Nginx running Ghost: add public www location? - nginx

Question

I'm trying to upload a bunch of html and image files to my Nginx webserver which is running Ghost (the blogging platform) lets call it ghost-blog.com. Ghost runs perfectly fine, but additionaly I want serve other files and folders under the same domain e.g. ghost-blog.com/text.html and ghost-blog.com/subfolder/index.html.
After spending some time googling for an answer it seems I've bumped into something "new". I am aware I need to make changes to the /etc/nginx/sites-available/default file. What I don't know is what to add/edit so that
I create a /some/random/public folder public
This does not conflict with Ghost which is already serving content, specially the default index index.html index.htm files.
My current /etc/nginx/sites-available/default config file looks like this:
server {
listen 80;
server_name www.ghost-blog.com;
rewrite ^/(.*) http://ghost-blog.com/$1 permanent;
}
server {
root /usr/share/nginx/www;
index index.html index.htm;
server_name localhost;
location / {
try_files $uri $uri/ /index.html;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}
}
Any suggestions on how I could go around creating a /public folder serving other files and sub-folders?

Answer 1

server {
listen 80;
server_name www.ghost-blog.com/subfolder;
rewrite ^/(.*) http://ghost-blog.com/subfolder/$1 permanent;
}
server {
root /usr/share/nginx/www/NEWSITEFOLDER;
index index.html index.htm;
location / {
try_files $uri $uri/ /index.html;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}
}
then in ssh you need to make this directory to run the new ghost blog from
/usr/share/nginx/www/NEWSITEFOLDER;
so run command
mkdir /usr/share/nginx/www/NEWSITEFOLDER;
