一，物理节点安装配置（简单配置，未涉及报警及grafana图形展示）

1，prometheus 官网下载安装

下载安装

# pwd

/usr/local/src

https://github.com/prometheus/prometheus/releases/download/v2.12.0/prometheus-2.12.0.linux-amd64.tar.gz

# tar xvf prometheus-2.11.1.linux-amd64.tar.gz

# ln -sv /usr/local/src/prometheus-2.11.1.linux-amd64 /usr/local/prometheus

# cd /usr/local/prometheus

服务启动脚本

# vim /etc/systemd/system/prometheus.service

[Unit]

Description=Prometheus Server

Documentation=https://prometheus.io/docs/introduction/overview/

After=network.target

[Service]

Restart=on-failure

WorkingDirectory=/usr/local/prometheus/

ExecStart=/usr/local/prometheus/prometheus --

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

[Install]

WantedBy=multi-user.target

配置所监控的node

cd /usr/local/prometheus

# grep -v "#" prometheus.yml | grep -v "^$"

global:

alerting:

  alertmanagers:

  - static_configs:

    - targets:

rule_files:

scrape_configs:

  - job_name: 'prometheus'

    static_configs:

    - targets: ['localhost:9090']

  - job_name: 'promethues-node'

    static_configs:

    - targets: ['192.168.7.110:9100','192.168.7.111:9100']

修改配置文件后需要重启服务

启动

# systemctl daemon-reload

# systemctl restart prometheus

# systemctl enable prometheus

查看端口是否监听正常

2,节点安装

# pwd

/usr/local/src

https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

# tar xvf node_exporter-0.18.1.linux-amd64.tar.gz

# ln -sv /usr/local/src/node_exporter-0.18.1.linux-amd64 /usr/local/node_exporter

# cd /usr/local/node_exporter

启动脚本

# vim /etc/systemd/system/node-exporter.service

[Unit]

Description=Prometheus Node Exporter

After=network.target

[Service]

ExecStart=/usr/local/node_exporter/node_exporter

[Install]

WantedBy=multi-user.target

启动

# systemctl daemon-reload

# systemctl restart node-exporter

# systemctl enable node-exporter

查看端口是否监听正常，关闭防火墙和selinxu
