StackStorm简介:
故障自愈作为运维领域的热门话题之一,各个公司都会投入大量的人力来开发不同的组件,如何正确、有序的调用不同组件以及避免相同功能组件的开发,是一件亟待解决的问题。 StackStrom 是一个基于事件流并自动执行的系统框架,基于此,可以让 外部系统产生的事件,有序的、可编排的集合到一起,作为一个完整的事件流去执行,从而解决一些高频次的运维难题。
StackStorm的工作步骤大体如下:
1. StackStorm Sensor感应并触发事件。
2. Rules Engine对事件进行规则匹配,如果匹配产生任务。
3. StackStorm Worker执行任务,一般是调用到外部系统。
4. StackStorm记录审计任务执行的细节。
5.任务执行结果返回给Rules Engine进行进一步处理。
StackStorm部署步骤:以下操作,整理自官方部署步骤https://docs.stackstorm.com/install/rhel7.html
本次部署环境如下:
系统:Centos7.7
内存:4G(官方说2G内容也可,我部署的时候内容使用率大概在60%,所以2G应该也是勉强的)
磁盘:50G

浏览器访问服务器IP即可,在登录界面输入账号st2admin密码Ch@ngeMe,登录后界面如下
具体的使用方法,后续我再进行补充
