====== NGINX ======

===== Basics =====

Reload configuration inside docker:

<code>
docker exec -ti nginxcontainer nginx -s reload
</code>

===== Example rules =====

==== Deny all requests that contain "wp-cron.php" anywhere ====
<code>
  location ~ wp-cron.php? {
      deny all;
      access_log off;
      log_not_found off;
      return 444;
  }
</code>
===== Enable sites =====
<code>
$ ln -s /etc/nginx/sites-available/seximes /etc/nginx/sites-enabled/
$ service nginx restart
</code>
===== NGINX + PHP =====
Install the dependences:

''sudo apt-get install php5-common php5-cli php5-fpm''

Install nginx:

''sudo apt-get install nginx''

Start nginx:

''sudo service nginx start''

Test that it's working (should see "Welcome to nginx!")

''sudo service nginx stop''

In your nginx site configuration (/etc/nginx/sites-available/default), uncomment the lines in the server {} section starting with ''listen for ipv4 / ipv6 both.''

scroll down to where it says ''location ~ .php {'' and uncomment lines so it looks like this:

<code>
location ~ \.php$ {
  fastcgi_split_path_info ^(.+\.php)(/.+)$;
  fastcgi_pass unix:/var/run/php5-fpm.sock;
  fastcgi_index index.php;
  include fastcgi_params;
}
</code>
''sudo service php5-fpm restart 

sudo service nginx restart''

Your default web root is located at ''/usr/share/nginx/www''

To install mysql: ''sudo apt-get install mysql-server php5-mysql''

==== Note ====
:?: At this point I do not know if this works for a 502 Bad Gateway error but...
<code>
fastcgi_buffer_size 128k;
fastcgi_buffers 8 128k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
</code>

==== Example for php7 ====

You have to ensure that php7 is working:
<code>
service --status-all
service php7.0-fpm status
</code>

You can put a ''check.php'' file on your site:
<code>
<?php phpinfo(); ?>
</code>

<code>
server {
  server_name mantis.codi.coop;
  root /srv/mantis;

  location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;

        fastcgi_buffer_size 128k;
        fastcgi_buffers 8 128k;
        fastcgi_busy_buffers_size 128k;
        fastcgi_temp_file_write_size 128k;
    }

}
</code>
===== Notes =====
==== With wordpress ====
=== Accept post name as permalink ===
In the ''server'' section inside the configuration part:
<code>
# unless the request is for a valid file, send to bootstrap
if (!-e $request_filename)
{
   rewrite ^(.+)$ /index.php?q=$1 last;
}
</code>

==== Redirect to Flask app (in Gunicorn) ====
<code>
server {
        listen 80;
        listen [::]:80;
        server_name alfred.is-a-rockstar.com;
        location / {
                proxy_pass http://127.0.0.1:5000;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

</code>

==== Redirect www to another ====
<code>
# /etc/nginx/sites-available/exploreflask.com

# Redirect www.exploreflask.com to exploreflask.com
server {
        server_name www.exploreflask.com;
        rewrite ^ http://exploreflask.com/ permanent;
}

# Handle requests to exploreflask.com on port 80
server {
        listen 80;
        server_name exploreflask.com;

                # Handle all locations
        location / {
                        # Pass the request to Gunicorn
                proxy_pass http://127.0.0.1:8000;

                # Set some HTTP headers so that our app knows where the
                # request really came from
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}
</code>
==== Having several hosts ====
You can have several "server", for example:
<code>
server {
        listen 80;
        listen [::]:80;
        server_name alfred.is-a-rockstar.com;
        location / {
                proxy_pass http://127.0.0.1:5000;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

</code>
and
<code>
server {
	listen 80;
	listen [::]:80;

	root /var/www/seximes;
	index index.html index.htm;

	server_name seximes.cat;

	location / {
		try_files $uri $uri/ =404;
	}
}
</code>

==== Example reverse proxy configuration ====
<code>
server {
    server_name wiki.sir.gtd;
    location / {
        proxy_pass http://dokuwiki:80;
        proxy_set_header Host $host;
        proxy_set_header Accept-Encoding "";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_buffering off;
    }

    listen 80;
}
