MCollective安装配置

puppet agent 通过定时拉取的方式来更新本地系统,但无法满足实时更新的需求。 mcollective 通过 消息中间件 的方式,mclient/mservers通过消息的推送/订阅,实现mservers实时执行mclient提交的请求。(添加 m 说明是mcollective的组件!)

最新版的安装除了官网,没有其他可以直接学习的资料(只能参考)。先看官网的资料:

摘录官网安装描述:[Installing MCollective requires the following steps]

  • Make sure your middleware is up and running and your firewalls are in order.
  • Install the mcollective package on servers, then make sure the mcollective service is running.
  • Install the mcollective-client package on admin workstations.
  • Most Debian-like and Red Hat-like systems can use the official Puppet Labs packages. Enable the Puppet Labs repos, or import the packages into your own repos.
    • If you’re on Debian/Ubuntu, mind the missing package dependency.
  • If your systems can’t use the official packages, check the system requirements and either build your own or run from source.

mcollective对于puppet来说是一个锦上添花的组件,没有puppet一样正常运转。部署主要由两个部分组成:

  • 部署消息中间件
  • 配置mcollective(puppet4.4 agent已经安装该功能,redhat也自带装了Stomp包:/opt/puppetlabs/puppet/lib/ruby/gems/2.1.0/gems/ 目录下面)
    • 配置mclient/mserver
    • 配置Stomp with TLS
    • 配置security

本文先简单实现连接远程主机,然后配置安全功能,最后用puppet来重新实现 mcollective 的安装和配置。

环境说明

  • hadoop-master2:
    • 172.17.42.1
    • puppetserver, activemq-server, mcollective-client
  • hadoop-master1/hadoop-slaver1/hadoop-slaver2:
    • 172.17.0.2/¾
    • puppet-agent, mcollective-server

ActiveMQ部署

activemq的服务端是一个spring-jetty项目,直接解压运行启动脚本即可。

On Unix:
From a command shell, change to the installation directory and run ActiveMQ as a foregroud process:
cd [activemq_install_dir]/bin
./activemq console
From a command shell, change to the installation directory and run ActiveMQ as a daemon process:

简单配置(unencrypted Stomp)

安装puppet4.4后,mcollective已经安装好了!直接修改配置连接到activemq即可。

自带的插件功能比较少,要真正把 mcollective 用起来需要安装插件:puppet, service, package等等。这篇主要记录安装过程,插件安装以及使用后面具体实践了再写。

我觉得内网生产环境安装,到这一步已经差不多了!下面的安全配置就当深入学习吧。

SSL Security plugin

Stomp with TLS (安全传输层协议)用于加密数据。而 security plugin 主要功能有:

  • mcollective server要授权才会执行 client 发送的请求。
  • create a token that uniquely identify the client - based on the filename of the public key。
  • 在请求中添加创建时间和TTL保证数据的完整性(不被拦截、篡改以及重复)。
