hashtagsell-deploy #Sell2014

Setup

Prerequisites

  • Ubuntu 14.04LTS x64 Server
  • Primary volume sized to 16G
  • For Mongo - secondary volume sized to 1T
  • Add to appropriate security group (stage-hashtagsell-data or stage-hashtagsell-api)

Basic Server Setup Steps

sudo apt-get update && sudo apt-get dist-upgrade -y
# note: when the grub menu prompt appears, choose the "keep" option
sudo apt-get install build-essential git -y

MongoDB Server

After completing the above basic server setup steps, do the following steps to complete setup of MongoDB:

Prepare Secondary Volume

Run the following command and make note of the 1T (or large) volume that exists on the server:

lsblk

The above will produce something similar to:

ubuntu@ip-172-31-4-65:/$ lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0  16G  0 disk
└─xvda1 202:1    0  16G  0 part /
xvdb    202:16   0   1T  0 disk

Prepare the appropriate volume's (in the above example, xvdb) filesystem:

sudo mkfs -t ext4 /dev/xvdb

Now create a folder for the volume and mount it:

sudo mkdir /data
sudo mount /dev/xvdb /data

To ensure the drive will exist after a reboot, make a copy of the /etc/fstab file and then edit it:

sudo cp /etc/fstab /etc/fstab.orig

Now add the following line to the file:

/dev/xvdb 	/data 	 ext4 	defaults,nofail 	0 2

Now verify the mount is properly configured:

sudo mount -a

Ensure mongo has permissions to the mount folder:

sudo chown -R mongodb:mongodb /data

Install and Configure Mongo

sudo apt-get install mongodb -y

Now edit /etc/mongodb.conf and ensure the following values are set:

# mongodb.conf

# Where to store the data.
dbpath=/data

# Where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true

# bind_ip = 127.0.0.1
port = 27017

# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true

# Disable the HTTP interface (Defaults to localhost:27018).
nohttpinterface = true

Now stop and start mongo:

sudo service mongodb stop
sudo service mongodb start

API Server

After completing the above basic server setup steps, do the following steps to complete setup of the API server:

Compile and Install Node

Do the following... grab a coffee, it will take a while:

mkdir ~/source
cd ~/source
git clone https://github.com/joyent/node.git
cd node
git checkout v0.10.35
./configure && make && sudo make install

SSH Deployment Key

In order to access HashtagSell code in GitHub, the SSH deployment key must be added to the server. Create a file at ~/.ssh/id_rsa with the following contents:

Install Nginx

For SSL termination and Node application proxying, Nginx is used. To install it, perform the following:

sudo apt-get install nginx -y

Install and Configure Postings-API

cd ~/source
git clone [email protected]:HashtagSell/posting-api.git
cd posting-api.git
npm install
sudo npm install -g bunyan
sudo npm install -g gulp

Now to configure:

mkdir ~/source/posting-api/config
touch ~/source/posting-api/config/production.json

Now edit the ~/source/posting-api/config/production.json file to add the following (note the reference to the Hostname below refers to the internal ELB where the MongoDB EC2 instance should be added):

{
	"data": {
		"url": "mongodb://internal-stage-hashtagsell-data-154009749.us-west-2.elb.amazonaws.com:27017/hashtagsell-posting-v1"
	},
	"server": {
		"port": 8880,
		"secure": false
	}
}

Now copy the appropriate init scripts to the /etc folder:

sudo cp ~/source/posting-api/init/posting-api.conf /etc/init
sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.orig
sudo cp ~/source/posting-api/init/nginx.conf /etc/nginx/
