Apache Worker MPM

[Nathan]

I am pretty sure the early releases of Passenger only allowed for
Prefork MPM yet clearly the preferred method is now Worker MPM. Do I
have to do anything to switch my application from Prefork to Worker
MPM? How exactly do I configure that within Apache?

[Nathan]

Vaguely answering my own question...not sure if this is documented
somewhere and I just missed it:

$ sudo apt-get install apache2-mpm-worker

This will remove prefork and move to "worker". Then edit the apache
configuration file:

$ sudo vim /path/to/apache2/apache2.conf

and edit the worker configuration to contain the following
(recommended by Hong Lai)

<IfModule mpm_worker_module>
StartServers 1
MaxClients 10
MinSpareThreads 1
MaxSpareThreads 1
ThreadsPerChild 10
MaxRequestsPerChild 50000
ThreadStackSize 500000
</IfModule>

Let me know if there is something I am missing or if those values are
not correct / more configuration is missing.

sudo apt-get install apache2-mpm-worker

What about on a mac?

I'm no guru, but my error message, "sudo: apt-get: command not found"
would lead me to believe apt-get doesn't come with Darwin, maybe only
Ubuntu?

Yeah, that was for using worker with Ubuntu. apt-get only exists as a
packaging system in Ubuntu. I only needed worker for production so
that is why I am not sure how to install it for Mac.

Also, can someone verify the settings for worker MPM I pasted as being
reasonable defaults?

Yes, we use the same values on our servers.
