Prometheus（一）之基础安装

一、准备条件

Windows10

go1.15.1.windows-amd64

二、下载与安装

1、下载

Download | Prometheus，依据需求选择对应版本的包，此处选择 Windows 对应版本 amd64

2、解压文件

解压到目标安装目录，此处为D:\ProgramData\prometheus-2.23.0-rc，解压之后，目录结构如下：

              consoles
              console_libraries
            11,357 LICENSE
             3,420 NOTICE
        89,340,928 prometheus.exe
               926 prometheus.yml
        79,250,432 promtool.exe

3、修改配置

解压路径中的配置文件为prometheus.yml，系统默认的数据存储方式为文件形式，存储在与执行程序prometheus.exe同目录下的data文件夹中，可以通过指令--storage.tsdb.path="data/"进行数据存储路径的设置。

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']

4、运行访问

在 cmd 中启动 prometheus.exe ，可看到如下输出：

level=info ts=2020-11-26T10:36:59.027Z caller=head.go:722 component=tsdb msg="WAL replay completed" checkpoint_replay_duration=0s wal_replay_duration=996.2µs total_replay_duration=1.9937ms

level=info ts=2020-11-26T10:36:59.040Z caller=main.go:694 msg="Server is ready to receive web requests."

执行成功后访问http://localhost:9090/能够出现对应页面，则表示访问成功。
