Crow/docs/guides/proxies.md

You can set Crow up behind any HTTP proxy of your liking, but we will be focusing specifically on 2 of the most popular web server software solutions, Apache2 and Nginx.

A reverse proxy allows you to use Crow without exposing it directly to the internet. It also allows you to, for example, have crow run on a certain specific domain name, subdomain, or even a path, such as domain.abc/crow.

We advise that you set crow up behind some form of reverse proxy if you plan on running a production Crow server that isn't local.

!!! warning "SSL"

When using a proxy, make sure that you **do not** compile Crow with SSL enabled. SSL should be handled by the proxy.

##Apache2

Assuming you have both Apache2 and the modules proxy, proxy_http, proxy_html (if you plan on serving html pages), and proxy_wstunnel (if you plan on using websockets). You will need to enable those modules, which you can do using the following commands:

a2enmod proxy
a2enmod proxy_http
a2enmod proxy_html
a2enmod proxy_wstunnel

Next up you'll need to change your configuration (default is /etc/apache2/sites-enabled/000-default.conf) and add the following lines (replace localhost and 40080 with the address and port you defined for your Crow App):

ProxyPass / http://localhost:40080
ProxyPassReverse / http://localhost:40080

If you want crow to run in a subdirectory (such as domain.abc/crow) you can use the location tag:

<Location "/crow">

	ProxyPass http://localhost:40080
	
	ProxyPassReverse http://localhost:40080

</Location>

!!! note

If you're using an Arch Linux based OS. You will have to access `/etc/httpd/conf/httpd.conf` to enable modules and change configuration

##Nginx

Setting Nginx up is slightly simpler than Apache, all you need is the Nginx package itself. Once you've installed it, go to the configuration file (usually a .conf file located in /etc/nginx) and add the following lines to your server section (replace localhost and 40080 with the address and port you defined for your Crow App):

location / {
    proxy_pass http://localhost:40080/;
    proxy_http_version 1.1;
}

Remember to remove or comment out any existing location / section.

Alternatively, if you want to use a subdirectory, you can simply change the location parameter as such:

location /crow/ {
    proxy_pass http://localhost:40080/;
    proxy_http_version 1.1;
}
