在安装Puppet之前是需要做很多预备工作的，比如网络地址规范、主机名、certname名、时间等等，也只有这些准备好了，才不至于在安装好puppet之后发现问题而后悔莫及。说明：接下来的整套文档体系都是以本篇文档规范方案进行设计和扩充的，同样也是也是按照准生产的标准进行编写。
【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 RHEL6.4注：192.168.100.*/24的网关为192.168.100.110 所有服务器的DNS1为192.168.100.110
1、设置主机名
[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.com注：agent2~agent3同上
2、设置IP地址
可通过system-config-network命令进行配置好后在进入配置文件进行修改
[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=no注：node1~node3同上
3、关闭NetworkManager服务
NetworkManager服务是RHEL图形界面管理网卡的服务，由于其开启会对网络造成影响，RHEL6默认是开启的，建议关闭。
[root@puppetmaster ~]# /etc/init.d/NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
[root@puppetmaster ~]# chkconfig NetworkManager off注：node1~node3同上
4、关闭防火墙
本实验主要是为了测试整个架构的功能，如果要测试防火墙，请另行解决。
[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 off注：node1~node3同上
5、关闭selinux
[root@puppetmaster ~]# sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config 注：node1~node3同上
6、设置key为了操作方便，设置公钥私钥，可通过puppetmaster端统一部署
[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 root@puppetmaster.kisspuppet.com
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$i; done
The authenticity of host '192.168.100.111 (192.168.100.111)' can't be established.
RSA key fingerprint is ae:db:c5:0c:0e:3f:8c:62:ea:a1:26:e2:09:63:18:32.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.100.111' (RSA) to the list of known hosts.
root@192.168.100.111's password:
Now try logging into the machine, with "ssh '192.168.100.111'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
...7、设置hosts文件
puppet通信的前提是agent和master必须能够互相解析主机名。当然，也可以设置DNS，在第四部分搭建kermit架构的时候会搭建DNS服务，现在先暂时通过hosts文件进行解析，可先设置好puppetmaster后，统一copy到所有节点上
[root@puppetmaster ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.110 puppetmaster.kisspuppet.com puppetmaster
192.168.100.111 agent1.kisspuppet.com agent1
192.168.100.112 agent2.kisspuppet.com agent2
192.168.100.113 agent3.kisspuppet.com agent3
[root@puppetmaster ~]# for i in {1..3}; do scp /etc/hosts 192.168.100.11$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 #设置完成之后记得测试下

rtt min/avg/max/mdev = 0.327/0.774/1.000/0.317 ms注意：设置完网络后，可以通过类似Xshell这样的工具进行登录，方便操作
二、配置本地光盘yum源
由于我这边是vmware虚拟机操作，所以光盘是可以直接挂载到某一个目录里面，如果是物理机，建议将光盘里的文件全部copy到指定的一个目录里面，然后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

说明：RHEL5的report在Server目录，所以在配置repo文件的时候参数 baseurl=file:///media/cdrom/Server
1、配置NTP服务器设置ntp服务器和本地进行同步，当然如果联网也可以和外部服务器同步，这里只需要保证所有服务器时间一致。原因是因为，puppetmaster和agent之间时间相差不得超过10分钟（好像是），而后期配置的mcollecitve服务端和客户端之间不能相差60秒
[root@puppetmaster ~]# rpm -qa | grep ntp
fontpackages-filesystem-1.41-1.1.el6.noarch
ntpdate-4.2.4p8-3.el6.x86_64 #默认已经安装
ntp-4.2.4p8-3.el6.x86_64 #默认已经安装
[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 192.168.100.0 mask 255.255.255.0 notrap nomodify

includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
[root@puppetmaster ~]# /etc/init.d/ntpd start
Starting ntpd: [ OK ]
[root@puppetmaster ~]# chkconfig ntpd on2、节点测试并设置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 #可通过croutab -e命令设置
*/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 ]本实验大部分包来自于http://yum.puppetlabs.com，部分包来自于EPEL和Gems官网，rabbitmq官方等，关于如何制作yum仓库，之前有文章写道http://kisspuppet.com/2014/01/26/puppet_create_repo/，这里在简单操作一下
[root@puppetmaster RHEL6U4]# yum install createrepo #安装制作软件包的软件
[root@puppetmaster RHEL6U4]# createrepo . #将本目录以及子目录下所有rpm包生产repodata
Spawning worker 0 with 105 pkgs

1、安装并配置FTP服务器
搭建FTP服务器的目的只要是为自定义yum仓库做准备
[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.

[root@puppetmaster ~]# chkconfig vsftpd on2、在FTP共享目录里制作yum仓库
将生成好的yum源copy到FTP共享目录中
[root@puppetmaster ~]# ll /puppet/
