本文是我自己在Macbook上本地从零开始搭建一套MySQL监控平台，监控的也是我本机的MySQL，过程包括prometheus、mysql_exporter、Grafana的配置与下载。

一、软件安装

我是根据Mac挑选的如下版本下载：

OS	Arch
darwin	amd64

prometheus：Download | Prometheus->prometheus->prometheus-2.43.0.darwin-amd64.tar.gz

mysql_exporter：Download | Prometheus->mysqld_exporter->mysqld_exporter-0.15.0-rc.0.darwin-amd64.tar.gz

Grafana：Download Grafana | Grafana Labs-> Mac

二、软件配置

配置mysql_exporter

进入上面mysqld_exporter-0.15.0-rc.0.darwin-amd64解压的目录中，touch my.cnf创建配置文件

进行my.cnf文件配置

输入想要采集数据的登陆用户信息，即本地数据库信息

[client] 
# mysql用户名 
user=xxxxx  
 
#mysql的密码
password=xxxxx
 
#主机地址
host=localhost
 
# mysql端口号
prot=3306

启动mysql-exporter

./mysqld_exporter --config.my-cnf=./my.cnf

本地浏览器访问端口9104监控页面
```
http://localhost:9104/
```
显示如下，则成功，但是这亮橙色，真的很容易让人认为报错了orz：

在这里插入图片描述

点进去Metrics就能看到具体的采集到的信息

配置prometheus

进入上面mysqld_exporter-0.15.0-rc.0.darwin-amd64解压的目录中

配置prometheus.yml文件中的scrape_configs

以相同的格式，添加mysql的监听任务以及其监听端口9104：

- job_name: "mysql"

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

    static_configs:
      - targets: ["localhost:9104"]

最终如下：

# 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=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

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

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

  - job_name: "mysql"

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

    static_configs:
      - targets: ["localhost:9104"]
