puppet安装和使用

puppet是一种Linux、Unix、windows平台的集中配置管理系统,使用自有的puppet描写叙述语言,可管理配置

文件、用户、cron任务、软件包、系统服务等。puppet把这些系统实体称之为资源,puppet的设计目标

是简化对这些资源的管理以及妥善处理资源间的依赖关系。

puppet採用C/S星状的结构,全部的client和一个或几个server交互。每一个client周期的(默认半个小时)

向server发送请求,获得其最新的配置信息,保证和该配置信息同步。每一个puppetclient每半小时(能够设

置)连接一次server端, 下载最新的配置文件,而且严格依照配置文件来配置server. 配置完毕以后,puppet客

户端能够反馈给server端一个消息. 假设出错,也会给server端反馈一个消息.

puppet通信过程中,client向服务端请求时port是8140,若是server推送到client时通信port是8139,

所以安装和通信过程要注意防火墙的配置!!!能够先关闭.

更新puppet源

rpm -ivh "http://yum.puppetlabs.com/el/5/products/i386/puppetlabs-release-5-1.noarch.rpm"
rpm -ivh "http://yum.puppetlabs.com/el/5/products/x86_64/puppetlabs-release-5-1.noarch.rpm"
rpm -ivh "http://yum.puppetlabs.com/el/6/products/i386/puppetlabs-release-6-1.noarch.rpm"
rpm -ivh "http://yum.puppetlabs.com/el/5/products/x86_64/puppetlabs-release-5-1.noarch.rpm"

puppet服务端安装

# puppet server install ==>> 主机名 : puppet_server IP : 1.1.1.1

yum -y install ruby ruby-lib ruby-rdoc
yum -y install puppet-server
chkconfig puppet on
service puppetmaster start
/etc/init.d/iptables stop > /dev/null 2>&1


puppetclient安装

# puppet client install  ==>> 主机名 : puppet_client IP : 1.1.1.2
echo "1.1.1.1 puppet_server" >> /etc/hosts  (服务端主机名)
yum -y install ruby ruby-lib ruby-rdoc
yum -y install puppet


puppetclient发送证书

#client第一次启动向服务端发送证书,要求签好之后才干通信
puppet agent --no-daemonize --onetime --verbose --debug --server=puppet_server(服务端主机名)

puppet服务端签证书

puppet cert list --all #查看全部client的请求(有+号的代表已经签好证书能够通信,没有加号的代表尚未签好证书)
puppet cert --sign puppet_client(client主机名) #这条命令加client主机名就能签字,自此能够通信


1.以下是一个文件同步的样例

puppet服务端
# vim /etc/puppet/fileserver.conf

# This file consists of arbitrarily named sections/modules
# defining where files are served from and to whom

# Define a section 'files'
# Adapt the allow/deny settings to your needs. Order
# for allow/deny does not matter, allow always takes precedence
# over deny
# [files]
#  path /var/lib/puppet/files
#  allow *.example.com
#  deny *.evil.example.com
#  allow 192.168.0.0/24

# 在以下加一个配置域,名字叫做opencdn,路径是 /etc/puppet
 [opencdn]
  path /etc/puppet
  allow *

# vim /etc/puppet/manifests/site.pp

node default {
        file {
                "/tmp/helloworld.txt" :				==>>推送到client的路径文件
                source=>"puppet:///opencdn/test1/helloworld.txt", ==>> 依据/etc/puppet/fileserver.conf里面配置的opecnd域
               							#终于路径就是 /etc/puppet/test1/helloworld.txt
		recurse=>"true",				==>>能够传送文件夹
                owner=>"root",
                group=>"root",
                mode=>777,
        }
}

# mkdir /etc/puppet/test1/
# cat /etc/puppet/test1/helloworld.txt
到这里为止puppet的服务端已经设置好了

puppetclient

# puppet agent --test --server=puppet_server(服务端主机名)
# cat /tmp/helloworld.txt 就OK了

2.puppet从服务端推送系统命令到client运行

# vim /etc/puppet/manifests/site.pp

node default {
	exec { "/bin/ls > 1.txt": ==>> 这里对于""里面的字符要求非常高,/bin/ls之前都不能有空格,否则就会提示错误
		cwd => "/tmp",	==>> client运行命令的路径
		path=> "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin", ==>> 对于命令的系统路径
	}
}

3.一次推送多个指令

node default {
        exec { "service opencdn restart":
                cwd => "/tmp",
                path=> "/usr/bin:/usr/sbin:/bin:/sbin",
        }
        exec { "ls > 1.txt":
                cwd => "/tmp",
                path=> "/usr/bin:/usr/sbin:/bin:/sbin",
        }
	file {
		"/tmp/helloworld.txt" :
		source=>"puppet:///opencdn/test1/helloworld.txt",
		owner=>"root",
		group=>"root",
		mode=>777,
	}
}
