In some very rare situations you may find yourself in the need to recompile a Debian (or Ubuntu) package. Luckily for all of use, the great Debian packaging system makes this a piece of cake.
Let’s say we want to recompile mod_python for apache 2 to hook in to python 2.5, instead of the default 2.4.
Please digg this story to spread the word! Thanks!
Okay, this is a big one! This article will show you (and explain to you) how to setup a Ruby on Rails production server with Ubuntu 7.04 or Debian 4.0 and how to deploy your Rails application there.
First, what’s getting installed:
I assume that you have just installed a fresh system with Ubuntu Linux 7.04 or Debian 4.0. If you haven’t, do so now! You don’t need to install the “DNS” or “LAMP” server in Ubuntu. Just a minimal system is enough for this tutorial.
I’ll be deploy an imaginary Rails application named “myapp” which uses MySQL and is stored in Subversion. More on that later on.
Well, let’s get going and get that Ruby on Rails server ready.
My articles about setting up a Ubuntu Development Server (part 1 and part 2) have been very successful.
I’m considering writing a new guide with more up-to-date information on how to setup a development server that allows you (and your team) to develop software, manage source code, track tickets and all that stuff.
As you may know I manage quite a few trac installations. A few days ago I upgrade my server from Ubuntu “Dapper Drake” 6.06 to Ubuntu “Feisty Fawn” 7.04. This also upgrade trac 0.9.x to 0.10.3.
I was happy, since trac 0.10.3 has many improvements over 0.9.x, but there was one thing I was not so happy about. After the upgrade, I upgraded all my trac installations and everything seemed to be okay, except for the WebAdmin plugin. Apparently it was not installed anymore.
What happened? After upgrading the trac package, the plugins directory was emptied. Well, just re-install the WebAdmin plugin for 0.10.x.
My shiny new VPS, which is running Ubuntu Linux, uses ProFTPD for FTP access. Today I noticed that setting up the connection takes about 5 to 10 seconds. This is really annoying when editing files through FTP.
Also read Part 1 – Subversion.
In this part I will tell you how to install Trac on top of your Subversion repositories on your Ubuntu development server. Trac offers you a wiki, roadmap, tickets (tracking system) and access to your SubVersion repository. All of this is bundeled in a very sexy web interface.
Well, let’s get to work now and get Trac installed. When you’re done you will have trac available for all your Subversion repositories.
Since I’m starting some real work on my final school project, I want to install a Ubuntu development server here at home. I have a Pentium 4 box here that will perform that task.
In this first part I will show you how to install Subversion over WebDAV. All of this will be done in such a way that it’s easy to serve multiple projects at once.
In future parts I will tell you more about installing Trac, FastCGI (with Apache) to host Rails applications and how to use Capistrano to deploy your app properly.
For now, let’s get cracking at Subversion.
Since I teach various Linux courses at Fontys Centrum IT, I want to run a live CD or DVD on my MacBook. First off, here are my specs:
As my Live medium I chose the Ubuntu Linux 6.10 Live DVD. This DVD has several nice options (install server, for example) that I like. It also can boot up in a live desktop environment.
As I was installing my printer on my Ubuntu 6.06 Dapper LTS server with CUPS I noticed the following error:
426 Upgrade Required
After some research I came to the conclusion that CUPS, by default, tries to use SSL whenever possible. So, with this 426 error, you are redirected to the SSL domain. Chances are, you haven’t configured SSL properly, if at all.
In my case, I didn’t want to configure SSL. To get rid of this problem, the key lies in editing your configuration files ( /etc/cups/cupsd.conf ) and adding the following line:
89659a630932acaa0d5abb99bbd3d7e2060
There are several options, Never, IfRequired and Required. By setting this to Never, SSL will never be enforced. Just restart your CUPS server with
89659a630932acaa0d5abb99bbd3d7e2061
and you’re good to go.
