Configuration Setup

Creating a deploy user

Create username and password

useradd deploy
passwd <password>

Add the deploy user to the list of sudoers by typing visudo and pasting this line:

deploy ALL=(ALL) ALL

To ensure that paths stay the same when running in sudo, change secure_path in visudo to:

Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/home/deploy/.rbenv/shims

Proxy Setup

Add these two lines to your .bashrc to set proxy environment variables

export https_proxy=https://proxy.unhcr.local:8080
export http_proxy=http://proxy.unhcr.local:8080

Deploy Setup

Create /var/www/ folder and have deploy user own it.

mkdir /var/www/
chown deploy /var/www

Auto SSH login

On your local computer run:

ssh-keygen -t rsa

Create .ssh folder on your remote server

ssh deploy@<remote_server> mkdir -p .ssh
chmod 700 .ssh

Now again from your local computer:

cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys2 && chmod 640 .ssh/authorized_keys2'

Installation Requirements

Ruby

As a ruby environment manager we'll using rbenv. The installation instructions are found on that page. Attempt to use ruby-build to install 2.0.0-p353. As of now there is a bug that is noted here.

If the proposed fix didn't work follow the next steps (Skip this part if ruby successfully installed).

cd ~/.rbenv/versions/

Now download ruby version 2.0.0-p353.

wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p353.tar.gz

Unzip the tar and install. Once you've installed ruby, you'll want to add the gem binary to your path. Insert this into your .bashrc:

export PATH=$PATH:$HOME/.rbenv/bin

tar -zxvf ruby-2.0.0-p353.tar.gz
cd ruby-2.0.0-p353
./configure
make
sudo make install
rm ruby-2.0.0-p353.tar.gz

Nginx-passenger

Next we need to setup Nginx passenger. For this use the guide here. Complete steps 1 and 2 only.

Mysql

yum install mysql mysql-devel

Sqlite3

yum install sqlite3-devel

ElasticSearch

wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.11.noarch.rpm`
rpm -i elasticsearch-0.90.11.noarch.rpm

Whenever gem

This sets up cron jobs for the weekly build. https://github.com/javan/whenever

gem install whenever

phantomjs

cd ~
wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-x86_64.tar.bz2
tar xvjf phantomjs-1.9.7-linux-x86_64.tar.bz2
sudo cp phantomjs-1.9.7-linux-x86_64/bin/phantomjs /usr/local/bin

redis

cd ~
wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make
sudo cp src/redis-benchmark /usr/local/bin/
sudo cp src/redis-cli /usr/local/bin/
sudo cp src/redis-server /usr/local/bin/
sudo cp redis.conf /etc/
sudo sed -i 's/daemonize no/daemonize yes/' /etc/redis.conf
sudo sed -i 's/^pidfile \/var\/run\/redis.pid/pidfile \/tmp\/redis.pid/' /etc/redis.conf
