This works with CentOS versions 5 and 6 and describes how to get Redmine 1.3.2 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¶

(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).

Fix via adding /usr/local/bin to $PATH¶

(Do this with your editor of choice, if you do not like nano.)

nano /etc/profile

Make the section with pathmunge look alike like this:

#Path manupulation
if [ "$EUID" = "0" ]; then
    pathmunge /sbin
    pathmunge /usr/sbin
    pathmunge /usr/local/sbin
    pathmunge /usr/local/bin  # ADDED THIS
else
    pathmunge /usr/local/bin after  # ADDED THIS
    pathmunge /usr/local/sbin after
    pathmunge /usr/sbin after
    pathmunge /sbin
fi

OR ADD THIS AT THE END OF THE FILE:

nano /etc/profile
export PATH="$PATH:/usr/local/bin"

This sets the PATH for all Users beside root. In case you want it for root to change, too:

nano ~/.bashrc
export PATH="$PATH:/usr/local/bin"

Fix via Symlink Creation¶

This is not recommended, since if the ruby dependency is broken, others will likely be later on, too. Repair this by adding the folder to the $PATH variable like described before, else gem, rake, bundle, passenger-install-apache2-module will not work either... you would have to creat symlinks for them, too.
Symlinks are created like this

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

Verify ruby to be 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:¶

cd /var/www/redmine
bundle install

Set environment to "production"¶

Rails has the concept of environments to represent the stages of an application’s lifecycle: test, development, and production by default.
Specify your choice with the RAILS_ENV environment variable.
Production has less verbose logging and is a bit faster, testing and development environment are not needed anyway for your Redmine.

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!
