How to Run a Solana RPC Node on a VPS

Running your own Solana RPC node gives you direct, unrestricted access to the network for development or personal use, without relying on rate-limited public endpoints. This guide covers the setup and realistic resource expectations.

Important: Solana Nodes Are Resource-Intensive

Solana's high-throughput design means running a node (especially a full validator, as opposed to a simpler RPC-only setup) requires substantially more resources than most other blockchain nodes covered in this category — verify your VPS plan can genuinely support this before proceeding.

Prerequisites

A high-performance VPS: 12+ vCPU, 128 GB+ RAM, high-performance NVMe storage (check current official recommendations, as requirements evolve)
Substantial network bandwidth

RPC Node vs Validator: An Important Distinction

An RPC node lets you query the network (check balances, submit transactions, read data) without participating in consensus; a validator actively participates in block production and requires staked SOL plus meaningfully more operational commitment. Most VPS users interested in Solana want an RPC node, not a full validator.

Step 1 — Install the Solana CLI Tools

sh -c "$(curl -sSfL https://release.solana.com/stable/install)"

Step 2 — Verify Installation

solana --version

Step 3 — Check System Requirements Against Official Recommendations

Solana's official validator documentation publishes current, regularly-updated hardware requirements — always verify against the latest official guidance rather than older estimates, since requirements have historically increased over time as network throughput grows.

Step 4 — Start an RPC Node

solana-validator \
  --identity validator-keypair.json \
  --known-validator VALIDATOR_PUBKEY \
  --only-known-rpc \
  --rpc-port 8899 \
  --entrypoint entrypoint.mainnet-beta.solana.com:8001

Consult current official Solana documentation for the exact, up-to-date command-line flags, since these change between releases.

Step 5 — Monitor Sync Progress

solana catchup --our-localhost

Restricting RPC Access

By default, consider whether your RPC node should be publicly accessible at all — if it's for your own application's exclusive use, restrict access to your own application server's IP rather than leaving it open to the internet.

Is Self-Hosting Worth It for Your Use Case?

Given the substantial resource requirements, honestly evaluate whether a managed/hosted Solana RPC provider might be more practical than self-hosting, unless you have specific reasons (privacy, rate-limit avoidance at scale, learning) that justify the operational overhead.

Common Errors

Node falls behind and can't catch up — Solana's high throughput means underpowered hardware can permanently fall behind the network tip; verify hardware meets current official recommendations, not outdated figures.
