使用docker的方式部署
1. 创建项目目录
[root@129 ~]# mkdir /home/prometheus/
2.编写yml文件
[root@129 ~]# cd /home/prometheus/
[root@129 prometheus]# cat docker-compose.yml
version: "3"
services:
node-exporter:
image: prom/node-exporter
container_name: node-exporter
restart: always
privileged: true
environment:
- TZ=Asia/Shanghai
ports:
- 9100:9100
volumes:
- /proc:/host/proc
- /sys:/host/sys
- /:/rootfs
prometheus:
image: prom/prometheus
container_name: prometheus
restart: always
privileged: true
environment:
- TZ=Asia/Shanghai
ports:
- 9090:9090
volumes:
- /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml
grafana:
image: grafana/grafana
container_name: grafana
restart: always
privileged: true
environment:
- TZ=Asia/Shanghai
ports:
- 3000:3000
volumes:
- /opt/grafana-storage:/var/lib/grafana
# node-exporters主要是做系统数据收集，可以通过它监控到服务器的CPU、内存、磁盘、I/O等信息
3. 新建目录 prometheus，编辑配置文件 prometheus.yml
mkdir /opt/prometheus
cd /opt/prometheus/
vim prometheus.yml
内容如下：
global:
scrape_interval: 30s
evaluation_interval: 30s
scrape_configs:
- job_name: prometheus
static_configs:
- targets: ['localhost:9090']
labels:
instance: prometheus
- job_name: node-exporter
static_configs:
- targets: ['192.168.78.129:9100']
labels:
instance: localhost
4. 新建空文件夹grafana-storage，用来存储数据
mkdir /opt/grafana-storage
chmod 777 -R /opt/grafana-storage
5. 启动
[root@129 prometheus]# cd /home/prometheus/
[root@129 prometheus]# docker-compose up -d --build
......
# 如果遇到这个报错 ERROR: Failed to Setup IP tables: Unable to enable SKIP DNAT rule，重启一下docker
# 会看到三个容器都已经运行起来了
[root@129 prometheus]# docker ps

查看 node-exporters，直接本机浏览器访问 http://192.168.78.129:9100/metrics
会发现已经监控到了本机的相关信息
查看 Prometheus http://192.168.78.129:9090/
登录 grafana http://192.168.78.129:3000/
初始账号和密码都是admin
创建数据源
选择添加—>然后选择Prometheus
点击 save&test
导入grafana 模板
推荐11074号模板，也可以去grafana官网选择 tps://grafana.com/grafana/dashboards?dataSource=prometheus
发现本机的一些指标都已经自动监控了
也可以针对其他的服务器进行监控
