mongrel

Anybody know a nice way to restart a mongrel cluster via capistrano in a "rolling" style, eg, one mongrel at a time. Would be great to have a bit of wait time in there as well for each, to let the mongrel load the rails app up as well. I've done some searching, and haven't found too much, so looking for help before I dive into the mongrel_cluster gem myself. Thanks! I agree with the seesaw approach more than the rolling approach you are seeking. The problem is that you end up in situations where load balancing can throw users back and forth between different versions of the application while

GEMFILE that starts mongrel gem 'rails', '3.1.0' gem 'mongrel', '>=1.2.0.pre2' GEMFILE that start WEBrick (not mongrel) gem 'rails', '3.2.0.rc2' gem 'mongrel', '>=1.2.0.pre2' Starting on Rails 3.2 you must specify the server you want to use, otherwise Webrick will be used. So, to use mongrel, you must place the gem at your Gemfile AND start the server like this: $ rails s mongrel 来源： https://stackoverflow.com/questions/8853338/why-doesnt-mongrel-start-in-rails-3-2-rc

I'm just curious if Passenger does or can utilize clusters like Mongrel can. If so, how can I specifically run Passenger with clusters? I'm using nginx. And if not, how does it outperform Mongrel so well? Mongrel Cluster just runs a specified number of Mongrel processes and assigns incoming HTTP requests to them using Apache's mod_proxy_balancer module which acts as a reverse proxy and performs load balancing. Passenger spawns worker (Ruby) processes to handle HTTP requests using one of three different and configurable strategies . When Passenger's smart spawning method is used it is able to

In Mongrel, we are able to see any ruby debug code. After installing thin and doing thin start . I don't see any debug code on the console window. Is this nromal? Are we supposed to use tail -f log/development.log in a new console window to view the debug code? Yes. The solution with tail is normal, and you should use it. You could also try to start your server this way : rails server thin It shows your log, in Rails 3 at least. You can use a Procfile with foreman : Procfile web: thin start -p $PORT logger: tail -f log/development.log Example $ foreman start -p 3000 Benj The solution is to add

always the first request (of a working session) to my Rails app is lagging. Switching to production mode doesn't help. I use mongrel and the other requests are handled with acceptable speed. How do I make it faster? Regards If you post the contents of the log as that first request is processed then perhaps we can figure out what's making it so slow. For example, this is my log as the first user accesses the site Booting Mongrel (use 'script/server webrick' to force WEBrick) Rails 2.1.0 application starting on http://0.0.0.0:3000 Debugger enabled Call with -d to detach Ctrl-C to shutdown server
