Installing Confluence on a EC2 t2.micro Free Tier Instance

Requirements

Being Confluence a java application at least 6 gb of ram are recomended, you can get away by using 1 core, but using the 1 GB of RAM included with the free tier t2.micro might really slow down the instance, but it will slow down the response times of the instance, with this out of the way, let us begin

Create the instance

Create an AWS account at http://aws.amazon.com/
Launch the AWS EC2 Management Console at https://console.aws.amazon.com/ec2/v2/home
Click on Instances
Click on Launch Instance
Click on Select for the Amazon Linux AMI SSD Volume Type (Select 64-bit (x86) Amazon Linux AMI 2018.03.0 (HVM), SSD Volume Type - ami-01e24be29428c15b2)
On the Instance Type screen, select the t2.micro type and click Next: Configure Instance Details

Security Groups

Create a new security group Called "Confluence" by adding the necessary rules:

Type	Protocol	Port Range	Source
HTTP	TCP	80	0.0.0.0/0
HTTPS	TCP	443	0.0.0.0/0
SSH	TCP	22	0.0.0.0/0
Custom TCP Rule	TCP	8005	0.0.0.0/0
Custom TCP Rule	TCP	8090	0.0.0.0/0
Custom TCP Rule	TCP	8443	0.0.0.0/0

Launch EC2 instance

Click the Launch button
Create a new key pair named ec2-confluence
Download the key pair file ec2-confluence.pem and save it somewhere secure
Click Launch Instance
Click View Instances
Select the newly created instance and grab it's Public IP

Connect to and setup your EC2 instance

From a terminal, ssh in to your machine using the command:

ssh -i /path/to/ec2-confluence.pem ubuntu@<IP ADDRESS>

User = ec2-user

Run sudo yum update after your initial login, and update the software
Create a swap file:

[ec2-user@ip ~]$ sudo dd if=/dev/zero of=/var/swapfile bs=1M count=2048
[ec2-user@ip ~]$ sudo chmod 600 /var/swapfile
[ec2-user@ip ~]$ sudo mkswap /var/swapfile
[ec2-user@ip ~]$ echo /var/swapfile none swap defaults 0 0 | sudo tee -a /etc/fstab
[ec2-user@ip ~]$ sudo swapon -a

Reboot the EC2 instance to ensure the swap is in use:

[ec2-user@ip ~] sudo reboot now

Reconnect to the machine via ssh using the command from step 12. The instance may not be immediately available as it reboots.

Download and install Confluence

During this tutorial, the latest version of Confluence is 6.13.0 and is available at https://www.atlassian.com/software/confluence/downloads/binary/atlassian-confluence-6.13.0-x64.bin. To find the URL for the latest version of Confluence, see the download page at https://www.atlassian.com/software/confluence/download, select Linux, and copy the Trial download destination link for the 64bit installer.

Download Confluence to a downloads directory, and execute the installer

[ec2-user@ip ~]$ mkdir downloads; cd downloads
[ec2-user@ip ~]$ wget -O confluence.bin https://www.atlassian.com/software/confluence/downloads/binary/atlassian-confluence-6.13.0-x64.bin
[ec2-user@ip ~]$ chmod u+x confluence.bin
[ec2-user@ip ~]$ sudo ./confluence.bin

Run through the Confluence setup wizard, default/express install is fine
Add the hostname to the hosts file so Confluence can reliably configure the local database, followed by a last reboot of the machine

[ec2-user@ip ~]$ cd /etc
[ec2-user@ip ~]$ sudo nano hosts

1. Add the variable $HOSTNAME to the file

[ec2-user@ip ~]$ sudo reboot now

Once the machine has rebooted, you will be able to start configuring Confluence via the web based setup wizard by via the IPv4 address on the AWS Consoles using http://<IP ADDRESS>:8090/.

The intial setup of Confluence can take a long time - this process can take well over 10 minutes. Be patient and allow it to complete loading.

Notes

If you are connecting Confluence for using Jira authentication; you will need to configure the User Group to use jira-software-users since jira-users does not exist by default.
