零基础学习Puppet自动化配置管理系列文档
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
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
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
关于如何设置和使用foreman，请关注后续文章....
