Nginx downloads PHP instead of executing it

I recently set up an Ubuntu Server with Nginx. Now I want to install phpBB on it. But it seems like I fail. The index.html in the public_html folder I had before, worked just fine. But since I want phpBB3, I excrated the folder to my public_html folder. So now I have the folder "phpBB3".
But if I go to http:// mydomain.com/phpBB3 it simply tries to download a "octet stream" file. I opened the file in notepad and it turned out to be the php script. Here are my config files + location:

/etc/nginx/sites-available/default

Also I edited /etc/php5/fpm/php.ini and made sure cgi.fix_pathinfo is set to 0
[Note: I made a space after every "http" because the forum wont allow me to post it]

Can anyone help me please?

 

Seriously? No one can help?

 

I have never used nginx. Usually, some sort of directive must be made in a web server's configuration file to process .php files with the PHP Hander. What type of PHP install do you have? You did install PHP, right? If you Google, you should be able to find an answer to your question. And when you do, you should report back with the solution so others can learn as well.

 

It does not appear that you have Nginx configured to use PHP, this is part of your config file posted above, note the lines are all commented out:

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# # With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
# # With php5-fpm:
# fastcgi_pass unix:/var/run/php5-fpm.sock;
# fastcgi_index index.php;
# include fastcgi_params;
#}

Code (markup):

Do you know if you have fastcgi configured to serve PHP? Are you using any control panel for this server?

I found it out. The problem wasn't the PHP part itself (it was not commented out) but the problem was that the file

/etc/nginx/sites-available/default

Code (markup):

was the wrong config. I had to apply all changes to

/etc/nginx/sites-available/mydomain.com

Code (markup):

aswell for it to work.
