<title>Add a proxy server</title>
|
|
<para>For reliability, 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>
|
|
<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>
