一、Prometheus 安装脚本（最终完善版）

#!/bin/bashset-eecho"===== 开始安装 Prometheus ====="# 清理旧环境systemctl stop prometheus2>/dev/null systemctl disable prometheus2>/dev/nulluserdel-rprometheus2>/dev/nullrm-rf/usr/local/prometheus /var/lib/prometheus /etc/systemd/system/prometheus.service# 解压（已下载好包）tarzxf prometheus-2.19.2.linux-amd64.tar.gzmvprometheus-2.19.2.linux-amd64 /usr/local/prometheus# 创建用户groupaddprometheus2>/dev/nulluseradd-gprometheus-m-d/var/lib/prometheus-s/sbin/nologin prometheus2>/dev/null# 创建数据目录mkdir-p/var/lib/prometheus/datachown-Rprometheus:prometheus /usr/local/prometheus /var/lib/prometheus# 生成 systemdcat>/etc/systemd/system/prometheus.service<<EOF [Unit] Description=Prometheus After=network.target [Service] User=prometheus Group=prometheus ExecStart=/usr/local/prometheus/prometheus \ --config.file=/usr/local/prometheus/prometheus.yml \ --storage.tsdb.path=/var/lib/prometheus/data \ --web.listen-address=0.0.0.0:9090 Restart=on-failure LimitNOFILE=65536 [Install] WantedBy=multi-user.target EOF# 启动systemctl daemon-reload systemctlenableprometheus systemctl restart prometheusecho"===== Prometheus 安装完成 ====="systemctl status prometheus --no-pager

二、Node Exporter 安装脚本（最终完善版）

#!/bin/bashset-eecho"===== 开始安装 Node Exporter ====="# 清理旧环境systemctl stop node_exporter2>/dev/null systemctl disable node_exporter2>/dev/nullrm-rf/usr/local/node_exporter /etc/systemd/system/node_exporter.service# 解压tarzxf node_exporter-1.3.1.linux-amd64.tar.gzmvnode_exporter-1.3.1.linux-amd64 /usr/local/node_exporter# 用户不存在则创建idprometheus&>/dev/null||useradd-m-d/var/lib/prometheus-s/sbin/nologin prometheus# 权限chown-Rprometheus:prometheus /usr/local/node_exporter# systemdcat>/etc/systemd/system/node_exporter.service<<EOF [Unit] Description=Node Exporter After=network.target [Service] User=prometheus Group=prometheus ExecStart=/usr/local/node_exporter/node_exporter \ --web.listen-address=:9100 \ --collector.systemd \ --collector.processes Restart=on-failure [Install] WantedBy=multi-user.target EOF# 启动systemctl daemon-reload systemctlenablenode_exporter systemctl restart node_exporterecho"===== Node Exporter 安装完成 ====="systemctl status node_exporter --no-pager

三、Grafana 安装脚本（最终极简稳定版）

四、配套 prometheus.yml（最终完整版）

global:scrape_interval:15sevaluation_interval:15salerting:alertmanagers:-static_configs:-targets:['localhost:9093']rule_files:-"alerting_rules.yml"scrape_configs:-job_name:'prometheus'static_configs:-targets:['localhost:9090']-job_name:'node_exporter'static_configs:-targets:['localhost:9100']

Prometheus + Node Exporter + Grafana + 主配置 + 权限 + 数据目录 + systemd

给你CentOS7 专用 · 100% 可直接运行

三组件一键 Docker / Docker Compose 方案

Prometheus + Node Exporter + Grafana
干净、不污染系统、讲课最爽、博客最帅！

方案1：Docker Compose 一键启动（最推荐 ✅）

1）先装 docker + docker-compose（CentOS7）

#!/bin/bash# 安装 Dockeryuminstall-yyum-utils yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo yuminstall-ydocker-ce docker-ce-cli containerd.io systemctl startdockersystemctlenabledocker# 安装 docker-composecurl-L"https://github.com/docker/compose/releases/download/v2.20.0/docker-compose-$(uname-s)-$(uname-m)"-o/usr/local/bin/docker-composechmod+x /usr/local/bin/docker-compose

2）docker-compose.yml（完整最终版 ✅）

直接新建一个文件夹，放这个文件即可：

version:'3'services:# 1. Node Exporter (监控机器)node_exporter:image:prom/node-exporter:latestcontainer_name:node_exporterrestart:alwaysports:-"9100:9100"volumes:-/:/host:ro,rslavecommand:-'--path.rootfs=/host'network_mode:host# 2. Prometheus (数据存储+查询)prometheus:image:prom/prometheus:v2.19.2container_name:prometheusrestart:alwaysports:-"9090:9090"volumes:-./prometheus.yml:/etc/prometheus/prometheus.yml-prom_data:/prometheusnetwork_mode:host# 3. Grafana (可视化面板)grafana:image:grafana/grafana:10.1.5container_name:grafanarestart:alwaysports:-"3000:3000"volumes:-grafana_data:/var/lib/grafananetwork_mode:hostvolumes:prom_data:grafana_data:

3）配套 prometheus.yml（和上面放一起）

global:scrape_interval:15sscrape_configs:-job_name:'prometheus'static_configs:-targets:['localhost:9090']-job_name:'node_exporter'static_configs:-targets:['localhost:9100']

4）一键启动

docker-composeup-d

方案2：纯 Docker 命令版（无 compose）

直接复制运行 ✅

#!/bin/bash# 1. 启动 Node Exporterdockerrun-d\--namenode_exporter\--nethost\--restartalways\-v/:/host:ro,rslave\prom/node-exporter\--path.rootfs=/host# 2. 启动 Prometheusdockerrun-d\--nameprometheus\--nethost\--restartalways\-v./prometheus.yml:/etc/prometheus/prometheus.yml\prom/prometheus:v2.19.2# 3. 启动 Grafanadockerrun-d\--namegrafana\--nethost\--restartalways\grafana/grafana:10.1.5
