Prelude#

This article is mainly to record the stuff to do post Ubuntu Desktop 18.04 Installation.

Purpose#

All actions post installation is to make the Ubuntu Desktop a wonderful toolkit for developer.

Prerequisite#

  • Install all essentials
sudo apt install -y git curl
sudo apt-get install -y apt-transport-https ca-certificates      gnupg-agent
sudo apt install -y software-properties-common

Install & Setup Zsh#

  • Install Zsh
sudo apt install -y zsh
  • Setup Zsh

I prefer Prezto Zsh, which is the minimal version of Oh-My-Zsh. In my opinion, Oh-My-Zsh is kind of slow and sort of overblown.

  • Create a script setup_prezto.zsh
  • Save the code below to the scirpt and run zsh ./setup_prezto.sh && source ~/.zshrc

git clone --recursive https://github.com/sorin-ionescu/prezto.git \
    "${ZDOTDIR:-$HOME}/.zprezto"

setopt EXTENDED_GLOB
for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
    ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
done


if [ -d ~/.zprezto ];then
    cp  ubt18/z* ~/.zprezto/runcoms/
fi

[[ ! -d ~/.zprezto-contrib ]] && mkdir -p ~/.zprezto-contrib;

sudo -R $UsER:$USER .zprezto
sudo -R $UsER:$USER .zprezto-contrib

chsh -s /bin/zsh

echo "Setup finished."
echo "Please reboot or restart terminal."

Install & Setup Vim with useful plugins#

  • Install Vim
sudo apt install -y vim
  • Setup Vim with some amazing plugins

There are many different vim plugins available online. There is a plance callded Vim Awesome, which you can find anything you want.

My favorite option is the Junegunn’s Vim plugins. I like the simplicity of this solution.

  • Prepare the vimrc as below
set nu

colorscheme delek

:imap jj <Esc>
:imap jk <Esc>
:imap kj <Esc>
:imap ii <Esc>

" Specify a directory for plugins
" - For Neovim: ~/.local/share/nvim/plugged
" - Avoid using standard Vim directory names like 'plugin'
call plug#begin('~/.vim/plugged')

" Make sure you use single quotes

" Shorthand notation; fetches https://github.com/junegunn/vim-easy-align
Plug 'junegunn/vim-easy-align'

" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-github-dashboard.git'

" Multiple Plug commands can be written in a single line using | separators
Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'

" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Using a non-master branch
Plug 'rdnetto/YCM-Generator', { 'branch': 'stable' }

" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }

" Plugin options
Plug 'nsf/gocode', { 'tag': 'v.20150303', 'rtp': 'vim' }

" Plugin outside ~/.vim/plugged with post-update hook
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
Plug 'Shougo/vimproc.vim', { 'do': 'make' }


function! BuildYCM(info)
  " info is a dictionary with 3 fields
  " - name:   name of the plugin
  " - status: 'installed', 'updated', or 'unchanged'
  " - force:  set on PlugInstall! or PlugUpdate!
  if a:info.status == 'installed' || a:info.force
    !./install.py
  endif
endfunction

Plug 'Valloric/YouCompleteMe', { 'do': function('BuildYCM') }

" Plug 'Valloric/YouCompleteMe', { 'do': './install.py' }

Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }

" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'

" Initialize plugin system
call plug#end()

Install MySql#

  • Here I just install the default MySql 5.7. If you want to install the new version or MariaDB, please check out the official website.
# Install MySql server and client
sudo apt install mysql-server mysql-client

# Check if the MySql service active and running
sudo systemctl status mysql.service

# Enable or Restart MySql service
sudo systemctl enable mysql.service
sudo systemctl restart mysql.service

# Create root account
sudo mysql_secure_installation

# After the password for root has been created
sudo mysql -u root -p

# Update the password via mysql comomand pompt
mysql>ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_strong_password';

# Create another admin is highly recommended in production env
mysql>GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'your_strong_password';

Install Java#

  • Install AdoptOpenJDK for Linux

    # Download tarball you need
# Unzip the tarball

tar xzf OpenJDK11U-jdk_x64_linux_hotspot_x.y.z.tar.gz

sudo mv OpenJDK11U-jdk_x64_linux_hotspot_x.y.z.tar.gz  \
    /usr/lib/jvm/OpenJDK11U-jdk_x64_linux_hotspot_x.y.z

sudo apt install update-java-alternatives

# Check alternative JDK 
install update-java-alternatives -l

adoptopenjdk-11-hotspot-amd64  1111   /usr/lib/jvm/adoptopenjdk-11-hotspot-amd64
adoptopenjdk-14-hotspot-amd64  1141   /usr/lib/jvm/adoptopenjdk-14-hotspot-amd64
adoptopenjdk-8-hotspot-amd64   1081   /usr/lib/jvm/adoptopenjdk-8-hotspot-amd64

# Switch JDK
update-java-alternatives -s adoptopenjdk-xx-hotspot-amd64
