Install node and mongodb on Amazon EC2

First step: Installing node.js and npm

To compile node we need gcc, make and git to import node source code:

sudo yum install gcc-c++ make
sudo yum install openssl-devel
sudo yum install git
Cloning node.js source code:

git clone git://github.com/nodejs/node.git
Compile and install node.js

cd node
./configure 
make
sudo make install
Add user´s directory to BIN Paths (node binaries location)

sudo su
nano /etc/sudoers
inside the editor scroll to where you see the line: Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin

Append the value :/usr/local/bin

Installing npm (Node Package Manager)

git clone https://github.com/npm/npm.git
cd npm
sudo make install
Test if node is working:

node
this must show a > indicator
press Ctrl+C two times to close node interpreter
If you receive a "Command not found" message, close your SSH connection and reconnect. This loads the PATH information you added into /etc/sudoers earlier.

Second step: Install and configure MongoDB database

Based on http://docs.mongodb.org/ecosystem/tutorial/install-mongodb-on-amazon-ec2/
First add an entry to the local yum repository for MondoDB

echo "[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0" | sudo tee -a /etc/yum.repos.d/10gen.repo
You must respect jump of lines in the previous code

Next, install MongoDB and the sysstat diagnostic tools:

sudo yum -y install mongo-10gen-server mongodb-org-shell
sudo yum -y install sysstat
We are using /var/lib/mongo folder to save database, log and journal data, you can another folder path.

sudo mkdir /var/lib/mongo/data
sudo mkdir /var/lib/mongo/log
sudo mkdir /var/lib/mongo/journal
Set the storage items (data, log, journal) to be owned by the user (mongod) and group (mongod) that MongoDB will be starting under:

sudo chown mongod:mongod /var/lib/mongo/data
sudo chown mongod:mongod /var/lib/mongo/log
sudo chown mongod:mongod /var/lib/mongo/journal
Starting and testing MongoDB

Set the MongoDB service to start at boot and activate it:

sudo chkconfig mongod on
sudo /etc/init.d/mongod start
When starting for the first time, it will take a couple of minutes for MongoDB to start, setup it’s storage and become available. Once it is, you should be able to connect to it from within your instance:

$ mongo
MongoDB shell version: 2.4.3
connecting to: test
