#### foreman架构的引入4-安装Foreman1.6.3架构（foreman与puppetmaster分离）
**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](http://kisspuppet.com/2014/01/26/puppet_create_repo/)》，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](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](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
| 角色 | 主机名 | 系统版本 | IP |
|-----|-----|-----|-----|
| foreman | foreman163.kisspuppet.com | rhel6.4-x86_64 | 192.168.20.11/24 |
| puppetmaster | pupptmaster162.kisspuppet.com | rhel6.4-x86_64 | 192.168.20.12/24 |
### 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/2014/10/18/puppet_learning_ext3/)[http://kisspuppet.com/2014/10/20/puppet_learning_ext4/](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: 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](https://192.168.20.11)
记得修改默认密码，否则待会忘了又登录不了了。
### 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**
**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
~~~
