介绍prometheus的安装部署。

01:Prometheus部署

1.1:直接运行二进制文件

安装包获取:https://prometheus.io/download/

wget https://github.com/prometheus/prometheus/releases/download/v2.34.0/prometheus-2.34.0.linux-amd64.tar.gz

tar -xf prometheus-2.34.0.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/
ln -s prometheus-2.34.0.linux-amd64/ prometheus
cd prometheus
./prometheus # 前台启动,并以当前目录的prometheus.yml作为配置文件运行

自定义prometheus程序配置

mkdir {bin,cfg}
mv prometheus.yml cfg/
mv prometheus promtool bin/

配置环境变量

/etc/profile.d/prometheus.sh

#!/bin/bash
export PROMETHEUS_HOME=/usr/local/prometheus
export PATH=$PATH:${PROMETHEUS_HOME}/bin

使其生效

source /etc/profile.d/prometheus.sh 
chmod +x /etc/profile.d/prometheus.sh 

配置服务文件

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

[Unit]
Description=prometheus server project
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/prometheus/bin/prometheus --config.file=/usr/local/prometheus/cfg/prometheus.yml --storage.tsdb.path=/usr/local/prometheus/data
Restart=on-failure

[Install]
WantedBy=multi-user.target

设置服务开机自启动

systemctl enable prometheus
systemctl start prometheus

1.2:apt源安装

在apt源中也可以安装prometheus系列软件包,但是版本不是最新的。

root@control:~# apt list |grep prometheus

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

对于服务启动文件,有需要的可以参考apt安装后的服务启动文件

/lib/systemd/system/prometheus.service
/lib/systemd/system/prometheus-node-exporter.service

02:添加node_exporter监控端

在被监控的主机上安装node_exporter

wget https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz
tar -xf node_exporter-1.3.1.linux-amd64.tar.gz -C /usr/local
cd /usr/local
ln -s node_exporter-1.3.1.linux-amd64 node_exporter

自定义node_exporter程序配置

cd node_exporter
mkdir bin
mv node_exporter bin/

配置环境变量

/etc/profile.d/node_exporter.sh

#!/bin/bash
export NODE_EXPORTER_HOME=/usr/local/node_exporter
export PATH=$PATH:${NODE_EXPORTER_HOME}/bin

使其生效

source /etc/profile.d/node_exporter.sh 
chmod +x /etc/profile.d/node_exporter.sh 

配置服务文件

/usr/lib/systemd/system/node_exporter.service

[Unit]
Description=prometheus node exporter
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/node_exporter/bin/node_exporter
Restart=on-failure

[Install]
WantedBy=multi-user.target

设置服务开机自启动

systemctl enable node_exporter
systemctl start node_exporter

访问主机ip:9100/metrics查看效果

curl 192.168.31.11:9100/metrics

03:添加Job

这里的job类似于zabbix中的Host Groups

/usr/local/prometheus/cfg/prometheus.yml

... # 只配置scrape_config的内容
scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

  - job_name: "nodes"          # 组名
    metrics_path: '/metrics'   # 配置metrics的uri
    static_configs:
      - targets:               # groups中的host,列表形式
        - '192.168.31.11:9100'

重启prometheus服务查看

04:grafana部署

4.1:安装软件

官方地址:https://grafana.com/grafana/download?pg=get&plcmt=selfmanaged-box1-cta1

apt-get install -y adduser libfontconfig1
wget https://dl.grafana.com/enterprise/release/grafana-enterprise_8.4.4_amd64.deb
dpkg -i grafana-enterprise_8.4.4_amd64.deb

# 安装插件
grafana-cli plugins list-remote
grafana-cli plugins install grafana-piechart-panel
grafana-cli plugins ls

# 启动服务
systemctl start grafana-server.service
systemctl status grafana-server.service
systemctl enable grafana-server.service 

# 检查端口
ss -nutlp | grep "grafana"

使用浏览器访问3000端口,默认用户名密码admin/admin

4.2:添加数据源

Configuration -> datasources -> add your data source -> 选择prometheus

URL: http://localhost:9090/

4.3:导入模板

"+"号图标 -> Import

官方模板站点:https://grafana.com/grafana/dashboards/

这里我选用了8919和1860模板

https://grafana.com/grafana/dashboards/8919
https://grafana.com/dashboards/1860

4.4:查看效果

!> 如果没有图形,请查看主机和你浏览器的时间是否准确
