How to Set Up Nginx Server Blocks on AlmaLinux 10

To set up multiple websites on AlmaLinux 10 using Nginx server blocks, follow the steps below:

Step 1 : Check that Nginx is installed on your system:

nginx -v

If Nginx is not installed, install it before continuing.

Step 2 : Create the document root for example.com:

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

Create an index file:

sudo nano /var/www/html/example.com/index.html

Add sample content:

<h1>Welcome to example.com</h1>

Step 3 : Set the correct ownership and permissions:

sudo chown -R nginx:nginx /var/www/html/example.com
sudo chmod -R 755 /var/www/html/example.com

Step 4 : Create a configuration file for example.com:

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

Add the following configuration:

server {
    listen 80;
    server_name example.com www.example.com;

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

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

Save and exit the file.

Step 5 : If SELinux is enabled, apply the correct context:

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

Step 6 : Test the Nginx configuration:

sudo nginx -t

Step 7 : Restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 8 : Open a web browser and visit:

http://example.com

Congratulations! You have successfully set up an Nginx server block on AlmaLinux 10.
