nginx not listening to port 80

I've just installed a Ubuntu 12.04 server and nginx 1.2.7, removed `default` from sites-enabled and added my own file into `sites-available` and symlink at `sites-enabled`. Then restarted nginx. **Problem:** However going to the URL does not load the site. `netstat -nlp | grep nginx` and `netstat -nlp | grep 80` both returns no results! `lsof -i :80` also returns nothing. A `dig` from another server returns the correct ip address so it shouldn't be a DNS problem. I was able to connect to apache which I have now stopped its service. nginx logs also show nothing. How should I troubleshoot this problem? **/etc/nginx/site-available/mysite.com** server { listen 80; server_name www.mysite.com mysite.com *.mysite.com; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; root /var/www/mysite/public; index index.php index.html; location / { try_files $uri $uri/ /index.php?$args ; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_read_timeout 300; } }
