In this topic we will help you through the node optimization process, so that validators can earn better rewards by having their nodes run at the optimal levels.
1. Step-1: Stop the running docker
a. Enter command:
cd /opt/validator-node-dockerized
b. Enter command:
docker ps
to check the current running docker.
c. Enter the command:
docker stop etherlite-valnode
to stop running the node
d. Run command: cat .env
This will display the contents of file .env
Copy the Validator node address as we have to add
this in node.toml file
e. Next, to create a file node.toml with the command nano node.toml copy-paste the following configuration settings
#### File node.toml

[rpc]
port = 8545

port = 8546
[account]
password = ["password"]
unlock = [""]
[mining]
engine_signer = ""
reseal_on_txs = "none"
force_sealing = true
f. Following that, add your validator address (the one we
previously copied when we ran the cat.env command) in
the empty fields in front of unlock and engine_signer
and in front of the password field, change it to the
location of your password file
g. After Adding the your validator address Press CTRL+X
you will be asked if you want to save. Enter Y and Press
Enter
2. Step 2 : Start the validator node in screen
a. Use the rm command to remove the unstable build of openethereum by using the following command:
rm -rf openethereum openethereum.zip
b. Download the stable version of openethereum with the following command
curl -SfL 'https://github.com/openethereum/openethereum/releases/download/v3.2.2-rc.1/openethereum-linux-v3.2.2-rc.1.zip' -o openethereum.zip
c. Unzip the downloaded file, enter
unzip openethereum.zip
After you have unzipped the file, openethereum.exe will be available. Give proper permission to run the file
chmod +x openethereum
d. Download the genesis file of EtherLite by entering the command
curl -SfL 'https://raw.githubusercontent.com/etherlite-org/openethereum/etherlite/crates/ethcore/res/chainspec/etherlite.json' -o genesis.json
e. Start the screen by entering the following command
screen -S node
f. Enter the following configuration settings to start the validator node
./openethereum --config=node.toml --jsonrpc-port=8545 --jsonrpc-cors=all --jsonrpc-interface=all --jsonrpc-hosts=all --jsonrpc-apis=web3,eth,net,parity --ws-interface=all --ws-apis=web3,eth,net,parity,pubsub --ws-origins=all --ws-hosts=all --ws-max-connections=10 --max-peers=100
(Note: Above config settings have to be entered in a single unbroken command. Please refer below image for better understanding.)
g. Your validator node will start once the process is started you can safely minimize the screen by entering CTRL+ a + d
3. Step 3: To do a health check of your once you have started it, you can use the following command
curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8545"
