How to Install Nginx on CentOS Stream 9

To install Nginx on CentOS Stream 9, follow the detailed steps below.

Step 1 : To begin, update your system to ensure you have the latest packages.

sudo dnf update

Step 2 : Install Nginx using the package manager.

sudo dnf install nginx

Step 3 : Confirm the installed Nginx version.

nginx -v

Step 4 : Enable and start the Nginx service.

sudo systemctl enable nginx --now

Step 5 : Check the status of the Nginx service to ensure it is running.

sudo systemctl status nginx

Step 6 : Allow HTTP (port 80) and HTTPS (port 443) traffic through the firewall.

sudo firewall-cmd --add-service=http --add-service=https --permanent

Reload the firewall to apply changes.

sudo firewall-cmd --reload

Step 7 : Create Nginx configuration for example

sudo nano /etc/nginx/conf.d/example.com.conf

Inside the configuration file, add the server block settings along with a location block to specify the document root and index file.

server {
    listen 80;

    server_name example.com www.example.com;

    root /var/www/html/example.com;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

Step 8 : Create index.html file for example.com

sudo mkdir -p /var/www/html/example.com
sudo nano /var/www/html/example.com/index.html

Inside the index.html file, add some basic HTML content, for example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Welcome to example.com</title>
</head>
<body>
    <h1>Hello, this is your Nginx server for example.com!</h1>
</body>
</html>

Step 9 : If SELinux is enabled, set the appropriate context.

sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/example.com(/.*)?"
sudo restorecon -Rv /var/www/html/example.com

Step 10 : Test the Nginx configuration for syntax errors.

sudo nginx -t

Step 11 : Restart Nginx to apply the changes.

sudo systemctl restart nginx

Step 12 : Open a web browser and enter example.com to verify the successful installation of Nginx.

Congratulations! You have successfully completed the detailed installation and configuration of Nginx on CentOS Stream 9.
