Cluster rippled Servers
集群rippled服务器
If you are running multiple rippled servers in a single datacenter, you can configure those servers into a cluster to maximize efficiency. Running your rippled servers in a cluster provides the following benefits:
如果用户在单个数据中心中运行多个ripple服务器实例的话，Ripple建议这些服务器集群化以提升效率。在集群模式下运行rippled服务器将带来以下优势：
Clustered rippled servers share the work of cryptography. If one server has verified the authenticity of a message, the other servers in the cluster trust it and do not re-verify.
集群化的rippled服务器共享密码学工作。如果一台服务器已验证一条消息的真实性，则集群中的其他服务器将直接信息该消息而不再重复验证。
Clustered servers share information about peers and API clients that are misbehaving or abusing the network. This makes it harder to attack all servers of the cluster at once.
集群化的服务器共享有关对等节点和API客户端不当或滥用网络的信息。使其很难一次性攻击集群中的所有服务器。
Clustered servers always propagate transactions throughout the cluster, even if the transaction does not meet the current load-based transaction fee on some of them.
集群化的服务器始终在集群中传递交易，即使该交易不满足某些服务器上基于负载的交易费用要求。
To enable clustering, change the following sections of your config file for each server:
要启用集群，在要加入集群的每个服务器中修改配置文件的以下部分：
List the IP address and port of each other server under the [ips_fixed] section. The port should be the one from the other servers’ protocol = peer setting in their rippled.cfg. Example:
在[ips_fixed]中列出所有其他对端服务器IP和端口号。端口号必须是对端服务器中配置文件所指定的端口号。
[ips_fixed]
192.168.0.1 51235
192.168.0.2 51235
Generate a unique seed (using the validation_create method) for each of your servers, and configure it under the [node_seed] section. The rippled server uses this key to sign its messages to other servers in the peer-to-peer network.
为每个服务器生成唯一种子（使用validation_create方法），并在[node_seed]下配置。rippled服务器使用这个密钥在P2P网络中签名其消息。
Add the public keys (for peer communication) of each of your other servers under the [cluster_nodes] section.
在[cluster_nodes]中添加其他每个服务器的公钥（用于对等网络通信）。
