Riak: 在OSX上快速搭建Riak开发集群

首先从Github上克隆riak-dev-cluster工具, 该工具创建的只是一个测试集群, 主要用于在开发中进行测试, 不建议在产品环境中使用.

1.根据Open File Limits设置进程对文件的打开数限制.

2.克隆参仓库

$ git clone git://github.com/basho/riak-dev-cluster.git
$ cd riak-dev-cluster

3.运行rake bootstrap配置,启动集群

rake bootstrap

4.显示集群成员节点的状态

➜  riak-dev-cluster git:(master) ✗ rake member_status
riak2/bin/riak-admin member-status
================================= Membership ==================================
Status     Ring    Pending    Node
-------------------------------------------------------------------------------
valid      25.0%      --      'riak1@127.0.0.1'
valid      18.8%      --      'riak2@127.0.0.1'
valid      18.8%      --      'riak3@127.0.0.1'
valid      18.8%      --      'riak4@127.0.0.1'
valid      18.8%      --      'riak5@127.0.0.1'
-------------------------------------------------------------------------------
Valid:5 / Leaving:0 / Exiting:0 / Joining:0 / Down:0

控制命令

该项目包含多个rake任务用于与Riak集群进行交互, 包括:

启动集群中的所有节点

rake start

首先运行rake stop停止所有节点并清除所有数据, 然后删除目录

rake clear

重启集群中的所有节点, 先运行rake stop 然后运行rake start

rake restart

把节点加入到集群(仅需要一次)

➜  riak-dev-cluster git:(master) ✗ rake join     
./riak2/bin/riak-admin join -f riak1@127.0.0.1
Failed: This node is already a member of a cluster
./riak3/bin/riak-admin join -f riak1@127.0.0.1
Failed: This node is already a member of a cluster
./riak4/bin/riak-admin join -f riak1@127.0.0.1
Failed: This node is already a member of a cluster
./riak5/bin/riak-admin join -f riak1@127.0.0.1
Failed: This node is already a member of a cluster

显示可用的命令

rake counter_bucket  # set up counters bucket-type
rake install         # install riak
rake join            # join riak nodes (only needed once)
rake map_bucket      # set up maps bucket-type
rake member_status   # riak-admin member-status
rake ping            # ping all riak nodes
rake restart         # restart all riak nodes
rake ring_status     # riak-admin ring-status
rake set_bucket      # set up sets bucket-type
rake start           # start all riak nodes
rake status          # riak-admin status
