How to put Etherpad Lite behind a reverse Proxy

Feel free to add your own config examples.

node-https (without proxy)

If you want a secure SSL connection to your Etherpad, you can also use a native Node https server, see https://github.com/ether/etherpad-lite/pull/1202 .

Creating Certificate Authorities and self-signed SSL certificates: http://web.archive.org/web/20110704035103/http://www.tc.umn.edu/~brams006/selfsign.html

`http-proxy`

Accept https:// encrypted traffic and force http:// to https://

Simple proxy to accept https traffic and proxy to port 9001 and redirect http:// traffic dynamically to become https.

Includes default paths to letsencrypt cert files (created by running certbot certonly --standalone -d yourdomain.com after installing certbot).

const fs = require('fs');
const http = require('http');
const httpProxy = require('http-proxy');

//
// Create a HTTP proxy server
//
const targetPort = 9001;

httpProxy.createServer({
    target: {
        host: 'localhost',
        port: targetPort,
    },
    ssl: {
        key: fs.readFileSync('/etc/letsencrypt/live/yourdomain.com/privkey.pem', 'utf8'),
        cert: fs.readFileSync('/etc/letsencrypt/live/yourdomain.com/cert.pem', 'utf8'),
    },
}).listen(443);

http.createServer(function (req, res) {
    res.writeHead(301, { "Location": "https://" + req.headers['host'] + req.url });
    res.end();
}).listen(80);

console.log('Now proxying port 443 → http://0.0.0.0:'+targetPort +' and redirecting port 80 to port 443');

node-http-proxy

Simple example proxy server implemented in node.js with node-http-proxy. This example proxies on port 80 and 443. The port 80 proxy proxies to port 81 (where Apache is listening), and the port 443 proxy connects to Etherpad on port 9001.

var fs = require('fs'),
http = require('http'),
https = require('https'),
httpProxy = require('http-proxy');

//
// Create a HTTP proxy server
//
var regular_proxy = httpProxy.createServer(81, 'localhost').listen(80);

var routes_json = {
"server.org/pad": "127.0.0.1:9001",
".*": "127.0.0.1:81"
};

//
// Create a HTTPS proxy server
//
var ssl_proxy = httpProxy.createServer({
    router: routes_json,
    https: {
        key: fs.readFileSync('/etc/apache2/ssl/server.org.key', 'utf8'),
        cert: fs.readFileSync('/etc/apache2/ssl/server.org.crt', 'utf8'),
        ca: fs.readFileSync('/etc/apache2/ssl/gd_bundle.crt', 'utf8')
    },
}).listen(443);

Apache

General Apache security advice [added 2011-11-26]:
Apache users should carefully check their version, and generally check their conf files for a potential security issue as described in http://www.h-online.com/open/news/item/Apache-patch-patches-poorly-1385107.html which could allow access to internal systems if the reverse proxy rules are configured incorrectly. The following configuration appears to be correct and safe, as the proxy statements ends with a closing "/".

To implement these configs place them in your Apache configuration folder, usually /etc/httpd/conf/ -- If this is new to you then you should read up on Apache virtual hosts and configuration. You will need to activate (maybe after having installed) the mod_proxy, mod_proxy_http, mod_headers, proxy_wstunnel, mod_deflate and mod_rewrite Apache modules.

Very basic rewrite

Add this to allow nice urls, such as "https://etherpad.example.org/padname"

In case you are using plugins, don't forget to add to this list the RewriteCond needed for each one that use new link access. Some examples (not an exhaustive list. Check your apache logs in case of problems with a plugin):

ep_list_pads plugin:

RewriteCond %{REQUEST_URI} !^/list/
RewriteCond %{REQUEST_URI} !^/public/

ep_historicalsearch plugin:

RewriteCond %{REQUEST_URI} !^/historicalSearch

ep_fileupload plugin:

RewriteCond %{REQUEST_URI} !^/fileUpload/
RewriteCond %{REQUEST_URI} !^/up/

HAproxy

During the setup phase, HAProxy can work in HTTP mode, processing layer 7 information. It detects automatically the Connection: Upgrade exchange and is ready to switch to tunnel mode if the upgrade negotiation succeeds. During this phase, there are 3 timeouts involved:

timeout client: client inactivity
timeout connect: allowed TCP connection establishment time
timeout server: allowed time to the server to process the request

If everything goes well, the websocket is established, then HAProxy fails over to tunnel mode, no data is analyzed anymore (and anyway, websocket does not speak HTTP). There is a single timeout involved:

timeout tunnel: take precedence over client and server timeout

timeout connect is not used since the TCP connection is already established 🙂

Lighttpd

Simple Reverse Proxy

$HTTP["host"] =~ "^example.com$" {
  proxy.server  = ( "" => ( (
                              "host" => "127.0.0.1",
                              "port" => 9001
                            ) )
                  )
}

If you use more than one server behind lighty (you can add more server - look at the lighty docs linked above) you have to use the hash balancer. So for any request the same server will be used. But remember: If you restart lighty this probably does not work anymore. (TODO: add synchronization in etherpad-lite)

You need to download and install Ionics Isapi Rewrite Filter, when installing select the site you wish to use to reverse proxy. Browse to your websites root and create a file called IIRF.ini

Add this to the file:

RewriteBase OFF
ProxyPass          ^/pad/(.*)$   http://etherpad.internal.example.org:9001/
ProxyPass          ^/p/(.*)$   http://etherpad.internal.example.org:9001/p/$1
ProxyPass          ^/static/(.*)$   http://etherpad.internal.example.org:9001/static/$1
ProxyPass          ^/pluginfw/(.*)$   http://etherpad.internal.example.org:9001/pluginfw/$1
ProxyPass          ^/javascripts/(.*)$   http://etherpad.internal.example.org:9001/javascripts/$1

Stop and Start the IIS site.

IIS 7.0

You need to install the Application Request Routing module to IIS first, using the Web platform installer. This is fairly straightforward to do: Open the Webplattform-Installer, e.g. by clicking your server in the server management console under Roles / Webserver (IIS) / Internet Information Services (I got this in German, so don't get confused when the terms are a little different on your installation - I'm trying to translate this back to English; if you follow these instructions on an English installation it would be nice if you could correct any wrong terms). It's in the Management section (probably the lowest entry in the list).

Here you will find "Application Request Routing" (currently 2.5). Click "Add" and then "Install". Wait.

Once the installation is complete, you'll find "Serverfarms" below "Sites" in your server. Add one with the name of your EtherPad Lite installation. Make sure to enter the correct ports under "Extended Settings" (I'm using 9001 for both httpPort and httpsPort).

Now be careful to not have the console create any default routing settings (that might route any request to any of the sites hosted on your machine to EtherPad Lite). Double click your newly created server farm, then double click "Routing Rules". Under "Advanced Routing", click "URL Rewrite..."

Make sure there are no rules (if any were created, delete them). Create a new empty rule.

You can almost follow the instructions from here:

http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx

BUT: If you have multiple sites hosted on that IIS, make sure to add conditions to check against the hostname. Use {HTTP_HOST} as "entry", "matches pattern" and your full domain for EtherPad Lite as pattern.

Finally, in action, I used "forward to server farm" with schema "http://", Serverfarm "the one I created before" and Path "/{R:0}". That's it.

For me, this worked both with HTTP and HTTPS.

The important part is the TimeOut value, as otherwise Pound will fail with 500 - Internal Server Error.
