I have a server where user can connect to and create their own
websites automatically. For this I use mod_wsgi in daemon mode with
predefined users for processes. Each site runs on it's own process.
The configuration file looks like this:
WSGIDaemonProcess site-1 user=site-1 group=nobody maximum-requests=300
inactivity-timeout=300
WSGIDaemonProcess site-2 user=site-2 group=nobody maximum-requests=300
inactivity-timeout=300
WSGIDaemonProcess site-3 user=site-3 group=nobody maximum-requests=300
inactivity-timeout=300
... (with a lot of lines like these ones)
WSGIProcessGroup %{ENV:PROCESS_GROUP}
WSGIApplicationGroup %{GLOBAL}
I also use nginx as a front-end server for serving static files and I
proxy other requests to apache.
My problem is that whenever a process has been closed due to
inactivity and it needs to start again it would take around 5s if it
is the only one starting then, and can get to a lot more if I have 10
or 20 processes starting at the same time. Also this time can go over
my limits set in nginx configuration for timeout and I could get a 504
response from nginx. I need to use inactivity-timeout because I have
around 600 processes at the moment and the number is increasing and
each process uses around 20 to 25 MB of memory, so I would run out of
memory and get to use the swap if I did not use use it. I also use
maximum-requests in order to keep the process memory lower.
I am looking for any idea that would help me start a process faster,
or improve memory consumption. From what I understand this is because
each process has to load python and django thus the memory and time. I
there any way to improve this? How does WSGIProcessGroup and
ApplicationGroup help, are there better settings?
Also I would like to know if there are any apache options that I need
to play with?
RLimitMEM 205024597
RLimitCPU 240
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
Do I need to change add anything else, like # MaxSpareServers,
MinSpareServers, StartServersThank you, Virgil Balibanu -- You received this message because you are subscribed to the Google Groups "modwsgi" group.
