Setting up linode Arch Linux

Blindly run these steps once you have a brand new Arch Linux Server in linode.

1. Connect to your Linode via SSH:

   ssh root@IP
   

2. Set your timezone and synchronize the hardware clock with the system clock:

   ln -sf /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
   hwclock --systohc
   date
   

3. Create a new user and set sudo permissions:

   useradd -m pdebashis
   passwd pdebashis
   export EDITOR="vim"
   visudo
   --- add the line "pdebashis ALL=(ALL) ALL"
   

4. Switch to the newly created user

   su - pdebashis
   vim ~/.bashrc
   --- setup `.bashrc` file as per `my_bashrc`
   https://github.com/pdebashis/my-bashrc
   source .bashrc
   

5. Update the system and install some basic packages:

   sudo pacman -Syyu
   sudo pacman -S --needed base-devel
   sudo pacman -S git wget
   sudo pacman -S jdk-openjdk
   sudo pacman -S scala
   sudo pacman -S cronie
   

6. Install yay (AUR Helper):

   git clone https://aur.archlinux.org/yay.git
   cd yay
   makepkg -si
   cd ..
   rm -rf yay
   

7. Install Ruby:

   --- Go to the RVM website and install RVM only (no --ruby).
   rvm install 3.1.0
   --- Note: Older Ruby versions may be broken by OpenSSL dependency.
   

8. Install Jupyter Notebook and iruby:

   --- Follow a guide for Jupyter notebook
   --- Install iruby gem for ruby notebook
   gem install iruby
   --- Test it
   iruby notebook
