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

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

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. 

<pre>ruby -v</pre>

If it works, skip directly to "RubyGems 1.4.2".

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. For this setup you want to change the PATH for root, too:

<pre>nano ~/.bashrc

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

Logout your user and login again, to make the changes work.

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 create symlinks for them later on, too.

Symlinks are created like this

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

h4. Verify ruby to be working

<pre>which ruby  # MUST RETURN PATH TO RUBY

ruby -v  # MUST RETURN RUBY VERSION

cd ..</pre>

Now it has to work. When changing $PATH variable, did you log out and log on again with your current user?

If this does not function properly, other things later on will also not work.

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. Do things work?

... else the cause is the same as with the ruby problem before...

h2. Passenger

h3. Regular install method

Requires C++ compiler to complete.

If it cannot be found in the system, the commands how to install it will be shown later on.

<pre>gem install passenger

passenger-install-apache2-module</pre>

The install process is interactive and you wil be told what to do. How to install missing dependencies is described exactly. JUST 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

Start the mysql client:

<pre>mysql -u root -p</pre>

The version you have is shown in the welcome message.

Enter the following commands in the mysql console: (without repeating the prompt ;) )

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

h3. Latest MySQL Version

<pre>mysql> create user 'redmine'@'localhost' identified by 'my_password';

mysql> grant all privileges on redmine.* to 'redmine'@'localhost';

mysql> \q</pre>

h3. For versions of MySQL prior to 5.0.2

Skip the 'create user' step and do instead:

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

mysql> \q</pre>

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

h2. Configure database.yml 

There you have to enter the user:password combination (redmine:my_password) in the config file, so Redmine can actually talk to the database (redmine).

<pre>cd /var/www/redmine/config

cp database.yml.example database.yml

nano database.yml</pre>

Change it to look like:

<pre>production:

    adapter: mysql

    database: redmine

    host: localhost

    username: redmine

    password: my_password

    encoding: utf8</pre>

The other entries are not important, since we will use only the production environment. But if you would need the development or test environment, don't forget the create additional databases. *Don't* use the same database for production and testing or development environment!

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

<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.

<pre>nano /var/www/redmine/config/environment.rb</pre>

Uncomment the following line at top of the file:

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

h2. Generate the session store

(In the terminal again...)

<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 /redmine/public/

<pre>cd /var/www/redmine/public

cp dispatch.cgi.example dispatch.cgi

cp dispatch.fcgi.example dispatch.fcgi

cp 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>cd /var/www/redmine/public

cp htaccess.fcgi.example .htaccess</pre>

h2. Fix rights for the apache user

<pre>

cd /var/www

chown -R apache:apache redmine

chmod -R 755 redmine

</pre>

This should be everything.

*Redmine is now installed and usable.*

*Enjoy!*
