部署prometheus

1. 环境

主机	IP
监控机	192.168.72.141
被监控机	192.168.72.139

2. 部署

2.1 安装go环境

[root@master prometheus]# dnf -y install go
上次元数据过期检查：4:22:23 前，执行于 2021年11月24日 星期三 21时00分43秒。
依赖关系解决。
============================================
 软件包     架构   版本     仓库       大小
============================================
安装:
 golang     x86_64 1.17.2-2.module_el8.6.0+9

[root@master local]# go version
go version go1.17.2 linux/amd64

2.2安装prometheus

prometheus-2.31.1.linux-amd64.tar.gz

2.2.1 安装

[root@master src]# ls
apr-1.7.0
apr-1.7.0.tar.gz

apr-util  include  prometheus

2.2.2 启动

[root@master prometheus]# ./prometheus --config.file=/usr/local/prometheus/prometheus.yml &

2.2.3 验证

在这里插入图片描述

2.2.4 以服务的方式启动

[root@master prometheus]# cat /etc/systemd/system/prometheus.service
[Unit]
Description=Prometheus Monitoring System
Documentation=Prometheus Monitoring System
 
[Service]
ExecStart=/usr/local/prometheus/prometheus \
  --config.file=/usr/local/prometheus/prometheus.yml \
  --web.listen-address=:9090
Restart=on-failure
[Install]
WantedBy=multi-user.target

[root@master prometheus]# systemctl enable --now prometheus
Created symlink /etc/systemd/system/multi-user.target.wants/prometheus.service → /etc/systemd/system/prometheus.service.

[root@master prometheus]# ss -antl

2.3.1安装

[root@node1 ~]# cd /usr/src/
[root@node1 src]# ls
debug
haproxy-2.5.0
kernels
mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz

2.3.2验证

访问192.168.72.139:9100/metrics，若出现数据则服务开启成功

2.3.4设置node_exporter 以服务的方式启动并设置开机自启

[root@node1 node_exporter]# vim /etc/systemd/system/node_exporter.service
[root@node1 node_exporter]# cat /etc/systemd/system/node_exporter.service

2.4 修改Prometheus 配置，监控Linux机器

2.4.1修改Prometheus配置

进入Prometheus的安装文件夹，打开Prometheus配置文件

[root@master prometheus]# pwd
/usr/local/prometheus
[root@master prometheus]# ls
console_libraries  NOTICE
consoles           prometheus
data               prometheus.yml
LICENSE            promtool
[root@master prometheus]# vim prometheus.yml

在scrape_configs标签下，添加以下内容，配置监控

  - job_name: 'Linux'
    static_configs:
      - targets: ['192.168.72.139:9100']
        labels:
          instance: Linux

2.4.2重启访问

[root@master prometheus]# systemctl restart prometheus
