解决方案介绍

该解决方案帮助您在华为云上基于弹性云服务器 ECS和云数据 GaussDB(for Influx)快速部署开源运维监控系统Prometheus。GaussDB(for Influx) 是一款采用计算存储分离架构,兼容InfluxDB生态的云原生时序数据库,提供高性能读写、高压缩率、冷热分层存储以及弹性扩容、监控告警等服务能力。

方案架构

架构描述

该解决方案会部署如下资源:

  • 创建一套云数据库 GaussDB(for Influx)实例,用于保存时序数据;
  • 创建一台弹性云服务器 ECS,用于安装部署普罗米修斯平台。 此外,您可以通过使用云监控服务来监测弹性云服务器运行状态;通过购买云备份服务,对弹性云服务器进行数据备份。

开始使用

安全组规则修改(可选)

[须知]

  • 该解决方案使用22端口用来远程登录弹性云服务器 ECS,默认对该方案创建的VPC子网网段放开,请参考修改安全组规则,配置IP地址白名单,以便能正常访问服务。

安全组实际是网络流量访问策略,包括网络流量入方向规则和出方向规则,通过这些规则为安全组内具有相同保护需求并且相互信任的云服务器、云容器等实例提供安全保护。如果您的实例关联的安全组策略无法满足使用需求,比如需要添加、修改、删除某个TCP端口,请参考以下内容进行修改。

  • 添加安全组规则:根据业务使用需求需要新开放某个TCP端口,请参考添加安全组规则添加入方向规则,打开指定的TCP端口。

  • 修改安全组规则:安全组规则设置不当会造成严重的安全隐患。您可以参考修改安全组规则,来修改安全组中不合理的规则,保证云服务器等实例的网络安全。

  • 删除安全组规则:当安全组规则入方向、出方向源地址/目的地址有变化时,或者不需要开放某个端口时,您可以参考删除安全组规则进行安全组规则删除。。 验证prometheus

5.登录GaussDB(for Influx)数据库。在命令行输入以下命令:

cd /usr/local/influxdb-1.7.9-1/

./influx -username 'rwuser' -password '管理员密码' -host 负载均衡地址 -port 8635

use prometheus

show measurements
