What is Apache? ⌘

  • Many, many modules available

Installing ⌘

  • Included in the standard EL5 repos
  • `yum -y install httpd`

Changing the configuration ⌘

  • Main configuration file at `/etc/httpd/conf/httpd.conf`
  • Syntax check with `service httpd configtest`
  • Re-read config with `service httpd reload`

  • Alternate names can be added via the ServerAlias parameter
  • Multiple names can be specified, separated by a space

Default VirtualHost ⌘

  • The default virtualhost is the one that is the first alphabetically
  • This will be used even if the ServerName/ServerAlias doesn't match if you remove welcome.conf

IP based virtual hosts ⌘

  • What we just created was a name based VirtualHost
  • We can also create address based VirtualHosts
  • These are commonly used with SSL
 DocumentRoot /var/www/html
 CustomLog /var/log/httpd/localhost-access.log combined
 ErrorLog /var/log/httpd/localhost-error.log
