注意:本实验是在离线情况下安装的,所以需要在本地创建自己的yum仓库,创建方法可参考《如何根据版本制作属于自己的puppet yum源》,如何你实在是比较懒或者搞不定rpm包之间的依赖关系,那就去我的github上下载吧:https://github.com/kisspuppet/foreman-repo

更多安装细节请参考官网:http://theforeman.org/manuals/1.6/index.html

之前讲的all-in-one方式建议只用于测试使用,如果要用于生产环境,建议将foreman和puppetmaster分离安装,更有利于后期的维护和扩展。还有就是之前你已经部署过puppetmaster了,如何单独部署foreman和puppetmaster通信也是值得考虑的问题。

1、软件包的选型如下:

  • puppet-server 3.6.2
  • puppet 3.6.2
  • facter 2.0.2
  • mcollective 2.2.4
  • rabbitmq-server 3.2.4
  • foreman 1.6.3
  • foreman-proxy 1.6.3

2、系统环境准备

3、安装puppetmaster

3.1、安装puppetmaster,并生成CA和证书

[root@puppetmaster162 ~]# yum install puppet puppet-server facter

[root@puppetmaster162 puppet]# vim /etc/puppet/puppet.conf
[agent]
server = puppetmaster162.kisspuppet.com
pluginsync = false
...
[master]
certname = puppetmaster162.kisspuppet.com
environmentpath  = /etc/puppet/environments
basemodulepath   = /etc/puppet/modules:/usr/share/puppet/modules  
environment_timeout = 10

[root@puppetmaster162 ~]# /etc/init.d/puppetmaster start
Starting puppetmaster:                                     [  OK  ]
[root@puppetmaster162 ~]# puppet cert --list --all
+ "puppetmaster162.kisspuppet.com" (SHA256) 2E:B3:73:4F:CD:EE:0C:64:2C:DF:24:E6:D3:62:F3:1C:AC:A3:28:60:67:1D:0C:8C:C5:CA:68:5B:4B:2F:49:B9 (alt names: "DNS:puppet", "DNS:puppet.kisspuppet.com", "DNS:puppetmaster162.kisspuppet.com")

3.2、测试puppetmaster是否能够正常使用

[root@puppetmaster162 ~]# puppet agent -t
Info: Caching catalog for puppetmaster162.kisspuppet.com
Info: Applying configuration version '1417749612'
Notice: Finished catalog run in 0.04 seconds

注:以上安装方式,puppetmaster工作在Webrick上,性能非常差,需要更换为性能好的web服务器上,如果更换,请参考 http://kisspuppet.com/2014/10/18/puppet_learning_ext3/ http://kisspuppet.com/2014/10/20/puppet_learning_ext4/

4、安装Foreman

4.1、安装puppet客户端并完成认证

#安装
[root@foreman163 ~]# yum install puppet facter
[root@foreman163 ~]# vim /etc/puppet/puppet.conf 
[main]
...
privatekeydir = $ssldir/private_keys { group = service }  
hostprivkey = $privatekeydir/$certname.pem { mode = 640 }

[agent]
server = puppetmaster162.kisspuppet.com
pluginsync = false

#申请认证
[root@foreman163 ~]# puppet  agent -t
Info: Creating a new SSL key for foreman163.kisspuppet.com
Info: Caching certificate for ca
Info: csr_attributes file loading from /etc/puppet/csr_attributes.yaml
Info: Creating a new SSL certificate request for     
Info: Certificate Request fingerprint (SHA256): 35:5D:E5:74:71:E0:FD:D2:67:34:17:92:3D:60:F2:A1:34:26:BA:E5:2D:1F:3A:0E:07:6F:85:38:A8:39:8B:65
Info: Caching certificate for ca
Exiting; no certificate found and waitforcert is disabled

#授权证书
[root@puppetmaster162 ~]# puppet cert --sign foreman163.kisspuppet.com
Notice: Signed certificate request for foreman163.kisspuppet.com
Notice: Removing file Puppet::SSL::CertificateRequest foreman163.kisspuppet.com at '/var/lib/puppet/ssl/ca/requests/foreman163.kisspuppet.com.pem'

#测试
[root@foreman163 ~]# puppet  agent -t
Info: Caching catalog for foreman163.kisspuppet.com
Info: Applying configuration version '1417749612'
Notice: Finished catalog run in 0.05 seconds

4.2、通过foreman-installer安装foreman

foreman默认安装选择的数据库为postgresql,这里选用mysql进行安装。

注意:openssl版本要升级到1.0.1e版本

#先安装包
[root@foreman163 ~]# yum install foreman-installer foreman  mod_passenger mod_ssl ruby193-rubygem-passenger-native mysql mysql-server foreman-mysql2   openssl
...
Updated:
  openssl.x86_64 0:1.0.1e-15.el6                                                   

Replaced:
  ruby193-v8.x86_64 1:3.14.5.10-2.el6                                              

Complete!

#然后通过foreman-installer调用puppet进行配置
[root@foreman163 ~]# foreman-installer --foreman-db-adapter mysql2 --foreman-db-type mysql --no-enable-puppet --no-enable-foreman-proxy --foreman-configure-epel-repo=false
Installing             Done                                               [100%] []
  Success!
  * Foreman is running at https://foreman163.kisspuppet.com
      Initial credentials are admin / 2kWcqJsW6cLDwo7m
  The full log is at /var/log/foreman-installer/foreman-installer.log

注:以上安装完成之后,默认登录密码为随机密码,这跟之前版本有所不同。

安装完成之后,通过火狐或者谷歌浏览器访问看是否安装成功https://192.168.20.11

Foreman安装

Foreman安装

记得修改默认密码,否则待会忘了又登录不了了。
Foreman安装

5、安装Foreman-proxy

注:这里的foreman-proxy主要是代理puppet以及puppetca,所以要安装在puppetmaster上。

5.1、安装foreman-proxy

[root@puppetmaster162 ~]# yum install foreman-installer foreman-proxy tftp-server syslinux

[root@puppetmaster162 yum.repos.d]# foreman-installer --no-enable-foreman --no-enable-foreman-cli --no-enable-foreman-plugin-bootdisk --no-enable-foreman-plugin-setup --no-enable-puppet --enable-foreman-proxy  --foreman-proxy-puppetrun=true  --foreman-proxy-puppetrun-provider=mcollective  --foreman-proxy-puppetca=true   --foreman-proxy-dhcp=false  --foreman-proxy-tftp=false  --foreman-proxy-dns=false --foreman-proxy-register-in-foreman=false  --foreman-configure-epel-repo=false --foreman-configure-scl-repo=false
Installing             Done                                               [100%] []
  Success!
  * Foreman Proxy is running at https://puppetmaster162.kisspuppet.com:8443
  The full log is at /var/log/foreman-installer/foreman-installer.log

#检测8443端口
[root@puppetmaster162 ~]# netstat -nlatp | grep 8443
tcp        0      0 0.0.0.0:8443                0.0.0.0:*                   LISTEN      4635/ruby           

5.2、设置ENC

#从foreman-installer中获取node.rb(貌似不能用,可以通过all-in-one方式安装后获取)
[root@puppetmaster162 ~]# cp /usr/share/foreman-installer/modules/foreman/files/foreman-report_v2.rb  /etc/puppet/node.rb

[root@puppetmaster162 ~]# chown puppet. /etc/puppet/node.rb  #设置属组和属主都为puppet
[root@puppetmaster162 ~]# chmod 550 /etc/puppet/node.rb  #设置执行权限

5.3、设置report

#从foreman-installer中获取foreman.rb
[root@puppetmaster162 ~]# cp /usr/share/foreman-installer/modules/foreman/files/foreman-report_v2.rb  /usr/lib/ruby/site_ruby/1.8/puppet/reports/foreman.rb

5.4、设置连接foreman的信息

#这里跟foreman1.5版本(包括1.5版本)不一样,请注意
[root@puppetmaster162 puppet]# vim /etc/puppet/foreman.yaml 
---
:url: "https://foreman163.kisspuppet.com"
:ssl_ca: "/var/lib/puppet/ssl/certs/ca.pem"
:ssl_cert: "/var/lib/puppet/ssl/certs/puppetmaster162.kisspuppet.com.pem"
:ssl_key: "/var/lib/puppet/ssl/private_keys/puppetmaster162.kisspuppet.com.pem"
:user: ""
:password: ""
:puppetdir: "/var/lib/puppet"
:puppetuser: "puppet"
:facts: true
:timeout: 10
:threads: null
[root@puppetmaster162 ~]# /etc/init.d/foreman-proxy restart
Stopping foreman-proxy:                                    [  OK  ]
Starting foreman-proxy:                                    [  OK  ]

6、注册puppet和puppetca

6.1、在puppetmaster上添加ENC配置和foreman报告

[root@puppetmaster162 ~]# vim /etc/puppet/puppet.conf 
[master]
    ...
    reports        = foreman
    external_nodes = /etc/puppet/node.rb
    node_terminus  = exec
#重启生效
[root@puppetmaster162 ~]# /etc/init.d/puppetmaster restart
Stopping puppetmaster:                                     [  OK  ]
Starting puppetmaster:                                     [  OK  ]

6.2、登录foreman注册foreman-proxy

Foreman安装

6.3、节点测试

[root@foreman163 ~]# puppet  agent -t
Info: Caching catalog for foreman163.kisspuppet.com
Info: Applying configuration version '1417762929'
Notice: Finished catalog run in 0.13 seconds

[root@puppetmaster162 ~]# puppet  agent -t 
Info: Caching catalog for puppetmaster162.kisspuppet.com
Info: Applying configuration version '1417762858'
Notice: Finished catalog run in 0.14 seconds

Foreman安装

注:如果测试报错,请将foreman中的puppet插件的enc_environment选项设置为false,具体如何使用后续讲解
