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(我這里是測試環境,也可以增加puppet端口8140)

復制代碼

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

復制代碼

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

復制代碼

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

2、安裝puppet官方yum源

復制代碼

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)

復制代碼

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:

復制代碼

代碼如下:

yum -y install puppet-server

agent:

復制代碼

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

復制代碼

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

復制代碼

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

復制代碼

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

復制代碼

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)

復制代碼

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'

復制代碼

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

復制代碼

代碼如下:

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

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

復制代碼

代碼如下:

puppet cert --revoke agent1.domain.com

6、master刪除授權

在master端:

復制代碼

代碼如下:

puppet cert --clean agent1.domain.com

在agent端:

復制代碼

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:

復制代碼

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

復制代碼

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

準備工作:

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

復制代碼

代碼如下:

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

一、安裝

復制代碼

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) 或者防火墻和 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 // # 這里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里,不知道什么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 // 進程一直卡在這里

＃安裝完后可以很清楚的看到httpd啟動失敗咱們這里需要手動啟動一下 /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后終端會有顯示

* Foreman is running at https://puppet.domain.com
Initial credentials are <strong>admin / sFuCu73KydURMTbi</strong>
* 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
