Puppet运维实战

foreman架构的引入7-Foreman结合mcollective完成push动作

注：以下内容是在foreman1.6.3+puppet2.6.2环境下进行操作。更多配置请参考官网http://theforeman.org/manuals/1.6/index.html

在foreman-proxy的1.6.3版本，至少提供了以下五种触发puppet agent命令的工具，默认使用的是puppetrun，不过已经过时，这里介绍如何使用mcollective进行触发，下个章节会介绍如何使用puppetssh触发。

#   puppetrun   (for puppetrun/kick, deprecated in Puppet 3)
#   mcollective (uses mco puppet)
#   puppetssh   (run puppet over ssh)
#   salt        (uses salt puppet.run)
#   customrun   (calls a custom command with args)

在整个测试之前，首先要保障你的mco+mq在命令行操作的情况下是OK的。如果没有OK或者不懂什么是mco+mq，请参考之前的文章。

如何是OK的？如下：

[root@puppetmaster162 yum.repos.d]# mco puppet -v runonce
Discovering hosts using the mc method for 2 second(s) .... 1

 * [ ============================================================> ] 1 / 1


puppetmaster162.kisspuppet.com          : OK
    {:summary=>      "Started a Puppet run using the 'puppet agent --test --color=false --splay --splaylimit 30' command"}

1、在Foreman中开启puppet插件的puppetrun功能

Foreman安装

Foreman安装

2、配置foreman-proxy代理的puppet的puppet_provider

[root@puppetmaster162 ~]# vim /etc/foreman-proxy/settings.d/puppet.yml 
---
# Puppet management
:enabled: true
:puppet_conf: /etc/puppet/puppet.conf
# valid providers:
#   puppetrun   (for puppetrun/kick, deprecated in Puppet 3)
#   mcollective (uses mco puppet)
#   puppetssh   (run puppet over ssh)
#   salt        (uses salt puppet.run)
#   customrun   (calls a custom command with args)
:puppet_provider: mcollective
...

3、配置sudoer，添加mco命令

[root@puppetmaster162 ~]# vim /etc/sudoers.d/foreman-proxy 

foreman-proxy ALL = NOPASSWD : /usr/bin/puppet cert *, /usr/bin/mco puppet runonce *
Defaults:foreman-proxy !requiretty

[root@puppetmaster162 ~]# /etc/init.d/foreman-proxy restart
Stopping foreman-proxy:                                    [  OK  ]
Starting foreman-proxy:                                    [  OK  ]

4、页面测试puppetrun按钮

Foreman安装

成功之后的显示

5、查看报告看更详细的信息

#可以通过日志查看执行情况
[root@puppetmaster162 yum.repos.d]# tailf  /var/log/foreman-proxy/proxy.log


192.168.20.11 - - [17/Dec/2014 16:25:36] "POST /run HTTP/1.1" 200 - 0.5454

以上

[root@puppetmaster162 ~]# cat /etc/foreman-proxy/settings.yml
...
:log_file: /var/log/foreman-proxy/proxy.log
# valid options are
# WARN, DEBUG, Error, Fatal, INFO, UNKNOWN
:log_level: DEBUG  #开启debug模式，显示更详细的信息，排错的时候使用。1.5版本之前默认是开启的


[root@puppetmaster162 yum.repos.d]# tailf  /var/log/foreman-proxy/proxy.log

失败的情况如下：

备注：Foreman在命令执行后的显示这块做的其实很不好的，如何能够将所有节点执行的情况动态或者显示在界面上就更好了！
