Setup Ngnix + MySQL + Postgres + Redis + RVM + Ruby Version + Ruby On Rails + SSH + Git + Cola + Oh-My-Zsh

Setup.sh

# Step 1 — Installing Nginx
sudo apt-get update
sudo apt-get upgrade -y
sudo apt install nodejs
sudo apt-get install curl git-core nginx -y

# Step 2 — Installing Databases
# before install , update apt-get
$ sudo apt-get update

# choose one or both,
# In MYSQL: 
$ sudo apt-get install mysql-server mysql-client libmysqlclient-dev

# In PostgreSQL
$ sudo apt-get install postgresql postgresql-contrib libpq-dev
# If you want create new super admin in postgres
# 1 - create user 
$ sudo -u postgres createuser <username>

# 2 - alter user password
$ sudo -u postgres psql
psql=# alter user <username> with encrypted password '<password>';

# 3 - modify permissions
psql=# ALTER USER <username> WITH SUPERUSER;


# Step 3 — Installing Redis
# if you ues ubuntu 16.04 run this commend
cd ~
wget http://download.redis.io/releases/redis-stable.tar.gz
tar xzf redis-stable.tar.gz
cd redis-stable
make
make test
sudo make install
cd utils
sudo ./install_server.sh
# if you use ubuntu 18.04 run this commend 
$ sudo apt install redis-server

# Step 4 — Installing RVM
# Before installing RVM, you need to import the RVM GPG Key:
$ gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

# Then install RVM to manage our Rubies:
$ curl -sSL https://get.rvm.io | bash -s stable

# after that :
#  We then need to run the requirements command to automatically install required dependencies and files for RVM and Ruby to function properly:
$ source ~/.rvm/scripts/rvm
$ rvm requirements
# Auto update rvm
$ echo rvm_autoupdate_flag=2 >> ~/.rvmrc

# Step 5 — Installing Ruby 
$ rvm install 2.7.2 # or 2.6.2
$ rvm use 2.7.2 --default

# Step 6 — Installing Rails and Bundler
$ gem install rails
$ gem install bundler
$ gem install mysql2
$ gem install pg

# Step 7 — Setting up SSH Keys
# First shake hands with GitHub, Bitbucket, or any other Git Remote where the codebase for your Rails app is hosted:
$ ssh -T git@bitbucket.org
$ ssh -T git@github.com

# Don't worry if you get a Permission denied (publickey) message. Now, generate a SSH key (a Public/Private Key Pair) for your server:
$ ssh-keygen -t rsa 

# Show ssh key:
$ cat ~/.ssh/id_rsa.pub

# Step 8 — Setting up GIT
# Setup User name and email
$ git config --global user.name 'YourName'
$ git config --global user.email 'YourEmail'

# Step 9 — Setting up Cola
$ apt-get install git-cola

# Step 10 — Setting up Oh-My-Zsh
$ apt-get install zsh

# After that Install Oh-My-Zsh
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

# Than Installation
# 1. Clone the repository:
$ git clone https://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh

# 2. Optionally, backup your existing ~/.zshrc file:
$ cp ~/.zshrc ~/.zshrc.orig

# 3. Create a new zsh configuration file
# You can create a new zsh config file by copying the template that we have included for you.
$ cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

# 4. Change your default shell
chsh -s /bin/zsh

# Note : If it does not work with you, restart your computer

# 5. If you want to add shortcuts (Git - Rails - Bundle etc...)
# First open file ~/.zshrc
$ sudo nano ~/.zshrc
# Than change plugins in file to
plugins=(
  git
  bundler
  rails
  ruby
)

# 6. If You Want Change Theme
# First open file ~/.zshrc
$ sudo nano ~/.zshrc
# Than change ZSH_THEME like this 
ZSH_THEME="robbyrussell"
# OR
ZSH_THEME="agnoster"
