在于Unix的平台上，文件使用0600权限编写，因此您应确保只有受信任的进程才能与Consul作为同一户执行。在Windows上，您应确保该目录具有适当的权限，因为这些权限将被继承。 ● datacenter：此标志控制代理程序运行的数据中心。如果未提供，则默认为“dc1”。Consul拥有多个数据中心的一流支持，但它依赖于正确的配置。同一数据中心中的节点应位于单个LAN上。 ● dev：启用

the primary considerations are (1) being able to satisfy reads locally, without incurring cross-datacenter latency, and (2) failure scenarios. The two most common ways to configure multiple data center number of replicas per data center in a comma-separated list of datacenter_name:number_of_replicas. Note that what you specify for datacenter_name depends on the cluster-configured snitch you are using. There NetworkTopologyStrategy: [default@unknown] UPDATE KEYSPACE demo WITH strategy_options = [ {datacenter1:6, datacenter2:6}]; 2. On each node in the cluster, run nodetool repair for each keyspace that was updated

specified multiple times. 23. Datacenter of the agent (deprecated: use ‘datacenter’ instead). 24. -dc=east-aws ‘datacenter’ instead. Datacenter of the agent. 25. -datacenter=east-aws Provides the gossip 的绑定地址，包括：HTTP、DNS、RPC 。默认是127.0.0.1，只允许回环接口访问 。若不指定为-server，其实就是-client -join 。作用：将节点加入到集群 -datacenter（老版本叫-dc，-dc已经失效） 。作用：指定机器加入到哪一个数据中心中 如上，大家应该可以猜到， 使用 -client 参数可指定允许客户端使用什么ip去访问，例如 client 192 11.143 -datacenter=dc1 -ui -client=192.168.11.143 -server -bootstrap- expect 1 启动node1机器上的Consul（node1机器上执行）： consul agent -data-dir /tmp/node1 -node=node1 -bind=192.168.11.144 -datacenter=dc1 -ui
