Add new domain to nginx, then you need to restart nginx!

addDomain.py

import sys
import os

print "Create New Domain!"

dom = raw_input("DomainName: ")
print "Creating domain", dom

print "Creating folder /var/www/" + dom + '/html'

os.system("mkdir /var/www/" + dom)
os.system("mkdir /var/www/" + dom + '/html')
os.system("chown -R www-data:www-data /var/www/" + dom )

print "Creating site-available"

fileName = dom

os.system("echo 'server {' >> " + fileName)
os.system("echo '    listen 80;' >> " + fileName)
os.system("echo '    server_name  www."+dom+";' >> " + fileName)
os.system("echo '    return 302 http://"+dom+"$request_uri;' >> " + fileName)
os.system("echo '}' >> " + fileName)
os.system("echo 'server {' >> " + fileName)
os.system("echo '    root /var/www/"+dom+"/html;' >> " + fileName)
os.system("echo '    index index.html index.php index.htm;' >> " + fileName)
os.system("echo '    server_name "+dom+";' >> " + fileName)
os.system("echo '    location / {' >> " + fileName)
os.system("echo '       try_files $uri $uri/ /index.php?q=$uri&$args;' >> " + fileName)
os.system("echo '    }' >> " + fileName)
os.system("echo '    error_page 404 /404.html;' >> " + fileName)
os.system("echo '    error_page 500 502 503 504 /50x.html;' >> " + fileName)
os.system("echo '    location = /50x.html {' >> " + fileName)
os.system("echo '       root /usr/share/nginx/www;' >> " + fileName)
os.system("echo '    }' >> " + fileName)
os.system("echo '    location ~ \.php$ {' >> " + fileName)
os.system("echo '        fastcgi_pass unix:/var/run/php5-fpm.sock;' >> " + fileName)
os.system("echo '        fastcgi_index index.php;' >> " + fileName)
os.system("echo '        include fastcgi_params;' >> " + fileName)
os.system("echo '    }' >> " + fileName)
os.system("echo '}' >> " + fileName)


print 'Moving to site-available'
os.system("mv " + dom + " /etc/nginx/sites-available/")

print 'Link'
os.system("sudo ln -s /etc/nginx/sites-available/"+dom+" /etc/nginx/sites-enabled/"+dom)

print 'DONE!'

I know it would be much better to make a bash script, but it's ok! :)
