./influxd [--config yourconfigfile 2> /dev/null]  之所以重定向 因为默认log是stderr

再启动客户端./influx

可以看到是schema free的，可以动态的添加字段！！！

插入数据：

Time Series Name：对应数据库的表名，比如已经创建的cpu表。
Values：一条记录的取值，InfluxDB不需要先定义列，根据mongodb类似！

python代码：

>>> from influxdb import InfluxDBClient

json_body = [
{
"measurement": "cpu_load_short",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2009-11-10T23:00:00Z",
"fields": {
"value": 0.64
}
}
]

client = InfluxDBClient('localhost', 8086, 'root', 'root', 'example')

client.create_database('example')

client.write_points(json_body)

result = client.query('select value from cpu_load_short;')

print("Result: {0}".format(result))

查看数据：

~/influxdb-1.2.2-1/usr/bin/influx

Connected to http://localhost:8086 version 1.2.2

InfluxDB shell version: 1.2.2

use example
Using database example
select * from cpu_load_short
name: cpu_load_short
time host region value
