Installing Arch Linux On a Vultr Server

Installing Arch Linux On a Vultr Server

This is a minimal installation guide targeted to get Arch Linux running on Vultr. For simplicity, 'time zone', 'hostname', 'locale' and 'initramfs' are omited, you can configure them latter by yourself.

Partition the disks

For simplicity, we use single root partition.

# fdisk /dev/vda

How to list open SSH tunnels — First published in fullweb.io issue #34

How to list open SSH tunnels?

Very often a database in production only accept connections from localhost, and we resort to use SSH tunneling to access it remotely. While tunnels are running in the background and we connect to the database on localhost, we need to know if we’re really talking to our localhost or to the remote machine.

example for connect remote elasticsearch server

ssh -C -f -N -g -L 9200:127.0.0.1:9200 user@ipaddress

How to set up git to use the GPG Suite

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

  1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
  2. Create or import a key -- see below for https://keybase.io
  3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
  4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys
