The installation time depends on many factors, such as your skills, resources and characteristics of your server, the most important: disk speed, internet connection, server load CPU, RAM, so this value may differ from the one indicated by us.
With the help of a one-line script, all the necessary commands will be executed automatically, you only need to check the operation of your node at the end, for this, go directly to 📌Step 3: Node Health Check
📝 Manual installation
📌Step 1: Installation packeges and dependencies
# Install dependencies for building from source
sudo apt update
sudo apt install -y lz4 jq make git gcc build-essential curl chrony unzip gzip snapd tmux bc
# Install Go if you need
sudo rm -rf /usr/local/go
curl -L https://go.dev/dl/go1.21.6.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source .bash_profile
📌Step 2: Set moniker and install node
Give your validator a name by which you can find yourself in explorer, put it in ""
MONIKER=""
After that, insert the following node installation command
# Clone project repository
cd $HOME
rm -rf 0g-chain
git clone https://github.com/0glabs/0g-chain.git
cd 0g-chain
git checkout v0.4.0
git submodule update --init
make install
# Set node CLI configuration
0gchaind config chain-id zgtendermint_16600-2
0gchaind config keyring-backend test
0gchaind config node tcp://localhost:26657
# Initialize the node
0gchaind init "$MONIKER" --chain-id zgtendermint_16600-2
# Download genesis and addrbook files
wget https://snapshots-testnet.unitynodes.com/0gchain-testnet/addrbook.json -O $HOME/.0gchain/config/addrbook.json

📌Step 3: Node Health Check
Follow the commands to check if your node is working properly
If you have successfully created a validator, be sure to save your validator.
Show priv_validator_key.json
cat $HOME/.0gchain/config/priv_validator_key.json
SAVE YOUR PRIVATE KEY AFTER ENTERING THE COMMAND
The priv_validator_key.json is the key with which you can always restore the operation of your validator, so keep it and in case of reinstallation/transfer of the validator to another server - transfer it too.
Also remember, if you are a validator with a sufficient number of delegated tokens and you are in an active set, signing blocks, always save priv_validator_state.json - this file contains information about the signed blocks of your validators, and in case of restoring the validator after reinstallation or on another server , this file won't give you the old blocks again, otherwise you'll end up in jail with no way out
💡 Hint:
Validator state directory: $HOME/.0gchain/data/priv_validator_state.json
We open the 🚰 and request tokens to the metamask address we received
After entering the command, you will receive hash transactions, check the status in the if the status is successful - you have created a validator.
You can find your validator here: In the Active / Inactive lists.
