指南

OS X 安装

$ brew update
$ brew install influxdb
$ influxd
$ influx
Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring.
Connected to http://localhost:8086 version 0.9.6.1
InfluxDB shell 0.9.6.1
> create database mydb
> show databases
> use mydb
> insert cpu,host=serverA,region=us_west value=0.64
> select * from cpu
> insert temperature,machine=unit42,type=assembly external=25,internal=37
> select * from temperature
> show series
> show measurements
> show tag keys
> show field keys

创建数据库

curl -G 'http://localhost:8086/query' --data-urlencode "q=CREATE DATABASE mydb"

插入数据

curl -XPOST 'http://localhost:8086/write?db=mydb' -d 'cpu,host=server01,region=uswest load=42 1434055562000000000'
curl -XPOST 'http://localhost:8086/write?db=mydb' -d 'cpu,host=server02,region=uswest load=78 1434055562000000000'
curl -XPOST 'http://localhost:8086/write?db=mydb'-d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'

查询数据

curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" --data-urlencode "q=SELECT * FROM cpu WHERE host='server01' AND time < now() - 1d"

分析数据

curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" --data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"

sample数据集

curl https://s3-us-west-1.amazonaws.com/noaa.water.database.0.9/NOAA_data.txt > sample-data.txt
influx -import -path=sample-data.txt -precision=s

提示信息: 2016/02/23 10:32:35 Processed 76290 inserts

> use NOAA_water_database
> show measurements
> select count(water_level) from h2o_feet
> select * from h2o_feet limit 5
