JIRA on a raspberry pi 2
Since the raspberry pi 2 comes with 1 GB RAM and a 900 MHz quad-core I wanted to give it a try
if it is capable of running JIRA

Download free trial linux .tar.gz archive from https://www.atlassian.com/software/jira/download?b=j

Untar with tar -zxvf <archive>

Check java version and set JAVA_HOME
Make sure that you have a java version installed that is supported by JIRA

In my case java 1.8 was installed, you can find this out by typing
java -version
Set JAVA_HOME by adding JAVA_HOME="/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/bin/" to /etc/environment
and adding export JAVA_HOME="/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/bin/" to your ~/.bashrc

Set the jira home directory
edit file <jira-application-dir>/atlassian-jira/WEB-INF/classes/jira-application.properties
I've set it to /usr/local/jira

Set JIRA_HOME environment variable
Add export JIRA_HOME="usr/local/jira" to your ~/.bashrc

Start jira by running <jira-application-dir>/bin/start-jira.sh

Troubleshooting:
1: logfile <jira-application-dir>/catalina.out told me that it could not find java.
"/home/sfuchs/jira/atlassian-jira-6.3.15-standalone/bin/catalina.sh: 1: eval: 
/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/bin//bin/java: not found"

Problem is that the command 'java' is already found in /usr/bin (which is set in PATH)
The 'java' at the end of the java path is replaced by '/bin/bash' (notice the two '//')
Since there is no <java-dir>/bin//bin/java it won't find the java executable
To solve this delete JAVA_HOME by typing export JAVA_HOME=""

2: After restarting jira and reloading <hostname>:8080 it told me "Could not create subdirectory 'caches' 
of jira.home '/usr/local/jira'."

Let's check permissions
Create a jira user by typing sudo adduser jira
Pass: secret
sudo chown -R jira logs/ temp/ work/ /usr/local/jira/
Switch over to new user and start jira
su jira
bin/start-jira.sh

---> Works: Now set up jira via the installer at <hostname>:8080

I used the built-in database for evaluation

Results: Yes, JIRA runs on a raspberry pi 2. Though it is rather slow and performance will likely
collapse if several users are logged in.
However If you are using JIRA alone or with just one or two colleagues the raspberry pi 2 may do the job.

Guide for Pi3, mostly based on the work of @idefux: https://github.com/jdavidpeter/Jira-on-Raspberry-Pi
It works fine for small projects, although doing search on hundreds of jiras takes several seconds.
