安装HBase
wget https://mirror.bit.edu.cn/apache/hbase/stable/hbase-2.2.4-bin.tar.gz
tar xf hbase-2.2.4-bin.tar.gz
echo $JAVA_HOME
cd hbase-2.2.4
./bin/start-hbase.sh
jps (HMaster)
# 访问：http://localhost:16010/
./bin/stop-hbase.sh
访问HBase
./bin/hbase shell
hbase(main):001:0> help

安装Zookeeper
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz
tar xf apache-zookeeper-3.6.1-bin.tar.gz
cd apache-zookeeper-3.6.1-bin
vim conf/zoo.cfg
tickTime=2000
dataDir=/var/lib/zookeeper
clientPort=2181
bin/zkServer.sh start
telnet localhost 2181
安装OpenTSDB
wget https://github.com/OpenTSDB/opentsdb/releases/download/v2.4.0/opentsdb-2.4.0.noarch.rpm
yum install opentsdb-2.4.0.noarch.rpm -y
# HBase建表
env COMPRESSION=NONE HBASE_HOME=./hbase-2.2.4 /usr/share/opentsdb/tools/create_table.sh
# 配置文件

# tsd.http.cachedir - Path to write temporary files to

向TSD写数据
name schema 命名格式
-
metric name
指标名 如 sys.cpu.user
-
tag
标签 如 host=webserver01,cpu=0 用于定位具体的time series
every time series in opentsdb must have at least one tag
time series由 metric name 和 tag 组合定义，查询格式如下：
# ${aggregation}:${metric name}{$tag1, $tag2}
sum:sys.cpu.user{host=webserver01,cpu=42}
sum:sys.cpu.user
start=1d-ago&m=avg:sys.cpu.user{host=webserver01}
Limited Unique IDs(UIDs) UID限制
opentsdb会为每一个metric name,tag name(tagk),tag value(tagv)分配一个ID好，默认有1600万个可分配的ID，如果用完了数据就无法写入了。
当创建一个新的TSDB时我们可以设置UID的宽度：
tsd.storage.uid.width.metric
tsd.storage.uid.width.tagk
tsd.storage.uid.width.tagv
Data Specification 数据字段
metric, timestamp, value, tags
添加自动创建metric,tag配置
tsd.core.auto_create_metrics = true
# 下面两个默认为true
tsd.core.auto_create_tagks = true
tsd.core.auto_create_tagvs = true

put sys.cpu.user 1356998400 42.5 host=webserver01 cpu=0
