部署安装prometheus pushgateway

1. 下载安装包
   官方下载地址：https://prometheus.io/download/
   下载历史版本：https://github.com/prometheus/pushgateway/releases
   wget https://github.com/prometheus/pushgateway/releases/download/v1.4.2/pushgateway-1.4.2.linux-amd64.tar.gz
   
   
2. 解压安装
   tar -xf pushgateway-1.4.2.linux-amd64.tar.gz  -C /data/app
   mv /data/app/pushgateway-1.4.2.linux-amd64/ /data/app/pushgateway
3. 创建用户
   

   groupadd prometheus

   useradd prometheus -g prometheus -M -s /sbin/nologin

1. 编写服务启动脚本
   

   vim /usr/lib/systemd/system/pushgateway.service
   [Unit]
   Description=pushgateway
   Documentation=https://prometheus.io/
   After=network.target

   [Service]
   Type=simple
   User=prometheus
   ExecStart=/data/app/pushgateway/pushgateway
   Restart=on-failure

   [Install]
   WantedBy=multi-user.target

2. 服务开机自启动
   systemctl daemon-reload
   systemctl start pushgateway.service
   systemctl status pushgateway.service
   systemctl enable pushgateway.service
   systemctl is-enabled pushgateway.service

 

修改prometheus

cd prometheus
vim cfg/prometheus.yml

- job_name: 'pushgateway'
    static_configs:
    - targets: ['master.prometheus:9091']

 

重点：添加完配置之后重启prometheus服务才生效
