NGINX is a high performance and modular server that you can use, for example, as a:

Red Hat uses Application Streams to provide different versions of NGINX. You can do the following:

Using the default configuration, NGINX runs as a web server on port 80 and provides content from the /usr/share/nginx/html/ directory.

Prerequisites

Procedure

Install the nginx package:
```
# dnf install nginx
```
Open the ports on which NGINX should provide its service in the firewall. For example, to open the default ports for HTTP (port 80) and HTTPS (port 443) in firewalld, enter:
```
# firewall-cmd --permanent --add-port={80/tcp,443/tcp}
# firewall-cmd --reload
```
Enable the nginx service to start automatically when the system boots:
```
# systemctl enable nginx
```
Optional: Start the nginx service:
```
# systemctl start nginx
```
If you do not want to use the default configuration, skip this step, and configure NGINX accordingly before you start the service.

Verification

Use the dnf utility to verify that the nginx package is installed:

# dnf list installed nginx
Installed Packages
nginx.x86_64    1:1.14.1-9.module+el8.0.0+4108+af250afe    @rhel-8-for-x86_64-appstream-rpms

Ensure that the ports on which NGINX should provide its service are opened in the firewalld:
```
# firewall-cmd --list-ports
80/tcp 443/tcp
```
Verify that the nginx service is enabled:
```
# systemctl is-enabled nginx
enabled
```
