No problem.

Actaully, LSAPI can be started exactly the same way by using a FCGI spawner.

However, we are thinking about a better solution by installing LSWS + ruby LSAPI on each node. As LSAPI processes are managed by LSWS directly, there is no need for spawner and spinner anymore, just let them do nothing or run "lswsctrl start" if LSWS can be started by a normal user (Not sure Capistrano can execute command as 'root' on a remote server or not?).

Only Reaper need to be changed to restart all ruby processes, I think a simple shell command "killall ruby" will do the trick (make sure ruby LSAPI 1.6 is installed). Or, just run "lswsctrl restart" if LSWS is started by a normal user.

We will release LSWS 2.2 soon, which features easy Rails configuration, should be easier than Mongrel, at least for a single server setup.

LSWS + Ruby LSAPI should give better performance on Dynamic pages as well as pages cached in file system than using Mongrel on each cluster node. I believe.

Any comments? Concerns?
