uWSGI

As an alternative to gunicorn, you can also use uWSGI as application server which is considered to be better than gunicorn by some community members.

Installation

CentOS 7&8

# yum install mod_proxy_uwsgi

Debian 10 / 11

# a2enmod proxy_uwsgi

In your Peering Manager folder (usually /opt/peering-manager), run the following command:

# sudo -u peering-manager echo 'uwsgi' >> local_requirements.txt
# sudo -u peering-manager venv/bin/pip install -r local_requirements.txt

To validate functionality, you can execute sudo -u peering-manager venv/bin/uwsgi --http :8001 --module peering_manager.wsgi and navigate to hostname:8001.

Replace or create /etc/systemd/system/peering-manager.service with the following content:

[Unit]
Description=Peering Manager WSGI Service
Documentation=https://peering-manager.readthedocs.io/
After=network-online.target
Wants=network-online.target

KillSignal=SIGQUIT

Configuration

For uWSGI to work, you also have to adjust your webserver configuration with the following snippets.

nginx

upstream django {
    server unix:///run/peering-manager/peering-manager.sock;
}
server {
    location /pm {
        include /etc/nginx/uwsgi_params;
        uwsgi_pass django;
    }
}

Apache

Simply replace the proxy URL with unix:/run/peering-manager/peering-manager.sock|uwsgi://peering-manager/ and load the required module with LoadModule proxy_uwsgi_module modules/mod_proxy_uwsgi.so when on CentOS.

Further tweaking

If you have to handle more requests, you can increase the process or thread count. There are a lot more options, please see the uWSGI documentation for more.
