Foreman架构的引入6-整合puppetmaster

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

安装好foreman和puppetmaster之后，接下来做的事情就是做整合，目前foreman可以管理puppet的环境、类、类里的变量、报告、facter等信息。接下来会逐一进行介绍。

1、首先要保证智能代理已经代理了puppet和puppet CA

代理puppet以及puppetCA，需要在foreman-proxy中开启。

#配置代理puppet
[root@puppetmaster162 ~]# cat /etc/foreman-proxy/settings.d/puppet.yml 
---
# Puppet management
:enabled: true   #开启
: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
# customrun command details
# Set :customrun_cmd to the full path of the script you want to run, instead of /bin/false
:customrun_cmd: /bin/false
# Set :customrun_args to any args you want to pass to your custom script. The hostname of the
# system to run against will be appended after the custom commands.
:customrun_args: -ay -f -s
# whether to use sudo before the ssh command
:puppetssh_sudo: false
# the command which will be sent to the host
:puppetssh_command: /usr/bin/puppet agent --onetime --no-usecacheonfailure
# With which user should the proxy connect
#:puppetssh_user: root
#:puppetssh_keyfile: /etc/foreman-proxy/id_rsa
# Which user to invoke sudo as to run puppet commands
:puppet_user: root
# URL of the puppet master itself for API requests
:puppet_url: https://puppetmaster162.kisspuppet.com:8140
# SSL certificates used to access the puppet master API
:puppet_ssl_ca: /var/lib/puppet/ssl/certs/ca.pem
:puppet_ssl_cert: /var/lib/puppet/ssl/certs/puppetmaster162.kisspuppet.com.pem
:puppet_ssl_key: /var/lib/puppet/ssl/private_keys/puppetmaster162.kisspuppet.com.pem
# Override use of Puppet's API to list environments, by default it will use only if
# environmentpath is given in puppet.conf, else will look for environments in puppet.conf
#:puppet_use_environment_api: true
#配置代理puppet ca
[root@puppetmaster162 ~]# cat /etc/foreman-proxy/settings.d/puppetca.yml 
---
# PuppetCA management
:enabled: true
:ssldir: /var/lib/puppet/ssl
:puppetdir: /etc/puppet

2、管理puppet环境

2.1、配置puppetmaster环境

puppet从2.6版本开始增加了“目录环境”的功能，更多详情请访问官网https://docs.puppetlabs.com/puppet/latest/reference/environments.html

[root@puppetmaster162 ~]# cat /etc/puppet/puppet.conf 
[master]
    ...
    environmentpath  = /etc/puppet/environments
    basemodulepath   = /etc/puppet/modules:/usr/share/puppet/modules
    environment_timeout = 2  #多长时间刷新一次
[root@puppetmaster162 ~]# ll /etc/puppet/environments/
total 24
drwxr-xr-x 4 root root 4096 Dec  5 16:46 development
drwxr-xr-x 4 root root 4096 Dec  5 16:46 example42
drwxr-xr-x 4 root root 4096 Dec  5 16:39 example_env
drwxr-xr-x 5 root root 4096 Dec  5 17:03 production
drwxr-xr-x 4 root root 4096 Dec  5 16:46 puppetlabs
drwxr-xr-x 7 root root 4096 Dec  5 17:03 temp

注意：从以上配置可以看得出设置了两个环境。

2.2、foreman上导入puppet环境

3、管理puppet类

3.1、配置puppet类

注意以下几点：

puppet.conf中basemodulepath的值所设置的路径为环境目录下所有环境的公共环境，里面的所有模块都会被其他环境搜索到（在没有配置environment.conf的前提下）

环境目录中每个环境目录里面默认应该包含manifests（存放主配置文件site.pp）目录和modules（存放模块）目录，目录结构如下。

  [root@puppetmaster162 environments]# tree production/
  production/
  ├── environment.conf
  ├── manifests
  │   └── site.pp
  ├── modules
  │   ├── jenkins
  │   │   ├── files
  │   │   │   └── jenkins.repo
  │   │   ├── manifests
  │   │   │   ├── init.pp
  │   │   │   ├── install.pp
  │   │   │   ├── service.pp
  │   │   │   └── yum.pp
  │   │   ├── README
  │   │   └── templates
  │   └── motd
  │       ├── files
  │       │   └── motd
  │       ├── manifests
  │       │   └── init.pp
  │       └── templates
  └── system
      └── ssh
          ├── files
          ├── manifests
          │   ├── backup.pp
          │   ├── config.pp
          │   ├── init.pp
          │   ├── install.pp
          │   └── service.pp
          ├── Modulefile
          ├── README
          ├── spec
          │   └── spec_helper.rb
          ├── templates
          │   └── sshd_config.erb
          └── tests
              └── init.pp
  17 directories, 20 files

如果你想在一个环境里包含多个目录，每个目录里面又包含模块，应该添加environment.conf文件

  [root@puppetmaster162 environments]# ll temp/
  total 24
  -rw-r--r--  1 root root   95 Dec  5 17:03 environment.conf  #添加环境搜索配置文件
  drwxr-xr-x 11 root root 4096 Dec  5 17:02 juhailu
  drwxr-xr-x  2 root root 4096 Dec  5 16:48 kisspuppet
  drwxr-xr-x  4 root root 4096 Dec  5 16:56 lin
  drwxr-xr-x  2 root root 4096 Dec  5 16:48 manifests
  drwxr-xr-x  5 root root 4096 Dec  5 16:47 puppetlabs
  [root@puppetmaster162 environments]# ll temp/puppetlabs/
  total 12
  drwxr-xr-x 5 root root 4096 Dec  5 16:46 propuppet-demoapp
  drwxr-xr-x 5 root root 4096 Dec  5 16:46 puppetlabs-demoapp
  drwxr-xr-x 4 root root 4096 Dec  5 16:46 puppet-module-skeleton
  [root@puppetmaster162 environments]# cat temp/environment.conf #添加搜索路径
  modulepath = $basemodulepathmodulesmodulesmodulesmodules

注意：添加搜索路径需要添加$basemodulepath，否则不会去搜索默认公共环境路径。

3.2、Foreman上导入puppet类

4、设置ENC

4.1、通过节点直接管理模块

备注：添加主类就可以了

这样节点和模块就关联上了，相当于在site.pp中添加如下代码

node puppetmaster162.kisspuppet.com{
include ssh
}

4.2、通过组继承模块

备注：如果使用组管理模块，不建议为某个节点单独勾选模块，否则你会发现如果先给节点添加了模块A，然后再给节点对应的组里添加了模块A，那么节点的puppet类哪里就会显示包含的类有两个同名的模块。

5、组与模块之间的管理

5.1、添加配置组

注：foreman从1.5版本开始增加了“配置组”功能，可以将多个模块添加到“配置组”，然后给配置组命名，这样，主机组在勾选模块的时候，只需要勾选配置组即可集成里面所有的模块

6、查看设置是否成功

#可以通过以下方式查看，前提是需要先运行node.rb，可通过"puppet agent"命令或者"node.rb  <certname>" 进行触发。
[root@puppetmaster162 ~]# cat /var/lib/puppet/yaml/foreman/puppetmaster162.kisspuppet.com.yaml 
---
classes:
  ssh: 
parameters:
  puppetmaster: puppetmaster162.kisspuppet.com
  hostgroup: prd
  root_pw: 
  foreman_env: production
  owner_name: Admin User
  owner_email: root@kisspuppet.com

设置以上信息，可以完成ENC的功能，基本可以保障节点和class之间的勾连。可以在节点通过puppet agent命令进行测试。至于如何在foreman上进行推送，关注后续文章。
