Nginx and Jekyll: serving in a subdomain - nginx

Question

I'm currently stuck in configuring Jekyll and nginx to work together on a VPS.
Essentially, I set up everything and a git hook from my local machine to the VPS.
Here is my nginx config file:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www;
index index.php index.html index.htm;
server_name server_ip;
location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
server {
listen 80;
server_name server_ip/blog;
location / {
root /var/www/blog;
index index.html index.htm;
}
}
Ideally, what I'd like is to serve what is in /var/www/blog at blog.domain.example, or blog.server_ip at the moment.
However, when jekyll build runs, the URLs are all wrong. I can see index.html at server_ip/blog, but the /blog/ bit in the URL is not replicated in the links on the Jekyll page.
For example, a post should live at server_ip/blog/2015/04/07/title, but the URL I'm given is server_ip/2015/04/07/title. Same goes for the CSS files, and images as well.
Thanks very much for your help.

Answer 1

You have to set baseurl: "/blog"
And link to posts like this <a href="{{site.baseurl}}{{post.url}}>....
And generaly use {{site.baseurl}} to built any url.
