Install Ruby & Rails

rvm install 2.2.0
rvm --default use 2.2.0

# Install bundler
gem install bundler

# Install Rails 
gem install rails --version 4.2.0 --no-ri --no-rdoc

Install Apache

yum -y install httpd httpd-devel

# Allow port 80 to server webpage
iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT

# starts the service
chkconfig httpd on
service httpd start

# Install passenger
# There will be more requirements to install
# Just follow the instructions
gem install passenger
passenger-install-apache2-module
# There will be instructions to load your passenger module via http conf
# Put the config in a new file at /etc/httpd/conf.d/passenger.conf, it should be look like:

/etc/httpd/conf.d/passenger.conf

Setup Postgres in Server

yum install postgresql96 postgresql96-server  postgresql96-devel postgresql96-contrib  postgresql96-docs postgresql96-libs

service postgresql96 initdb
chkconfig postgresql96 on
service postgresql96 restart

# Create the user
sudo -u postgres psql
create user <username> with password '<password>';
create database myapp_production owner <username>;
ALTER ROLE <username> SUPERUSER; # Needed if your app needs to install extensions

# Type '\q'+Enter to exit postgres

# Change PG login
vi /var/lib/pgsql96/data/pg_hba.conf
# Change the bottom lines from Ident to md5
# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               md5
# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5
# Restart the service
service postgresql96 restart

Pre-deployment

in2ideas is the assumed name of the project in this guide

# Setup a user for the access (instead of root)
adduser in2ideas
passwd -l in2ideas
# This locks the password of in2ideas.
# Use public key to access SSH.
# Read section Access SSH via Public Key below

# add t rvm group so that bundling can work for capistrano
usermod -a -G rvm in2ideas

# set directory for the app
deploy_to=/home/in2ideas/production
mkdir -p ${deploy_to}
chown in2ideas:in2ideas ${deploy_to}
umask 0002
chmod g+s ${deploy_to}
mkdir -p ${deploy_to}/{releases,shared}

# Use your user (not root) to do the below:
rvm gemset create <gemset>
rvm gemset use <gemset>

Setup Git on Server

This setups the git server on the remote server Developer will push to this folder (~/git/in2ideas.git) and Capistrano will pull from this folder and deploy it

# switch to user mode
su in2ideas
mkdir -p ~/git/in2ideas.git
cd ~/git/in2ideas.git
git --bare init

Next, we need to setup the SSH for Capistrano to access the Git:

test -e ~/.ssh/id_dsa.pub || ssh-keygen -t dsa # Enter 3 times
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

# Need to do this for CentOS
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys 
restorecon -Rv ~/.ssh

# Accepting host authenticity for user
# Test it (you need to accept the host authenticity):
ssh localhost
# if you did not see any prompt for password, it is done!

# Test: accept host authenticity for git
git ls-remote ssh://user@domain/~/git/in2ideas.git master

Access SSH via authorized_keys

# Your localhost iTerm:
vim ~/.ssh/id_rsa.pub # Copy a key
# ssh iTerm(user mode):
vim ~/.ssh/authorized_keys # Paste to here
