Complete Guide to Install GitLab, Redmine (w. Backlogs), on a Plesk managed Debian server

Getting Started with the Server: Installation and SLL

The whole guide was tested for the fresh installation of Debian 7.8 Weezy managed by Plesk 12.

Grab your server, for example @ and get the OS installed:

Install Debian 7 with plesk 12For the szenario i have chosen for the installation, the GitLab will be installed on the main domain and you will need the ssl certificate to ensure clean so and i will call it „www.your.domain“. You could also make „gitlab.your.domain“, however you would need a wildcard certificate, which is a bit more expensive.

Grab the inclusive SSL certificate from 1blu and install it on your server. Dont forget to change the ip-adresses configuration and specify the freshly installed certificate on it.

Now you are ready to go.


Credits go to this guide:

The only part which differs is, that we are going to configure MySQL and Apache via Plesk. So copy paste it and check the original guide if you have got more questions:

Some troubleshooting

Internal error on redmine e.g. on „My Account“ page

If you are getting internal errors on redmine like

Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error.

Check that „www-data“ is being default user for installing and running redmine through passenger!

PassengerDefaultUser www-data

For further debuggind you will find the logs in /var/logs/apache2/

Another error: „repository in Redmine git 404“

chmod -R o=rx /home/git/repositories

chgrp www-data /home/myuser/folderA
chmod g+rwxs /home/myuser/folderA

If you are facing the following error after having done the step above:

(<unknown>): did not find expected key while parsing a block mapping at line 95 column 9
/usr/local/lib/ruby/2.1.0/psych.rb:370:in `parse'
/usr/local/lib/ruby/2.1.0/psych.rb:370:in `parse_stream'
/usr/local/lib/ruby/2.1.0/psych.rb:318:in `parse'
/usr/local/lib/ruby/2.1.0/psych.rb:245:in `load'

Get the new gitlab yaml and doublecheck that you have removed only 1 (ONE) symbol (dash) in the redmine setting. Yaml parser is extremely sensible

Installing Backlogs

So ok, now we have got gitlab and redmine: the last thing we require now to go is: backlogs!

Here is the official installation guide for backlogs

# let's go into redmine's plugin directory
cd /opt/redmine/current/plugins

# clone the repostitory:
git clone git://

cd redmine_backlogs

git tag

git checkout v1.0.6

#dont forget to set rails env to production, otherwise it will take the development
export RAILS_ENV

#now update some gems:
cd /opt/redmine/current/

#we should update nokogri to 1.6.5.:
# "bundl install" will be executed automatically so no more need to
bundle update nokogiri
bundle exec rake db:migrate
bundle exec rake tmp:cache:clear
bundle exec rake tmp:sessions:clear

Now preapre the trackers in the redmine: create a „Stories“ and a „Sasks“ tracker.  If you want you can modify the default one. And here we go:

# while being in the redmine directory:
bundle exec rake redmine:backlogs:install

# chose trackers in the installer and you are done!
#Installation complete. Please restart Redmine.
# Thank you for trying out Redmine Backlogs!

# make it safe: restart the whole server 

Congratulations – we are done!
