howToInstallRedmineCentos

# Prepare the centos installing these packages:
yum install make gcc gcc-c++

# Install gem and passenger dependencies:
yum -y install zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel

# Go to ftp.ruby-lang.org and make the download of ruby, in this case: ruby-2.0.0-p247.tar.gz
# After download you have to untar it
tar zxvf ruby-2.0.0-p247.tar.gz

# Compile ruby
cd ruby-2.0.0-p247
./configure
make
make install

# Now you can verify if your ruby instalation was made successfully typing this on console:
ruby -v

# Since ruby version 1.9 comes with rubygem, so, there's no need to install it manually.

# Let's install passenger:
gem install passenger
passenger-install-apache2-module

# Go to http://rubyforge.org/projects/redmine/ and download the last version of redmine, in this case: redmine-2.4.0.tar.gz

# Go to Download directory and untar the redmine file:
tar zxvf redmine-2.4.0.tar.gz

# Lets move the redmine after untar to: /var/www/redmine
mv redmine-2.4.0 /var/www/redmine

# Lets install bundle ruby gem
gem install bundle

# Now ensure that the user and group of this directory and files is apache
chown -R apache.apache /var/www/redmine

# Now lets install redmine dependencies
cd /var/www/redmine
bundle install --without postgresql sqlite test development

# If there's any problem, install the libs requireds
yum install ImageMagick-devel
gem install rmagick -v '2.13.2'

# And then repeat the redmine dependencies installation
bundle install --without postgresql sqlite test development

# Now lets install Mysql server
yum install mysql-server

# Now lets start and configure Mysql
service mysqld start
mysql_secure_installation

# Now connect to mysql
mysql -u root
mysql> create database redmine character set utf8;
mysqk> grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';
mysql> flush privileges;
mysql> quit;

# Now lets configure redmine database
cd /var/www/redmine/config
copy database.yml.example database.yml

# Now open database.yml and put the root password on production section
gedit database.yml

# Now lets populate the redmine database
cd /var/www/redmine
rake generate_secret_token

# Maybe you need to run bundle install again if there's any dependence missing
bundle install

# Lets continue with redmine database population
rake db:migrate RAILS_ENV="production"
rake redmine:load_default_data RAILS_ENV="production"

# Our instalation is almost done, lets start redmine in standalone mode to test the instalation
cd /var/www/redmine
ruby script/rails server webrick -e production

# At this point you might access localhost:3000 and see redmine index page, if you don't go back and review your instalation.


# Now lets make the Apache configuration
cd /etc/httpd

# Lets remove the conf.d directory and recreate it with a custom content
mv conf.d available
mkdir conf.d

# Lets create an empty file inside conf.d called redmine.conf
gedit conf.d/redmine.conf

# Now put in the file the following content
LoadModule passenger_module /usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.24/buildout/apache2/mod_passenger.so
PassengerRoot /usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.24
PassengerDefaultRuby /usr/local/bin/ruby

<VirtualHost *:80>
   ServerName mycentos
   DocumentRoot /var/www/redmine/public
   <Directory /var/www/redmine/public>
      AllowOverride all
      Options -MultiViews
      allow from all
   </Directory>

   ErrorLog "|/usr/sbin/rotatelogs /etc/httpd/logs/redmine-error.%Y-%m-%d.log 86400"
   CustomLog "|/usr/sbin/rotatelogs /etc/httpd/logs/redmine-access.%Y-%m-%d.log 86400" "%h %l %u %t %D \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""
</VirtualHost>

# Now edit Apache configuration file and uncomenting this configuration:
gedit /etc/httpd/conf/httpd.conf

NameVirtualHost *:80

# Now test the Apache configuration
service httpd configtest

# At this point, the SELinux configuration needs to be modified to allow our apache instance to run the phusion passenger module. You can do this by putting SELinux in permissive mode
# Edit this file: /etc/selinux/config and change the follow configuration:
gedit /etc/selinux/config

# Change this setting
SELINUX=enforcing

# To this one:
SELINUX=permissive

# At this point our task is done, but we need to configure the services to start on machine start up
chkconfig --level 345 mysqld on
chkconfig --level 345 httpd on

# Finally restart your pc and enjoy
reboot
