For reliability’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. 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. Configure an initial proxy node for the initial setup, and then follow these additional steps for more proxy servers. Update the list of memcache servers in /etc/swift/proxy-server.conf for all the added proxy servers. If you run multiple memcache servers, use this pattern for the multiple IP:port listings: 10.1.2.3:11211,10.1.2.4:11211 in each proxy server’s conf file: [filter:cache] use = egg:swift#memcache memcache_servers = <PROXY_LOCAL_NET_IP>:11211 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. After you sync all the nodes, make sure the admin has the keys in /etc/swift and the ownership for the ring file is correct.
