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。

[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
[root@sy-gmh-monitor-vm6:/data/app]# mv prometheus-2.10.0.linux-amd64 prometheus-2.10.0
[root@sy-gmh-monitor-vm6:/data/app]# ln -s /data/app/prometheus-2.10.0 /usr/local/prometheus
[root@sy-gmh-monitor-vm6:/data/app]# tail -2 /etc/profile.d/myenv.sh 
# prometheus
export PATH=/usr/local/prometheus:$PATH
[root@sy-gmh-monitor-vm6:/data/app]# source /etc/profile.d/myenv.sh

3.启动prometheus

# 使用默认配置先跑起来
[root@sy-gmh-monitor-vm6:~]# prometheus --config.file "/usr/local/prometheus/prometheus.yml"

# 再开一个ssh连接。查看端口，添加iptables防火墙规则
[root@sy-gmh-monitor-vm6:~]# netstat -nltp
