Setting up cosmovisor

// setup cosmovisor
go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@latest
// create 0G-labs cosmovisor folder
mkdir -p ~/.evmosd/cosmovisor/genesis/bin
mkdir -p ~/.evmosd/cosmovisor/upgrades
// copy the binary to cosmovisor
mv build/evmosd $HOME/.evmosd/cosmovisor/genesis/bin/

Setting up services

Now we’ll create a systemd service evmosd.service to control the node via cosmovisor. As root and with a text editor, open /etc/systemd/system/evmosd.service ( nano /etc/systemd/system/evmosd.service ) and type the following:

[Unit]
Description=evmosd node service
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) run start
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.evmosd"
Environment="DAEMON_NAME=evmosd"
Environment="UNSAFE_SKIP_BACKUP=true"
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:$HOME/.evmosd/cosmovisor/current/bin"

[Install]
WantedBy=multi-user.target

Start Services

// Enable
sudo systemctl enable evmosd
// Reload
sudo systemctl daemon-reload
// Start
sudo systemctl start evmosd


// Stop (if there is any problem)
sudo systemctl stop evmosd
// Restart
sudo systemctl restart evmosd

// Check Log
journalctl -fu evmosd

Make sure your nodes are already synced before creating your validator

use this command check your nodes status: evmosd status | jq
