I’m trying to install Wordpress on a LEMP Stack on CentOS 8, but I don’t know what I’m doing wrong because it only shows the default page of NGINX

Code on /etc/nginx/conf.d/wordpress.conf

upstream php {
    server unix:/tmp/php-cgi.socket;
        server 127.0.0.1:9000;
}

server {
        server_name sitename;
        root /var/www/html/public_html/;
        index index.php;

        location = /favicon.ico {
                log_not_found off;
                access_log off;
        }

    location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
        }

    location / {
                # This is cool because no php is touched for static content.
                # include the "?$args" part so non-default permalinks doesn't break when using query string
                try_files $uri $uri/ /index.php?$args;
        }

    location ~ \.php$ {
                #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
                include fastcgi_params;
                fastcgi_intercept_errors on;
                fastcgi_pass php;
                #The following parameter can be also included in fastcgi_params file
                fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
                expires max;
                log_not_found off;
        }
}
