### systemd configuration:
Copy or link contrib/netbox.service and contrib/netbox-rq.service to /etc/systemd/system/netbox.service and /etc/systemd/system/netbox-rq.service
We'll use systemd to control the daemonization of NetBox services. First, copy `contrib/netbox.service` and `contrib/netbox-rq.service` to the `/etc/systemd/system/` directory:
```no-highlight
# cp contrib/netbox.service /etc/systemd/system/netbox.service
# cp contrib/netbox-rq.service /etc/systemd/system/netbox-rq.service
# cp contrib/*.service /etc/systemd/system/
```
Edit /etc/systemd/system/netbox.service and /etc/systemd/system/netbox-rq.service. Be sure to verify the location of the gunicorn executable on your server (e.g. `which gunicorn`). If using CentOS/RHEL. Change the username from `www-data` to `nginx` or `apache`:
!!! note
These service files assume that gunicorn is installed at `/usr/local/bin/gunicorn`. If the output of `which gunicorn` indicates a different path, you'll need to correct the `ExecStart` path in both files.
```no-highlight
/usr/local/bin/gunicorn --pid ${PidPath} --pythonpath ${WorkingDirectory}/netbox --config ${ConfigPath} netbox.wsgi
```
!!! note
You may need to modify the user that the systemd service runs as. Please verify the user for httpd on your specific release and edit both files to match your httpd service under user and group. The username could be "nobody", "nginx", "apache", "www-data" or any number of other usernames.
```no-highlight
User=www-data
Group=www-data
```
Copy contrib/netbox.env to /etc/sysconfig/netbox.env
```no-highlight
# cp contrib/netbox.env /etc/sysconfig/netbox.env
```
Edit /etc/sysconfig/netbox.env and change the settings as required. Update the `WorkingDirectory` variable if needed.
```no-highlight
# Name is the Process Name

Name = 'Netbox'
# ConfigPath is the path to the gunicorn config file.

Copy contrib/gunicorn.conf to gunicorn.conf
```no-highlight
# cp contrib/gunicorn.conf to gunicorn.conf
```
Edit gunicorn.conf and change the settings as required.
```
# Bind is the ip and port that the Netbox WSGI should bind to
#
bind='127.0.0.1:8001'
# Workers is the number of workers that GUnicorn should spawn.
# Workers should be: cores * 2 + 1. So if you have 8 cores, it would be 17.

Finally, start the `netbox` and `netbox-rq` services and enable them to initiate at boot time:

You can use the command `systemctl status netbox` to verify that the WSGI service is running:

```
At this point, you should be able to connect to the HTTP service at the server name or IP address you provided. If you are unable to connect, check that the nginx service is running and properly configured. If you receive a 502 (bad gateway) error, this indicates that gunicorn is misconfigured or not running.

Please keep in mind that the configurations provided here are bare minimums required to get NetBox up and running. You may want to make adjustments to better suit your production environment.
