Redmine

h1. HowTo Install Redmine on Ubuntu step by step

p. This tutorial walks you step-by-step through installing Redmine on a clean/fresh Ubuntu 12.04 installation.  This is intended to be a complete cookbook method for getting Redmine installed and running.  It makes no assumptions about other things being installed or configured.  Since I have had some issues when using the graphical package managers, we will be doing this from the command line prompt to keep things as clear and clean as possible.

p. I recommend that you install any Ubuntu updates prior to beginning this process.  There are almost always some waiting to be applied after Ubuntu is first set up.

h2. Prerequisites:  Apache, mod-passenger, and MySQL

p. There are several support packages that we will install first.  The apache installation is pretty simple if you just follow the prompts and accept the defaults.

<pre>$ sudo apt-get install apache2 libapache2-mod-passenger</pre>

Installing mysql takes just a little more, so the details are spelled out.

<pre>$ sudo apt-get install mysql-server mysql-client </pre>

p. The installation process for mysql is going to prompt you for a password for the "root" access for the database server, then ask you to confirm the password in a follow-up screen.  This sets the database adminstration password.

<pre>Package configuration

h2. Installing and configuring the Ubuntu Redmine package

   └────────────────────────────────┘   

</pre>

h2. Configuring Apache

p. You need to modify two files for apache.  The first is /etc/apache2/mods-available/passenger.conf which needs the text *PassengerDefaultUser www-data* added as seen here:

<pre>

<IfModule mod_passenger.c>

  PassengerDefaultUser www-data

  PassengerRoot /usr

  PassengerRuby /usr/bin/ruby

</IfModule>

</pre>

Now create a symlink to connect Redmine into the web document space:

<pre>

$ sudo ln -s /usr/share/redmine/public /var/www/redmine

</pre>

p. And modify /etc/apache2/sites-available/default to insert the following with the other <Directory> sections so that apache knows to follow the symlink into Rails:

<pre>

<Directory /var/www/redmine>

	RailsBaseURI /redmine

	PassengerResolveSymlinksInDocumentRoot on

</Directory>

</pre>

Now restart apache:

<pre>

$ sudo service apache2 restart

</pre>

p. You should now be able to access redmine from the local host

<pre>$ firefox http://127.0.0.1/redmine

</pre>

p. In the upper right corner of the browser window you should see the "Sign in" link.  Click that and enter "admin" at both the *Login:* and *Password:* prompts.  Note: _this is not the password you set during the installation process_.  Click the *Login* button.

p. I recommend that the next thing you do is to click on *My account* in the upper right corner and change that password.  In the page that is displayed there should be a *Change password* link in the upper right of the white area of the page.  Click to change the password.

h2. Backing up Redmine

p. You should arrange a regular backup of the Redmine database and the files that users upload/attach.  The database can be dumped to a text file with:

<pre>/usr/bin/mysqldump -u root -p<password> redmine_default | gzip > /path/to/backups/redmine_db_`date +%y_%m_%d`.gz</pre>where <password> is the one you set when installing mysql.

p. The attachments are stashed in /var/lib/redmine/default/files and can be backed up with something like:

<pre>rsync -a /var/lib/redmine/default/files /path/to/backups/files</pre>

p. You can have these commands run automatically by creating a script called /etc/cron.daily/redmine that contains:

<pre>#!/bin/sh

/usr/bin/mysqldump -u root -p<password> redmine_default | gzip > /path/to/backups/redmine_db_`date +%y_%m_%d`.gz

rsync -a /var/lib/redmine/default/files /path/to/backups/files</pre>

p. Again, be sure to substitute the mysql root password for <password> in the mysqldump command line.  The file should be protected so that only root has read permission because you are storing the root password for your mysql installation in this file.  That the first line creates a new file every time the script is run.  This can eventually create a large number of backups of your database files.  You should have a script that purges old ones periodically.

h1. Additional semi-optional packages

There are some services that Redmine can use that are not absolutely necessary, but are useful.  These are email and software repository/revision control systems.

h2. Email setup

p. At some point you will probably want Redmine to be able to send email.  For this you will need to install and configure email.  This can be achieved by installing the *exim4* package.  There is a good description of this "here":https://help.ubuntu.com/12.04/installation-guide/i386/mail-setup.html.  Unless everyone has an email account on the redmine server you will want to set up external email either as a full internet host, or with a "smarthost" that relays mail for the Redmine server.  Once email service is installed, you will have to restart apache for Redmine to know that it has access to email services.

<pre>$ sudo apt-get install exim4

$ dpkg-reconfigure exim4-config

</pre>

p. Now that you can send email, you have to tell Redmine about it.  You need to create/edit the file */etc/redmine/default/configuration.yml* and add the following lines:

<pre>

production:

  email_delivery:

    delivery_method: :sendmail

</pre>

Then restart apache so that Redmine reloads the configuration file:

<pre>$ sudo service apache2 restart</pre>

h2. Revision control repository setup

p. In order to have your software repository on the system Redmine will need the corresponding software installed.  

<pre>$ sudo apt-get install git subversion cvs mercurial

$ sudo service apache2 restart

</pre>

That covers it as far as I have gotten in my use of Redmine to date.
