简介： 在Windows下使用JMeter集群+Influxdb存储+Grafana实时数据展示

一、下载安装Influxdb

Influxdb是一个开源分布式时序、时间和指标数据库，使用 Go 语言编写，无需外部依赖。其设计目标是实现分布式和水平伸缩扩展，是 InfluxData 的核心产品。
应用：性能监控，应用程序指标，物联网传感器数据和实时分析等的后端存储。
Influxdb 完整的上下游产业还包括：Chronograf、Telegraf、Kapacitor，其具体作用及关系如下：

1，到https://dl.influxdata.com/influxdb/releases/influxdb2-2.0.6-windows-amd64.zip下载influxdb2-2.0.6-windows-amd64.zip。

2，将下载下来的zip文件存储在本地一个非中文目录下（我下载在influxdb-1.7.3-1下）。

3，进入安装目录，用文本编辑器打开influxdb.conf。

4，按如下红字部分进行编辑

…
[meta]
  # Where the metadata/raft database is stored
  # dir = "/var/lib/influxdb/meta"
  dir = "C:\\influxdb\\meta"
  #我设为C:\\influxdb，数据库文件将产生在C:\\influxdb目录下。
  # Automatically create a default retention  policy when creating a database.
  retention-autocreate  = true
  # If log messages are printed for the meta  service
  logging-enabled  = true
…
[data]
  # The directory where the TSM storage  engine stores TSM files.
  dir  = "C:\\influxdb\\meta"
  # The directory where the TSM storage  engine stores WAL files.
  wal-dir  = "C:\\influxdb\\wal"
…
[retention]
  # Determines whether retention policy  enforcement enabled.
  enabled  = true
  # The interval of time when retention  policy enforcement checks run.
  check-interval  = "30m"
…
[shard-precreation]
  # Determines whether shard pre-creation  service is enabled.
  enabled  = true
  # The interval of time when the check to  pre-create new shards runs.
  check-interval  = "10m"
  # The default period ahead of the endtime  of a shard group that its successor
  # group is created.
  advance-period  = "30m"
…
[monitor]
  # Whether to record statistics internally.
  store-enabled  = true
  # The destination database for recorded  statistics
  store-database  = "_internal"
  # The interval at which to record  statistics
  store-interval  = "10s"
…

5，用influxd -config influxdb.conf运行

influxd -config influxdb.conf
C:\influxdb-1.7.3-1>influxd  -config influxdb.conf
 8888888           .d888 888                   8888888b.  888888b.
   888            d88P"  888                   888  "Y88b 888  "88b
   888            888    888                    888    888 888   .88P
   888    88888b.  888888 888 888  888 888   888 888    888 8888888K.
   888    888 "88b 888    888  888  888  Y8bd8P' 888    888 888   "Y88b
   888    888  888 888    888 888   888   X88K   888     888 888    888
   888    888  888 888    888 Y88b 888 .d8""8b. 888  .d88P 888    d88P
 8888888 888   888 888    888  "Y88888 888  888 8888888P"  8888888P"
…
2021-06-04T09:46:34.406806Z     info     Starting retention policy enforcement service   {"log_id":  "0UXbWmRG000", "service": "retention",  "check_interval": "30m"}
2021-06-04T09:46:34.408611Z     info     Listening for signals    {"log_id": "0UXbWmRG000"}
2021-06-04T09:46:34.408611Z     info     Sending usage statistics to usage.influxdata.com        {"log_id":  "0UXbWmRG000"}

如果出现Sending usage statistics to usage.influxdata.com，表示Influxdb启动成功。

二、配置Influxdb

用InfluxDB Studio配置

InfluxDB Studio是InfluxDB的图形化配置界面。

1，通过以下连接获得InfluxDB Studio

链接：https://pan.baidu.com/s/1CRJXtmj_W5bIEJjkP0mR5g

提取码：ok87

2，解压后直接运行InfluxDBStudio.exe

3，点击如下图标：

4，输入任意的连接名，地址（默认为localhost），端口（默认为8086），用户名和密码。点击【Test】，显示测试成功，点击【Save】，保存关闭。

5，左边树状结构如下。_internal为默认数据库

6，按下面顺序依次建立jmeter数据库

用命令行配置

1，在命令行，运行Influxdb，进入Influxdb命令行

Connected to  http://localhost:8086 version 1.7.3
InfluxDB shell  version: 1.7.3
Enter an InfluxQL  query
>

2，依次键入如下命令

>CREATE USER  admin WITH PASSWORD 'admin' WITH ALL PRIVILEGES
>auth admin admin
>CREATE DATABASE  jmeter
>show databases  use jmeter
>show measurements
