git clone https://github.com/Agoric/agoric-sdk
cd agoric-sdk
git checkout agoric-upgrade-14
yarn install && yarn build
(cd packages/cosmic-swingset && make)
agd version

5. Initialize your node.

curl https://main.agoric.net/network-config > chain.json
chainName=`jq -r .chainName < chain.json`
echo $chainName

agd init --chain-id $chainName <node_name>

6. Download genesis.

curl https://main.agoric.net/genesis.json > $HOME/.agoric/config/genesis.json

7. Add seeds and peers to config.toml.

peers=$(jq '.peers | join(",")' < chain.json)
seeds=$(jq '.seeds | join(",")' < chain.json)
sed -i.bak -e "s/^seeds *=.*/seeds = $seeds/; s/^persistent_peers *=.*/persistent_peers = $peers/" $HOME/.agoric/config/config.toml

8. Set up minimum gas price.

sed -i "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.01ubld,0.005uist\"/;" $HOME/.agoric/config/app.toml

9. Set up pruning (optional).

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.agoric/config/app.toml

10. Create service file.

sudo tee /etc/systemd/system/agd.service > /dev/null <<EOF
[Unit]
Description=Agoric Daemon
After=network-online.target

[Service]
User=$USER
ExecStart=$(which agd) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

11. Enable and start service.

systemctl daemon-reload
systemctl enable agd
systemctl restart agd
journalctl -u agd -f -o cat
