Sky's 'Quick and Clean' (as opposed to 'Dirty') How-To Series: Running an Epic Node on Linux If you are running the TUI option, you can't set up and run the node as a service since you can't get back to the TUI screen. You must run in a screen (sudo apt install screen). Then create an executable (chmod +x startnode) script file with this: #! /bin/sh sudo killall epic-node sleep 10 screen -S node-server -X quit screen -dmS node-server /home/pi/epic-node #end startnode If you want to restart the node every other day, create a cron job with: 17 2 */2 * * /home/pi/startnode Any time you want to check the node just run 'screen -r node-server' then when finished looking detach with <ctrl>a then d. Note: replace 'pi' with your username or the user you want to run the node under. Also rename server binary from epic to epic-node. If you aren't running TUI and you just check the log files, then you can set up the node to run as a system service. Create an epicnode.service file with this (and follow the install instructions in first 4 lines): # # To install: # sudo cp epicbox.service /etc/systemd/system/epicnode.service # sudo systemctl daemon-reload # sudo systemctl start epicnode.service # sudo systemctl enable epicnode.service # [Unit] Description=Epic Node Server service After=network.target [Service] ExecStart=/home/epicbox/startnode WorkingDirectory=/home/epicbox Restart=always StandardOutput=journal StandardError=journal SyslogIdentifier=epicbox User=epicbox Group=epicbox Environment=RUST_LOG=info [Install] WantedBy=multi-user.target #end service file Note: replace 'epicbox' with your username or the user you want to run the node under. You can set up a cron job just like for screen except the command would be 'sudo systemctl restart epicnode' instead of 'startnode' You can monitor the stdout output with 'journalctl -fu epicnode.service' For about $60 you can get a Libre 'Le Potato' SBC similar to a Raspberry Pi4 with WiFi, power supply and acrylic case and run Raspbian OS Lite headless by connecting via SSH and run your own external node server while taking up the space of a deck of cards.

Synapse Labs fundamentally believes in the power of Open Source development, and scaling Ethereum through L2s like optimism. Additionally, to date 90% of all dev costs have been paid by open source DAOs. Go check out our proposal here:
