我是靠谱客的博主精明高跟鞋，最近开发中收集的这篇文章主要介绍在CentOS系统下安装Puppet和Puppet Foreman的教程，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

一、系统环境:

Centos6.4 x86_64

192.168.6.171 puppet.domain.com

192.168.6.173 agent1.domian.com

二、关闭selinux 和 iptables(我这里是测试环境,也可以增加puppet端口8140)

复制代码

代码如下:

setenforce 0

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

三、更改主机名、使用host解析

复制代码

代码如下:

[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、安装yum源

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

复制代码

代码如下:

[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

#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

#contrib - packages by Centos Users

gpgcheck=1
enabled=0
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

2、安装puppet官方yum源

复制代码

代码如下:

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

五、安装ruby环境(master和agent端都要操作)

复制代码

代码如下:

yum -y install ruby ruby-libs ruby-shadow

[root@puppet yum.repos.d]# ruby -v //# 检查ruby版本
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

master:

复制代码

代码如下:

yum -y install puppet-server

agent:

复制代码

代码如下:

yum -y install puppet

六、puppet配置文件(看到外面很多的文档又是［main］［agent］［master］把我都绕晕了我就直接贴我的配置文件很简单要改的东西很少)

1、master端的配置文件

复制代码

代码如下:

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

[root@pupet puppet]# cat puppet.conf

[main]

vardir = /var/lib/puppet // # 用来存放缓存数据、配置、客户端返回的报告及文件备份

logdir = /var/log/puppet

rundir = /var/run/puppet

ssldir = $vardir/ssl // # 签发认证文件目录

[master]

reports = foreman,console,log // # 发送报告至console,foreman,log

certname = puppet.domain.com // # 配置主机名是puppet.domain.com

pluginsync = true // # 开启插件同步

environment = production // # 指定运行环境是生产

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

2、agent端的配置文件

复制代码

代码如下:

[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 启动puppet agent

七、puppet验证

1、客户端发起验证

复制代码

代码如下:

[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、服务端查看

复制代码

代码如下:

[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、服务端完成验证(显示+号代表添加进来了没有的话是带添加的主机)

复制代码

代码如下:

[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'

复制代码

代码如下:

[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、服务端自动验证配置

复制代码

代码如下:

vi /etc/puppet/puppet.conf // ＃添加自动验证配置文件路径并开启

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

vi /etc/puppet/autosign.conf // # 指定所有以.domain.com结尾的主机名自动添加验证

*.domain.com

5、master取消授权

复制代码

代码如下:

puppet cert --revoke agent1.domain.com

6、master删除授权

在master端:

复制代码

代码如下:

puppet cert --clean agent1.domain.com

在agent端:

复制代码

代码如下:

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

八、测试puppet文件推送功能

master端:

复制代码

代码如下:

# 定义一个test模块

[root@puppet test]# pwd
/etc/puppet/modules/test
[root@puppet test]# ls
files manifests templates

＃自定资源文件

[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"; }
}

# 对agent.domain.com节点倒入test模块

[root@puppet nodes]# pwd
/etc/puppet/manifests/nodes
[root@puppet nodes]# cat agent.domain.com.pp
node 'agent.domain.com' {
include test
}

# 入口文件导入所有的节点

[root@puppet manifests]# pwd
/etc/puppet/manifests
[root@puppet manifests]# cat site.pp
import "nodes/*.domain.com.pp"

＃ agent 端

复制代码

代码如下:

[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

# 验证文件

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

安装Puppet foreman

准备工作:

1.在安装foreman之前呢咱们需要安装epel的源否则在执行yum -y install foreman-installer 很多包是安装不上的

复制代码

代码如下:

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

一、安装

复制代码

代码如下:

yum -y install http://yum.theforeman.org/releases/1.6/el6/x86_64/foreman-release.rpm // 推荐使用官方的源自动解决依赖问题

yum -y install foreman-installer // # 开始安装如果发现有的包安装报错需要仔细检查是不是源的问题(推荐epel源) 或者防火墙和 selinux

二、运行foreman安装(以下二选其一即可,推荐非交互安装方式)

复制代码

代码如下:

foreman-installer // # 这里所有的过程都是自动的时间有点长，是太长了好长...我又邪恶了～～

foreman-installer -i // # 如果需要自定义安装可以使用 -i 选择交互式安装详情请参考官方手册

＃貌似每次我安装都会卡在这里,不知道什么原因我每次都会把它结束掉重新执行foreman-installer 就好了无解。。

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 // 进程一直卡在这里

＃安装完后可以很清楚的看到httpd启动失败咱们这里需要手动启动一下 /etc/init.d/httpd start 安装两次都是失败不知道是不是个例

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]

# 启动foreman-proxy

/etc/init.d/foreman-proxy start

三、访问web页面

＃登录web需要密码这个密码在安装成功后终端会有显示

* 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
