Post-install steps section is an old label from the rpevious install guide layout. This change bring swifts in-line with other parts of the guide, which use the new layout. Existing content labels do not change, meaning they are still searchable and linkable as before, but an htaccess modification was added for the index page.

<title>Add another proxy server</title>
|
|
<para>To provide additional reliability, and bandwidth
|
|
to your cluster, you add proxy servers. You can
|
|
set up an additional proxy node the same way
|
|
that you set up the first proxy node but with
|
|
additional configuration steps.</para>
|
|
<para>After you have more than two proxies, you must
|
|
load balance them; 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. Then, complete
|
|
these steps to add proxy servers.</para>
|
|
<procedure>
|
|
<step>
|
|
<para>Update the list of memcache
|
|
servers in the
|
|
<filename>/etc/swift/proxy-server.conf</filename>
|
|
file for added proxy servers. If
|
|
you run multiple memcache servers,
|
|
use this pattern for the multiple
|
|
IP:port listings in each proxy
|
|
server configuration file:</para>

<step>
|
|
<para>Copy ring information to all
|
|
nodes, including new proxy nodes.
|
|
Also, ensure that the ring
|
|
information gets to all storage
|
|
nodes.</para>

</step>

<step>
|
|
<para>After you sync all nodes, make
|
|
sure that the admin has keys in
|
|
<filename>/etc/swift</filename> and
|
|
the ownership for the ring file is
|
|
correct.</para>
