Server Setup Quickstart

• Install generally useful server utils:

  • sudo apt update && apt install -y zip gzip iputils-ping traceroute htop tmux neovim tcpdump gh wireguard resolvconf

• Log into github

  • gh auth login

• Install docker

  • curl -fsSL https://get.docker.com | sh

• Install golang

  • curl -fsSLo- https://s.id/golang-linux | bash

• Install tailscale

  • curl -fsSL https://tailscale.com/install.sh | sh
    tailscale up

• Set up subdomains with SSL:
  1. Install nginx and certbot

  sudo apt install -y nginx certbot python3-certbot-nginx

  2. Set /etc/nginx/sites-enabled/default to:

  server {
      listen 80;
      server_name subdomain1.domain.com;
  
      # Require basic authentication for all requests
      auth_basic "Restricted Area";
      auth_basic_user_file /etc/nginx/.htpasswd;
  
      # Proxy requests
      location / {
          proxy_set_header Host $host;
          proxy_pass http://127.0.0.1:3434;
          proxy_redirect off;
      }
  }
  server {
      listen 80;
      server_name subdomain2.domain.com;
      
      # Require basic authentication for all requests
      auth_basic "Restricted Area";
      auth_basic_user_file /etc/nginx/.htpasswd;
  
      # Proxy requests
      location / {
          proxy_set_header Host $host;
          proxy_pass http://127.0.0.1:3435;
          proxy_redirect off;
      }
  }
  ...

  3. htpasswd -c /etc/nginx/.htpasswd admin
     sudo certbot --nginx -d subdomain1.domain.com -d subdomain2.domain.com
     sudo service nginx restart

• Generate random passwords

  • openssl rand -hex 16

• Move files around
  1. Compress files

  tar -czvf files.tar.gz /path/src

  2. SCP files between hosts

  scp /local/dst user@remote:/src

  3. Decompress files

  tar -xvzf files.tar.gz -C /local/dst
