Installing the API with uwsgi

Installing the API with uwsgi

Aodh comes with a few example files for configuring the API service to run behind Apache with mod_wsgi.

app.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.

Example of uwsgi configuration file

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

Configuring with uwsgi-plugin-python on Debian/Ubuntu

Install the Python plugin for uwsgi:

apt-get install uwsgi-plugin-python

Run the server:

uwsgi_python –master –die-on-term –logto /var/log/aodh/aodh-api.log
–http-socket :8042 –wsgi-file /usr/share/aodh-common/app.wsgi
