1、 安装 Prometheus

Prometheus 基于 Golang 编写，编译后的软件包，不依赖于任何的第三方依赖。只需要 下载对应平台的二进制包，解压并且添加基本的配置即可正常启动 Prometheus Server。

1、解压

tar -zxvf prometheus-2.26.0.linux-amd64.tar.gz -C /opt/module
mv /opt/module/prometheus-2.26.0.linux-amd64 /opt/module/prometheus

2、 修改配置文件 prometheus.yml

vim /opt/module/prometheus/prometheus.yml

在 scrape_configs 配置项下添加配置： 

scrape_configs:

 - job_name: 'prometheus'
 static_configs:
 - targets: ['bigdata:9090']
#添加 ClickHouse 监控配置
  - job_name: clickhouse-1
    static_configs:
    - targets: ['bigdata:9363']

记住：一定空格要对齐

3、 启动 Prometheus Server

nohup /opt/module/prometheus/prometheus --config.file=/opt/module/prometheus/prometheus.yml > /opt/module/prometheus/logs/prometheus.log 2>&1 &

4、浏览器登陆

http://bigdata:9090/

prometheus 是 up 状态，表示安装启动成功： 

5、关闭

 netstat -apn | grep 9090

6、脚本封装

vim /home/bigdata/bin/prometheus.sh

#!/bin/bash
/opt/module/prometheus/prometheus --config.file=/opt/module/prometheus/prometheus.yml >> /opt/module/prometheus/logs/prometheus.log

vim /usr/lib/systemd/system/prometheus.service

[Unit]
Description=https://prometheus.io

[Service]
ExecStart=/home/bigdata/bin/prometheus.sh
Restart=on-failure

[Install]
WantedBy=multi-user.target

注意

systemctl daemon-reload      # 重启systemctl
systemctl start prometheus     # 启动普罗米修斯
systemctl stop prometheus      # 关闭普罗米修斯 
systemctl restart prometheus  #重新启动普罗米修斯
systemctl status prometheus   #查看状态

2、  Grafana 安装

1、 上传并解压

三只松鼠小美好零食大礼包约3斤13袋/14袋（新老包装混发）

京东购物

59.90 Purchase

 tar -zxvf grafana-7.5.2.linux-amd64.tar.gz -C /opt/module/
 mv /opt/module/grafana-7.5.2/ /opt/module/grafana

2、 启动 Grafana

nohup /opt/module/grafana/bin/grafana-server > /opt/module/grafana/logs/grafana.log 2>&1 &

3、配置mysql作为数据源

vim /opt/module/grafana/conf/custom.ini

[paths]
data = /opt/module/grafana/data
temp_data_lifetime = 24h
logs = /opt/module/grafana/logs
plugins = /opt/module/grafana/plugins
provisioning = /opt/module/grafana/conf/provisioning

[database]
type = mysql
host = bigdata:3306
name = grafana
user = root
password = [email protected]
url = mysql://root:[email protected]@bigdata:3306/grafana
[root@bigdata conf]# pwd
/opt/module/grafana/conf

4、登陆页面

打开 web：http://bigdata:3000,默认用户名和密码：admin

5、脚本封装

vim /home/bigdata/bin/grafana.sh

#!/bin/bash
/opt/module/grafana/bin/grafana-server --config=/opt/module/grafana/conf/defaults.ini  --homepath=/opt/module/grafana >> /opt/module/grafana/logs/grafana.log

vim /usr/lib/systemd/system/grafana-server.service

[Service]
ExecStart=/home/bigdata/bin/grafana.sh

[Install]
WantedBy=multi-user.target

[Unit]
Description=Grafana
After=network.target

注意

systemctl daemon-reload      # 重启systemctl
systemctl start grafana-server     # 启动grafana
systemctl stop grafana-server      # 关闭grafana
systemctl restart grafana-server  #重新启动grafana
systemctl status grafana-server   #查看状态
