Подготавливаем сервер

sudo apt update && sudo apt upgrade -y
sudo apt install nano curl jq logrotate git bc -y

Предварительные проверки сервера

Проверяем диски

curl -sL yabs.sh | bash -s — -ig

Смотрим запись/чтение 4к файлов, скорость должна быть выше 500мб/с (это минимум, который возможно даже будет не достаточным).

Проверяем износ дисков

Выводим список дисков

lsblk

Далее ставим тулз для проверки дисков + по каждому диску смотрим инфу (износ, температура, объем)

apt install smartmontools
smartctl -a /dev/nvme0n1

Проверяем скорость интернета

Скорость должна быть выше 500 мбит/с

curl -sL yabs.sh | bash -s — -fg

Проверяем оперативку

apt install memtester
free -m #получаем объем свободной памяти и тестируем его, если памяти свободной мало, то рестарт сервера
memtester 100G 1

Создаем SWAP файл

swapoff -a
dd if=/dev/zero of=/swapfile bs=1G count=300
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
nano /etc/fstab

Закомментировать символом # строку, в которой содержится слово swap (существующий SWAP файл)

Добавить в конец файла две строки:

/swapfile none swap sw 0 0
tmpfs /mnt/ramdisk tmpfs nodev,nosuid,noexec,nodiratime,size=300G 0 0

Монтриуем RAM диск

mkdir -p /mnt/ramdisk
mount /mnt/ramdisk

Устанавливаем Solana CLI

Перед установкой проверить актуальную версию ПО в гитхабе

touch $HOME/.bash_profile
sh -c "$(curl -sSfL https://release.solana.com/v1.18.17/install)"
. $HOME/.bash_profile

Подготоваливаем валидатор

Перед запуском заменить RPC url на нужный

solana config set --url http://api.testnet.solana.com
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

Добавить в system.conf строку DefaultLimitNOFILE=1000000

sudo nano /etc/systemd/system.conf

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

echo "----------- Create solana folder -----------"
mkdir -p $HOME/solana

Связываем ключи валидатора

Перенести аккаунт testnet-validator-keypair.json, созданный при регистрации, в папку solana.

echo "----------- Add testnet-validator-keypair.json to config -----------"
solana config set --keypair $HOME/solana/testnet-validator-keypair.json

echo "----------- Request airdrop to validator address -----------"
solana airdrop 1

echo "----------- Create Vote account -----------"
solana-keygen new -o $HOME/solana/vote-account-keypair.json

echo "----------- Create Withdrawer account -----------"
solana-keygen new -o $HOME/solana/authorized-withdrawer-keypair.json

echo "----------- Connect all accounts -----------"
solana create-vote-account $HOME/solana/vote-account-keypair.json \
  $HOME/solana/testnet-validator-keypair.json \
  $HOME/solana/authorized-withdrawer-keypair.json --commission 10

Создание стейк аккаунта

solana-keygen new -o /root/solana/validator-stake-keypair.json

solana create-stake-account /root/solana/validator-stake-keypair.json 101 --stake-authority /root/solana/authorized-withdrawer-keypair.json --withdraw-authority /root/solana/authorized-withdrawer-keypair.json

solana delegate-stake /root/solana/validator-stake-keypair.json /root/solana/vote-account-keypair.json --stake-authority authorized-withdrawer-keypair.json

Сохраняем резервную копию ключей на компьютере.

Удаляем witdrawer ключ:

rm $HOME/solana/authorized-withdrawer-keypair.json

Настраиваем ротацию логов

sudo tee <<EOF >/dev/null $HOME/solana/solana.logrotate
$HOME/solana/solana.log {
  rotate 1
  daily
  missingok
  postrotate
    systemctl kill -s USR1 solana.service
  endscript
}
EOF
rm -rf /etc/logrotate.d/sol
ln -s $HOME/solana/solana.logrotate /etc/logrotate.d/sol
sudo systemctl restart logrotate
