./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：
