♾️Node guide

Prerequisites

• Operating System: Linux (Ubuntu 22.04 or higher is recommended)

• Hardware Requirements: At least 4 CPU cores, 8 GB RAM, and 500 GB SSD storage

• Dependencies: git, curl, wget, jq, build-essential, go

1. Update System and Install Dependencies

Update your system packages and install necessary dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt install make curl git wget jq build-essential -y

2. Install Go

Download and install Go, which is required to build the node:

ver="1.21.5"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

3. Clone and Build Aligned Layer Node

Clone the Aligned Layer repository and build the node:

cd $HOME
git clone --depth 1 --branch v0.0.2 https://github.com/yetanotherco/aligned_layer_tendermint
cd aligned_layer_tendermint/cmd/alignedlayerd
go build
chmod +x alignedlayerd
sudo mv alignedlayerd /usr/local/bin/

4. Initialize the Node

Initialize your node with a custom moniker (replace NodeName):

alignedlayerd init NodeName --chain-id alignedlayer

5. Download Genesis and Addrbook Files

Download the genesis and addrbook files needed to sync with the network:

wget https://raw.githubusercontent.com/yetanotherco/aligned_layer/main/genesis.json -O $HOME/.alignedlayer/config/genesis.json
wget https://raw.githubusercontent.com/yetanotherco/aligned_layer/main/addrbook.json -O $HOME/.alignedlayer/config/addrbook.json

6. Configure Persistent Peers

Add the necessary peer information to the configuration file:

PEERS="peer_address_1,peer_address_2"
sed -i -e "s|^persistent_peers *=.*|persistent_peers = \"$PEERS\"|" $HOME/.alignedlayer/config/config.toml

7. Start the Node

Start your node using systemd to ensure it runs in the background and restarts on failure:

sudo tee /etc/systemd/system/alignedlayerd.service > /dev/null <<EOF
[Unit]
Description=Aligned Layer Node
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/local/bin/alignedlayerd start
Restart=on-failure
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl enable alignedlayerd
sudo systemctl start alignedlayerd

8. Monitor Node Logs

Check if the node is running properly by monitoring the logs:

journalctl -u alignedlayerd -f

This setup will get your Aligned Layer node running and connected to the testnet. Make sure to follow any additional steps in the official documentation for specific configurations and maintenance tasks.
