Task management

Now that things are growing, it’s probably time to reorganise a little.

Since we’re going to be running two services, we might as well keep them (and their logging) in separate directories. Let’s move the http config into /srv/www/http/, and, for consistency, call it uwsgi.ini:

/srv/www/
+- http/
|  +- logs/
|  +- uwsgi.ini
+- project/
   +- code/
   +- static/
   +- logs/
   +- venv/
   +- uwsgi.ini

Now we can configure --emperor to look for ini files as /srv/www/*/uwsgi.ini.

If we now look at our process list, you may notice quicky that we can’t tell which one is our HTTP worker, and which is our App! One again, uWSGI provides, with a series of options to control the process name (or procname):

--procname-prefix                      add a prefix to the process names
--procname-prefix-spaced               add a spaced prefix to the process names
--procname-append                      append a string to process names
--procname                             set process names
--procname-master                      set master process name
--emperor-procname                     set the Emperor process name

To make our lives easier, we can use another Magic Variable to set the name for us: %c - the name of the directory containing the config file.

http.ini

[uwsgi]
strict = true
master = true
chdir = %d

procname-prefix = %c
http = :8000
http-keepalive = 1
http-auto-gzip = true
http-to = 127.0.0.1:8001

processes = 0

req-logger = file:logs/request.log
logger = file:logs/uwsgi.log
