Update Prysm client

Update client

Check current version of Prysm running on the server:

cd /usr/local/bin

• Beacon chain:

  ./beacon-chain --version

• Validator:

  ./validator --version

1. Find the latest stable version of Prysm on Github
   • Find latest Prysm version at https://github.com/prysmaticlabs/prysm/releases
   • Write latest stable Prysm version:
     

     This will update the url links in the guide below.

2. Download Prysm clients to your node

   cd ~/downloads && curl -LO https://github.com/prysmaticlabs/prysm/releases/download/v6.0.4/beacon-chain-v6.0.4-modern-linux-amd64

   cd ~/downloads && curl -LO https://github.com/prysmaticlabs/prysm/releases/download/v6.0.4/validator-v6.0.4-linux-amd64

3. Rename downloaded files

   mv beacon-chain-v6.0.4-modern-linux-amd64 beacon-chain && mv validator-v6.0.4-linux-amd64 validator

4. Set files permissions

   chmod +x beacon-chain && chmod +x validator

5. Stop running clients

   You can time this based on validator duties either from validator instances log(s) or for Ethereum also from sources such as WenMerge.com or ETHStakers.

   // Stop all validator instances using Prysm clients on all chains
   // sudo systemctl stop prysmvalidator1
   // sudo systemctl stop prysmvalidator2
   // sudo systemctl stop prysmRocketpoolValidator
   // sudo systemctl stop prysmStakewiseValidator
   // ...
   // Stop beaconchain clients using PrysmBeacon client on all chains
   sudo systemctl stop prysmbeacon

   /usr/local/bin/staking.sh stop consensus

   Check the services

   /usr/local/bin/staking.sh check

6. Copy clients to /usr/local/bin

   sudo cp ~/downloads/beacon-chain /usr/local/bin

   sudo cp ~/downloads/validator /usr/local/bin

7. Start services using Prysm clients

   // Start all validator instances using Prysm clients on all chains
   // sudo systemctl start prysmvalidator1
   // sudo systemctl start prysmvalidator2
   // sudo systemctl start prysmRocketpoolValidator
   // sudo systemctl start prysmStakewiseValidator
   // ...
   // Start beaconchain clients using PrysmBeacon client on all chains
   sudo systemctl start prysmbeacon

   /usr/local/bin/staking.sh start consensus

   Check the services status

   /usr/local/bin/staking.sh check

8. Monitor

   journalctl -fu prysmbeacon.service

   journalctl -f -u prysmvalidator.service -u prysmvalidator2.service

   ...

   /usr/local/bin/staking.sh check consensus

   /usr/local/bin/staking.sh monitor consensus

9. Remove downloaded files

   cd ~/downloads && rm beacon-chain && rm validator
