As long as your Riak KV client can reach one Riak server, it should be able to write data. ## riak TS Riak TS is a distributed NoSQL key/value store optimized for time series data. With TS, you can associate a number of data points with a specific point in time. TS uses discrete slices of time to co-locate data. For example, humidity and temperature readings from a meter reported during the same slice of time will be stored together on disk. Riak TS uses tables defined according to a schema for each coherent group of data. This allows for both flexibility, in terms of collecting many different sets of data, and enough structure to make the experience of working with the collected data better. ## riak CS Riak CS (Cloud Storage) is easy-to-use object storage software built on top of Riak KV, Basho’s distributed database. Riak CS is designed to provide simple, available, distributed cloud storage at any scale, and can be used to build cloud architectures—be they public or private—or as storage infrastructure for heavy-duty applications and services. Riak CS’s API is Amazon S3 compatible and supports per-tenant reporting for use cases involving billing and metering. ## riak安装 真心没有见过比riak还难安装的软件了，找了N中办法，都没有安装成功，总是报错。终于今天使用rpm安装成功。 ``` curl -s https://packagecloud.io/install/repositories/basho/riak/script.rpm.sh | sudo bash sudo yum install riak-2.2.3-1.el7.centos.x86_64 ``` **安装完成后 需要修改配置文件:/etc/riak/riak.conf** ``` listener.http.internal = 192.168.11.25:8098 listener.protobuf.internal = 192.168.11.25:8087 ``` **以上为centos7安装步骤，如果其他系统，请点击下面的链接** [https://packagecloud.io/basho/riak/packages/el/7/riak-2.2.3-1.el7.centos.x86_64.rpm](https://packagecloud.io/basho/riak/packages/el/7/riak-2.2.3-1.el7.centos.x86_64.rpm) ## 测试 ## 相关阅读 [riak源码](https://github.com/basho/riak) [riak-java-client源码](https://github.com/basho/riak-java-client) [riak docs文档](https://www.tiot.jp/riak-docs/) ## 联系方式 **以上观点纯属个人看法，如有不同，欢迎指正。 email:<babymm@aliyun.com> github:[https://github.com/babymm](https://github.com/babymm)**
