1.环境说明

角色 主机名 IP 系统版本
监控服务端 sy-gmh-monitor-vm6.shaoyan.pro 192.168.168.6 CentOS Linux release 7.6.1810 (Core)

计划prometheus，zabbix，saltstack服务端都跑在这台虚拟机。

2.下载安装prometheus

到官网链接下载对应系统版本：https://prometheus.io/download/
因为prometheus是Go写的，提供的是编译好的二进制包，所以下载解压，添加环境变量就可以用啦。

  1. [root@sy-gmh-monitor-vm6:/data/app]# wget https://github.com/prometheus/prometheus/releases/download/v2.10.0/prometheus-2.10.0.linux-amd64.tar.gz
  2. [root@sy-gmh-monitor-vm6:/data/app]# mv prometheus-2.10.0.linux-amd64 prometheus-2.10.0
  3. [root@sy-gmh-monitor-vm6:/data/app]# ln -s /data/app/prometheus-2.10.0 /usr/local/prometheus
  4. [root@sy-gmh-monitor-vm6:/data/app]# tail -2 /etc/profile.d/myenv.sh 
  5. # prometheus
  6. export PATH=/usr/local/prometheus:$PATH
  7. [root@sy-gmh-monitor-vm6:/data/app]# source /etc/profile.d/myenv.sh

3.启动prometheus

  1. # 使用默认配置先跑起来
  2. [root@sy-gmh-monitor-vm6:~]# prometheus --config.file "/usr/local/prometheus/prometheus.yml"
  4. # 再开一个ssh连接。查看端口，添加iptables防火墙规则
  5. [root@sy-gmh-monitor-vm6:~]# netstat -nltp
  6. Active Internet connections (only servers)
  7. Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
