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

➜  riak-dev-cluster git:(master) ✗ rake rake -T rake bootstrap       # install, start, and join riak nodes rake clear           # clear data from all riak nodes 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 rake stop            # stop all riak nodes rake test            # riak-admin test
