Upgrade node running on the host

Upgrading the node is straightforward. Simply install the new version of the node executable file and replace the previous version. Then, stop the currently running node and restart it with the updated version. Node will automatically use the data of your old node and sync the latest blocks that were mined since you shut down the old software.

Running the node requires two binary files: morphnode and geth. Choose to upgrade the binary files according to your specific needs.

Step1: Compile the new version of the code​

git clone https://github.com/morph-l2/morph.git
## checkout the latest version of the source code you need
git checkout ${latestVersion}
## install geth
make geth
## install morphnode
cd ./morph/node && make build

Step2: Stop nodes​

## stop morphnode process
pid=`ps -ef | grep morphnode | grep -v grep | awk '{print $2}'`
kill  $pid

## stop geth process
pid=`ps -ef | grep geth | grep -v grep | awk '{print $2}'`
kill  $pid

Step3: Restart​

Make sure to use the same start-up command you used before the upgrade

## start geth
./morph/go-ethereum/build/bin/geth --morph \
    --datadir "./geth-data" \
    --http --http.api=web3,debug,eth,txpool,net,engine \
    --authrpc.addr localhost \
    --authrpc.vhosts="localhost" \
    --authrpc.port 8551 \
    --authrpc.jwtsecret=./jwt-secret.txt \
    --log.filename=./geth.log

## start geth    
./morph/node/build/bin/morphnode --home ./node-data \
     --l2.jwt-secret ./jwt-secret.txt \
     --l2.eth http://localhost:8545 \
     --l2.engine http://localhost:8551 \
     --log.filename ./node.log
note

For testnet, use --morph-holesky instead
