Redmine

h1. Redmine on CentOS installation HOWTO

{{>toc}}

This works with CentOS versions 5 and 6 and describes how to get Redmine 1.3.2 set up.

h2. 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

h1. Install pre-dependencies

<pre>yum -y install zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel</pre>

h2. Ruby

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

<pre>cd ~/Downloads  # YOUR FOLDER OF CHOICE

ftp ftp.ruby-lang.org

</pre>

h3. FTP session

<pre>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</pre>

h3. Untar

<pre>tar zxvf ruby-1.8.7.pXXX.tar.gz</pre>

h3. Install

<pre>cd ruby-1.8.7.pXXX

./configure

make

make install</pre>

h3. 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".

<pre>ruby -v</pre>

h3. Fix dependencies

(Only in case _ruby -v_ is *NOT* working)

<pre>which ruby  # TO CHECK WHERE IT SHOULD BE

whereis ruby  # TO CHECK WHERE IT IS INSTALLED</pre>

_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).

h4. Fix via adding /usr/local/bin to $PATH

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

<pre>nano /etc/profile</pre>

Make the section with _pathmunge_ look alike like this:

<pre>#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</pre>

OR ADD THIS AT THE END OF THE FILE:

<pre>nano /etc/profile

export PATH="$PATH:/usr/local/bin"</pre>

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

<pre>nano ~/.bashrc

export PATH="$PATH:/usr/local/bin"</pre>

h4. 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

<pre>ln -s /usr/local/bin/ruby /usr/bin/ruby</pre>

h4. Verify ruby to be working

<pre>ruby -v # NOW IT MUST RETURN RUBY VERSION, ELSE SOMETHING ELSE IS BROKEN

cd ..</pre>

h2. RubyGems 1.4.2 

*Does not work with Gems 1.5!*

h3. Download

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

h3. Untar

<pre>tar zxvf rubygems-1.4.2.tgz</pre>

h3. Setup

<pre>cd rubygems-1.4.2

ruby setup.rb</pre>

h3. Check installation

<pre>gem -v</pre>

h3. In case this does not work...

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

h2. Passenger

h3. Regular install method

Requires gcc.

<pre>gem install passenger

passenger-install-apache2-module</pre>

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!

h3. Alternative install method 

Install mod_passenger RPM for Apache from the following location:

> http://passenger.stealthymonkeys.com/

_RHEL/CentOS 5_

<pre>rpm -Uvh http://passenger.stealthymonkeys.com/rhel/5/passenger-release.noarch.rpm

yum install mod_passenger</pre>

_RHEL/CentOS 6_

<pre>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</pre>

h2. Restart Apache

<pre>service httpd restart</pre>

h1. Install Redmine

h3. Download

Download page: 

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

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

h3. Untar

<pre>tar zxvf redmine-1.3.2.tar.gz</pre>

h3. Copy the folder to its HTTP document root folder

<pre>mkdir /var/www/redmine

cp -av redmine-1.3.2/* /var/www/redmine</pre>

h1. Link Redmine to the Database

h2. Install MySQL DB Server

<pre>yum install mysql-server

chkconfig mysqld on

service mysqld start

/usr/bin/mysql_secure_installation</pre>

h2. Create a MySQL database to use with Redmine

h3. Latest MySQL Version

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

> > <pre>create database redmine character set utf8;

create user 'redmine'@'localhost' identified by 'my_password';

grant all privileges on redmine.* to 'redmine'@'localhost'; </pre>

h3. For versions of MySQL prior to 5.0.2

> Skip the 'create user' step and do instead:

> >  <pre> grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';</pre>

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.

h2. Configure /var/www/redmine/config/database.yml 

<pre>cp database.yml.example database.yml</pre>

TODO: describe what to change there...

h1. Rails Settings

h2. Dependency management with bundler

For more info go to the "bundler site":http://gembundler.com/.

h3. Install

<pre>gem install bundler</pre>

h3. Create Gemfile

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

<pre>nano /var/www/redmine/Gemfile</pre>

h3. Register gems

Put the following into the file you just opened:

<pre># 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"</pre>

Save and exit the editor.

h3. Install the provided dependencies:

<pre>cd /var/www/redmine

bundle install</pre>

h2. 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:

<pre>ENV['RAILS_ENV'] ||= 'production'</pre>

h2. Generate the session store

<pre>RAILS_ENV=production bundle exec rake generate_session_store</pre>

h2. Migrate the database models

<pre>RAILS_ENV=production bundle exec rake db:migrate</pre>

h2. Load default data (optional)

<pre>RAILS_ENV=production bundle exec rake redmine:load_default_data</pre>

Follow instructions.

h2. Rename dispatch CGI files in /var/www/redmine/public/

<pre>

mv dispatch.cgi.example dispatch.cgi

mv dispatch.fcgi.example dispatch.fcgi

mv dispatch.rb.example dispatch.rb

</pre>

h1. Apache Settings

h2. Configure Apache to host the documents

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

h2. Edit .htaccess file for CGI dispatch configuration

<pre>

mv htaccess.fcgi.example .htaccess

</pre>

h2. Fix rights for the apache user

<pre>

cd ..

chown -R apache:apache redmine-1.x

chmod -R 755 redmine-1.x

</pre>

This should be everything.

*Redmine is now installed and usable.*

*Enjoy!*
