see: LAMP for details on installing Apache.

Error log report

  • Below is a very simple, quick way to check for (the last 100) errors in your httpd setup:
tail -100 /var/log/httpd/error_log |cut -d']' -f 4-99 |sed -e "s/, referer.*//g"|sort|uniq
  • Search for all errors:
cat /var/log/httpd/error_log |cut -d']' -f 4-99 |sed -e "s/, referer.*//g"|sort|uniq

Note: To monitor the significance, add '-c' to the uniq command, which will find you a count of the number of each error.

Configuration management

apachectl configtest

Updating modules

  • Force CPAN to produce a list of all the modules that have updates and update them:
/usr/bin/perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'

Example VirtualHost domain redirect

see: Rewrite engine for details.
<Directory />
  Options FollowSymLinks
  AllowOverride All
</Directory>

<VirtualHost *:80>

  ServerAdmin admin@example.com
  ServerName  example.com
  ServerAlias www.example.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.html index.php
  DocumentRoot /var/www/html/example.com

  # Rewrite rules
  # Example: http://xtof.ch/skills redirects to http://wiki.christophchamp.com/index.php/Technical_and_Specialized_Skills
  RewriteEngine On
  RewriteRule ^/skills$ http://wiki.christophchamp.com/index.php/Technical_and_Specialized_Skills [R=301,L]

  # Custom log file locations
  LogLevel warn
  ErrorLog  /var/log/httpd/example.com-error.log
