普罗米修斯安装部署（Prometheus+grafana+node_exporter）

Prometheus安装

安装go、wget

yum -y install go

yum -y install wget

下载Prometheus

cd  /usr/local

wget https://github.com/prometheus/prometheus/releases/download/v2.45.4/prometheus-2.45.4.linux-amd64.tar.gz

tar -zxvf  prometheus-2.45.4.linux-amd64.tar.gz

mv   prometheus-2.45.4.linux-amd64   prometheus

cd    prometheus

vi prometheus.yml

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
        - targets:
          # - alertmanager:9093


# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["192.168.40.176:9090"]
  - job_name: "主机地址"
    static_configs:
      - targets: ["192.168.xx.177:9100","192.168.xx.178:9100","192.168.xx.179:9100","192.168.xx.180:9100","192.168.xx.181:9100","192.168.xx.182:9100"]

运行Prometheus

/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml

关闭Prometheus

pkill prometheus

添加服务并设置开机启动

vi  /usr/lib/systemd/system/prometheus.service

[Unit]
Description=Prometheus
Documentation=https://prometheus.io/
After=network.target

[Service]
Type=simple
User=root
ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml
Restart=on-failure

[Install]
WantedBy=multi-user.target

systemctl daemon-reload

systemctl enable prometheus.service

pkill prometheus

systemctl start prometheus.service

systemctl status prometheus.service

验证：浏览器打开IP:9090端口

Grafana安装

下载-安装-启动-自动启动-查看端口

wget https://mirrors.aliyun.com/grafana/yum/rpm/Package/grafana-enterprise-10.1.0-1.x86_64.rpm

rpm -ivh grafana-enterprise-10.1.0-1.x86_64.rpm

systemctl start grafana-server

systemctl enable grafana-server

netstat -natp | grep :3000

验证

访问ip:3000 账户：admin 密码：admin

更换中文

vi /usr/share/grafana/conf/defaults.ini

将default_language = en-US改为 zh-Hans

添加Prometheus数据源

按要求输入被监控端地址

更换仪表盘

仪表盘下载地址https://grafana.com/grafana/dashboards

文件为.json结尾

上传加载即可

node_exporter安装（被监控端）

下载-解压-更名-开放端口-重新加载-生成目录-生成日志文件

cd /opt
wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz
tar -zxvf node_exporter-1.7.0.linux-amd64.tar.gz
mv node_exporter-1.7.0.linux-amd64  node_exporter
sudo firewall-cmd --add-port=9100/tcp --permanent
sudo firewall-cmd --reload
mkdir -p /applog/node_exporter/
touch /applog/node_exporter/node_exporter.log
cd node_exporter

编辑脚本-脚本文件-授权

[root@kvm1 node_exporter]# vi node_exporter.sh

#!/bin/bash
/opt/node_exporter/node_exporter &>> /applog/node_exporter/node_exporter.log

chmod +x node_exporter.sh

添加系统文件重置-自启动-启动-状态

vi /usr/lib/systemd/system/node_exporter.service

[Unit]
