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.  
 Note: in some CentOS-like linux distros (RHEL, Amazon Linux) the C++ compiler does not come as part of the GCC compiler package. If that's the case, it can be installed with the following command: 
 <pre>yum install gcc-c++</pre> 

 <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>  
 or if You have a problem try  
 <pre>gem install bundler --verbose</pre> 

 * Error: /usr/local/bin/ruby: symbol lookup error: /usr/local/lib/ruby/site_ruby/1.8/x86_64-linux/zlib.so: undefined symbol: RB_GC_GUARD 
 <pre> 
 wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz [[http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz]] 
 tar xvzf ruby-zlib-0.6.0.tar.gz 
 cd ruby-zlib-0.6.0 
 ruby extconf.rb && make && make install 
 </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!*
