零基础学习Puppet自动化配置管理系列文档
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
Foreman安装
Foreman安装
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。
