Hello. I'm a bit new to this. I have a droplet of ruby application. Ubuntu 12.1, nginx + unicorn. I want to create a subdomain that calls for a different directory. domain.net -> /home/rails sub.domain.net -> /var/www/sub/public_html I've followed these two tutorial: https://www.digitalocean.com/community/articles/how-to-set-up-and-test-dns-subdomains-with-digitalocean-s-dns-panel https://digitalocean.com/community/articles/how-to-set-up-nginx-server-blocks-virtual-hosts-on-ubuntu-14-04-lts My zone file is: @ IN A xxx.xxx.xxx.xxx blog IN A xxx.xxx.xxx.xxx * CNAME @ *.sub CNAME sub.domain.net. My "default" nginx file is: server { listen 80; root /home/rails/public; server_name www.domain.net domain.net; index index.htm index.html; location / { try_files $uri/index.html $uri.html $uri @app; } # location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mp3|flv|mpeg|avi)$ { location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ { try_files $uri @app; } location @app { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://app_server; } } and my "sub.domain.net" file is: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; root /var/www/blog/public_html; index index.html index.htm index.php; server_name blog.minhn.net; location / { try_files $uri $uri/ =404; } } Both have symbolic links in /etc/nginx/sites-enabled However if I go to sub.domain.net it shows domain.net content. I'm not sure what I'm missing. Thanks.
