在CentOS系統下安裝Puppet和Puppet Foreman的教程

   一、系統環境:

  Centos6.4 x86_64

  192.168.6.171 puppet.domain.com

  192.168.6.173 agent1.domian.com

  二、關閉selinux 和 iptables(我這裡是測試環境,也可以增加puppet端口8140)

  代碼如下:

  setenforce 0

  /etc/init.d/iptables stop && chkconfig iptables off

  三、更改主機名、使用host解析

  代碼如下:

  [root@test ~]# cat /etc/sysconfig/network // # 192.168.6.171

  NETWORKING=yes

  NETWORKING_IPV6=no

  HOSTNAME=puppet.domain.com

  [root@test ~]# cat /etc/hosts

  192.168.6.171 puppet.domain.com

  192.168.6.173 agent1.domain.com

  [root@test ~]cat /etc/sysconfig/network // # 192.168.6.173

  NETWORKING=yes

  NETWORKING_IPV6=no

  HOSTNAME=agent1.domain.com

  [root@test ~]# cat /etc/hosts

  192.168.6.171 puppet.domain.com

  192.168.6.173 agent1.domain.com

  四、安裝yum源

  1、# 下載地址 https://lug.ustc.edu.cn/wiki/mirrors/help/centos

  代碼如下:

  [root@puppet yum.repos.d]# cat CentOS-Base.repo

  # CentOS-Base.repo

  #

  # The mirror system uses the connecting IP address of the client and the

  # update status of each mirror to pick mirrors that are updated to and

  # geographically close to the client. You should use this for CentOS updates

  # unless you are manually picking other mirrors.

  #

  # If the mirrorlist= does not work for you, as a fall back you can try the

  # remarked out baseurl= line instead.

  #

  #

  [base]

  name=CentOS-$releasever - Base - mirrors.ustc.edu.cn

  baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/os/$basearch/

  #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

  gpgcheck=1

  gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

  #released updates

  [updates]

  name=CentOS-$releasever - Updates - mirrors.ustc.edu.cn

  baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/updates/$basearch/

  #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

  gpgcheck=1

  gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

  #additional packages that may be useful

  [extras]

  name=CentOS-$releasever - Extras - mirrors.ustc.edu.cn

  baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/extras/$basearch/

  #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras

  gpgcheck=1

  gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

  #additional packages that extend functionality of existing packages

  [centosplus]

  name=CentOS-$releasever - Plus - mirrors.ustc.edu.cn

  baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/centosplus/$basearch/

  #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus

  gpgcheck=1

  enabled=0

  gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

  #contrib - packages by Centos Users

  [contrib]

  name=CentOS-$releasever - Contrib - mirrors.ustc.edu.cn

  baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/contrib/$basearch/

  #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib

  gpgcheck=1

  enabled=0

  gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

  2、安裝puppet官方yum源

  代碼如下:

  rpm -Uvh http://yum.puppetlabs.com/el/6Server/products/x86_64/puppetlabs-release-6-6.noarch.rpm

  五、安裝ruby環境(master和agent端都要操作)

  代碼如下:

  yum -y install ruby ruby-libs ruby-shadow

  [root@puppet yum.repos.d]# ruby -v //# 檢查ruby版本

  ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

  master:

  代碼如下:

  yum -y install puppet-server

  agent:

  代碼如下:

  yum -y install puppet

  六、puppet配置文件(看到外面很多的文檔又是[main] [agent] [master] 把我都繞暈了 我就直接貼我的配置文件 很簡單要改的東西很少)

  1、master端的配置文件

  代碼如下:

  [root@pupet ~]# cd /etc/puppet/

  [root@pupet puppet]# cat puppet.conf

  [main]

  vardir = /var/lib/puppet // # 用來存放緩存數據、配置、客戶端返回的報告及文件備份

  logdir = /var/log/puppet

  rundir = /var/run/puppet

  ssldir = $vardir/ssl // # 簽發認證文件目錄

  [master]

  reports = foreman,console,log // # 發送報告至console,foreman,log

  certname = puppet.domain.com // # 配置主機名是puppet.domain.com

  pluginsync = true // # 開啟插件同步

  environment = production // # 指定運行環境是生產

  # /etc/init.d/puppetmaster start 啟動puppetmaster

  2、agent端的配置文件

  代碼如下:

  [root@agent ~]# cd /etc/puppet/

  [root@agent puppet]# cat puppet.conf

  [main]

  logdir = /var/log/puppet

  rundir = /var/run/puppet

  ssldir = $vardir/ssl

  pluginsync = true

  [agent]

  classfile = $vardir/classes.txt

  localconfig = $vardir/localconfigs

  #runinterval = 300

  listen = true

  report = true

  server = puppet.domain.com // #指定server端

  # /etc/init.d/puppet start 啟動puppet agent

  七、puppet驗證

  1、客戶端發起驗證

  代碼如下:

  [root@agent1 yum.repos.d]# puppet agent --test --server puppet.domain.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 agent1.domain.com

  Info: Certificate Request fingerprint (SHA256): C0:BB:24:3B:4B:59:F1:63:3D:EA:C1:EB:5B:2D:84:68:23:BA:F3:3D:0A:E6:8C:0E:38:3F:9E:F3:40:24:9A:68

  Info: Caching certificate for ca

  Exiting; no certificate found and waitforcert is disabled

  2、服務端查看

  代碼如下:

  [root@puppet puppet]# puppet cert --list --all

  "agent1.domain.com" (SHA256) C0:BB:24:3B:4B:59:F1:63:3D:EA:C1:EB:5B:2D:84:68:23:BA:F3:3D:0A:E6:8C:0E:38:3F:9E:F3:40:24:9A:68

  + "puppet.domain.com" (SHA256) AF:F9:25:75:0F:3A:C5:E2:B5:71:EE:4E:65:82:7A:C1:3E:20:74:EF:57:2D:2D:1D:E5:47:1D:03:76:A5:5C:07 (alt names: "DNS:puppet", "DNS:puppet.domain.com")

  3、服務端完成驗證(顯示+號代表添加進來了 沒有的話是帶添加的主機)

  代碼如下:

  [root@puppet puppet]# puppet cert sign agent1.domain.com

  Notice: Signed certificate request for agent1.domain.com

  Notice: Removing file Puppet::SSL::CertificateRequest agent1.domain.com at '/var/lib/puppet/ssl/ca/requests/agent1.domain.com.pem'

  代碼如下:

  [root@puppet puppet]# puppet cert --list --all

  + "agent1.domain.com" (SHA256) 70:00:4D:89:53:2B:A4:C4:16:C4:DA:F1:63:59:5A:7A:0C:26:47:3B:74:4D:1C:29:C3:1B:BF:2E:B1:F4:89:D5

  + "puppet.domain.com" (SHA256) AF:F9:25:75:0F:3A:C5:E2:B5:71:EE:4E:65:82:7A:C1:3E:20:74:EF:57:2D:2D:1D:E5:47:1D:03:76:A5:5C:07 (alt names: "DNS:puppet", "DNS:puppet.domain.com")

  4、服務端自動驗證配置

  代碼如下:

  vi /etc/puppet/puppet.conf // # 添加自動驗證配置文件路徑並開啟

  autosign = $confdir/autosign.conf { mode = 664 }

  auto = true

  vi /etc/puppet/autosign.conf // # 指定所有以.domain.com結尾的主機名自動添加驗證

  *.domain.com

  5、master取消授權

  代碼如下:

  puppet cert --revoke agent1.domain.com

  6、master刪除授權

  在master端:

  代碼如下:

  puppet cert --clean agent1.domain.com

  在agent端:

  代碼如下:

  find /var/lib/puppet/ssl/ -iname 'hostname'.pem -exec /bin/rm –rf {}

  八、測試puppet文件推送功能

  master端:

  代碼如下:

  # 定義一個test模塊

  [root@puppet test]# pwd

  /etc/puppet/modules/test

  [root@puppet test]# ls

  files manifests templates

  # 自定資源文件

  [root@puppet test]# cd manifests/

  [root@puppet manifests]# ls

  init.pp

  [root@puppet manifests]# cat init.pp

  class test {

  file { "/tmp/$hostname.txt": content => "hello $hostname.txt"; }

  }

  # 對agent.domain.com節點倒入test模塊

  [root@puppet nodes]# pwd

  /etc/puppet/manifests/nodes

  [root@puppet nodes]# cat agent.domain.com.pp

  node 'agent.domain.com' {

  include test

  }

  # 入口文件導入所有的節點

  [root@puppet manifests]# pwd

  /etc/puppet/manifests

  [root@puppet manifests]# cat site.pp

  import "nodes/*.domain.com.pp"

  # agent 端

  代碼如下:

  [root@agent1 yum.repos.d]# puppet agent --test --server puppet.domain.com

  Notice: Ignoring --listen on onetime run

  Info: Retrieving pluginfacts

  Info: Retrieving plugin

  Info: Caching catalog for agent1.domain.com

  Info: Applying configuration version '1408524165'

  Notice: /Stage[main]/Test/File[/tmp/agent1.txt]/ensure: defined content as '{md5}7509cca57ec6faec2d5dd2c76a68ea0b'

  Notice: Finished catalog run in 0.10 seconds

  # 驗證文件

  [root@agent1 yum.repos.d]# cat /tmp/agent1.txt

  hello agent1.txt

  安裝Puppet foreman

  准備工作:

  1.在安裝foreman之前呢咱們需要安裝epel的源否則在執行yum -y install foreman-installer 很多包是安裝不上的

  代碼如下:

  rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm

  一、安裝

  代碼如下:

  yum -y install http://yum.theforeman.org/releases/1.6/el6/x86_64/foreman-release.rpm // 推薦使用官方的源自動解決依賴問題

  yum -y install foreman-installer // # 開始安裝 如果發現有的包安裝報錯需要仔細檢查是不是源的問題(推薦epel源) 或者 防火牆 和 selinux

  二、運行foreman安裝(以下二選其一即可,推薦非交互安裝方式)

  復制代碼

  代碼如下:

  foreman-installer // # 這裡所有的過程都是自動的 時間有點長,是太長了 好長...我又邪惡了~~

  foreman-installer -i // # 如果需要自定義安裝 可以使用 -i 選擇交互式安裝 詳情請參考官方手冊

  # 貌似每次我安裝都會卡在這裡,不知道什麼原因 我每次都會把它結束掉重新執行foreman-installer 就好了 無解。。

  Installing Debug: Package[foreman-postgresql](provider=yum): [22%] [....................

  5794 ? Ss 0:04 /usr/bin/python /usr/bin/yum -d 0 -e 0 -y install foreman-postgresql // 進程一直卡在這裡

  # 安裝完後可以很清楚的看到httpd啟動失敗 咱們這裡需要手動啟動一下 /etc/init.d/httpd start 安裝兩次都是失敗不知道是不是個例

  Could not start Service[httpd]: Execution of '/sbin/service httpd start' returned 1: Starting httpd: [FAILED]

  /Stage[main]/Apache::Service/Service[httpd]/ensure: change from stopped to running failed: Could not start Service[httpd]: Execution of '/sbin/service httpd start' returned 1: Starting httpd: [FAILED]

  # 啟動foreman-proxy

  /etc/init.d/foreman-proxy start

  三、訪問web頁面

  # 登錄web需要密碼這個密碼在安裝成功後終端會有顯示

  * Foreman is running at https://puppet.domain.com

  Initial credentials are admin / sFuCu73KydURMTbi

  * Foreman Proxy is running at https://puppet.domain.com:8443

  * Puppetmaster is running at port 8140

  The full log is at /var/log/foreman-installer/foreman-installer.log
