Installation on Amazon EC2
We've made an Amazon Machine Image (AMI) so you can quickly deploy on Amazon EC2. This is handy if you just want to evaluate Alaveteli, for example.
Note that there are other ways to install Alaveteli.
Installing from our AMI
To help you try out Alaveteli, we have created an AMI with a basic installation of Alaveteli, which you can use to create a running server on an Amazon EC2 instance. This creates an instance that runs as a development site. If you want to use this for a production site, you must change the configuration.
As Vagrant now seems to be the most popular way to try out Alaveteli, we are no longer updating the AMI with every release so the AMI is not guaranteed to include the latest version of Alaveteli. However, we will be happy to update the AMI on request, just get in touch!
What's in the AMI? The AMI gives you exactly the same thing as the installation script does. You get an Alaveteli website powered by Rails running the Thin application server under nginx, using a postgreSQL database. All this running on Amazon's EC2 servers, ready to be configured and customised.
Amazon instances are graded by size. Unfortunately, the Micro instance does not have enough memory for Alaveteli to run – and that’s the only size available on Amazon’s free usage tier. You need to use a Small instance or larger, which Amazon will charge you for.
Using Amazon web services
To do this, you’ll need:
- an account with Amazon
- a SSL key pair (the Amazon web service screens guide you through this)
If you don’t have these already, you’ll need to create them. See Amazon’s introduction on running a Virtual Server on AWS.
Launch the instance
Once you’re logged in to Amazon’s service, and navigated to the EC2
Management Console, you can launch the instance. If you prefer to do this
manually, you can find the AMI in the “EU West (Ireland)” region, with the ID
ami-d2c812a1 and name “Basic Alaveteli installation 2015-09-17”.
Alternatively, use this link:
When the instance launches, the first thing you need to choose is the instance type. Remember that the Micro type does not have enough memory to run Alaveteli, so you must choose at least Small or Medium – note that these are not available on Amazon’s free usage tier.
When the instance is created, the Amazon interface presents you with a lot of choices about its configuration. You can generally accept the defaults for everything, except the Security Groups. It’s safe to click on Review and Launch right away (rather than manually configuring all the instance details) because you still get an opportunity to configure the security groups. Click on Edit Security Groups on the summary page before you hit the big Launch button.
You must choose Security Groups that allow at least inbound HTTP, HTTPS, SSH and, if you want to test incoming mail as well, SMTP. Amazon’s settings here let you specify the IP address(es) from which your instance will accept requests. It’s good practice to restrict these (if in doubt, choose a Source of “My IP” for them all – except incoming HTTP: for that, simpy to set Source to “Anywhere”). You can change any of these settings later if you need to.
Log into the server (shell)
You need access to the server’s command line shell to control and configure your Alaveteli site.
To access the server, use
ssh and the
.pem file from your SSL key pair.
.pem file and instance ID to match your own in this command, which
connects to your server and logs you in as the user called
ubuntu. Issue this
command from your own machine, to log in to the server:
ssh -i path-to/your-key-pair.pem email@example.com
You won’t be asked for a password, because the
.pem file you supply with the
-i option contains the authorisation that matches the one at the other end,
on the server. You will be logged into the shell on your new Alaveteli server,
and can issue Unix commands to it.
Smoke test: start Alaveteli
You must configure your Alaveteli site, but if you just want to see that you’ve got your instance running OK, you can fire it up right away. Ideally, you should skip this step and go straight to the configuration… but we know most people like to see something in their browser first. ;-)
On the command line shell, as the
ubuntu user, start Alaveteli by doing:
sudo service alaveteli start
Find the “public DNS” URL of your EC2 instance from the AWS console, and look
at it in a browser. It will be of the form
http://your-ec2-hostname.eu-west-1.compute.amazonaws.com. You’ll see your
Alaveteli site there.
Your site isn’t configured yet, so this is insecure (for example, you haven’t set your own passwords for access to the administration yet), so once you’ve seen this running, bring the Alaveteli site down with:
sudo service alaveteli stop
When you log into your instance’s command line shell, you must do so as the
ubuntu user. This user can
sudo freely to run commands as root. However,
the code is actually owned by (and runs as) the
You will need to
customise the site’s configuration.
Do this by logging into your EC2 server and editing the
The configuration file you need to edit is
/var/www/alaveteli/alaveteli/config/general.yml. For example, use the
editor (as the
alaveteli user) like this:
ubuntu@ip-10-58-191-98:~$ sudo su - alaveteli alaveteli@ip-10-58-191-98:~$ cd alaveteli alaveteli@ip-10-58-191-98:~/alaveteli$ nano config/general.yml
After making changes to that file, you’ll need to start the application
restart rather than
start if it’s already running):
alaveteli@ip-10-58-191-98:~/alaveteli$ logout ubuntu@ip-10-58-191-98:~$ sudo service alaveteli start
Your site will be running at the public URL again, which is of the form
