什么是InfluxDB

InfluxDB 是一个用于存储和分析时间序列数据的开源数据库。由 Golang 语言编写，也是由 Golang 编写的软件中比较著名的一个，在很多 Golang 的沙龙或者文章中可能都会把 InfluxDB 当标杆来介绍，这也间接帮助 InfluxDB 提高了知名度。

特点

高压缩比：由于数据每分每秒都在变化，海量的时序数据往往体量巨大，占用大量硬件资源，所以需要优化数据压缩算法提高数据压缩比。
高并发写入：时序数据库采用持续高并发写入数据，无更新的方式，对于时间相同的重复的数据，只保留一份数据。
低延时、高并发查询：通过索引降低查询延时，通过缓存等技术提高数据并发能力。

使用场景

IOT行业：电力、化工等工业物联网数据监测
金融行业：各类金融产品及其衍生品、数字货币数据存储与量化研究
IT行业：服务器、虚拟机、容器等的状态数据实时监测
互联网行业：用户行为轨迹，日志等数据。

目前比较流行的时序数据库有：InfluxDB、Prometheus、OpenTSDB、TDengine等，其中使用最广泛的当属InfluxDB，行业内应用最广泛。还有就是刚进入业内视野的国产时序数据库TDengine。而Prometheus则是Prometheus监控系统自带的数据库。

官网下载地址
按照图片选择

接着我们连接上服务器。

#创建文件夹
mkdir /opt/software
# 进入创建的文件夹
cd /opt/software
# 下载
wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.7.6_linux_amd64.tar.gz

#解压
tar -zxvf influxdb2-2.7.6_linux_amd64.tar.gz

#进入到启动脚本位置
cd influxdb2-2.7.6/usr/bin

#启动
./influxd

启动后控制台会输出
