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

　　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

　　#additional packages that extend functionality of existing packages

　　gpgcheck=1

　　enabled=0

　　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
