JATOS on AWS

This page provides additional information on how to install JATOS on an AWS server. General installation advice can be found in JATOS on a server and applies here as well. We recommend using JATOS together with a reverse proxy. See our instructions for Apache or Nginx. If you are looking for an easier way to install JATOS in the cloud, check out the tutorial JATOS on DigitalOcean.

Register at AWS (a credit card is required).
In the AWS web console, go to EC2 and launch a new instance with Ubuntu (other Linux distributions are also possible).
During the creation of the EC2 instance, you will be asked to create a key pair. Do so and download the key file (a .pem file). Store it in a safe place—this key is required to access your server.
Log in via SSH:
```
ssh -i /path/to/your/pem_key_file ubuntu@<your-public-ip>
```
Use your instance's public IP address (found in AWS EC2 > Instances > Description).

Download the latest JATOS release:

With bundled Java:

wget https://github.com/JATOS/JATOS/releases/latest/download/jatos_linux_java.zip

Without Java (you must install Java yourself):

wget https://github.com/JATOS/JATOS/releases/latest/download/jatos.zip

Unzip the downloaded file:
```
unzip jatos_linux_java.zip
```
(If unzip is not installed, run sudo apt-get install unzip.)
If you do not use a reverse proxy like Nginx or Apache, configure the IP and port in conf/jatos.conf (or conf/production.conf for versions < 3.8.3):
- Use the Private IP (starts with 172.x.x.x) and port 80.
Allow inbound HTTP/HTTPS traffic: See this AWS guide.
(Optional) Set up JATOS to auto-start.
Change the JATOS admin password.
