Solana Newbie here.

I am trying to setup an RPC node for extracting data from the Solana chain. However I am having trouble launching the Solana Validator. I feel like I must be missing a dependency or something, but I'm struggling to find it.

When I launch the validator on mainnet-beta:

solana-validator --identity ~/validator-keypair.json --no-voting --rpc-port 8899

I get get the following in the logs:

[2022-10-28T17:49:00.632432080Z INFO  solana_core::validator] Done.

When I look at that directory all I have is: admin.rpc, ledger.lock, and snapshot.

I've tried using version 1.14.6, stable channel, and prebuilt binaries. Any ideas?

You must specify an entrypoint in order to join a network, otherwise, the validator thinks it's starting a new network, and will look for a genesis file.

solana-validator \
  --identity ~/validator-keypair.json \
  --no-voting \
  --rpc-port 8899 \
  --entrypoint entrypoint.mainnet-beta.solana.com:8001

You may also need to specify some known validators from which to fetch a snapshot: https://docs.solana.com/running-validator/validator-start#known-validators

You can find more information at https://docs.solana.com/running-validator/validator-start#connect-your-validator
