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

Foreman安装

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

Foreman安装

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 = $basemodulepath:puppetlabs:modules:lin:modules:juhailu:modules:kisspuppet:modules
    

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

Foreman安装

4、设置ENC

4.1、通过节点直接管理模块

Foreman安装

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

Foreman安装

Foreman安装

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

Foreman安装

Foreman安装

#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。
