Nginx: Rewrite from base domain to a sub directory

Question

I have a blog hosted at http://site.com/blog.

How do I instruct nginx to rewrite requests from site.com to site.com/blog?

This should not be permanent.

Answer 1

location = / {
    rewrite ^ http://site.com/blog/ redirect;
}

This'll just do requests specifically for the root. If you need to catch everything (redirect http://site.com/somearticle/something.html to http://site.com/blog/somearticle/something.html), then you'll need something more involved:

location /blog/ {
    # Empty; this is just here to avoid redirecting for this location,
    # though you might already have some config in a block like this.
}
location / {
    rewrite ^/(.*)$ http://site.com/blog/$1 redirect;
}
