Nginx Rewrite Does not Work Correctly - nginx

Question

I want to apply rewrite /author/xxx to /index.php?author_name=xxx
rewrite ^/author/(.*)/$ /index.php?author_name=$1;
When I apply code, browser url looks like that :
http://www.site-name.com/?author_name=xxx
I want url will look like :
http://www.site-name.com/author/xxx but it will rewrite index.php?author_name=xxx
Any idea to fix it?
My Nginx conf file is below :
server {
server_name site-name.com;
rewrite ^(.*) http://www.site-name.com$1 permanent;
listen 8080;
}
server {
listen 8080;
access_log off;
# access_log /home/www.site-name.com/logs/access_log;
error_log on;
# error_log /home/www.site-name.com/logs/error.log;
#add_header X-Frame-Options SAMEORIGIN;
#add_header X-Frame-Options "ALLOW-FROM https://www.site-name.xyz";
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
root /home/www.site-name.com/public_html;
include /etc/nginx/conf/ddos2.conf;
# include /etc/nginx/conf/cors.conf;
index index.php index.html index.htm;
server_name www.site-name.com;
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
rewrite ^/author/(.*)/$ /index.php?author_name=$1;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
#fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_connect_timeout 250;
fastcgi_send_timeout 250;
fastcgi_read_timeout 250;
fastcgi_buffer_size 256k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME /home/www.site-name.com/public_html$fastcgi_script_name;
}
include /etc/nginx/conf/drop.conf;
}

Your rewrite looks OK: From extern you can use /author/... and internally it will use index.php?....
I suppose you also want to redirect index.php?... to the nice path:
rewrite ^/author/([^/]*)/?$ /index.php?author_name=$1 break;
rewrite ^/index.php$ https://www.example.com/author/$arg_author_name/ redirect;
root /var/www/html/;
fastcgi_index index.php;
fastcgi_pass php;
include fastcgi_params;
