Add Plugins#

first we need to install vim plug

curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

use vimplug to install some plugins

call plug#begin()
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
Plug 'prettier/vim-prettier', { 'do': 'yarn install --frozen-lockfile --production' }
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'jiangmiao/auto-pairs'
Plug 'rakr/vim-one'
Plug 'psf/black', {'branch':'stable'}
Plug 'sbdchd/neoformat'
Plug 'navarasu/onedark.nvim'
call plug#end()

Simple Theme#

colorscheme and modification

let g:airline_theme='one'
colorscheme one
set background=dark
:highlight Normal ctermbg=236
:highlight clear LineNr
:highlight clear SignColumn
:highlight clear CursorLineNr
:highlight clear VertSplit
:highlight StatusLine cterm=reverse term=reverse ctermfg=59

paste from clipboard inside tmux

if &term =~ "screen"
  let &t_BE = "\e[?2004h"
  let &t_BD = "\e[?2004l"
  exec "set t_PS=\e[200~"
  exec "set t_PE=\e[201~"
endif

modify cursorline

cursorline
set number
hi CursorLineNr cterm=None
set cursorline
hi CursorLine cterm=None ctermbg=238 guibg=Grey40
let &t_SI = "\e[6 q"
let &t_EI = "\e[2 q"
set ttimeout
set ttimeoutlen=1
set ttyfast

First, install onedark theme using vimplug

" Using Vim-Plug
Plug 'navarasu/onedark.nvim'

Mount Volume EC2#

list device

lsblk

look at the volume of ec2 in aws console as below picture

mount-volume-ec2

run this command to check an file system already exist on the device and parition or not

sudo file -s /dev/sdf1

if an file system already exist, let create a new directory

sudo mkdir /data

then mount

sudo mount /dev/sdf1 /data

configure auto mount on startup

sudo cp /etc/fstab /etc/fstab.orig

check the UUID

sudo blkid

take note the UUID

f33e7d3b-6786-4f40-875a-90f0f7e6b9a8

update the /etc/fstab file by appending this line to the end

UUID=aebf131c-6957-451e-8d34-ec978d9581ae  /data  xfs  defaults,nofail  0  2

verify that mount working

sudo umount /data
sudo mount -a

User Data#

#!/bin/bash
cd ~
wget -O ~/.vimrc https://raw.githubusercontent.com/cdk-entest/basic-vim/main/.vimrc 
wget https://github.com/cdk-entest/flask-tailwind-polly/archive/refs/heads/master.zip 
unzip master.zip
cd flask-tailwind-polly-master
python3 -m ensurepip --upgrade
python3 -m pip install -r requirements.txt

  • Grow parition
  • Extend file system

First grow parition

sudo growpart /dev/nvme0n1 1

Then extend file system and the command depends on type of file system

sudo resize2fs /dev/nvme0n1p1

Port Forwarding#

For web development, we can run a webserver (nextjs) on ec2 and use portforwarding so local machine can access i

ssh -L 3000:localhost:3000 ec2-user@cloud9
