Prometheus 服务器

Prometheus Server 是 Prometheus组件中的核心部分，负责实现对监控数据的获取，存储以及查询。

NodeExporter 业务数据源

业务数据源通过 Pull/Push 两种方式推送数据到 Prometheus Server。

AlertManager 报警管理器

Prometheus 通过配置报警规则，如果符合报警规则，那么就将报警推送到 AlertManager，由其进行报警处理。

可视化监控界面

Prometheus 收集到数据之后，由 WebUI 界面进行可视化图标展示。目前我们可以通过自定义的 API 客户端进行调用数据展示，也可以直接使用 Grafana 解决方案来展示

简单地说，Prometheus 的实现架构也并不复杂。其实就是收集数据、处理数据、可视化展示，再进行数据分析进行报警处理。 但其珍贵之处在于提供了一整套可行的解决方案，并且形成了一整个生态，能够极大地降低我们的研发成本。

一、Prometheus安装与部署

1.1、go环境部署

首先安装运行环境go
有网络环境直接运行下面命令行
yum -y install go
无网络离线安装
下载go的安装包
Golang官网下载地址：https://golang.org/dl/
按照包版本：go1.18.2.linux-amd64.tar.gz
将安装包解压放到到usr/local中，并解压

[root@shigj ~]# vim /etc/profile
export PATH=$PATH:/usr/local/go/bin
[root@shigj ~]# source /etc/profile
[root@shigj ~]# go version
go version go1.18 linux/amd64

1.2、安装普罗米修斯prometheus

开始安装prometheus，首先先去官网下载对应系统的版本
https://prometheus.io/download/ 解压并重命名

[root@shigj local]# tar -zxvf prometheus-2.35.0.linux-amd64.tar.gz
[root@shigj local]# mv prometheus-2.35.0.linux-amd64 prometheus

切换到目录下

[root@shigj local]# cd prometheus/
[root@shigj prometheus]# ls
console_libraries  consoles  LICENSE  NOTICE  prometheus  prometheus.yml  promtool

接着要配置一下监控的配置文件：prometheus.yml
localhost修改为IP地址
启动 prometheus服务

[root@shigj prometheus]# /usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml &
[1] 25131

表示成功

添加服务并设置开机启动

[root@shigj prometheus]# pwd
/usr/local/prometheus
[root@shigj prometheus]# touch /usr/lib/systemd/system/prometheus.service
[root@shigj prometheus]# vim /usr/lib/systemd/system/prometheus.service

[Install]
WantedBy=multi-user.target
[root@shigj prometheus]# systemctl daemon-reload
[root@shigj prometheus]# systemctl enable prometheus.service
Created symlink /etc/systemd/system/multi-user.target.wants/prometheus.service → /usr/lib/systemd/system/prometheus.service.

[root@shigj prometheus]# systemctl start prometheus.service
[root@shigj prometheus]# systemctl status prometheus.service

浏览器打开IP:9090端口即可打开普罗米修斯自带的监控页面

二、安装常用监控exporter

2.1、安装并启动

下载安装包并解压缩
https://prometheus.io/download/

[root@shigj ~]# du -sh node_exporter-1.3.1.linux-amd64.tar.gz 
6.7M	node_exporter-0.17.0.linux-amd64.tar.gz
[root@shigj ~]# mv node_exporter-1.3.1.linux-amd64.tar.gz /usr/local/
[root@shigj ~]# cd /usr/local/
[root@shigj local]# tar -zxvf node_exporter-1.3.1.linux-amd64.tar.gz 
node_exporter-1.3.1.linux-amd64/
node_exporter-1.3.1.linux-amd64/NOTICE
node_exporter-1.3.1.linux-amd64/node_exporter
node_exporter-1.3.1.linux-amd64/LICENSE

启动 node_exporter 服务

[root@shigj node_exporter]# ./node_exporter &

添加服务并设置开机启动

[root@shigj node_exporter]# touch /usr/lib/systemd/system/node_exporter.service
[root@shigj node_exporter]# vim /usr/lib/systemd/system/node_exporter.service
[Unit]
Description=prometheus server daemon
[Service]
ExecStart=/usr/local/node_exporter/node_exporter
Restart=on-failure
[Install]
WantedBy=multi-user.target
[root@shigj node_exporter]# systemctl daemon-reload
[root@shigj node_exporter]# systemctl enable node_exporter.service
[root@shigj node_exporter]# systemctl start node_exporter.service
[root@shigj node_exporter]# systemctl status node_exporter.service

node 监控的端口是9100

然后需要配置prometheus 的yml文件

重启主机prometheus

[root@shigj prometheus]# systemctl stop prometheus.service
[root@shigj prometheus]# systemctl start prometheus.service

三、Grafana

3.1、准备

下载地址
https://grafana.com/grafana/download (prometheus)默认的页面可能没有那么直观，我们可以安装grafana使监控看起来更直观
wget https://dl.grafana.com/enterprise/release/grafana-enterprise-8.5.2-1.x86_64.rpm
国外网址科学上网或许下载快一些

3.2、安装

[root@shigj local]# yum localinstall grafana-enterprise-8.5.2-1.x86_64.rpm

[root@shigj local]# /sbin/chkconfig --add grafana-server
[root@shigj local]# service grafana-server start
Starting grafana-server (via systemctl):                   [  OK  ]

启动后访问地址：ip:3000(记得开放3000端口)
初始用户名和密码都是admin
如果出现密码忘记怎么办？？
重置密码下面命令行即可重置成功，密码为admin123

[root@openvpn bin]# ./grafana-cli admin reset-admin-password admin123
