Bitnami makes it easy to get started with Rails with their Amazon Machine Image (AMI) which creates a server for your app with all of the software you need already installed. For my apps, I’m using Apache and Passenger, but Nginx is also installed if you prefer that.
Here are some instructions for setting up Rails using Apache / Passenger / MySQL
(2) log in, and go to your AWS Management console
(3) go to the EC2 section
(4) click on the security groups link
(5) change the default security group to allow inbound requests:
http, https and ssh access from ip 0.0.0.0/0
(this allows people to access your app over http or https and allows you shell access to the server)
(6) click on the key pairs link and create a key pair (you’ll need this to access your EC2 instance)
(7) click the instances link
(8) click the ‘launch instance’ button and then select to create an instance from the Amazon Marketplace. In the search box, enter Ruby on Rails
(9) select the Bitnami Ruby on Rails image and then follow the steps to create the instance
(10) while your instance is getting created, you’ll want to create your MySQL database. In the Console, off the top menu, click “Services” and then RDS (under databases)
(11) click the “launch a DB instance” button in RDS, click MySQL on the next screen
(12) on the next screen, select a class (based on how powerful the server you want running your DB), enter the other required fields and record or remember what you entered here as you’ll need them to access your database
(13) Click on the “DB Security Groups” link. Click on the default group, and down below you should be able to alter the permissions. If you want to be able to access your database from your PC, add one for CIDR/IP and then copy the CIDR detected (it will show as AWS’s best guess in small font once your select CIDR). You will need to add one for “EC2 Security Group” and select the “Default” EC2 security group. This does not mean that you are adopting the settings of the EC2 security group – it means that you are allowing members of that group to access the DB – this way your EC2 server with the application can access the database.
(14) Next you’ll have to update your database.yml file to make sure it connects to your RDS. Once your instance has finished creating (green light next to the instance), click on the DB Instances tab on the left, and then on the next screen click on your instance. This should bring up the properties of the instance in the lower frame of the web page. Note the “endpoint” as this is the host you will use in your database.yml.
In your database.yml, for production enter this:
database: (your database name from step 12)
username: (your database user name from step 12)
password: (your database password from step 12)
host: (your endpoint)
(15)next you’ll want to log in to your EC2 instance, which should have been created by now to finish setting that up. to log in, you can use the Putty program or you can use the Java shell client that AWS provides. To use the the client AWS provides, go to Services > EC2 in the AWS management console. Click on the Instances tab, and then right click your running instance and select “connect”.
(16) In the Java pop-up, change the user name from ubuntu to bitnami, and change the private key path to the path that the .pem file you downloaded to (in step 6), and then click “Launch SSH instance”. If you are prompted to add the remote host, click ‘yes’.
(17) once you’re in, you can create a directory for your app, i put mine in /home/bitnami/apps/myappname
sudo mkdir myappname
(18) you can follow these steps to set-up git on your EC2 instance. For my EC2 instance, I put my repo in: /home/bitnami/repo (so you may want to change the directories in the set-up git link)
(19) we want to make sure your permissions are correct, otherwise your app will get 403 errors (Permission Denied) when accessing pages of your app. Go to the directory above the one where you put your app. For example, I used /home/bitnami/apps/myappname, so I would go to the /home/bitnami/apps folder:
sudo chown -R bitnami:bitnami myappname
chmod -R 775 myappname
chmod -R 755 myappname
(20) after you’ve pushed your code, it should be in the directory you set-up for your app (in my example, /home/bitnami/apps/myappname). run these three commands:
(21) with apache and passenger already installed, your app is ready to run. the one last thing you have to do is to point Apache to your app. to do that, go into your shell client and enter this command:
(22) you should now be editing the httpd.conf file which is apache’s configuration for routing. find this line and delete it:
(23) paste (shift + insert key) in this (replace “myappname” with your app’s name):
Allow from all
(24) exit and save (CNTL + x, then click enter when it asks you if you want to save)
(25) run these commands to stop and restart your server so the changes take effect:
sudo apachectl -k stop
sudo apachectl -k graceful
(26) go to the public IP for your EC2 instance (you can find this if you go into the AWS Management Console, then go to the EC2 section – Services > EC2 – and click on your running instance to see the attributes – it’s “Public DNS”)
You’re app should now be available on the web at this address.
