Red­mi­ne ist wohl eines der kom­for­ta­bels­ten und mäch­tigs­ten Issue-Track­ing-Sys­te­me im Open-Source-Bereich.
Hier möch­te ich zei­gen, wie man es auf einem Debi­an-Ser­ver mit nginx als Web­ser­ver instal­liert und einrichtet:

Mit Red­mi­ne 3.0.0 muss das "Red­mi­ne Boot­strap Kit plug­in" v0.2.0 und das "Red­mi­ne Git Hos­ting Plug­in" v1.0.1 oder höher ver­wen­det werden.
Hier­zu sind gege­be­nen­falls Anpas­sun­gen an den Depen­den­ci­es der Gem­files nötig, wel­che sich aus den Hin­wei­sen der Bund­ler-Instal­la­ti­ons­pro­ze­du­ren ergeben.

Tipp:
https://github.com/jbox-web/grack.git klonen und in plugins/redmine_git_hosting/Gemfile ändern: "gem 'gitlab-grack', path: '/opt/redmine/plugins/redmine_git_hosting/grack', require: 'grack'"
In plugins/redmine_git_hosting/grack/grack.gemspec "gem.add_dependency("rack", "~> 1.4.1")" auskommentieren.
In plugins/redmine_git_hosting/Gemfile "gem 'redcarpet', '~> 2.3.0'" auskommentieren.
