Nginx: multiple websites on one server

nginxUbuntuwebsite

Ive got three websites I wish to have served from one server. The server is an Ubuntu droplet on digitalocean, the websites are in my home directory in ~/site1 ~/site2 and ~/site3. I have nginx with stock nginx.conf. I have three files in sites-available (site1.com site2.com & site3.com) In each file they have the following structure according to each respective site:

server {
    listen 80;
    listen [::]:80;
    root /home/user/site1;
    index.html
    server_name site1.com *.site1.com
    return 301 https://$server_name$request_uri;
}

The three files are symlinked in sites-enabled and in both sites-enabled and sites-available the default file is deleted. Also, the site 2 has default_server appended to the end of the two listen lines

Nginx starts fine with no errors:

$ sudo nginx -t
$ service nginx restart

But when I go to the each respective website, they all direct me back the default_server site2 website. The website domains were bought on godaddy.com, and all point towards this server's IP.

How can I solve this problem so each website gets redirected properly? I'm fairly new to this side of things and self taught, so if at all possible a little explanation would help a lot.

The following places helped me get to the above:

https://stackoverflow.com/questions/11693135/multiple-websites-on-nginx-sites-available

EDIT:
The extra things I have tried now are:

Removed the return 301 https://$server_name$request_uri; line from each files server block.
Cleared the cache from multiple browsers and devices.
Changed the root path to /var/www/html/site1-2-3
Adding SERVERIP site1.com, SERVERIP site2.com, SERVERIP site3.com to /etc/hosts

Still no change in behavior and still redirecting to the default server

EDIT2:
The following are the full config files:

        server_name site1.com *.site1.com;

EDIT3
I noticed that the version of nginx was 1.10.3, which is not the most current, so i removed it with apt-get remove purge etc. Then I downloaded and built from source 1.12.0 with the whole ./configure, make, make install process, it depended on a few other packages, but once done and server blocks in place, included in nginx.conf, I still have the same problem, redirecting to the default_server.

I'm not confident this will help, but it's worth a shot. It's too difficult to format in a comment. If it doesn't work, tell me, I'll think some more or delete the answer.

It's basically a super simple config with nothing special.

server {
    server_name site1.com www.site1.com;
    listen 80;

    root /home/deploy/site1;
    try_files $uri $uri/ =404;

    index index.html index.htm index.nginx-debian.html;
}

Also, if it doesn't work, move your default_server statement to another server then check all three sites. I just want to make sure it changes as expected.

Nginx PHP files downloading instead of executing

Had the same issue!

Found the answer here, http://www.ceus-now.com/nginx-password-protect-directory-downloads-source-code/

Because we are adding ^~ we are leaving behind some other settings (not sure why we need to add this but it was the only way to get it to actually pull up the authentication :( )

include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/lib/php5-fpm/web11.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;

I tried various combinations to see what was/not needed and each line is needed. I wish I understood these things better.

UPDATE: July 27th 2016:

So I did some reading and finally understand why we have this issue.

In short when we install FastCGI and php-fpm it creates a directive in the nginx server files (which file depends on your server install).

So in mine I have the following...

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
    #
    #       # With php7.0-cgi alone:
    #       fastcgi_pass 127.0.0.1:9000;
    #       # With php7.0-fpm:
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;

As you will notice these directives are in location / and not in the global settings. Since we want to secure a particular folder these directives are not inherited. Therefore, we need to declare it again.

If we wanted to follow the DRY ("Don't Repeat Yourself") principle, then we would declare the PHP-fpm and FastCGI in the global settings. We can do this by moving it to below (example, but it just needs to be outside of location directive). Here is an example.

root /var/www/html;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;

Hope this helps. I realized the above by reading https://www.digitalocean.com/community/tutorials/understanding-and-implementing-fastcgi-proxying-in-nginx

Disclaimer: I am no pro so if you see mistakes be nice and just let me know and I will hopefully update.

Nginx – CodeIgniter nginx rewrite rules for i8ln URL’s

Found a much simpler solution. Following what CodeIgniter does behind the scenes for clean URL's; in Apache this rewrite works by sending each request as http://example.com/index.php?/controller/method which is then processed by CodeIgniter so your config.php should look like

$config['base_url'] = 'http://example.com'
$config['index_page'] = '';
$config['uri_protocol'] = 'REQUEST_URI';

To achieve the same in nginx you'd have to rewrite each request in identical way. Fine tuned my nginx configuration with:

location /example {

    root /var/www/html/;
    index index.php;

    location ~ ^/example/(.+\.php)$ {

        fastcgi_buffer_size 128k;
        fastcgi_buffers 256 4k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_temp_file_write_size 256k;
        root /var/www/html/;
        include /etc/nginx/snippets/fastcgi-php.conf;
    }

    location ~* ^/example/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)) {
        root /var/www/html/;
    }

    # Enforce SSL
    if ($scheme = http) {
        return 301 https://$host$request_uri;
    }

    # CI rewrite rules
    if ($host ~* ^www\.(.*)) {
        set $host_without_www $1;
        rewrite ^/(.*)$ $scheme://$host_without_www/$1 permanent;
    }

    if ($request_uri ~* ^(/example/(US|EU|INT)/(en|de)(.*))?$) {
        rewrite ^/(.*)$ /example/index.php?/$1 last;
    }

    if ($request_uri ~* ^(/example/(US|EU|INT)/(en|de)/(.*))?$) {
        rewrite ^/(.*)$ /example/index.php?/$1 last;
    }

    # catch all
    error_page 404 /index.php;
}

The missing link existed in nginx rewrite debug log so if you want to know about your rewrite rules and whether they are matched against your rule set add this to your nginx configuration:

server{
  ...
  rewrite_log on;
  error_log /var/log/nginx/error.log info;
  ...
}

And nginx will give you each request log with a match or no match against your PCRE regex. From here on you can tweak your configuration. I had to prepend path (directory) example in nginx configuration file for rewrite rules to work as expected.
