Скрипт для запуска seed ноды тестнета

Скрипт можно использовать как boot startup script в облачном хостинге, например, в https://vultr.com/.

При необходимости поменять размер swap, дополнить config делегатом/плагинами.

#!/bin/sh
fallocate -l 10G /swapfile
ls -lh /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
swapon --show

mount -o remount,size=10G /dev/shm
mount -l | grep "/dev/shm"

free -h
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
cat /etc/fstab

sysctl vm.swappiness=80
sysctl vm.vfs_cache_pressure=50
echo "vm.swappiness=80" >> /etc/sysctl.conf
echo "vm.vfs_cache_pressure=50" >> /etc/sysctl.conf
tail /etc/sysctl.conf

Проверка статуса билда vizd: cat /viz/viz-world/build/buildlog_vizd.txt

Проверка вывода сессии ноды: cat /viz/viz-world/build/programs/vizd/screenlog.0

Вернуться в сессию ноды: screen -x vizd

Вернуться в консоль: Ctrl+A+D, завершить работу ноды: Ctrl+C
