(UPDATE: I needed Redmine >=3.0 for a plugin, so I ended up re-doing this for version 3 of Redmine, which is a more complicated process. I wrote instructions for Redmine version 3 onto the Raspberry Pi 2, but they’re not quite as detailed as the ones here. But if you’re able to follow these instructions, you should be able to follow along for 3.0. It’s just a bit more complex because you have to build packages.)
(COMMENTS: I suggest you take a look below at the comments to this post if you run into anything unexpected, like an error. There is a lot of feedback for various issues some folks ran into.)
After scouring the internet, I’ve created the go-to tutorial for installing Redmine onto the Raspberry Pi 2 without assuming you are a Linux guru and without pages and pages of steps. This assumes you have a Raspberry Pi 2 and a freshly imaged SD card that has never booted. If you’ve already booted, that’s fine, you should be able to pick up around step 12 (I would recommend an SD image backup first!).
I’m using Raspbian 2015-02-16 in this tutorial. Yes, this is 27 steps, but it holds your hand and it zips by. Plus, the first half is initial Pi setup and backup.
- Before even booting your Pi, download Adafruit Pi Finder. This is a cross-platform utility that allows you to get started with your Pi without having to hook it to a TV and use a keyboard. It will discover it, tell you the IP, and get you connected without any display or keyboard attached to the Pi. Just make sure it’s connected via wire to your network.
- I suggest you image your SD card with Win32DiskImager.
- Insert your SD card, plug in the wired ethernet cable, and finally plug in the power supply. Let it go to town booting and doing it’s first time thing. Note that you don’t need it hooked to a screen or keyboard, you just need to let it run for a minute or two until the activity light dies down.
- Open PiBootstrap.exe.
- Click Find my Pi
- It will take a minute or two to search your network–be patient.
- If you have more than one Pi, you will need to make sure you edit the correct one, but I expect in most cases you will just have the one. Enter the SSH credentials you want to use and a hostname. I chose piredmine for my hostname. For this install, leave “Install the WebIDE?” unchecked.
- Click “Bootstrap!”
- The tool will connect, an SSH Terminal window will open, and go to town downloading and installing stuff. Let it run.
sudo raspi-configand expand the filesystem to fill the SD card.
- Optional: Shutdown, eject your SD card from the Pi, and make a backup on your regular machine using the same Win32DiskImager utility. This way, if things go wrong, you can rollback to this point easily. Put it back in your Pi when it’s done.
- Now to actually install stuff!
- (At this point, it may be easier to sudo su to become root rather than prefix all your commands with sudo. It’s up to you, though!)
sudo apt-get install apache2 mysql-serverand wait. You’ll be prompted to enter a password for the MySQL root user. Remember to make it secure. Wait some more.
- Next execute
sudo apt-get install redmine redmine-mysqland wait. You’ll be prompted about configuring the redmine/instances/default package with a lengthy text blurb advising you to select Yes. Select Yes, then select mysql. Now enter the MySQL root user password from earlier. For the next password prompt, you can leave it blank for a random password or enter whatever you like. This one shouldn’t ever be important for you to know because you know the root password. I left mine blank for random.
- You’ll see a message that “This may take awhile.” It is not kidding. Go do something else for 5 or 10 minutes.
It will give you false hope that it is done, but it’s not. Keep waiting.
- Finally it’s done, and we are nearly so. Execute one last install:
sudo apt-get install libapache2-mod-passengerThis one will be quick. A little configuration and we’ll be good to go.
sudo ln -s /usr/share/redmine/public /var/www/redmineThis will make your URL “http://youservername/redmine”
sudo chown -R www-data:www-data /var/www/redmine
sudo su(need to become root for this next one)
echo "RailsBaseURI /redmine" > /etc/apache2/sites-available/redmine.conf[Thanks Daniel]
exit(to exit root)
sudo a2ensite redmine
sudo /etc/init.d/apache2 reload
sudo /etc/init.d/apache2 restart
- Done! Surf to http://piredmine.local/redmine and wait for the initial loading process (this is a one-time wait). The default Redmine login is admin / admin
- You may need to make additional changes to your apache configuration if you’re running on a domain name, or to use plugins, but this was the hard part. Pat yourself on the back and eat some chocolate.
