Linux安装OpenStack Exporter

Github项目地址：项目地址：https://github.com/openstack-exporter/openstack-exporter

一、安装Docker

1、配置docker源

[root@controller ~]# yum -y install yum-utils device-mapper-persistent-data lvm2

[root@controller ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2、安装docker

[root@controller ~]# yum -y install docker-ce docker-ce-cli containerd.io

3、启动docker并配置开机自启动

[root@controller ~]# systemctl enable docker

[root@controller ~]# systemctl start docker

二、安装OpenStack Exporter

1、编辑clouds.yaml

[root@controller ~]# mkdir -p /etc/openstack

[root@controller ~]# vim /etc/openstack/clouds.yaml

clouds:
  default:
    region_name: RegionOne
    interface: public
    identity_api_version: 3
    auth:
      auth_url: http://controller:5000/v3
      username: admin
      password: admin
      project_name: admin
      user_domain_name: 'Default'
      project_domain_name: 'Default'
    verify: true

 2、启动OpenStack Exporter容器

[root@controller ~]# docker run -d -p 9180:9180 --name openstack-exporter -v /etc/openstack/clouds.yaml:/etc/openstack/clouds.yaml --add-host controller:192.168.10.170 ghcr.io/openstack-exporter/openstack-exporter:latest --prefix="openstack" --endpoint-type="public" default

3、查看容器运行状态

[root@controller ~]# docker ps -a

三、安装Pormetheus

1、创建Prometheus工作目录

[root@controller ~]# mkdir -p /data/prometheus/{data,config,rules}

[root@controller ~]# chmod 777 /data/prometheus/data

2、创建Prometheus配置文件

[root@controller ~]# vim /data/prometheus/config/prometheus.yml

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.

alerting:
  alertmanagers:
    - static_configs:
      - targets:
        - "192.168.10.170:9093"

rule_files:
  - 'rules/*.yml'

scrape_configs:
  # The job name is added as a label  to any timeseries scraped from this config.
  - job_name: "prometheus"
    static_configs:
      - targets:
        - "192.168.10.170:9090"
        labels:
          app: "prometheus"

  - job_name: "openstack-exporter"
    scrape_interval: 30s
    static_configs:
      - targets:
        - "192.168.10.170:9180"

 3、启动Prometheus容器

[root@controller ~]# docker run -d \

  --name prometheus \

  -p 9090:9090 \

  -v /data/prometheus/config/prometheus.yml:/etc/prometheus/prometheus.yml \

  -v /data/prometheus/data:/prometheus \

  -v /data/prometheus/rules:/etc/prometheus/rules \

  --restart=unless-stopped \

  prom/prometheus:latest \

  --web.enable-lifecycle \

  --config.file=/etc/prometheus/prometheus.yml \

  --storage.tsdb.path=/prometheus \

  --storage.tsdb.retention.time=15d

4、查看容器运行状态

[root@controller ~]# docker ps -a

5、查看Prometheus的target
