How to update

1. Download rskj

Download the latest release from the Github repo.

2. Update jar file

Note that PREVIOUS and NEW refer to version numbers.

cd /usr/share/rsk
sudo service rsk stop
sudo mv rsk.jar rsk-PREVIOUS.jar
sudo mv rskj-core-NEW-all.jar rsk.jar

3. Clean up log directory

This step is optional.

sudo mkdir /var/log/rsk/PREVIOUS/
sudo mv /var/log/rsk/rsk* /var/log/rsk/PREVIOUS/
sudo service rsk start

4. Validate service is running normally

Check logs:

tail -f /var/log/rsk/rsk.log

Check that Blockchain is moving forward, and adding blocks:

curl -s -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_blockNumber", "params": {},  "id":123}' http://127.0.0.1:4444 | jq .result | tr -d '"' | awk '{print "printf \"%d\\n\" "$0}' | sh

If you run this command a few times and the block number is increasing, it means it is syncing correctly too.
