How to Install Nginx on RHEL 7/ Redhat

by default, redhat yum repository will provide you nginx, so you can install nginx on redhat or rhel 7 with yum install command.

sudo yum install nginx -y

Verify Nginx Status

after installing nginx on your rhel 7 or Redhat server, verify is nginx running or not by using status command.

systemctl status nginx

Here in my case nginx is not running so lets start the nginx service.

Start Nginx Service

start the nginx service with start command.

systemctl start nginx

Add Nginx Ports To Firewall

by default nginx is running port 80 for http and port 443 for https access.

if you are using firewalld in your machine then add nginx ports to this firewalld using below commands.

sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Note: if you are using aws ec2 instances open 80,443 ports in inbound rules in security groups

Access Nginx in Browser:

you can access nginx webpage by entering Public IP address of your machine in the browser.

enter http://ip OR http://public_ip.
