在安裝Puppet之前是需要做很多預備工作的，比如網絡地址規範、主機名、certname名、時間等等，也只有這些準備好了，纔不至於在安裝好puppet之後發現問題而後悔莫及。
PS：接下來的整套文檔體系都是以本篇文檔規範方案進行設計和擴充的，同樣也是也是按照準生產的標準進行編寫。
一、網絡地址規範
【HOSTNAME】 【IP】 【certname】 【operatingsystem】
puppetmaster.kisspuppet.com 192.168.100.110/24 puppetmaster_cert.kisspuppet.com RHEL6.4
agent1.kisspuppet.com 192.168.100.111/24 agent1_cert.kisspuppet.com RHEL5.7
agent2.kisspuppet.com 192.168.100.112/24 agent2_cert.kisspuppet.com RHEL5.8
agent3.kisspuppet.com 192.168.100.123/24 agent3_cert.kisspuppet.com RHEL6.41、設置主機名
[root@puppetmaster ~]# vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=puppetmaster.kisspuppet.com
[root@agent1 ~]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=agent1.kisspuppet.com2、設置IP地址
可通過system-config-network命令進行配置好後在進入配置文件進行修改
[root@puppetmaster ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.100.110
NETMASK=255.255.255.0
GATEWAY=192.168.100.110
DNS1=192.168.100.110
IPV6INIT=no
USERCTL=noPS：node1~node3同上
3、關閉NetworkManager服務
NetworkManager服務是RHEL圖形界面管理網卡的服務，由於其開啓會對網絡造成影響，RHEL6默認是開啓的，建議關閉。
[root@puppetmaster ~]# /etc/init.d/NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
[root@puppetmaster ~]# chkconfig NetworkManager off4、關閉防火牆
本實驗主要是爲了測試整個架構的功能，如果要測試防火牆，請另行解決。
[root@puppetmaster ~]# /etc/init.d/iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
[root@puppetmaster ~]# chkconfig iptables off5、關閉selinux
[root@puppetmaster ~]# sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config 6、設置key 爲了操作方便，設置公鑰私鑰，可通過puppetmaster端統一部署
[root@puppetmaster ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
ff:55:8d:31:34:b4:b3:6a:70:3b:aa:09:76:12:5b:8d [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
| .+ |
| . o |
| = |
| o *.|
| . E o . o o|
| + . o o . |
| = . . = . |
| . + . + o |
| o.. . |
+-----------------+
[root@puppetmaster ~]# for i in {1..3}; do ssh-copy-id -i 192.168.100.11$i; done
The authenticity of host '192.168.100.111 (192.168.100.111)' can't be established.
RSA key fingerprint is ae:db:c5:0c:0e:3f:8c:62:ea:a1:26:e2:09:63:18:32.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.100.111' (RSA) to the list of known hosts.

Now try logging into the machine, with "ssh '192.168.100.111'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
...7、設置hosts文件
puppet通信的前提是agent和master必須能夠互相解析主機名。
當然，也可以設置DNS，在第四部分搭建kermit架構的時候會搭建DNS服務，現在先暫時通過hosts文件進行解析，可先設置好puppetmaster後，統一copy到所有節點上
[root@puppetmaster ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.110 puppetmaster.kisspuppet.com puppetmaster
192.168.100.111 agent1.kisspuppet.com agent1
192.168.100.112 agent2.kisspuppet.com agent2
192.168.100.113 agent3.kisspuppet.com agent3
[root@puppetmaster ~]# for i in {1..3}; do scp /etc/hosts 192.168.100.11$i:/etc/; done
hosts 100% 354 0.4KB/s 00:00
hosts 100% 354 0.4KB/s 00:00
hosts 100% 354 0.4KB/s 00:00
[root@agent1 ~]# ping puppetmaster.kisspuppet.com #設置完成之後記得測試下
PING puppetmaster.kisspuppet.com (192.168.100.110) 56(84) bytes of data.

--- puppetmaster.kisspuppet.com ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 1999ms
rtt min/avg/max/mdev = 0.327/0.774/1.000/0.317 msPS：設置完網絡後，可以通過類似Xshell這樣的工具進行登錄，方便操作
二、配置本地光盤yum源
由於我這邊是vmware虛擬機操作，所以光盤是可以直接掛載到某一個目錄裏面，如果是物理機，建議將光盤裏的文件全部copy到指定的一個目錄裏面，然後beaeurl指向它既可。
[root@puppetmaster ~]# mkdir /media/cdrom
[root@puppetmaster ~]# mount /dev/cdrom /media/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@puppetmaster ~]# cp /etc/yum.repos.d/rhel-source.repo /etc/yum.repos.d/rhel-base.repo
[root@puppetmaster ~]# vim /etc/yum.repos.d/rhel-base.repo
[rhel-base]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@puppetmaster ~]# yum clean all
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

[root@puppetmaster ~]# yum install tree lrzsz #測試

...PS：node1~node3同上
說明：RHEL5的report在Server目錄，所以在配置repo文件的時候參數 baseurl=file:///media/cdrom/Server
三、設置NTP服務器
1、配置NTP服務器 設置ntp服務器和本地進行同步，當然如果聯網也可以和外部服務器同步，這裏只需要保證所有服務器時間一致。 原因是因爲，puppetmaster和agent之間時間相差不得超過10分鐘（好像是），而後期配置的mcollecitve服務端和客戶端之間不能相差60秒
[root@puppetmaster ~]# rpm -qa | grep ntp
fontpackages-filesystem-1.41-1.1.el6.noarch
ntpdate-4.2.4p8-3.el6.x86_64 #默認已經安裝
ntp-4.2.4p8-3.el6.x86_64 #默認已經安裝
[root@puppetmaster ~]# cp /etc/ntp.conf{,.bak}
[root@puppetmaster ~]# vim /etc/ntp.conf
driftfile /var/lib/ntp/drift
logfile /var/log/ntp.log
Broadcastdelay 0.008
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
restrict default ignore
restrict 127.0.0.1
restrict -6 ::1
restrict 192.168.100.0 mask 255.255.255.0 notrap nomodify
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10 refid NIST
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
[root@puppetmaster ~]# /etc/init.d/ntpd start
Starting ntpd: [ OK ]
[root@puppetmaster ~]# chkconfig ntpd on
2、節點測試並設置crontab
[root@agent1 ~]# ntpdate puppetmaster.kisspuppet.com
7 Mar 06:08:30 ntpdate[16411]: adjust time server 192.168.100.110 offset 0.049448 sec
[root@agent1 ~]# crontab -l #可通過croutab -e命令設置
*/30 * * * * /usr/sbin/ntpdate puppetmaster.kisspuppet.com >>/root/ntdate.log 2>&1 && /sbin/clock --systohc
[root@agent1 ~]# /etc/init.d/crond reload
Reloading cron daemon configuration: [ OK ]
四、製作本地yum倉庫
本實驗大部分包來自於http://yum.puppetlabs.com，部分包來自於EPEL和Gems官網，rabbitmq官方等，關於如何製作yum倉庫，之前有文章寫道http://kisspuppet.com/2014/01/26/puppet_create_repo/，這裏在簡單操作一下
[root@puppetmaster RHEL6U4]# yum install createrepo #安裝製作軟件包的軟件
[root@puppetmaster RHEL6U4]# createrepo . #將本目錄以及子目錄下所有rpm包生產repodata
Spawning worker 0 with 105 pkgs
Workers Finished
Gathering worker results
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete注：RHEL5的repodata必須在RHEL5環境下運行createrpo命令生成
五、配置FTP服務器
1、安裝並配置FTP服務器
搭建FTP服務器的目的只要是爲自定義yum倉庫做準備
[root@puppetmaster ~]# yum install vsftpd
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

userlist_enable=YES
tcp_wrappers=YES
[root@puppetmaster ~]# /etc/init.d/vsftpd start
Starting vsftpd for vsftpd: [ OK ]
[root@puppetmaster ~]# chkconfig vsftpd on
2、在FTP共享目錄裏製作yum倉庫
將生成好的yum源copy到FTP共享目錄中
[root@puppetmaster ~]# ll /puppet/
total 12
drwxr-xr-x 4 root root 4096 Mar 7 06:21 RHEL5U7
drwxr-xr-x 4 root root 4096 Mar 7 06:21 RHEL5U8

...
六、配置遠程yum倉庫
[root@puppetmaster ~]# vim /etc/yum.repos.d/rhel-puppet.repo
[rhel-puppet]
name=puppetlabs epel gems for rhel
baseurl=ftp://puppetmaster.kisspuppet.com/RHEL6U4 #指向FTP服務器地址
enabled=1
gpgcheck=0
[root@puppetmaster ~]# yum list | grep puppet-server #測試
puppet-server.noarch 2.7.25-1.el6 rhel-puppet
注：node1~node3同上
七、重要軟件版本選型
目前puppet最成熟的版本爲2.7.和3.3版本，兩個版本都可以，本實驗採用2.7版本。
puppet-server 2.7.25-1 來自puppetlabs
puppet 2.7.25-1 來自puppetlabs
facter 1.7.5 來自puppetlabs
puppet-dashboar 1.2.23 來自puppetlabs
ruby 1.8.* 系統自帶
mcollective 2.2.4 來自puppetlabs
activemq 5.5.0 來自puppetlabs
rabbitmq-server 3.1.5 來自rabbitmq官網
kermit-webui 1.2-1 來自kermit官網
...
