Redmine on CentOS installation HOWTO

This works with CentOS versions 5 and 6 and describes how to get Redmine 1.32 set up.

Assumptions

  • Apache is up and running
  • Apache has previously been used and works quite well
  • MySQL is up and running
  • MySQL has previously been used and works quite well
  • Your are logged as root
  • The next steps are done successively without errors

Install pre-dependencies

yum -y install zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel

Ruby

Things after *#* are comments, and it is no use to type this stuff in ;)

cd ~/Downloads  # YOUR FOLDER OF CHOICE
ftp ftp.ruby-lang.org

FTP session

ftp> Anonymous  # USERLOGIN
ftp> 'none', just hit Enter  # NO PASSWORD
ftp> cd /pub/ruby
ftp> get ruby-1.8.7.pXXX.tar.gz  # XXX is currently 358, as of 03/2012
ftp> bye

Untar

tar zxvf ruby-1.8.7.pXXX.tar.gz

Install

cd ruby-1.8.7.pXXX
./configure
make
make install

Check installation

If this does not work, it is probably because there is no ruby at /usr/bin to be found.
If it works, skip directly to "Get Gems 1.4.2".

ruby -v

Fix dependencies with a symlink

(Only in case ruby -v is NOT working)

which ruby  # TO CHECK WHERE IT SHOULD BE
whereis ruby  # TO CHECK WHERE IT IS INSTALLED

which returns like /usr/bin/ along with other directories (where ruby is expected to be), and whereis returns like /usr/local/bin/ruby (thats where ruby actually lies).

Create the Link:

ln -s /usr/local/bin/ruby /usr/bin/ruby

Check again if it is working:
ruby -v # NOW IT MUST RETURN RUBY VERSION, ELSE SOMETHING ELSE IS BROKEN
cd ..

RubyGems 1.4.2

Does not work with Gems 1.5!

Download

wget http://production.cf.rubygems.org/rubygems/rubygems-1.4.2.tgz

Untar

tar zxvf rubygems-1.4.2.tgz

Setup

cd rubygems-1.4.2
ruby setup.rb

Check installation

gem -v

In case this does not work...

... the solution is again creating a symlink, analogical like described in the ruby section above.

Passenger

Regular install method

Requires gcc.

gem install passenger
passenger-install-apache2-module

If the second line does not work, do whereis passenger to find out where it is installed.
So you can execute it like /usr/local/bin/passenger-install-apache2-module ...

The install process is interactive and you wil be told what to do. READ!

Alternative install method

Install mod_passenger RPM for Apache from the following location:

http://passenger.stealthymonkeys.com/

RHEL/CentOS 5

rpm -Uvh http://passenger.stealthymonkeys.com/rhel/5/passenger-release.noarch.rpm
yum install mod_passenger

RHEL/CentOS 6

rpm --import http://passenger.stealthymonkeys.com/RPM-GPG-KEY-stealthymonkeys.asc
yum install http://passenger.stealthymonkeys.com/rhel/6/passenger-release.noarch.rpm
yum install mod_passenger

Restart Apache

service httpd restart

Install Redmine

Download

Download page:

http://rubyforge.org/frs/?group_id=1850

wget http://rubyforge.org/frs/download.php/75910/redmine-1.3.2.tar.gz # GET LATEST VERSION ON RUBYFORGE

Untar

tar zxvf redmine-1.3.2.tar.gz

Copy the folder to its HTTP document root folder

mkdir /var/www/redmine
cp -av redmine-1.3.2/* /var/www/redmine

Configure Apache to host the documents

more information can be found here: HowTo configure Apache to run Redmine

Link Redmine to the Database

Install MySQL DB Server

yum install mysql-server
chkconfig mysqld on
service mysqld start
/usr/bin/mysql_secure_installation

Create a MySQL database to use with Redmine

Latest MySQL Version

start the mysql client (mysql -u root -p) and enter the following commands:

create database redmine character set utf8;
create user 'redmine'@'localhost' identified by 'my_password';
grant all privileges on redmine.* to 'redmine'@'localhost'; 

For versions of MySQL prior to 5.0.2

Skip the 'create user' step and do instead:

 grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';

Now the database is created and a user to be used with it. Also the user has the rights to work on the database that was created.

Configure /var/www/redmine/config/database.yml

cp database.yml.example database.yml

todo: describe what to change there...

Rails Settings

Dependency management with bundler

For more info go to the bundler site.

Install

gem install bundler

Create Gemfile

You can of course use vi/vim as your editor of choice, if you know what you are doing. ;)

nano /var/www/redmine/Gemfile

Register gems

Put the following into the file you just opened:

# file: /var/www/redmine/Gemfile
source "http://rubygems.org" 
gem "rake", "0.8.3" 
gem "rack", "1.1.0" 
gem "i18n", "0.4.2" 
gem "rubytree", "0.5.2", :require => "tree" 
gem "RedCloth", "~>4.2.3", :require => "redcloth" # for CodeRay
gem "mysql" 
gem "coderay", "~>0.9.7"

Save and exit the editor.

Install the provided dependencies:

bundle install

OPTIONAL: Set the production environment

Uncomment the following line in file redmine/config/environment.rb:

ENV['RAILS_ENV'] ||= 'production'

Generate the session store

RAILS_ENV=production bundle exec rake generate_session_store

Migrate the database models

RAILS_ENV=production bundle exec rake db:migrate

Load default data (optional)

RAILS_ENV=production bundle exec rake redmine:load_default_data

Follow instructions.

Rename dispatch CGI files in /var/www/redmine/public/

mv dispatch.cgi.example dispatch.cgi
mv dispatch.fcgi.example dispatch.fcgi
mv dispatch.rb.example dispatch.rb

Apache Settings

Edit .htaccess file for CGI dispatch configuration

mv htaccess.fcgi.example .htaccess

Fix rights for the apache user

cd ..
chown -R apache:apache redmine-1.x
chmod -R 755 redmine-1.x

This should be everything.
Redmine is now installed and usable.

Enjoy!
