我最近在研究Hypertable， Hypertable 安装分为单机安装与分布式文件系统，单击安装主要用于开发环境。生产环境一般都是采用分布式文件系统。Hypertable 系统以下几种组合。
Hypertable + HDFS（Hadoop）
Hypertable + KFS
Hypertable + MapR
Hypertable + ThriftBroker
前面三种，我既然选择了 Hypertable 而不用 HBase 就是不喜欢Java 所以我不会使用 Hadoop.
第二种 Hypertable + KFS 我去看了KFS Subversion 最有一次更新时2011年， 放弃了KFS
第三重 MapR 没有听说过，资料也比较少
看到最后一种 ThriftBroker 可以持之 Ceph 就像尝试。
Hypertable 安装参考：
http://netkiller.github.io/nosql/hypertable/index.html
Ceph
修改 CephBroker.MonAddr 对应的服务器与端口号即可
# cat hypertable.cfg # # hypertable.cfg # # HDFS Broker HdfsBroker.Hadoop.ConfDir=/etc/hadoop/conf # Ceph Broker CephBroker.MonAddr=192.168.6.2:6789 # Local Broker DfsBroker.Local.Root=fs/local # DFS Broker - for clients DfsBroker.Port=38030 # Hyperspace Hyperspace.Replica.Host=localhost Hyperspace.Replica.Port=38040 Hyperspace.Replica.Dir=hyperspace # Hypertable.Master Hypertable.Master.Port=38050 # Hypertable.RangeServer Hypertable.RangeServer.Port=38060 Hyperspace.KeepAlive.Interval=30000 Hyperspace.Lease.Interval=1000000 Hyperspace.GracePeriod=200000 # ThriftBroker ThriftBroker.Port=38080
启动 dfsbroker
# /opt/hypertable/current/bin/start-dfsbroker.sh ceph
下面是Ceph 的安装
Ceph

创建目录
sudo mkdir -p /var/lib/ceph/osd/ceph-0 sudo mkdir -p /var/lib/ceph/osd/ceph-1 sudo mkdir -p /var/lib/ceph/mon/ceph-a sudo mkdir -p /var/lib/ceph/mds/ceph-a
创建key文件
$ cd /etc/ceph $ sudo mkcephfs -a -c /etc/ceph/ceph.conf -k ceph.keyring
创建key文件过程如下
