Shell script: create virtual hosts with PHP/fastCGI (mod_fcgi)

UPDATES:

Version 1.1 – June 20 2011

  • Added ¬†“FcgidMaxRequestLen 1000000000” to virtual host settings in order to get the WordPress Flash based image uploader to work. The default value in fcgid caused it to throw a “HTTP Error” when crunching the images.
  • Commented out the Apache directive “ServerAlias” which in previous version defaulted to *.example.com. That of course might cause problems when setting up both root domain and sub domains on the same server. Feel free to uncomment or add custom aliases.
  • Moved the ports.conf tip from script echo to comments at the end.

# Make sure you edit /etc/apache2/ports.conf and add another NameVirtualHost
# if you want your server to listen to additional ports, ie 8080 for proxying.
