System Requirements

Operating System

• Ubuntu Server 22.04.4 LTS

Hardware Requirements

Configuration	CPU	RAM	SSD
Low-End	64-core	512GB	10TB
Mid-Range	128-core	1T	15TB

Server Port Policy

• Open ports 80 and 443 for RPC external services.

• Open TCP and UDP protocol ports in the range of 8000 to 9000.

• Whitelist IP addresses 52.13.90.86.

After configuration, send your server's public IP address to [e-mail].

System Tuning

Your system needs to be tuned to run properly. Your RPC validator may not start without these settings.

Optimize sysctl knobs:

sudo bash -c "cat >/etc/sysctl.d/21-solana-validator.conf <<EOF
# Increase UDP buffer sizes
net.core.rmem_default = 134217728
net.core.rmem_max = 134217728
net.core.wmem_default = 134217728
net.core.wmem_max = 134217728

# Increase memory mapped files limit
vm.max_map_count = 1000000

# Increase number of allowed open file descriptors
fs.nr_open = 1000000
EOF"

sudo sysctl -p /etc/sysctl.d/21-solana-validator.conf

Increase systemd and session file limits:

Add to the [Service] section of your systemd service file:

LimitNOFILE=1000000

Or add to the [Manager] section of /etc/systemd/system.conf:

DefaultLimitNOFILE=1000000

Then run:

sudo systemctl daemon-reload

sudo bash -c "cat >/etc/security/limits.d/90-solana-nofiles.conf <<EOF
# Increase process file descriptor count limit
* - nofile 1000000
EOF"

Important: Close all open sessions. Log out then log in again after making these changes.

Install BARA Testnet Validator

Option 1: Pre-built Binary Package

wget https://grid-sonic.hypergrid.dev/downloads/sonic_testnet_grid_v1.tar.gz
tar -zxvf sonic_testnet_grid_v1.tar.gz

Option 2: Build from Source Code

1. Install dependencies:

curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
rustup component add rustfmt

sudo apt-get update
sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler

2. Download the source code:

git clone https://github.com/mirrorworld-universe/hypergrid-grid
cd hypergrid-grid
git checkout base_on_1.18.23

3. Build

mkdir ~/sonic_node
./scripts/cargo-install-all.sh ~/sonic_node
cp ./start_node.sh ~/sonic_node/
cp ./stop_node.sh ~/sonic_node/

Initialization

cd ~/sonic_node
mkdir config
mkdir logs

./bin/solana-keygen new --no-passphrase
./bin/solana config set --url http://127.0.0.1:8899
./bin/solana-keygen new -o ./config/validator-keypair.json

Check System Variables

cat /proc/sys/net/core/rmem_default
cat /proc/sys/net/core/rmem_max
cat /proc/sys/net/core/wmem_default
cat /proc/sys/net/core/wmem_max
cat /proc/sys/vm/max_map_count
cat /proc/sys/fs/nr_open
cat /proc/sys/fs/file-max
cat /proc/sys/vm/swappiness

Configuration

Edit the start_node.sh file and replace YOUR_PUBLIC_IP with your machine's public IP address.

This script contains various configuration options. Ensure you replace YOUR_PUBLIC_IP with your actual public IP address, VALIDATOR_ID, with the public address of the known validator on the cluster, and VALIDATOR_GENESIS_HASH with the genesis hash of the cluster you are deploying for.

mkdir -p /data/logs
mkdir -p /data1/accounts
mkdir -p /data/ledger

Make sure to replace YOUR_PUBLIC_IP with your actual public IP address, and replace VALIDATOR_ID and VALIDATOR_GENESIS_HASH with the right values.

Configuring Domain Name for your RPC Node

At this point, you should be ready to configure a domain name for your service. You may use Nginx or any reverse proxy of your choice.

Running the Node

./start_node.sh

Shutting Down the Node

You can gracefully shut down the node by running the following command inside the ~/sonic_nodedirectory

./stop_node.sh

Operator Guides

It is recommended to read the guides and operator best practices outlined in the official Solana documentation.
