+------------------------------------
-1. Install git if not already present:
+1. Install websocketd (latest stable release from http://websocketd.com/)
+
+.(Debian, Ubuntu)
[source,bash]
---------------------------------------------------------------------------
-apt-get install git-core
+cd /tmp
+wget 'https://github.com/joewalnes/websocketd/releases/download/v0.3.0/websocketd-0.3.0-linux_amd64.zip'

+sudo cp websocketd /usr/local/bin/
---------------------------------------------------------------------------
+
-2. Install the apache-websocket module:
+2. Run websocketd
++
+Choose option a or b, below.
++
+[NOTE]
+===========================================================================
+websocketd does not offer a configurable inactivity timeout, meaning
+websocket client connections will persist until each client disconnects
+or the service is restarted. However, a timeout can be achieved with
+the use of a proxy (option 'a' below). A proxy also allows websocketd
+to be exposed to web clients on port 443 instead of its internal port,
+which may simplify firewall configuration.
+===========================================================================
++
+a. Run websocketd as 'opensrf'
+
+[NOTE]
+===========================================================================
+This choice requires one of the proxy configurations mentioned below.

+
-3. Create the websocket Apache instance (more information about this in
- /usr/share/doc/apache2/README.multiple-instances)
+b. Run websocketd without a proxy
+
-.(Debian / Ubuntu Precise)
+.(Debian, Ubuntu)

---------------------------------------------------------------------------
+
+Optional: Using a web proxy (Apache 2.4 and above)
+--------------------------------------------------
+When the OpenSRF HTTP Translator runs behind a proxy, Apache must be
+configured to read the IP address of the originating client instead
+of the proxy IP address.
+
+1. Enable mod_remoteip
+
-.(Ubuntu Trusty)
[source,bash]
---------------------------------------------------------------------------
-sh /usr/share/doc/apache2/examples/setup-instance websockets
+sudo a2enmod remoteip
---------------------------------------------------------------------------
+
-4. Remove from the main apache instance
+2. Enable remote IP settings by uncommenting and modifying as needed the
+ Apache configuration variables starting with RemoteIP* in the sample Apache
+ configuration file opensrf.conf.
+
-[source,bash]
+3. Configure Apache to listen on port 7080 for HTTP and port 7443 for HTTPS
+ and ensure that it is not listening on ports 80 and 443, then restart Apache.
++
+4. If you didn't run `configure` with the `--with-websockets-port=443` option,
+ edit `<PREFIX>/javascript/opensrf_ws.js` and `<PREFIX>/javascript/opensrf_ws_shared.js`
+ and change
++
+[source, javascript]
---------------------------------------------------------------------------
-a2dismod websocket
+var WEBSOCKET_PORT_SSL = 7682;
---------------------------------------------------------------------------
+
-5. Copy into place the config files
+to
+
-.(Debian / Ubuntu Precise)
-[source,bash]
+[source, javascript]
---------------------------------------------------------------------------
-cp /home/opensrf/OpenSRF/examples/apache2/websockets/apache2.conf /etc/apache2-websockets/
+var WEBSOCKET_PORT_SSL = 443;
---------------------------------------------------------------------------
+
+
+Optional: Using NGINX as a proxy
+--------------------------------
+NGINX can be used to proxy HTTP, HTTPS, and WebSockets traffic. Among other
+reasons, this can be useful for Evergreen setups that want to have both
+HTTPS and secure WebSockets traffic both go through port 443 while using
+two Apache instances (one for the WebSockets gateway and one for the more
+memory-intensive TPAC pages).
+
+The following instructions are a guide for setting this up on Debian
+and Ubuntu systems, but expect general familiarity with various system
+administration and network tasks. The steps should be run as the *root*
+Linux account, and assume that you already followed the instructions
+for installing WebSockets support.
+
+1. Install NGINX if not already present:
+
-.(Ubuntu Trusty)
-[source,bash]
+[source, bash]
+---------------------------------------------------------------------------
+apt-get install nginx
---------------------------------------------------------------------------
-cp /home/opensrf/OpenSRF/examples/apache_24/websockets/apache2.conf /etc/apache2-websockets/
++
+2. Copy the example NGINX configuration file into place and remove default.
++
+[source, bash]
+---------------------------------------------------------------------------
+cd /path/to/opensrf-OSRFVERSION
+cp examples/nginx/osrf-ws-http-proxy /etc/nginx/sites-available/
+ln -s /etc/nginx/sites-available/osrf-ws-http-proxy /etc/nginx/sites-enabled/osrf-ws-http-proxy
+rm /etc/nginx/sites-enabled/default
---------------------------------------------------------------------------
+
-6. OPTIONAL: add these configuration variables to /etc/apache2-websockets/envvars
- and adjust as needed.
+3. Edit `/etc/nginx/sites-available/osrf-ws-http-proxy` to set the location
+ of the SSL certificate and private key.
+4. Generate a dhparam file in the directory specified in the nginx config.
+
+[source, bash]
---------------------------------------------------------------------------
-export OSRF_WEBSOCKET_IDLE_TIMEOUT=120
-export OSRF_WEBSOCKET_IDLE_CHECK_INTERVAL=5
-export OSRF_WEBSOCKET_CONFIG_FILE=/openils/conf/opensrf_core.xml
-export OSRF_WEBSOCKET_CONFIG_CTXT=gateway
-export OSRF_WEBSOCKET_MAX_REQUEST_WAIT_TIME=600
+# Default config stores dhparam.pem in the Apache2 ssl directory.
+openssl dhparam -out /etc/apache2/ssl/dhparam.pem 2048
---------------------------------------------------------------------------
+
- * IDLE_TIMEOUT specifies how long we will allow a client to stay connected
- while idle. A longer timeout means less network traffic (from fewer
- websocket CONNECT calls), but it also means more Apache processes are
- tied up doing nothing.
- * IDLE_CHECK_INTERVAL specifies how often we wake to check the idle status
- of the connected client.
- * MAX_REQUEST_WAIT_TIME is the maximum amount of time the gateway will
- wait before declaring a client as idle when there is a long-running
- outstanding request, yet no other activity is occurring. This is
- primarily a fail-safe to allow idle timeouts when one or more requests
- died on the server, and thus no response was ever delivered to the gateway.
- * CONFIG_FILE / CTXT are the standard opensrf core config options.
+5. Start NGINX
++
+[source, bash]
+---------------------------------------------------------------------------
+/etc/init.d/nginx start
+---------------------------------------------------------------------------
-7. Before you can start websockets, you must install a valid SSL certificate
- in `/etc/apache2/ssl/`. It is possible, but not recommended, to generate a
- self-signed SSL certificate. For example, if you need to test with a self-signed
- certicate on Chrome or Chromimum browsers, one workaround is to start the browser
- with `--ignore-certificate-errors`.
+Optional: Using HAProxy as a proxy
+----------------------------------
+HAProxy can also be used to proxy HTTP, HTTPS, and WebSockets traffic
+as an alternative to NGINX.
+
+The following instructions are a guide for setting this up on Debian
+and Ubuntu systems, but expect general familiarity with various system
+administration and network tasks. The steps should be run as the *root*
+Linux account, and assume that you already followed the instructions
+for installing WebSockets support.
-8. After OpenSRF is up and running (or after any re-install),
- fire up the secondary Apache instance. Errors will appear in
- `/var/log/apache2-websockets/error.log`. Start apache2-websockets with:
+1. Install HAProxy if not already present:
+
-[source,bash]
+[source, bash]
+---------------------------------------------------------------------------
+apt-get install haproxy
+---------------------------------------------------------------------------
++
+2. Append the example HAProxy to `haproxy.cfg`.
++
+[source, bash]
+---------------------------------------------------------------------------
+cd /path/to/opensrf-OSRFVERSION
+cat examples/haproxy/osrf-ws-http-proxy >> /etc/haproxy/haproxy.cfg
+---------------------------------------------------------------------------
++
+3. Edit `/etc/haproxy/haproxy.cfg` to set the location
+ of the PEM file containing the SSL certificate and private key.
+4. Start HAProxy.
