Conflicting nginx

You should ensure your host is NOT already running nginx which will conflict with xplex .

These following checks are especially necessary if you’re reusing a host system, which may already have nginx installed & running for other services:

Is nginx running as a service/daemon?
Check nginx service status
```
systemctl status nginx
# should be inactive or not found
```
If it shows active or enabled, it’s up to you to decide whether to stop/disable it. It may be running important services on the host, so be careful of stopping or disabling it.
Run the following commands only if you are absolutely sure that removing existing nginx won’t break any critical services on the host, or you don’t care if it does.
Remove previous nginx service from host
```
systemctl stop nginx
systemctl mask nginx
systemctl disable nginx
```
Is nginx running as a process?
Check nginx process status
```
ps aux | grep nginx
```
Even in this case, if it’s running, then it’s up to you to decide whether to stop it. It may break important services on the host, so be careful of stopping it.
Run the following commands only if you are absolutely sure that removing existing nginx won’t break any critical services on the host, or you don’t care if it does.
Stop existing nginx process
```
nginx -s stop
```
Is nginx installed on host?
Check if nginx is available in $PATH
```
which nginx
```
If nginx is installed, but from the previous steps you’ve verified that it’s not running, then you can safely ignore it. We will use a different (RTMP enabled) nginx build for xplex .
You can also choose to remove it if you’re sure it’ll not be needed (not recommended).
