Preparing rails environments for installing Redmine using RVM

For many rails applications to work correctly, specific versions of components are required, such as the ruby ​​version, the rails version itself, as well as rake, rubygems, etc. And most likely in your Linux distribution (in my case it is Ubuntu 10.04 LTS Server), the versions of these components will be different. You can go a simple way - put the required version of ruby ​​from the source code, and everything else with the help of rubygems. But we want to get a reliable and reproducible result, and the system, while not turning into a landfill.

To solve this problem, we use RVM (Ruby Version Manager). The following script (redmine-1.2-prepare.sh) prepares a rails environment for installing Redmine version 1.2 with a database in sqlite format. Apache2 + passenger is used as a web server. The script creates the redmine user, installs the necessary packages, installs the RVM into the home directory of the redmine user, and then rails the environment.

Following the script is an example of a configuration file for apache2 (redmine.conf) proposed by RVM itself at the end of the installation (I only added PassengerUser www-data from myself, since the default is nobody).

PS: The script provides the ability to install using a proxy server. The proxy must be installed via the http_proxy and https_proxy environment variables.

Script verified in Ubuntu 10.04 LTS Server

UPDATE : I don’t know whether you have already tried this script or not, but I found one mistake in it that was made during the “code painting”, I apologize. In line
"[[-s" $ HOME / .rvm / scripts / rvm "]] && source" $ HOME / .rvm / scripts / rvm "&& \"
there must be two more backslashes
"[[-s" \ $ HOME / .rvm / scripts / rvm "]] && source" \ $ HOME / .rvm / scripts / rvm "" && \ ".

UPDATE2 : starting with Redmine 1.4.x, the script can be somewhat simplified, because Redmine began to use the bundler to manage dependencies.

UPDATE3 : The latest versions of scripts are always on the link: http://www.helplinux.ru/wiki/en:kb:redmine-installation
