Nginx - how to move the domain.com/blog/ URL to a separate directory?

Question

linux

Good afternoon colleagues.
I have one site, domain.com which is located at /home/domain.com/www
everything works fine.
Now it's time to create a blog for this site.
I created /home/domain.com.blog/www and now I'm trying to set up NGINX to work with this folder.
Created a rule:

location /blog {
  
  root /home/domain.com.blog/www;
  index index.php;
  
  location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
  }
}

Wordpress started to load, but static files were not loaded, I had to add a separate one correctly for static files.

location /blog {
  
  root /home/domain.com.blog/www;
  index index.php;
  
  location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
  }
  
  location ~* \.(gif|jpg|jpeg|png|ico|bmp|wmv|3gp|avi|mpg|mpeg|mp4|flv|mp3|mid|js|css|woff|exe|eot|svg|ttf)$ {
    root /home/domain.com.blog/www;
    expires 14d;
    add_header Pragma public;
    add_header Cache-Control "public, must-revalidate, proxy-revalidate";
    access_log off;
  }
}

After that, static files started loading, the last problem that I could not overcome was links.
https://domain.com/blog/2015/08/05/hello-world/
I would be very grateful if you tell me how to make Wordpress links work.
Here is the error.log

2015/08/13 15:10:59 [error] 1127#0: *53 "/home/domain.com.blog/www/blog/2015/08/05/hello-world/index.php" is not found (2: No such file or directory), client: 81.21.83.210, server: domain.com, request: "GET /blog/2015/08/05/hello-world/ HTTP/1.1", host: "domain.com"

I want to note that Wordpress is installed in the directory: home/domain.com.blog/www/blog/
The only thing that confuses me in error.log is where index.php comes from at the end of the URL

server {
    listen 443;
    root /home/domain.com/www;
    index index.php; 
    server_name domain.com;
  
  location ~* \.(gif|jpg|jpeg|png|ico|bmp|wmv|3gp|avi|mpg|mpeg|mp4|flv|mp3|mid|js|css|woff|exe|eot|svg|ttf)$ {
    root /home/domain.com/www;
    expires 14d;
    add_header Pragma public;
    add_header Cache-Control "public, must-revalidate, proxy-revalidate";
    access_log off;
    log_not_found off;
  }
  
  
  location /admin {
    try_files $uri $uri/ /admin/index.php?/$request_uri;
        }

  location / {
    try_files $uri $uri/ /index.php?/$request_uri;
  }

  location ~ \.php$ {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
  }
}

I would be very grateful if you tell me how to get Wordpress on NGINX in a sub-directory.

From here
Try location /blog add try_files with wordpress rules. - there are a lot of articles.
There is simply no rule that if there is no file, then what address to trace to try
