Prometheus 安装部署

一、监控简介

二、环境准备

1、服务器配置情况

服务器	ip	配置	内核版本	软件安装情况
node-01-server	192.168.163.130	2核4G	3.10	prometheus node_exporter grafana go
node-02-client	192.168.163.131	2核4G	3.10	node_exporter

2、软件下载地址

Prometheus：https://prometheus.io/download/#prometheus.

Go：https://studygolang.com/dl/golang/go1.17.5.linux-amd64.tar.gz

Grafana：https://dl.grafana.com/oss/release/grafana-5.4.2-1.x86_64.rpm

node_exporter：https://prometheus.io/download/#prometheus

3、环境准备

# 设置主机名
$ hostnamectl set-hostname node-01-server
$ hostnamectl set-hostname node-02-client 
# systecmctl stop firewalld && systemctl disable firewalld  # 防火墙关闭
# setenforce && sed -i 's/enforcing/disabled/' /etc/selinux/config # selinus关闭

三、具体安装

1、安装go环境

[root@node-01-server ~]# tar -xf go1.17.5.linux-amd64.tar.gz -C /usr/local/
[root@node-01-server ~]# ll /usr/local/ | grep go 
drwxr-xr-x  10 root root 257 Dec  9 21:50 go
[root@node-01-server ~]# vim /etc/profile
export PATH=$PATH:/usr/local/go/bin/  # 为了方便调用，我们在/etc/profile下对其进行定义路径，添加在最后一行。
[root@node-01-server ~]# source /etc/profile
[root@node-01-server ~]# go version 
go version go1.17.5 linux/amd64

2、安装prometheus

[root@node-01-server ~]# tar -xf prometheus-2.32.1.linux-amd64.tar.gz -C /usr/local/
[root@node-01-server ~]# mv /usr/local/prometheus-* /usr/local/Prometheus
[root@node-01-server ~]# ll /usr/local/Prometheus/
total 193448

3、安装export监控主机

[root@node-02-client Prometheus]# cd
[root@node-02-client ~]# tar -xf node_exporter-1.3.1.linux-amd64.tar.gz -C /usr/local/
[root@node-02-client ~]# cd /usr/local/node_exporter-1.3.1.linux-amd64/
[root@node-02-client ~]# ll
total 17820

## 通过server端的普鲁米修斯的界面，我们看到原本是红色down状态的node-02，变成up状态

4、安装grafana

[root@node-01-server ~]# yum -y install grafana-5.4.2-1.x86_64.rpm 
[root@node-01-server ~]# systemctl start grafana-server.service
[root@node-01-server ~]# systemctl enable grafana-server.service
[root@node-01-server ~]# ss -anptu  | grep grafana
