1: Introduction

InfluxDB is an open source distributed timing, event, and metrics database. Written in the Go language without external dependencies. Its design goal is to achieve distributed and horizontal scaling expansion.

1, it has three major features:

1. Time series (timeseries): You can use time-related functions (such as Max, Min, sum, etc.)

2. Metrics (Metric): You can calculate large amounts of data in real time

3. Eevents (Event): It supports arbitrary event data

2. Features

Schemaless (unstructured), can be any number of columns

Scalable

Min, max, sum, count, mean, median a series of functions for convenient statistics

Native http API, built-in HTTP support, read and write using HTTP

3. API

InfluxDB supports two API modes

HTTP API

Protobuf API

2: Installation Deployment

5: The service uses the port by default:

Networking By default, InfluxDB uses the following network ports:

TCP Port 8083 is used for InfluxDB ' s Admin panel

TCP Port 8086 is used for client-server communication over InfluxDB ' s HTTP API

TCP Ports 8088 and 8091 is required for clustered InfluxDB instances
