如何安装prometheus请参考我博客

ubuntu2404安装prometheus监控软件-CSDN博客

1.发行版本

系统/软件	版本号	备注
ubuntu	Ubuntu 22.04.5 LTS	lsb_release -a
nginx	nginx/1.18.0	nginx -V
nginx-prometheus-exporter	version 1.4.1	./nginx-prometheus-exporter --version

2.安装过程,要监控nginx关键一步就是要把stub_status打开

查看nginx是否支持 stub_status命令,另外不需要重新编译nginx

nginx -V

#查看是否有--with-http_stub_status_module

#安装nginx
apt install nginx -y
systemctl enable --now nginx

#配置stub_status

vim /etc/nginx/sites-enabled/default


server {
    listen 80;
    server_name localhost;  # 或者是你的域名

    location /nginx_status {
        stub_status on;
        access_log off;
        #allow 127.0.0.1;    # 允许本地访问
        #deny all;            # 拒绝其他IP访问
    }
}

#重载nginx
nginx -s reload
nginx -t #查看配置文件
curl http://127.0.0.1/nginx_status
#或者直接网页查看

3.安装nginx-prometheus-exporter

#新建/usr/local/nginx-prometheuse-exporter 目录
mkdir /usr/local/nginx-prometheuse-exporter
cd /usr/local/nginx-prometheuse-exporter
wget https://github.com/nginx/nginx-prometheus-exporter/releases/download/v1.4.1/nginx-prometheus-exporter_1.4.1_linux_amd64.tar.gz
tar xvzf nginx-prometheus-exporter_1.4.1_linux_amd64.tar.gz

#新建安装服务
vim /usr/lib/systemd/system/nginx-prometheus-exporter.service

[Unit]
Description=nginx-prometheus-exporter
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/nginx-prometheuse-exporter  --nginx.scrape-uri=http://127.0.0.1/nginx_status
Restart=on-failure

[Install]
WantedBy=multi-user.target

#部署服务

systemctl daemon-reload
systemctl enable  nginx-prometheus-exporter
systemctl start  nginx-prometheus-exporter
systemctl status  nginx-prometheus-exporter

4.添加指标到prometheus,-job需要格式对齐

#添加个节点
vim /usr/local/prometheus/prometheus.yml 

- job_name: 'nginx' # 添加node配置
    static_configs:
      - targets:
        - '192.168.60.244:9113' #192.168.60.244换成你的ip地址
