The System Requirements

During the installation process we will use the Centos 6.5 – 64 bit OS, the original hardware configuration should not require high you can on a normal PC or a virtual machine using VMWare, VirtualBox.

For the CentOS operating system, you can downloading at URL address :

Download Centos

Selecting a 64-bit version called “CentOS-6.5-x86_64-bin-DVD1.iso”, after you download and install on the computer or on a virtual machine, the installation process is simple for anyone with basic computer skills.

Although this guiding document install on the Centos 6.5 operating system, but you can use any version of Centos 6.x for both 32 bit and 64 bit.

When the installation process is complete, you need the tools to connect with the Centos server via FTP and protocols, you must to install FileZilla at the URL address :

Next, we need to install Putty to communicate with Linux via SSH.

Download the installation package Putty for at the following address :

To prepare for the next section, you need to set up a connection using Putty SSH to Server running Centos, enter the address of the computer running Centos (probably on the dedicated server, on the virtual machines, on the your LAN or PC).

Connect Putty

After setting up SSH connection successful, we will move on to step installing the system.


Update the System

For convenience in the next section, we follow the way :

  • Select and copy command (CTRL + C)
  • Right-click into the Putty window to Paste command and press Enter to execute

Copy and execute the following command to update the critical components of the system :

yum update

Yum Update

After the update completed, we need to restart the system using the following command :


Install the dependencies packages

These are the basic software packages for environment settings and utility tools to compile other packages in the next section.

Copy the block command and execute in the Putty Windows :

This is a long command line, copy all and implementation.

yum -y install nano zip unzip libyaml-devel zlib-devel curl-devel openssl-devel -devel apr-devel apr-util-devel -devel gcc ruby-devel gcc-c++ make postgresql-devel ImageMagick-devel sqlite-devel -LDAP mod_ perl-Digest-SHA

Install Packages

Install Apache and MySQL

Apache is a server application for communicating over the HTTP protocol. Apache runs on operating systems such as Unix, Linux, Windows, and other operating systems.

Apache play an important role in the development of the internet and the world wide web.

MySQL is the database management free open source most popular on the world, MySQL has high speed, stability and ease of use, portability, operating on multiple operating systems offer a large system is very powerful utility functions.

With the speed and high , MySQL is well suited for applications that access databases on the internet.

Use the following command to install :

yum -y install httpd mysql mysql-server

Install Apache Mysql

Allow start services when OS boot :

chkconfig httpd on
chkconfig mysqld on
service httpd start
service mysqld start

Set the password for MySQL


Because we not have a password for the account so you press Enter to skip.

Enter current password for root (enter for none):

Select Yes to set the password for the MySQL root account.

Set root password? [Y/n] y

Enter and confirm your password, remove the anonymous user, select Yes

Remove anonymous users? [Y/n] y

Allow remote login to MySQL as root account, select No.

Disallow root login remotely? [Y/n] n

Delete the test database, select Yes

Remove test database and access to it? [Y/n] y

Reload privilege tables, select Yes

Reload privilege tables now? [Y/n] y

Turn off SELinux

SELinux is a security feature advanced for Linux operating system, when installing the system you need to turn off this feature to get the process done smoothly, after successful you can turn on back if you want.

nano /etc/selinux/config

Change the file content :


Edit SELinux

Press CTRL + O to save the file and press CTRL + X to exit.

Set up the Hostname

By default when installing a new OS Centos not set the hostname, so we need to setting with the command :

nano /etc/hosts

Set Hostname

Add your domain name or host name that you set on both the command line, save the file and exit, the server name will be changed when restarting.

Configuring the Firewall

We do not want to turn off the firewall because it’s quite important, so you need to add rules to allow port 80 for HTTP and port 443 for HTTPS.

In the Centos OS, you can configuration firewall by editing files iptables and ip6tables.

nano /etc/sysconfig/iptables

Config Firewall

Press Enter to create a new line after the line of port 22, copy the following two commands and right click on the window to the Paste command.

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

Press CTRL + O to save the file and press CTRL + X to exit.

The same applies for IP6 firewall :

nano /etc/sysconfig/ip6tables

Add these lines to the file.

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

After you finish editing both files, run the commands to apply the new rules for firewall.

/etc/init.d/iptables restart
/etc/init.d/ip6tables restart

Allow turn on the firewall when reboot the operating system.

chkconfig iptables on
chkconfig ip6tables on

Finally, we need to restart the system to apply the changes to the SELinux and Hostname.


Install PHP and phpMyAdmin

Because we use MySQL database management system, so we need to install phpMyAdmin program management.

phpMyAdmin is a free open source tool written by PHP language to manage MySQL database via a web browser.

It can create, modify or delete databases, tables, fields or records, perform SQL statements, or managing users and permissions.

The command to install PHP and the packages :

yum -y install php php-mysql php-gd php-imap php-ldap php-mbstring php-odbc php-pear php-xml php-xmlrpc php-pecl-apc php-soap

Install PHP

Restarting the Apache service :

service httpd restart

And install phpMyadmin :

rpm --import
yum install
yum -y install phpmyadmin

Install php Myadmin

Editing the virtual host file to allow remote login to the phpMyadmin.

nano /etc/httpd/conf.d/phpmyadmin.conf

Edit VirtualHost PHP Myadmin

Replace text “Allow from” to “Allow from all”, save the file and exit.

Editing the configuration file for the phpMyadmin

nano /usr/share/phpmyadmin/

Edit Config PHP Myadmin

Replace text :

$cfg['Servers'][$i]['auth_type'] = 'cookie';

To :

$cfg['Servers'][$i]['auth_type'] = 'http';

Save the file and exit, restarting the Apache service :

service httpd restart

After successfully installed phpMyadmin, you can check at the address :


Login with account : root / your_password

With Password has been set at step install MySQL database in the above.


Note: If you install the Redmine system on the PC or in a virtual machine which not on the dedicated server, we need to switch the application phpMyadmin to run on port 8080 because port 80 will be used for Redmine in the next steps.

We need add a port 8080 to the firewall and change the VirtualHost for phpMyadmin.

nano /etc/sysconfig/iptables


Add the command line :

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

The same applies for IP6 firewall :

nano /etc/sysconfig/ip6tables

Add the command line :

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

Restarting firewall service to allow the new port.

/etc/init.d/iptables restart
/etc/init.d/ip6tables restart

Editing the VirtualHost file to run phpMyadmin on the port 8080

nano /etc/httpd/conf/httpd.conf


Change the file content :

<VirtualHost *:8080>
    DocumentRoot /usr/share/phpmyadmin/

Next, add the command to allows listening on the port 8080 in the file “httpd.conf”

nano /etc/httpd/conf/httpd.conf


Add the command line :

Listen 8080

Save the file and exit, restarting the Apache service :

service httpd restart


Now, phpMyadmin will run on the port 8080 at the address :


Install Ruby

Ruby is a object-oriented programming language, capable of reflection. Syntax inherited from Ada and Perl with object-oriented features of Smalltalk, and also share some features with Python, Lisp, Dylan and CLU, Ruby is a single phase interpreter.

Ruby provides programming patterns, including functional programming, object-oriented, imperative, reflective, it uses dynamic variable and automatic memory management.

Install Ruby interpreter with version management program RVM.

\curl -L | bash

After successful, we will launch RVM

source /etc/profile.d/

The following command will list the versions of Ruby to install :

rvm list known


We choose the stable version [ruby-] 1.9.3 [-p545], and execute the following command :

rvm install 1.9.3


The installation process is pretty long time, but you do not need any intervention, after successful, you check with the following command :

ruby -v

Install Rubygems

Rubygems is a Ruby’s packages management program, very popular in applications written by Ruby language and the Ruby On Rails framework.

yum -y install rubygems


Install Passenger

The full name of the Passenger is Phusion Passenger, known as mod_rails or mod_rack, it is a web application intergrate with Apache and it can operate as a standalone web server support for the Ruby On Rails applications.

Execute the following commands :

gem install passenger


After completed, we copy a notification block in the window to create the configuration file in the next steps (select block notification and press C to copy).

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p545/gems/passenger-4.0.37/buildout/apache2/
<IfModule mod_passenger.c>
   PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p545/gems/passenger-4.0.37
   PassengerDefaultRuby /usr/local/rvm/gems/ruby-1.9.3-p545/wrappers/ruby

Create a new virtual host file for Passenger :

nano /etc/httpd/conf.d/passenger.conf

Paste the command blocks into the empty file and save it, then restart the Apache service.

service httpd restart

Create Database for Redmine

Use MySQLAdmin to create an empty database for Redmine, saved password to fill in the configuration file in the next steps.

mysql --user=root --password=root_password_mysql
create database redmine_db character set utf8;
create user 'redmine_admin'@'localhost' identified by 'your_new_password';
grant all privileges on redmine_db.* to 'redmine_admin'@'localhost';


Install Redmine

Redmine is a main program of the project management system, we will download and install the program from the website of Redmine.

Download Redmine version 2.5.x to directory “/var/www” on the Centos OS.

cd /var/www

Extract the folder and rename directory

tar xvfz redmine-2.5.0.tar.gz
mv redmine-2.5.0 redmine
rm -rf redmine-2.5.0.tar.gz

Configuring the Database

The next, we need to configure the database was created from the above steps.

cd /var/www/redmine/config
cp database.yml.example database.yml
nano database.yml


Enter name for database, enter username and password of the database. Press CTRL + O to save the file and CTRL + X to exit.

Setting up Rails

Install the package library support for Rails using the Bundle.

cd /var/www/redmine
gem install bundler
bundle install
rake generate_secret_token


The next, we create the database table for the Redmine application.

RAILS_ENV=production rake db:migrate
RAILS_ENV=production rake redmine:load_default_data

Activate FCGI

cd /var/www/redmine/public
mkdir plugin_assets
cp dispatch.fcgi.example dispatch.fcgi
cp htaccess.fcgi.example .htaccess

Setting up Apache and FastCGI

cd /var/www/
rpm --import
rpm -ivh epel-release-6-8.noarch.rpm
yum -y install mod_fcgid
rm -rf epel-release-6-8.noarch.rpm

Creating Files Directory

This directory contains data files generated during the operation of Redmine as document or image file, we create a new directory in the “/opt”.

mkdir -p /opt/redmine/files
chown -R apache:apache /opt/redmine
cd /var/www/redmine/config
cp configuration.yml.example configuration.yml
nano configuration.yml


Enter the directory path containing the data files you just created in the previous step into the line “attachments_storage_path”.

Note: You must add a space at the begin of the path “/opt/redmine/files” after character “:”


Another very important function of Redmine is using email to notify members when the contents of each project changes, Redmine can use many different methods to send email that is Sendmail, SMTP, GMail …

To configure the email we will edit the configuration file.

nano /var/www/redmine/config/configuration.yml

The simplest is you use features of the default SendMail in the Centos OS by settings :

   delivery_method: :sendmail

Note : Do not use the Tab key to indent when editing the configuration file, you need to use the space bar on the keyboard.

If you use GMail’s SMTP, you need to register an email account with the login methods used password normal and disable two-step authentication by smart phone.

Enter your Gmail account as below :

   delivery_method: :smtp
        enable_starttls_auto: true
        address: "" 
        port: 587
        domain: "" 
        authentication: :plain
        user_name: "" 
        password: "your_password" 

Save the file configuration and exit.

Create Virtual Host for Redmine

Create an Apache configuration file for the Redmine application at the port 80.

nano /etc/httpd/conf.d/redmine.conf

Copy the text below and paste into the editor window, note the information to change your domain name.

<VirtualHost *:80>
        ServerName your_domain
        DocumentRoot /var/www/redmine/public/
        ErrorLog logs/redmine_error_log
        <Directory "/var/www/redmine/public/">
                Options Indexes ExecCGI FollowSymLinks
                Order allow,deny
                Allow from all
                AllowOverride all

Save the file configuration and exit.

Running Redmine

Before execute Redmine in the first time, we must permission for the directory installed Redmine and restart Apache service.

cd /var/www
chown -R apache:apache redmine
chmod -R 755 redmine
service httpd restart


Redmine will run at the following address URL :


Login to system with an administrator account : admin / admin

You can change your password after successful login.

We can see Redmine has running but very primitive, in the next steps we will install the support plugins and customized Redmine to use professional.

Install Subversion

Subversion, also known as SVN, it is a version management system is very popular and easy to use, most programmers can use it competently.

We need to create a folder to store data for Redmine, the following command creates a directory and permissions for the Apache service.

mkdir -p /opt/repositories/svn
chown -R apache:apache /opt/repositories/
chmod 0755 /opt/repositories

The following command install Subversion and the packages :

yum install mod_dav_svn subversion subversion-ruby


The next, we will create a directory and copy the file called “”, it responsible for interface data repository with Redmine and it is written by Perl language programming.

mkdir /usr/lib64/perl5/vendor_perl/Apache
ln -s /var/www/redmine/extra/svn/ /usr/lib64/perl5/vendor_perl/Apache/

Note : If you are using 32 bit Centos, change the path “/usr/lib64” to “/usr/lib”

After installation is complete, from the Redmine application, go to the page Administration> Settings> Repositories to check the results.

To support the authentication and access to data repository for each member, we need to create a virtual host for the Apache service can access Redmine database.

nano /etc/httpd/conf.d/subversion.conf

Add the following lines to the end and still retain the old contents of the file :

PerlLoadModule Apache::Redmine
<Location /svn>
        DAV svn
        SVNParentPath "/opt/repositories/svn" 
        SVNListParentPath on
        Order deny,allow
        Deny from all
        Satisfy any
        LimitXMLRequestBody 0
        SVNPathAuthz off
        PerlAccessHandler Apache::Authn::Redmine::access_handler
        PerlAuthenHandler Apache::Authn::Redmine::authen_handler
        AuthType Basic
        AuthName "Subversion Repository" 
        Require valid-user
        RedmineDSN "DBI:mysql:database=redmine_db;host=localhost:3306" 
        RedmineDbUser "redmine_admin" 
        RedmineDbPass "your_password_database_redmine" 

Note : You need to change the password in the “RedmineDbPass” to correct the database password of Redmine.

At this point, we have finished the basic settings for Redmine.

Thank you!
