- 1.安装prometheus（hadoopm01）
- 上传prometheus压缩包，解压到/opt/module目录下
tar -zxvf prometheus-2.34.0.linux-amd64.tar.gz -C /opt/module - 修改目录名
mv prometheus-2.34.0.linux prometheus-2.34.0 - 修改配置文件 prometheus.yml
# my global config
global:
scrape_interval: 25s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 25s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration

# – “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=` to any timeseries scraped from this config.
– job_name: “prometheus”
# metrics_path defaults to ‘/metrics’
# scheme defaults to ‘http’.

static_configs:
– targets: [‘hadoops06:9100’]
– job_name: “node_export_hadoops05”
static_configs:
– targets: [‘hadoops07:9100’] - 启动prometheus
nohup ./prometheus –config.file=prometheus.yml > ./prometheus.log 2>&1 & - 启动后访问url hadoopm01:9090 即可看见promethues监控界面
- 上传prometheus压缩包，解压到/opt/module目录下
- 2.安装Node Exporter（每台机器）
- （每台机器）上传Node_exporter压缩包，解压到/opt/module目录下
tar -zxvf node_exporter-1.3.1.linux-amd64.tar.gz -C /opt/module - 修改文件夹名称
mv node_exporter-1.3.1.linux node_exporter-1.3.1 - 设置开机自启动
- 创建service文件
sudo vim /usr/lib/systemd/system/node_exporter.service - service 文件内容如下
[Unit]
Description=node_export

Restart=on-failure
[Install]
WantedBy=multi-user.target - sudo systemctl enable node_exporter.service
- sudo systemctl start node_exporter.service
- 创建service文件
- （每台机器）上传Node_exporter压缩包，解压到/opt/module目录下
- 3.安装grafana (hadoopm02)
- 上传并解压grafana的压缩包
sudo tar -zxvf grafana-enterprise-10.1.2.linux-amd64.tar.gz -C /opt/module/ - 进入grafana文件夹下
cd grafana-10.1.2/
nohup ./bin/grafana-server web > ./grafana.log 2>&1 & - 访问Web UI : 网页端输入 hadoopm02:3000
