Run Avalanche Node in Background

This page demonstrates how to set up a avalanchego.service file to enable a manually deployed validator node to run in the background of a server instead of in the terminal directly.

Make sure that AvalancheGo is already installed on your machine.

Steps​

Fuji Testnet Config​

Run this command in your terminal to create the avalanchego.service file

sudo nano /etc/systemd/system/avalanchego.service

Paste the following configuration into the avalanchego.service file

Remember to modify the values of:

  • user=
  • group=
  • WorkingDirectory=
  • ExecStart=

For those that you have configured on your Server:

[Unit]
Description=Avalanche Node service
After=network.target
 
[Service]
User='YourUserHere'
Group='YourUserHere'
Restart=always
PrivateTmp=true
TimeoutStopSec=60s
TimeoutStartSec=10s
StartLimitInterval=120s
StartLimitBurst=5
WorkingDirectory=/Your/Path/To/avalanchego
ExecStart=/Your/Path/To/avalanchego/./avalanchego \  
   --network-id=fuji \
   --api-metrics-enabled=true 
 
[Install]
WantedBy=multi-user.target

Press Ctrl + X then Y then Enter to save and exit.

Now, run:

sudo systemctl daemon-reload

Mainnet Config​

Run this command in your terminal to create the avalanchego.service file

sudo nano /etc/systemd/system/avalanchego.service

Paste the following configuration into the avalanchego.service file

[Unit]
Description=Avalanche Node service
After=network.target
 
[Service]
User='YourUserHere'
Group='YourUserHere'
Restart=always
PrivateTmp=true
TimeoutStopSec=60s
TimeoutStartSec=10s
StartLimitInterval=120s
StartLimitBurst=5
WorkingDirectory=/Your/Path/To/avalanchego
ExecStart=/Your/Path/To/avalanchego/./avalanchego \
   --api-metrics-enabled=true
 
[Install]
WantedBy=multi-user.target

Press Ctrl + X then Y then Enter to save and exit.

Now, run:

sudo systemctl daemon-reload

Start the Node​

This command makes your node start automatically in case of a reboot, run it:

sudo systemctl enable avalanchego

To start the node, run:

sudo systemctl start avalanchego
sudo systemctl status avalanchego

Output:

socopower@avalanche-node-01:~$ sudo systemctl status avalanchego

To see the synchronization process, you can run the following command:

sudo journalctl -fu avalanchego
