Using Apache with RewriteMap and a text file

jrobertson (James Robertson) — Thu, 25 Oct 2007 22:51:14 GMT

This code will read a text file using Apache then upon a user request, look for a url containing /l/ eg. http://mysite.com/l/digg and rewrite the URL in full eg. http://mysite.com/gwd/feed/digg.html . The example file is shown here for completeness.

RewriteMap uses a text file as a convenient alternative for the administrator when declaring many rewrite rules. Code based on the article from ONLamp.com - A Day in the Life of #Apache http://urltea.com/1vwb





scotsman /gwd/feed/scotsman.html

digg /gwd/feed/digg.html







RewriteEngine on

RewriteMap links txt:/var/www/localhost/links.txt

RewriteRule ^/l/(.*) ${links:$1|http://mysite.com/} [R]

Note: The [R] at the end of RewriteRule means redirect, to have a clean url simply remove that switch.

*update 15-Feb-08 *
Restart Apache rather reloading the module when switching redirection on or off for a RewriteRule. The Apache version 2.2.6 (Unix) didn't pick up my settings correctly when I tried /etc/init.d/apache2 reload, instead I needed to use /etc/init.d/apache2 restart.

A simple mod_rewrite example

jrobertson (James Robertson) — Wed, 24 Oct 2007 09:11:02 GMT

Rewrite a long url as a short easy to remember url with mod_rewrite. Place this code in httpd.conf or the virtual hosts file. Original code from sitepoint - mod_rewrite: A Beginner's Guide to URL Rewriting http://urltea.com/1v6d .

Mongrel and Apache fun with Capistrano 2.0

hmans (Hendrik Mans) — Fri, 07 Sep 2007 16:31:34 GMT

I got the Mongrel recipes from somewhere else -- I sadly don't remember where -- and modified them a bit.



namespace :deploy do

  namespace :mongrel do

    [ :stop, :start, :restart ].each do |t|

      desc "#{t.to_s.capitalize} the mongrel appserver"

      task t, :roles => :app do

        run "mongrel_rails cluster::#{t.to_s} --clean -C #{mongrel_conf}"

      end

    end

  end

  

  namespace :apache do

    desc "Start Apache"

    task :start, :roles => :web do

      sudo "/etc/init.d/httpd start > /dev/null"

    end



    desc "Stop Apache"

    task :stop, :roles => :web do

      sudo "/etc/init.d/httpd stop > /dev/null"

    end



    desc "Restart Apache"

    task :restart, :roles => :web do

      sudo "/etc/init.d/httpd restart > /dev/null"

    end

  end



  desc "Custom restart task for mongrel cluster"

  task :restart do

    deploy.mongrel.restart

    deploy.apache.restart

  end



  desc "Custom start task for mongrel cluster"

  task :start, :roles => :app do

    deploy.mongrel.start

    deploy.apache.start

  end



  desc "Custom stop task for mongrel cluster"

  task :stop, :roles => :app do

    deploy.apache.stop

    deploy.mongrel.stop

  end



end

Make sure your site (or directory) is SSL encrypted

Need a simple way to make sure all http requests get redirected to https?
This apache config snippet will redirect all requests at or below the specified location to its https equivilant.

Glossword WAMP source code (NSIS)

// NSIS (http://nsis.sourceforge.net/)
// Glossword WAMP (http://sourceforge.net/projects/glossword/)
// Apache, MySQL and PHP are stored in archive usr.exe, directory /usr/local
// phpMyAdmin is in archive htdocs.exe, directory /htdocs/phpmyadmin
// Additionaly you need files with phrases: English.nsh and Russian.nsh
// ------------------------------------------
// English.nsh:
// LangString SECT_01 ${LANG_ENGLISH} "Glossword ${PRODUCT_VERSION}"
// LangString TXT_02 ${LANG_ENGLISH} "Thank you for installing Glossword.\r\nFor news and updates go to http://sourceforge.net/projects/glossword/"
// LangString DESC_SecGw ${LANG_ENGLISH} "Glossword program core files."
// ------------------------------------------
// install.bat
// @echo on
// cls
// SET ipath=%1
// cd "%ipath%/usr/local/apache2/bin"
// httpd.exe -k install -n Apache2_GW
// httpd.exe -k start -n Apache2_GW
