I update rails from 2.0.2 to 2.2.3. I enter the command ruby script/server, it always start mongrel by default before, but now the server start webrick. How can I start the server by mongrel now?
Have you updated mongrel gem as well?
try to install mongrel again.. have you updated rails properly?
How do you update your rails? Use the gem or not?
Maybe you should reinstall your mongrel.
The default server was changed to webrick. Assuming you have already installed mongrel (gem install mongrel) then you can just type:
script/server mongrel
