+Installing OpenSRF
+==================
Preamble: referenced user accounts
----------------------------------
** The *user* Linux account is the account that you use to log onto the
Linux system as a regular user.
** The *root* Linux account is an account that has system administrator
- privileges. On Debian and Fedora you can switch to this account from
+ privileges. On Debian you can switch to this account from
your *user* account by issuing the `su -` command and entering the
password for the *root* account when prompted. On Ubuntu you can switch
to this account from your *user* account using the `sudo su -` command
of installing OpenSRF. You can switch to this account from the *root*
account by issuing the `su - opensrf` command.
+Download and unpack the code

Configuration and compilation instructions
If you are building OpenSRF for Evergreen, issue the following commands as
the *user* Linux account to configure and build OpenSRF:
+[source, bash]
---------------------------------------------------------------------------
./configure --prefix=/openils --sysconfdir=/openils/conf
make
You can add the `--enable-python` option to the configure command
to build Python support and `--enable-java` for Java support.
+If you are planning on proxying WebSockets traffic (see below), you
+can add `--with-websockets-port=443` to specify that WebSockets traffic
+will be going through port 443. Without that option, the default port
+is 7682.

You should receive the value `4`.
+Optional: Websockets installation instructions
+----------------------------------------------
+Websockets are new to OpenSRF 2.4+ and are required for operating the new web-based
+staff client for Evergreen. Complete the following steps as the *root* Linux
+account:
+
+1. Install git if not already present:
++
+[source, bash]
+---------------------------------------------------------------------------
+apt-get install git-core
+---------------------------------------------------------------------------
++
+2. Install the apache-websocket module:
++
+[source, bash]
+---------------------------------------------------------------------------
+# Use a temporary directory
+cd /tmp
+git clone https://github.com/disconnect/apache-websocket
+cd apache-websocket
+apxs2 -i -a -c mod_websocket.c
+---------------------------------------------------------------------------
++
+3. Create the websocket Apache instance (more information about this in
+ `/usr/share/doc/apache2/README.multiple-instances`)
++
+.(Debian)
+[source, bash]
+---------------------------------------------------------------------------
+sh /usr/share/doc/apache2.2-common/examples/setup-instance websockets
+---------------------------------------------------------------------------
++
+.(Ubuntu Trusty / Xenial)
+[source, bash]
+---------------------------------------------------------------------------
+sh /usr/share/doc/apache2/examples/setup-instance websockets
+---------------------------------------------------------------------------
++
+4. Remove from the main apache instance
++
+[source, bash]
+---------------------------------------------------------------------------
+a2dismod websocket
+---------------------------------------------------------------------------
++
+5. Change to the directory into which you unpacked OpenSRF, then copy into
+ place the config files
++
+.(Debian)
+[source, bash]
+---------------------------------------------------------------------------
+cd /path/to/opensrf-OSRFVERSION
+cp examples/apache2/websockets/apache2.conf /etc/apache2-websockets/
+---------------------------------------------------------------------------
++
+.(Ubuntu Trusty / Xenial)
+[source, bash]
+---------------------------------------------------------------------------
+cd /path/to/opensrf-OSRFVERSION
+cp examples/apache_24/websockets/apache2.conf /etc/apache2-websockets/
+---------------------------------------------------------------------------
++
+6. OPTIONAL: add these configuration variables to `/etc/apache2-websockets/envvars`
+ and adjust as needed.
++
+[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
+---------------------------------------------------------------------------
++
+ * `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.
+
+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`.
+
+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:
++
+[source, bash]
+---------------------------------------------------------------------------
+/etc/init.d/apache2-websockets start
+---------------------------------------------------------------------------
+
+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:
++
+[source, bash]
+---------------------------------------------------------------------------
+apt-get install nginx
+---------------------------------------------------------------------------
++
+2. Configure the main Apache instance 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.
+3. Copy the example NGINX configuration file into place.
++
+[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
+---------------------------------------------------------------------------
++
+4. Edit `/etc/nginx/sites-available/osrf-ws-http-proxy` to set the location
+ of the SSL certificate and private key.
+5. Start NGINX
++
+[source, bash]
+---------------------------------------------------------------------------
+/etc/init.d/nginx start
+---------------------------------------------------------------------------
++
+6. 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]
+---------------------------------------------------------------------------
+var WEBSOCKET_PORT_SSL = 7682;
+---------------------------------------------------------------------------
++
+to
++
+[source, javascript]
+---------------------------------------------------------------------------
+var WEBSOCKET_PORT_SSL = 443;
+---------------------------------------------------------------------------
+
+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.
+
+1. Install HAProxy if not already present:
++
+[source, bash]
+---------------------------------------------------------------------------
+apt-get install haproxy
+---------------------------------------------------------------------------
++
+2. Configure the main Apache instance 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.
+3. 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
+---------------------------------------------------------------------------
++
+4. Edit `/etc/haproxy/haproxy.cfg` to set the location
+ of the PEM file containing the SSL certificate and private key.
+5. Start HAProxy.
++
+[source, bash]
+---------------------------------------------------------------------------
+/etc/init.d/haproxy start
+---------------------------------------------------------------------------
++
+6. Edit `<PREFIX>/javascript/opensrf_ws.js` and `<PREFIX>/javascript/opensrf_ws_shared.js`
+ and change
++
+[source, javascript]
+---------------------------------------------------------------------------
+var WEBSOCKET_PORT_SSL = 7682;
+---------------------------------------------------------------------------
++
+to
++
+[source, javascript]
+---------------------------------------------------------------------------
+var WEBSOCKET_PORT_SSL = 443;
