An Angular App. Used AWS, EMR, HBase, mongodb, redis, cassandra, docker to developed a website with posting/login/authentication/relationship analysis function.

Clone the social-website repository using git:

git clone https://github.com/lys0716/social-website.git
cd social-website

Development is based on angular-seed. It has preconfigured npm to automatically run bower so we can simply do:

npm install

Please choose the angular version match angular-sanitize

We also use virtualenv to manage the python dependencies

cd util
virtualenv env
source 
pip install --upgrade -r requirement.txt
source env/bin/activate

PRESS esc -> INPUT :wq -> ENTER(quit the editor)

sudo yum install -y mongodb-org

vim /etc/mongod.conf

comment the bind ip configuration

sudo service mongod start

4. create database and table: use gallery db.products.insertMany([ { name: 'Introduction to Computer Science', price: 19, pubdate: new Date("2016-05-18"), cover: 'http://www.freeimages.com/assets/183333/1833326510/wood-weel-1444183-m.jpg', likes: 0, dislikes: 0 }, { name: 'Introduction to Data Science', price: 8, pubdate: new Date("2013-08-01"), cover: 'http://www.freeimages.com/assets/183333/1833326510/wood-weel-1444183-m.jpg', likes: 0, dislikes: 0 }, { name: 'Introduction to Big Data', price: 20, pubdate: new Date("2016-10-16"), cover: 'http://www.freeimages.com/assets/183333/1833326510/wood-weel-1444183-m.jpg', likes: 0, dislikes: 0 }, { name: 'Introduction to Bit', price: 4, pubdate: new Date("2015-01-01"), cover: 'http://www.freeimages.com/assets/183333/1833326510/wood-weel-1444183-m.jpg', likes: 0, dislikes: 0 } ])
