Install MongoDB and start Mongodb:
$ service mongodb start
Install Redis and start Redis. For all *nix systems, use these instructions. For Ubuntu, try this:
$ sudo apt-get install -y python-software-properties
$ sudo add-apt-repository -y ppa:rwky/redis
$ sudo apt-get update
$ sudo apt-get install -y redis-server
Install dependent Node.js modules based on package.json declaration
$ npm install <in-your-winecellar-home>
Follow the instructions on installing the AppDynamics Node.js Agent.
Be sure to have a 3.8+ controller and insert your variables into the necessary javascript in the head of your front controller.
require("appdynamics").profile({
controllerHostName: <controller host name>,
controllerPort: <controller port number>,
accountName: <AppDynamics account name>, //Required for a controller running in multi-tenant mode.
accountAccessKey: <AppDynamics account key>, //Required for a controller running in multi-tenant mode.
applicationName: <app_name>,
tierName: <tier_name>,
nodeName:<node_name>, //Prefix to the full node name.
debug: true //Debug is optional; defaults to false.
});For a single process
$ node server.js
For a 5 process cluster
$ node server-cluster.js
To keep your server up, run the aforementioned commands with "forever" instead:
$ forever start server.js
$ forever start server-cluster.js
You can view the Node.js server running via
$ forever list
Access http://[hostname]
Q: After going through all the install steps, I still cannot load the Wine Cellar website
A: Port 80 might be blocked. Try the following:
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sudo service iptables save
Q: I just opened up port 80 in the iptables, yet still no luck. I'm running on EC2.
A: Port 80 might still be blocked on EC2. You must go to your EC2 management console and assign a Security Group to your EC2 instance that has port 80 opened.
Q: When I tried to clone the repository, I received a fatal error "Could not read from remote repository".
A: You must generate an SSH key and add it to your Github account. See here for instructions on how. Make sure the key is associated with the user you are using - if you are root, create the key as root.
Q: When I try to run 'forever start server.js', I get the following error "/usr/bin/env: node: No such file or directory".
A: On Ubuntu, Node.js is invoked via 'nodejs'. A simple soft link will help:
$ ln -s /usr/bin/nodejs /usr/bin/node
Q: My hard drive is maxing out of space because of the logs generated by forever
A: Since console.log() writes to your standard output (stdout), one option is to configure forever to store the output of stdout in /dev/null:
$ forever -o /dev/null server.js
