cosmovisor is a process manager for Cosmos SDK application binaries that automates application binary switch at chain upgrades. It polls the
upgrade-info.json file that is created by the x/upgrade module at upgrade height, and then can automatically download the new binary, stop the current binary, switch from the old binary to the new one, and finally restart the node with the new binary.go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]
mkdir -p ~/.mantrachain/cosmovisor/genesis/bin
mkdir -p ~/.mantrachain/cosmovisor/upgrades
cp ~/bin/mantrachaind ~/.mantrachain/cosmovisor/genesis/bin
The
systemd service manager allows the mantrachaind binary to run as a service, instead of as a command-line application. (See https://systemd.io for more information.)sudo tee /etc/systemd/system/mantrachaind.service > /dev/null << EOF

Once started, the node will take some time to sync with the blockchain.
Visit https://explorer.testnet.mantrachain.io/mantrachain to see the current height of the blockchain. Use the
journalctl command to check on the node's progress.Last modified 24d ago
