However, we usually want to run at least two processes.
I have 5 uwsgi processes - I was only seeing the init code run once because I was just sending uwsgi a reload signal. If I killed it and restarted it I was seeing the init code run 5 times. > Running initialization code only once per wsgi server (re)start instead of > once > per process start seems a bit strange. Why do you need this? I had not been given all the requirements. Turns out what we need to do should not be part of the server init, so we moved it somewhere else. > On 2017-09-23 21:50, Larry Martell wrote: >> On Sat, Sep 23, 2017 at 2:39 PM, Larry Martell <[email protected]> >> wrote: >>> On Sat, Sep 23, 2017 at 1:34 PM, James Schneider >>> <[email protected]> wrote: >>>> >>>> On Sep 22, 2017 2:58 PM, "Larry Martell" <[email protected]> wrote: >>>> >>>> We have some code we want to run 1 time when our django app is >>>> started.
