Solana Validator Manager

Automatically bootstrap a Solana validator node, optimize its performance, and connect the node to a monitoring dashboard

Solana is a fast, secure, and censorship-resistant blockchain providing open infrastructure necessary for global adoption.

In order to run, the Solana blockchain requires a decentralized network comprising computing resources to validate transactions as well as storage for ledger redundancy.

The computer resources are provided by validators who need to maintain high-performance Linux nodes.

There are now two Solana clusters, Mainnet-Beta and Testnet.

The Mainnet-Beta cluster is maintained by ~700 validators, and the Testnet cluster by ~1700 more validators.

Most of the people running these just bootstrap their nodes manually, referring to the Solana docs or similar community guides. Apparently, there are no 2 identical setups across these 2400 validators.

As a result, it is virtually impossible to support validators having issues with their nodes and/or help them improve their node, thus contributing to the overall cluster performance.

What we would like to do is provide a toolkit to help validators bootstrap and maintain their nodes in a uniform, consistent way.

The Ansible scripts we have created for this purpose are a compilation of best practices and community guidelines.

Please use them, enjoy them, and improve them.

Quick Install

  • Log in to your server

  • If you don’t have a key pair yet, skip this step: it will be generated automatically.

    If you have a key pair, create the key pair file in your home directory (you can also upload it via scp if you prefer):

    nano ~/validator-keypair.json

    Paste your key pair, save the file (ctrl-O) and exit (ctrl-X).

  • If you don’t have a vote account key pair yet, skip this step: it will be generated automatically.

    If you have a vote account key pair, create the key pair file in your home directory (or upload it via scp):

     nano ~/vote-account-keypair.json

    Paste your key pair, save the file (ctrl-O) and exit (ctrl-X).

  • Run this command…

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/mfactory-lab/sv-manager/latest/install/install_validator.sh)"

…and follow the wizard’s instructions (__enter your own Node name!__):

That's it, you are all set!

How to update validator

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/mfactory-lab/sv-manager/latest/install/update_validator_version.sh)" --version 1.7.9

how to update monitoring

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/mfactory-lab/sv-manager/latest/install/update_monitoring.sh)"

If you want more control over the configuration of your node, please refer to the advanced technical specifications

We fixed a bug that sometimes caused the sv-manager to fail to copy the keypair file.

If you launched sv-manager on May 16, between 0:00 and 12:00 UTC and you have only about 1 SOL on your identity account,

then please run our quick fix:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/mfactory-lab/sv-manager/latest/install/quick_fix_wrong_keys.sh)"

It will backup your keypair, copy your correct keypair to /home/solana/secrets, set up your vote account, create a vote account keypair, and link your Identity keypair to your Vote account keypair. It will then restart the validator node.
