Aodh comes with a few example files for configuring the API service to run behind Apache with mod_wsgi.
The file aodh/api/app.wsgi sets up the V2 API WSGI application. The file is installed with the rest of the Aodh application code, and should not need to be modified.
Create aodh-uwsgi.ini file:
[uwsgi]
http = 0.0.0.0:8041
wsgi-file = <path_to_aodh>/aodh/api/app.wsgi
plugins = python
# This is running standalone
master = true
# Set die-on-term & exit-on-reload so that uwsgi shuts down
exit-on-reload = true
die-on-term = true
# uwsgi recommends this to prevent thundering herd on accept.
thunder-lock = true
# Override the default size for headers from the 4k default. (mainly for keystone token)
buffer-size = 65535
enable-threads = true
# Set the number of threads usually with the returns of command nproc
threads = 8
# Make sure the client doesn't try to re-use the connection.
add-header = Connection: close
# Set uid and gip to an appropriate user on your server. In many
# installations ``aodh`` will be correct.
uid = aodh
gid = aodh
Then start the uwsgi server:
uwsgi ./aodh-uwsgi.ini
Or start in background with:
uwsgi -d ./aodh-uwsgi.ini
As Aodh is using Pecan and Pecan’s DebugMiddleware doesn’t support multiple processes, there is no way to set debug mode in the multiprocessing case. To allow multiple processes the DebugMiddleware may be turned off by setting pecan_debug to False in the api section of aodh.conf.
For other WSGI setup you can refer to the pecan deployment documentation. .. pecan deployment: http://pecan.readthedocs.org/en/latest/deployment.html#deployment
