Problem
You are using the script/dbconsole utility in Rails (with sqlite), and you want to exit the application but the usual keystrokes/commands like quit, exit, Ctrl + C don’t work.

Solution
You have to use the following keyword, paying particular notice in the leading dot (.exit):

.exit

Problem
You want to work with sqlite3 in Mandriva (2009), but the standard installation doesn’t work, and you cannot use urpmi sqlite3.

Solution
You need to install the sqlite3 command line tools, like:

urpmi sqlite3-tools

Problem
You have recently installed Mandriva 2009 and you want to install phusion passenger.

Solution

1. First make sure that apache is installed. If it is not installed (default), do:

   urpmi apache

   On the selection question about the dependencies select option 1 (apache-prefork)

2. Use the details from the phusion passenger website. ie:
   Install passenger:

   gem install passenger

3. Run the passenger installation:

   passenger-install-apache2-module

4. If at the second stage of the installation the installer complains that GNU C++ compiler … not found, install the gnu c++ compiler, with:

   urpmi gcc_c++

5. Run the passenger installation (step 3) again. If at this stage the installer complains that Apache 2 development headers … not found, use:

   urpmi apache-devel

6. Run passenger installer (step 3), once more. Now everything should be ok and the apache 2 module will be installed when the installer finishes.
7. Restart the Apache webserver, and you should be able to add your Rails application. Use the following to deploy your application in /somewhere/public:

   <VirtualHost *:80>
     ServerName www.yourhost.com
     DocumentRoot /somewhere/public
   </VirtualHost>
