Installation instructions:
-=========================
+--------------------------
Once you have configured and compiled OpenSRF, issue the following
command as the root user to install OpenSRF:
+---------------------------------------------------------------------------
make install
+---------------------------------------------------------------------------
This will install OpenSRF in the prefix directory that you specified in the
configuration step. This will also install example configuration files that
you can use as templates for your own configuration files.
Create and set up the opensrf Unix user environment:
-===================================================
+----------------------------------------------------
This user is used to start and stop all OpenSRF processes, and must own all
files contained in the PREFIX directory hierarchy. Issue the following
-commands as root to create the "opensrf" user and set up its environment,

-# echo "export PERL5LIB=/openils/lib/perl5:\$PERL5LIB" >> /home/opensrf/.bashrc
# passwd opensrf
+---------------------------------------------------------------------------
Define your public and private OpenSRF domains:
-==============================================
+-----------------------------------------------
For security purposes, OpenSRF uses Jabber domains to separate services
into public and private realms. Throughout these instructions, we will use
-the example domains "public.localhost" and "private.localhost".
+the example domains `public.localhost` and `private.localhost`.
On a single-server system, the easiest way to define public and private
-domains is to define separate hostnames by adding entries to the
-/etc/hosts file. Here are entries that you could make to a stock /etc/hosts
-file for our example domains:

Configure the ejabberd server:
-=============================
+------------------------------
OpenSRF requires an XMPP (Jabber) server. For performance reasons, ejabberd is
the Jabber server of choice for the OpenSRF project. In most cases, you only
-have to make a few changes to the default ejabberd.cfg file to make ejabberd

Create the OpenSRF Jabber users:
-===============================
+--------------------------------
On each domain, you need two Jabber users to manage the OpenSRF communications:
- * a "router" user, to whom all requests to connect to an OpenSRF service
- will be routed; this Jabber user must be named "router"
- * an "opensrf" user, which clients use to connect to OpenSRF services; this
+ * a `router` user, to whom all requests to connect to an OpenSRF service
+ will be routed; this Jabber user must be named `router`
+ * an `opensrf` user, which clients use to connect to OpenSRF services; this
user can be named anything you like
Create the Jabber users by issuing the following commands as root. Substitute
<password> for your chosen passwords for each user respectively:
+---------------------------------------------------------------------------
# ejabberdctl register router private.localhost <password>
# ejabberdctl register opensrf private.localhost <password>
# ejabberdctl register router public.localhost <password>
# ejabberdctl register opensrf public.localhost <password>
+---------------------------------------------------------------------------
Update the OpenSRF configuration files:
-======================================
+---------------------------------------
There are two critical files that you must update to make OpenSRF work.
-"SYSCONFDIR" is "/opensrf/etc" by default, or the value that you passed to
---sysconfdir during the configuration phase:

- * You must alter the <dbfile> element value for the "opensrf.persist"
- service to point to a directory to which the opensrf user can write.

- the general service definition value.
- * SYSCONFDIR/opensrf_core.xml - this file lists the Jabber connection
+ * `SYSCONFDIR/opensrf_core.xml` - this file lists the Jabber connection
information that will be used for the system, as well as determining
logging verbosity and defining which services will be exposed on the
HTTP gateway. There are four username/password pairs to update in this
file:
- 1. <config><opensrf> = use the private Jabber "opensrf" user
- 2. <config><gateway> = use the public Jabber "opensrf" user
- 3. <config><routers><router> = use the public Jabber "router" user

Troubleshooting note for Python users:

If you are running a Python client and trying to connect to OpenSRF running on
localhost rather than a hostname that can be resolved via DNS, you will
-probably receive exceptions about "dns.resolver.NXDOMAIN". If this happens,
-you need to install the dnsmasq package, configure it to serve up a DNS
-entry for localhost, and point your local DNS resolver to dnsmasq. For example,
+probably receive exceptions about `dns.resolver.NXDOMAIN`. If this happens,
