Ubuntu Desktop 18 LTS note

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
