prepare
1.synchronized using NTP(network time protocol)
2.static your IP
3.ssh login without password
4.JDK7 is neccessary
start
1.在每一个节点上安装cassandra
2.为集群选取一个名称(这个很重要)
3.获取每一个节点的IP
4.选择一个snitch
下面以一个六个节点分为两个机架的集群为例,每个节点配置如下:
cluster_name: 'MyDemoCluster'
auto_bootstrap: false(仅仅当本机作为新的节点时)
num_tokens: 256seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider
parameters:
- seeds: "110.82.155.0,110.82.155.3"
listen_address: 110.82.155.0(每个节点此IP需要改成本机)
rpc_address: 0.0.0.0
endpoint_snitch: RackInferringSnitch
节点信息如下
node0 110.82.155.0 (seed1)
node1 110.82.155.1
node2 110.82.155.2
node3 110.82.156.3 (seed2)
node4 110.82.156.4
node5 110.82.156.5
如果你不熟悉防火墙配置,关闭即可
启动后使用nodetool status检查
