<title>Adding an Additional Proxy Server</title>
<para>For reliability&#8217;s sake you may want to
have more than one proxy server. You can set
up the additional proxy node in the same
manner that you set up the first proxy node
but with additional configuration
steps.</para>
<para>Once you have more than two proxies, you also
want to load balance between the two, which
means your storage endpoint (what clients use
to connect to your storage) also changes. You
can select from different strategies for load
balancing. For example, you could use round
robin dns, or a software or hardware load
balancer (like pound) in front of the two
proxies, and point your storage url to the
load balancer.</para>
<para>Configure an initial proxy node for the initial
setup, and then follow these additional steps
for more proxy servers.</para>
<orderedlist>
<listitem>
<para>Update the list of memcache
servers in
<filename>/etc/swift/proxy-server.conf</filename> for
all the added proxy servers. If you
run multiple memcache servers, use
this pattern for the multiple
IP:port listings:
<literallayout class="monospaced">10.1.2.3:11211,10.1.2.4:11211</literallayout>
in each proxy server&#8217;s conf
file.:</para>
<para>
<literallayout class="monospaced">
[filter:cache]
use = egg:swift#memcache
memcache_servers = &lt;PROXY_LOCAL_NET_IP&gt;:11211
</literallayout>
</para>
</listitem>
<listitem>
<para>Next, copy all the ring
information to all the nodes,
including your new proxy nodes, and
ensure the ring info gets to all
the storage nodes as well.</para>
</listitem>
<listitem>
<para>After you sync all the nodes,
make sure the admin has the keys in
<filename>/etc/swift</filename> and the ownership for
the ring file is correct.</para>
