h1. Redmine on CentOS installation HOWTO 


 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 

 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 
 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 
     pathmunge /usr/local/bin after    # ADDED THIS 
     pathmunge /usr/local/sbin after 
     pathmunge /usr/sbin after 
     pathmunge /sbin 


 <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 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>which ruby    # MUST RETURN PATH TO RUBY 
 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 


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

 <pre>gem install passenger 

 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: 


 _RHEL/CentOS 5_ 
 <pre>rpm -Uvh 
 yum install mod_passenger</pre> 

 _RHEL/CentOS 6_ 
 <pre>rpm --import 
 yum install 
 yum install mod_passenger</pre> 

 h2. Restart Apache 

 <pre>service httpd restart</pre> 

 h1. Install Redmine 

 h3. Download 

 Download page:  


 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 

 h2. Create a MySQL database to use with Redmine 

 h3. Latest MySQL Version 

 Start > start the mysql client (@mysql -u root -p@), -p@) and enter the version you have is shown in the welcome message. 
 Enter the following commands: 
 > > <pre>create database redmine character set utf8;</pre> 

 h3. Latest MySQL Version 

 <pre>create utf8; 
 create user 'redmine'@'localhost' identified by 'my_password'; 
 grant all privileges on redmine.* to 'redmine'@'localhost'; 


 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'; 
 \q</pre> 'my_password';</pre> 

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

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

 <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": 

 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 "" 
 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/ 

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

 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 

 mv htaccess.fcgi.example .htaccess 

 h2. 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.*
