1. 解压
2. tar -zxvf nginx-1.14.2.tar.gz

把nginx-vts-exporter放到nginx路径

1. cd usr/local/nginx-1.14.2
2. ./configure --prefix=/usr/local/nginx --add-module=usr/local/nginx-module-vts-master/
3. 注意：注意prefix=/usr/local/nginx意思是安装位置为/usr/local/nginx文件夹
4. make install

修改conf文件

http {
    vhost_traffic_status_zone;
    vhost_traffic_status_filter_by_host on;
 
...
 
server {
 
    ...
 
    location /status {
        vhost_traffic_status_display;
        vhost_traffic_status_display_format html;
    }
}

启动

1. cd /usr/local/nginx/sbin
2. ./nginx

访问http://ip/status出现以下显示则安装成功

四.配置Prometheus

修改/usr/local/prometheus-2.17.1.linux-amd64/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:
  alertmanagers:
  - static_configs:
    - 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'
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'nginx'
    static_configs:
      - targets: ['ip:9913']
