Source control Appliances

Pedro Rainho — Tue, 09 Feb 2010 17:46:24 GMT

In my last post I wrote about how to install and configure Subversion and WebSvn on Ubuntu server. During the search on how to do that I tested two very good appliances. This two appliances are virtual machines that contains the installation of several source control and comes configured out of the box :). All I need is download the appliance and start using. There is no excuse to don’t have a private source control :).

The first appliance is Revision Source Control from TurnKey and it’s an appliance that includes:

Revision Control systems supported: Git, Bazaar, Mercurial, Subversion.
SSL support out of the box.
Webmin module for configuring Apache2.
Includes TurnKey web control panel (convenience).

Again everything it’s installed and configured and ready to use. Just download the appliance and run it on Vmware or Virtualbox.

The next appliance, Trac, it’s also from TurnKey and Integrates source control & project management. The appliance includes:

Revision Control systems supported: Git, Bazaar, Mercurial, Subversion.
SSL support out of the box.
Postfix MTA (bound to localhost) to allow sending of email (e.g., password recovery).
Webmin modules for configuring Apache2 and Postfix.
Trac

These are just two appliances from TurnKey to make a developer life much easy :) again no excuse :P

I invite every one to see TurnKey site they have LOTS of appliances…

Install Subversion and WebSvn on Ubuntu Server

Pedro Rainho — Sat, 06 Feb 2010 19:07:53 GMT

On my last post I wrote about Ubuntu server and Webmin and why I changed WHS with Ubuntu server. Today I'm going to write about Subversion and WebSVN on Ubuntu server. One of the things that I had in WHS was a source control where I stored my code and documents. For that I used VisualSVN. VisualSVN combines Subversion with a web interface of all repositories and also includes user management. To me VisualSVN is the all in one...Veryyy goood product and unfortunately for me VisualSVN is just for Windows :(.

So one of the things I did before move to Ubuntu Server was backup my Subversion repositories so I could restore them on Ubuntu Server.

In Ubuntu Server I had to do install a few packages and do a few steps in order to once again have source control and a web interface. So today I'm going to explain how to install Subversion and WebSVN on Ubuntu server.

The first thing to do is install Subversion and apache package for Subversion. All I need to do is:

sudo aptitude install subversion libapache2-svn

In the next step I need to create a directory where my repositories will be stored. In my case /var/sourcecontrol/svn/. The default location is /var/lib/svn/.

This command will create de directory where all my repositories will be:

sudo mkdir /var/sourcecontrol/svn

After create the directory I copied my entire repository backup from windows into this directory.

Note if I need to create new repositories I just had to do:

sudo svnadmin create /var/sourcecontrol/svn/newRepository

newRepository is the name of the new repository.

Next I need to change the owner of the files in order to access using apache. This can be done with this command:

sudo chown www-data:www-data /var/sourcecontrol/svn/repositoryName -R

repositoryName is the name of the repository.

Next I just need to configure all my repositories to be access in apache. This can be done by editing the file /etc/apache2/mods-available/dav_svn.conf

To edit I just run the command:

sudo nano /etc/apache2/mods-available/dav_svn.conf

Scroll all the way down and add the following code for each repository:

<Location /repositoryName>
DAV svn
SVNPath /var/sourcecontrol/svn/repositoryName
AuthType Basic
AuthName "Subversion repository repositoryName"
</Location>

Next restart the apache :

sudo /etc/init.d/apache2 restart

Open a browser and type http://[serverip]/repositoryName and the repository is now availably in browser.

Notice the /repositoryName in the location is the same as /repositoryName in the url.

After this step you can start doing some checkin's :P

The next step is to install WebSVN. WebSVN is a very good web interface to see all repositories.

The first thing to do is install the package. This can be done with the command:

sudo aptitude install websvn

To have syntax highlight in the source code just install enscript . This can be done with this command:

sudo aptitude install enscript

Now a few things you should know:

During the install of WebSVN three screens will appear:
1 - Select the webserver for configuration.
2 - Specify the path of the subversion repositories, in this case (/var/sourcecontrol/svn).
3 - If all repositories are in the same parent folder leave this in blank otherwise you will have to specify all repositories separated by comma.

The package WebSVN is installed into /usr/share/websvn/, it's necessary to copy to /var/www/. This can be done with the command:

sudo cp -r /usr/share/websvn/ /var/www/

After copy to /var/www it's necessary to edit the file /etc/apache2/mods-available/dav_svn.conf, again with the command:

sudo nano /etc/apache2/mods-available/dav_svn.conf

Next, scroll down and add the following

<Location /websvn/>
Options FollowSymLinks
order allow,deny
allow from all
AuthType Basic
AuthName "Subversion Repository"
</Location>

Save the file and restart apache by doing:

sudo /etc/init.d/apache2 restart

Now just type http://[serverip]/websvn and you will see the WebSVN page and your repositories.

If for some reason your repositories have strange names in just edit the file /etc/websvn/svn_deb_conf.inc with the command :

sudo nano /etc/websvn/svn_deb_conf.inc

In this file you will have something like this:

<?php
// please edit /etc/websvn/config.php
// or use dpkg-reconfigure websvn
$config->parentPath("/var/sourcecontrol/svn/");
$config->addRepository("repositoryName\", file:///var/sourcecontrol/svn/repositoryName1);
$config->addRepository("repositoryName", "file:///var/sourcecontrol/svn/repositoryName2");
$config->setEnscriptPath("/usr/bin");
$config->setSedPath("/bin");
$config->useEnscript();
?>

Here it's possible specify the parent path of all repositories and specify each repository name and location. it's here also that it's specified the path on enscript installed before.

Hope you enjoy the source control and as much as I do :)

Special Thanks for Guerrix and his post on how to install subversion and websvn.

From WHS to Ubuntu Server

Pedro Rainho — Wed, 27 Jan 2010 17:09:17 GMT

A few months ago I bought a license of Windows Home Server to the home server pc I built (see this post). My first encounter with WHS was terrible I did a stupid mistake and I almost delete every single file I had.

The second encounter was much better and every thing was running fine until I noticed here at home and confirmed in the web that WHS is not green and everything was always running at full speed, even when I’m not using it.

So I start looking for alternatives and I saw a project called Amahi that basically It’s a Linux home server with steroids (lots of options and software) and runs on top of Fedora.

I decided not to continue with Amahi, for a few reasons, and started looking for a simple OS that allows me to share files and alternatively have a source control, some databases and then I tested two. One was FreeNas and the other was Ubuntu Server. Since I’m a Ubuntu fan I decided to give a try and create a VM with Ubuntu server + SSH + Apache + MySql + Php (LAMP). Note FreeNas is also very good and it has a impressive web UI.

My first impression wasn’t good because the UI of Ubuntu Server It’s just command line. Alternatively I could install gnome by running this command line: sudo apt-get install ubuntu-desktop

But since I want something simple I decided to continue with the command line but needed something visual that could help me configure the home server. I search around and found Webmin.

Webmin has a demo and lots of screenshots here and Webmin it’s spectacular, a very good web user interface that allows me to configures almost the entire home server and that was just what I needed.

Install Webmin is very simple I just need to run this:

On my computer I opened a command line and run the command ssh [serverIP] and login.
- By doing this I’m now able to run commands on the server. Then I just did
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
- To install a few dependecies and the this
wget http://www.webmin.com/download/deb/webmin-current.deb
- To download the Webmin, and then since the latest version is 1.500 I just need to run this command
sudo dpkg -i webmin_1.500_all.deb
- To Install Webmin

Now I that I have Webmin Installed I just need to open a browser to the URL https://[serverIP]:10000 and I have a UI that allows me to configure my server.

After given a test in a VM I decided definitely to switch from WHS to Ubuntu server with SSH and LAMP and I don’t regret my decision.

Next post will be about install and configure Subversion and WebSvn on Ubuntu Server… And yes my home server also have a source control.

Disable beep on ubuntu shutdown

Pedro Rainho — Tue, 14 Jul 2009 16:59:25 GMT

If you use ubuntu you probably had listen the stupid beep upon reboot/shutdown. To disable this stupid beep just do this:

sudo gedit /etc/modprobe.d/blacklist.conf

And add this

blacklist pcspkr

At the end of the file.

Teboot and no more stupid beep.

This was tested with Ubuntu 9.04 Jaunty
