一、Prometheus安装部署

1.1 官网地址

https://prometheus.io/

1.2 下载相关应用

• prometheus
• pushgateway/node_exporter
• alertmanager

1.3 环境

hostname	ipaddr	用途
vms31	192.168.26.31	prometheus
vms10	192.168.26.10	k8s-master
vms11	192.168.26.11	k8s-node
vms12	192.168.26.12	k8s-node

1.4 上传相关应用到vms31

[root@vms31 ~]# cd /opt/
[root@vms31 opt]# rz -y
[root@vms31 opt]# ls
alertmanager-0.23.0.linux-amd64.tar.gz  node_exporter-1.2.2.linux-amd64.tar.gz  prometheus-2.30.3.linux-amd64.tar.gz  pushgateway-1.4.2.linux-amd64.tar.gz

1.5 安装配置prometheus

[root@vms31 opt]# tar xf prometheus-2.30.3.linux-amd64.tar.gz 
[root@vms31 opt]# cd prometheus-2.30.3.linux-amd64/
[root@vms31 prometheus-2.30.3.linux-amd64]# cp prometheus /usr/local/bin/
[root@vms31 prometheus-2.30.3.linux-amd64]# vim prometheus.yml
...
  # 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: ["192.168.26.31:9090"]
  # 使用pushgateway模块获取
  - job_name: "pushgateway"
    static_configs:
      - targets: ["192.168.26.31:9091"]
        labels:
          instance: pushgateway
  # 使用node exporter模块获取
  - job_name: "node exporter"
    static_configs:
      - targets: ["192.168.26.31:9100","192.168.26.10:9100","192.168.26.11:9100","192.168.26.12:9100"]

1.6 安装pushgateway

[root@vms31 opt]# cd /opt/
[root@vms31 opt]# tar xf pushgateway-1.4.2.linux-amd64.tar.gz

1.7 安装AlertManager

[root@vms31 pushgateway-1.4.2.linux-amd64]# cd /opt/
[root@vms31 opt]# tar xf alertmanager-0.23.0.linux-amd64.tar.gz 

1.8 安装node exporter

[root@vms31 opt]# cd /opt/
[root@vms31 opt]# tar xf node_exporter-1.2.2.linux-amd64.tar.gz 

1.9 将node exporter拷贝到其它设备并设置开机启动

for ip in 192.168.26.10 192.168.26.11 192.168.26.12; do scp node_exporter $ip:/usr/local/sbin/;done
[root@vms31 system]# vim /usr/lib/systemd/system/node_exporter.service 
[Unit]
Description=node_exporter
After=network.target

[Service]
ExecStart=/usr/local/sbin/node_exporter

for ip in 192.168.26.10 192.168.26.11 192.168.26.12; do scp /usr/lib/systemd/system/node_exporter.service $ip:/usr/lib/systemd/system/node_exporter.service;done
systemctl enable --now node_exporter

1.10 启动Prometheus和pushgateway

[root@vms31 ~]# cd /opt/prometheus-2.30.3.linux-amd64/
[root@vms31 prometheus-2.30.3.linux-amd64]# ./prometheus --config.file=promeths.yml &> ./prometheus.log &
