Prometheus监控物理服务器

一、Prometheus介绍

Prometheus(普罗米修斯)是一套开源的监控&报警&时间序列数据库的组合, 由go语言开发。适合监控容器平台, 因为kubernetes(俗称k8s)的流行带动了prometheus的发展。
PS：使用prometheus监控仍然监控物理服务器。

官方网站: https://prometheus.io/

二、Prometheus监控

实验环境准备

1、所有服务器静态ip(要求能上外网)，所有服务器各配置主机名并绑定

//各自配置好主机名
[root@stw ~]# hostnamectl set-hostname grafana.example.com
[root@stw ~]# bash
//三台都互相绑定IP与主机名
[root@grafana ~]# vim /etc/hosts

2、所有服务器时间同步(时间同步一定要做)

[root@client ~]# systemctl restart chronyd
[root@client ~]# systemctl enable chronyd
[root@client ~]# systemctl status firewalld.service

3、所有服务器关闭防火墙,selinux

[root@client ~]# systemctl status firewalld.service 
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@client ~]# getenforce 
Disabled

安装Prometheus

1、二进制版解压就能用，不需要编译

[root@prometheus ~]# rz -E
