor of your choice, e.g., nano:
Then add the following to the end of the file:
Save the changes made to the .bashrc file and exit the editor.
The changes may not take effect until after you log back into the server.
To apply the changes immediately run:
Verify the installation was successful by running:
The command should output:
Clone the Repository
We're now ready to clone the relay29 repository.
We'll be downloading the repository to the $HOME directory.
Navigate to the $HOME directory:
We're now ready to clone the relay29 repository:
After cloning the repository, navigate to the relay29/strfry29 directory:
You can use the repository to update strfry29, so we're going to keep the repository on the relay.
Build strfry29
We're now ready to build the strfry29 example:
The compilation could take a while depending on your server's specs, so be patient while the binary is being built.
When the compilation is finished the binary will be located in the relay29/strfry29 directory.
You can list out the contents of that directory to see the binary:
You should see the binary file which should be named strfry29.
Version
At the time of writing, the latest version of the relay29 library is v0.4.0 which is what the rest of the guide is currently based on.
Run Binary
Before we can run the strfry binary which uses the strfry config file, the strfry29 binary, and the strfry29.json file located in the $HOME/relay29/strfry29 directory, we need to first create the strfry data directory specified in the strfry config file, i.e., strfry-db.
To create the strfry data directory run:
You can now run the binary:
strfry should now be listening on 127.0.0.1:52929 and by default only accepts connections from localhost.
To stop the relay press Ctrl+C.
