Bu qo'llanmada qanday qilib Ubuntu 14.04 ga mashhur veb freymvork Ruby on Rails ni o'rnatishni o'rganamiz. Nega Ubuntu 14.04? Chunki bu eng barqaror va LTS (long term support) ya'ni uzoq vaqt qo'llab quvvatlash. Ubuntu 14.04 2019-yilgacha qo'llab quvvatlanadi. Agar siz eski versiyada bo'lsangiz apdeyt qilishni maslahat beraman.

Ishga kirishsak. Ruby va Rails ni eng so'ngi barqaror versiyasini o'rnatishni eng oson yo'li RVM dasturi orqali amalga oshirsa bo'ladi.
Ruby ni o'rnatishdan oldin ba'zi zarur dasturlarni ornatamiz:
Terminalni ochamiz (Ctrl+Alt+T):

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev

Endi RVM orqali Ruby ni o'rnatamiz:

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
rvm install 2.1.1
rvm use 2.1.1 --default
ruby -v

Rails ni o'rnatamiz:
Rails juda ko'p dasturlaga qaram bo'ladi, ularsiz to'g'ri ishlashiga kafolat yo'q, shulardan biri NodeJS.
NodeJS ni o'rnatish uchun oldin repositorni qo'shamiz:

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

Endi Rails ni o'rnatamiz:

gem install rails

rails -v
# Rails 4.1.0

MySQL ni sozlash:
MySQL ni Ubuntu repositordan o'rnatishingiz mumkin

sudo apt-get install mysql-server mysql-client libmysqlclient-dev

PostgreSQL ni sozlash:
PostgreSQL uchun repositor qo'shish shart

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-common
sudo apt-get install postgresql-9.3 libpq-dev

PostgreSQL uchun foydalanuvchi yaratilishi shart:

sudo -u postgres createuser username -s
# agar parol qo'ymoqchi bo'lsangiz
sudo -u postgres psql
postgres=# \password parol

Endi tekshirib ko'ramiz:

#### Agar MySQL dan foydalanmoqchi bo'lsangiz
rails new new_app -d mysql
 
#### Agar Postgres dan foydalanmoqchi bo'lsangiz
rails new new_app -d postgresql
 
# Dastur papkasi
cd new_app
 
# Agar MySQL yoki Postgres foydalanuvchi/parol yaratgan bo'lsangiz,
# config/database.yml falidan sozlashingiz mumkin
# Ma'lumotlar bazasi yaratamiz
rake db:create
 
rails server

Bo'ldi. Endi localhost:3000/ o'tib tekshirib ko'rishingiz mumkin.
Chiroyli dasturlash tilayman!
