Contents

1. Demo Steps
2. Considerations
3. Ubuntu Packages
4. General Links
5. Azure Links

Demo Steps:

1. Create Virtual Machine in Azure Portal/Dashboard
2. Open ports: 22 (ssh), 80 (http), 9418 (git)
3. Write Node.js code locally (see file)
4. Create local git repo
5. git Add/Commit changes
6. Install git-core on server
   • sudo apt-get install git-core
7. Install node.js on server
   • sudo apt-get install build-essential
   • sudo apt-get install nodejs
   • sudo apt-get install npm
8. Setup git server
   • create git user account
     • sudo adduser git
   • setup .ssh/authorized_keys
     • copy your local ~/.ssh/id_rsa.pub to server's ~/.ssh/authorized_keys file
9. Create Upstart/init.d file
   • make exectuable e.g. sudo chmod +x /etc/init.d/appyHour
10. Hack Sudoers group
    • user ALL = NOPASSWD: ALL
11. Setup git hooks
    • pre-receive
    • post-receive
    • make executable e.g. chmod +x /home/raykao/git/appyhour.git/post-receive
12. Setup git remote server config on local machine
    • git remote add origin master git@servername.com:~/path/to/repo.git
13. Push local repo to server
    • git add .
    • git commit -m "initial commit"
    • git push origin master
14. Show server is running
    • Open browser to server url e.g. http://appyhour.cloudapp.net
15. Make Code Changes
16. Push changes to server
17. Show changes are live
18. Profit

Considerations

1. Install server firewall package (ufw - uncomplicated firewall)
2. Install and configure Nginx as server proxy
3. Make more secure - Sudoers hack is bad for business

Ubuntu Packages Used

1. git-core
2. nodejs

General Links

1. Deploy Node.js website with git
2. Hello Node - Node.js server examples
3. Git - Git Hooks

server.js

// Modified From: http://howtonode.org/hello-node

// Load the http module to create an http server.
var http = require('http');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.end("Hello World\n");
});

// Listen on port 80 (default http port), IP defaults to 127.0.0.1
server.listen(80);

// Put a friendly message on the terminal
console.log("Server running at http://127.0.0.1:80/");
