Apache VirtualHost , Mongrel Cluster for rimu's hosting services Here is the file that worked for me (for Apache 2.0) NameVirtualHost *:80 ServerName myapp.com ServerAlias www.myapp.com DocumentRoot /var/www/yycctw/public Options FollowSymLinks AllowOverride None Order allow,deny Allow from all ProxyPass / http://127.0.0.1:8000/ ProxyPassReverse / http://127.0.0.1:8000 ProxyPreserveHost on ProxyPass /images ! ProxyPass /stylesheets ! ProxyPass /excerpt ! ProxyPass /javascripts !

Installing Gems on Shared Hosting service (like Dreamhost) First, you need to setup your .bash_profile. If you haven't already done it and make a directory for your gems. mkdir .gems echo 'export GEM_HOME="$HOME/.gems"' >> .bash_profile echo 'export GEM_PATH="$GEM_HOME:/usr/lib/ruby/gems/1.8"' >> .bash_profile echo 'export PATH="$HOME/.gems/bin:$PATH"' >> .bash_profile Of course, you could edit your .bash_profile using pico, nano or vi if you prefer. Then be sure to load all that: source .bash_profile If all goes well, you should be able to then install your own gems, update ones that are already there, and generally be a happier person. For example, you could update your rails gem with gem update rails --include-dependencies All of your personally-installed gems will end up in ~/.gems for you to use. (from dreamhost wiki)
