Intro

Basics

  • List the available modules of the Apache HTTP server
apache2 -l
  • Main configuration file for the Apache Http server
/etc/apache2/apache2.conf
  • The error log of Apache is located in the
/var/log/apache2/error.log
grep MaxClients /var/log/apache2/error.log

Multi-Processing-Module

Apache HTTP can run in different modes. MPM modes determine how the web requests of users are answered.

  • The selected mode is compiled into the server and can be checked with:
sudo apachectl -V | grep -i mpm


  • Configuration for the event mpm is stored in below file:

  • The following .htacess file reroutes http://aman.info.tm to http://www.aman.info.tm.
  • It also redirect access to a certain webpage (/articles/SpringFramework/article.html) to another webpage via a 301 redirect.
  • The 301 redirect will tell search engines that this side has moved and is the recommended way to move webpages.
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.vogella\.de$
RewriteRule ^(.*)$ http://www.aman.info.tm/$1 [L,R=301]
redirect 301 /articles/SpringFramework/article.html http://www.vogella.com/tutorials/SpringDependencyInjection/article.html
