Now that you have download the NSSM Zip file.  Go ahead and unzip that file and navigate to the folder that has win32 and win64 folders.  Depending on your Windows installation [More than likely 64bit] go into the correct folder.  Copy the nssm.exe file into C:/windows/system32/

Open up the file that you copied/renamed to php.ini

You will need to un-comment the following lines:

;extension_dir = "ext"
;extension=php_curl.dll
;extension=php_mbstring.dll
;extension=php_mysqli.dll
;extension=php_openssl.dll
;extension=php_pdo_mysql.dll
;extension=php_pdo_sqlite.dll
;extension=php_sqlite3.dll

If you don’t know how to un-comment, just delete the ; symbol infront of each line.

Then save the file.

Open up the nginx.conf file that is located at C:/nginx/conf/nginx.conf

Here is a brief overview of this page:

listen 80; This is the port that NGINX will listen on
server_name localhost; This is where you will put any domain name that you own
location / { root html; index index.html index.htm; } This is where NGINX will serve the website from

First thing we need to do is edit this line and add index.php:
index index.html index.htm;edit line to index index.php index.html index.htm;
Next we need to enable the php block so nginx knows where to send those files to process:

#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}

change line to

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

Notice that we changed /scripts to $document_rootwhich will allow nginx to know where to pull files from
