# Gunicorn
|
||||
|
||||
Like most Django applications, NetBox runs as a [WSGI application](https://en.wikipedia.org/wiki/Web_Server_Gateway_Interface) behind an HTTP server. This documentation shows how to install and configure [gunicorn](http://gunicorn.org/) (which is automatically installed with NetBox) for this role, however other WSGI servers are available and should work similarly well. [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/) is a popular alternative.
|
||||
!!! tip
|
||||
This page provides instructions for setting up the [gunicorn](http://gunicorn.org/) WSGI server. If you plan to use [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/) instead, go [here](./4b-uwsgi.md).

## Configuration
|
||||
|
||||
NetBox ships with a default configuration file for gunicorn. To use it, copy `/opt/netbox/contrib/gunicorn.py` to `/opt/netbox/gunicorn.py`. (We make a copy of this file rather than pointing to it directly to ensure that any local changes to it do not get overwritten by a future upgrade.)

# uWSGI
|
||||
|
||||
!!! tip
|
||||
This page provides instructions for setting up the [uWSGI](https://uwsgi-docs.readthedocs.io/) WSGI server. If you plan to use [gunicorn](http://gunicorn.org/) instead, go [here](./4a-gunicorn.md).
|
||||
|
||||
NetBox runs as a [WSGI application](https://en.wikipedia.org/wiki/Web_Server_Gateway_Interface) behind an HTTP server. This documentation shows how to install and configure [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/) for this role, however other WSGI servers are available and should work similarly well.
|
||||
|
||||
## Installation
|
||||
|
||||
Activate the Python virtual environment and install the `pyuwsgi` package using pip:
|
||||
|
||||
```no-highlight
|
||||
source /opt/netbox/venv/bin/activate
|
||||
pip3 install pyuwsgi
|
||||
```
|
||||
|
||||
Once installed, add the package to `local_requirements.txt` to ensure it is re-installed during future rebuilds of the virtual environment:
|
||||
|
||||
```no-highlight
|
||||
sudo sh -c "echo 'pyuwgsi' >> /opt/netbox/local_requirements.txt"
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
NetBox ships with a default configuration file for uWSGI. To use it, copy `/opt/netbox/contrib/uwsgi.ini` to `/opt/netbox/uwsgi.ini`. (We make a copy of this file rather than pointing to it directly to ensure that any local changes to it do not get overwritten during a future NetBox upgrade.)
|
||||
|
||||
```no-highlight
|
||||
sudo cp /opt/netbox/contrib/uwsgi.ini /opt/netbox/uwsgi.ini
|
||||
```
|
||||
|
||||
While the provided configuration should suffice for most initial installations, you may wish to edit this file to change the bound IP address and/or port number, or to make performance-related adjustments. See [the uWSGI documentation](https://uwsgi-docs-additions.readthedocs.io/en/latest/Options.html) for the available configuration parameters and take a minute to review the [Things to know](https://uwsgi-docs.readthedocs.io/en/latest/ThingsToKnow.html) page. Django also provides [additional documentation](https://docs.djangoproject.com/en/5.0/howto/deployment/wsgi/uwsgi/) on configuring uWSGI with a Django app.
|
||||
|
||||
## systemd Setup
|
||||
|
||||
We'll use systemd to control both uWSGI and NetBox's background worker process. First, copy `contrib/netbox.service` and `contrib/netbox-rq.service` to the `/etc/systemd/system/` directory.
|
||||
|
||||
```no-highlight
|
||||
sudo cp -v /opt/netbox/contrib/*.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
```
|
||||
|
||||
The reference configuration assumes that gunicorn is in use, so we need to update it. Edit the `netbox.service` file to remove the line beginning with `ExecStart=/opt/netbox/venv/bin/gunicorn` and uncomment the line below it.
|
||||
|
||||
!!! warning "Check user & group assignment"
|
||||
The stock service configuration files packaged with NetBox assume that the service will run with the `netbox` user and group names. If these differ on your installation, be sure to update the service files accordingly.
|
||||
|
||||
Once the configuration file has been saved, reload the service:
|
||||
|
||||
```no-highlight
|
||||
sudo systemctl daemon-reload
|
||||
```
|
||||
|
||||
Then, start the `netbox` and `netbox-rq` services and enable them to initiate at boot time:
|
||||
|
||||
```no-highlight
|
||||
sudo systemctl enable --now netbox netbox-rq
|
||||
```
|
||||
|
||||
You can use the command `systemctl status netbox` to verify that the WSGI service is running:
|
||||
|
||||
```no-highlight
|
||||
systemctl status netbox.service
|
||||
```
|
||||
|
||||
You should see output similar to the following:

||||
|
||||

```
|
||||
|
||||
!!! note
|
||||
If the NetBox service fails to start, issue the command `journalctl -eu netbox` to check for log messages that may indicate the problem.
|
||||
|
||||
Once you've verified that the WSGI workers are up and running, move on to HTTP server setup.
|
||||
|
||||
## HTTP Server Installation
|
||||
|
||||
For server installation, you will want to follow the NetBox [HTTP Server Setup](5-http-server.md) guide, however after copying the configuration file, you will need to edit the file and change the `location` section to uncomment the uWSGI parameters:
|
||||
|
||||
```no-highlight
|
||||
location / {
|
||||
# proxy_pass http://127.0.0.1:8001;
|
||||
# proxy_set_header X-Forwarded-Host $http_host;
|
||||
# proxy_set_header X-Real-IP $remote_addr;
|
||||
# proxy_set_header X-Forwarded-Proto $scheme;
|
||||
# comment the lines above and uncomment the lines below if using uWSGI
|
||||
include uwsgi_params;
|
||||
uwsgi_pass 127.0.0.1:8001;
|
||||
uwsgi_param Host $host;
|
||||
uwsgi_param X-Real-IP $remote_addr;
|
||||
uwsgi_param X-Forwarded-For $proxy_add_x_forwarded_for;
|
||||
uwsgi_param X-Forwarded-Proto $http_x_forwarded_proto;
|
||||
}
|
||||
```

|
||||
sudo cp /opt/netbox/contrib/nginx.conf /etc/nginx/sites-available/netbox

```
|
||||
|
||||
!!! tip "gunicorn vs. uWSGI"
|
||||
The reference nginx configuration file assumes that gunicorn is in use. If using uWSGI instead, you'll need to remove the gunicorn-specific configuration (lines beginning with `proxy_pass` and `proxy_set_header`) and uncomment the uWSGI section below them before proceeding.
|
||||
|
||||
Then, delete `/etc/nginx/sites-enabled/default` and create a symlink in the `sites-enabled` directory to the configuration file you just created.
