搭建prometheus- grafana 之 自动化安装Prometheus+node 并注册为系统服务 + 基础 grafana模板导入使用

# 安装Prometheus

#!/bin/bash

# 防止报错先 删除用户和目录
userdel prometheus
rm -rf /var/lib/prometheus
rm -rf /usr/local/prometheus/



#下载解压
#wget https://github.com/prometheus/prometheus/releases/download/v2.19.2/prometheus-2.19.2.linux-amd64.tar.gz
tar zxvf prometheus-2.12.0.linux-amd64.tar.gz
mv prometheus-2.12.0.linux-amd64 /usr/local/prometheus

#创建用户
groupadd prometheus
useradd -g prometheus -m -d /var/lib/prometheus -s /sbin/nologin prometheus
