How to rewrite nginx to proxy?

Question

New to rewrites. Running 2 services on my host:

  location /{
      #this works fine
      proxy_pass http://myMainServiceIp/;    
   }

   location /wordpress{
      #works but redirects to http://example.com/wp-admin/install.php
      #rather than http://example.com/blog/wp-admin/install.php
      proxy_pass http://wordpressServiceIp/;    
   }

How can I forward /blog/*params*/*etc*/*etc* to my wordpress service correctly?

Answer 1

There are two separate but related issues. The location needs a trailing / so that proxy_pass can alias the URIs correctly.

location /blog/ {
    proxy_pass http://wordpressServiceIp/;    
}
location = /blog {
    rewrite ^ /blog/ last;
}

I have added the second location block to handle the one special case.

The second issue is HOME and SITEURL needs to point to http://example.com/blog/ . See this document for more.
