系统环境：CentOS6.3
puppet: puppet-2.7.13
facter: facter-1.6.5
ruby: yum源
注：
facter用来获取客户端系统信息(如hostname,ip,OS-Version,fqdn等)
ruby是puppet的开发环境
puppet server: 192.168.7.196
puppet client: 192.168.7.197
(server)为仅服务器端配置
(client)为仅客户器端配置
(server,client)为服务器端与客户端配置
一.配置环境(server,client)：
1.关闭iptables和selinux(server,client)
# service iptables stop # setenforce 0 # vi /etc/sysconfig/selinux --------------- SELINUX=disabled ---------------
2.安装ruby开发环境（centos6.3默认更新源）(server,client)
# yum -y install ruby*
3.计划同步时间：(server,client)
每5分钟同步一次时间
# crontab -e ------------- */5 * * * * /usr/sbin/ntpdate -u asia.pool.ntp.org ------------- # service crond restart # chkconfig crond on
4.修改服务器及客户端HOST及主机名：
(server,client) # vi /etc/hosts ------------------- 192.168.7.196 server.example.com server 192.168.7.197 client.example.com client ------------------- (server) # vi /etc/sysconfig/network ---------------- HOSTNAME=server.example.com ---------------- (client) # vi /etc/sysconfig/network ---------------- HOSTNAME=client.example.com ----------------
二.安装应用软件(server,client)：
(server)：
1.安装facter:
# wget http://downloads.puppetlabs.com/facter/facter-1.6.5.tar.gz # tar zxvf facter-1.6.5.tar.gz # cd facter-1.6.5 # ruby install.rb
2.安装puppet:
# wget http://downloads.puppetlabs.com/puppet/puppet-2.6.13.tar.gz # tar zxvf puppet-2.6.13.tar.gz # cd puppet-2.6.13 # ruby install.rb # cp conf/auth.conf /etc/puppet/ # cp conf/RedHat/fileserver.conf /etc/puppet/ # cp conf/redhat/puppet.conf /etc/puppet/ # mkdir -p /etc/puppet/manifests
设置开机启动脚本：
# cp conf/redhat/server.init /etc/init.d/puppetmaster # chmod +x /etc/init.d/puppetmaster # chkconfig --add puppetmaster # chkconfig puppetmaster on
生成pupput用户:
# puppetmasterd --mkusers
启动puppetmaster服务（端口：8140）:
# service puppetmaster start
(client):
1.安装facter:
# wget http://downloads.puppetlabs.com/facter/facter-1.6.5.tar.gz # tar zxvf facter-1.6.5.tar.gz # cd facter-1.6.5 # ruby install.rb
2.安装puppet:
# wget http://downloads.puppetlabs.com/puppet/puppet-2.6.13.tar.gz # tar zxvf puppet-2.6.13.tar.gz # cd puppet-2.6.13 # ruby install.rb # cp conf/auth.conf /etc/puppet/ # cp conf/namespaceauth.conf /etc/puppet/ # cp conf/redhat/puppet.conf /etc/puppet/
设置开机启动脚本：
# cp conf/redhat/client.init /etc/init.d/puppet # chmod +x /etc/init.d/puppet # chkconfig --add puppet # chkconfig puppet on # vi /etc/puppet/puppet.conf
在[agent]条目下添加以下内容：
------- Listen = true Server = server.example.com -------- # vi /etc/puppet/namespaceauth.conf
修改成以下内容：
--------- [fileserver] allow * [puppetmaster] allow * [puppetrunner] allow * [puppetbucket] allow * [puppetreports] allow * [resource] allow * ---------
生成pupput用户:
# puppetmasterd --mkusers
启动puppet服务（端口：8140）:
# /etc/init.d/puppet start
至此安装完毕，现在需要配置客户端与服务器端的认证连接，从而将服务器端的配置的内容分发到各个客户端，实现集中配置管理。
三.认证并分发：
(client):
客户端发送请求
# puppetd --test --server server.example.com
报错：
--------------------
err: Could not retrieve catalog from remote server: SSL_connect returned=1 errno=0
state=SSLv3 read server certificate B: certificate verify failed
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
--------------------
解决方法：
这可能是换了不同的两台puppetmaster服务器引起的。解决方法，删除现有ssl证书。
# find /var/lib/puppet -type f -print0 |xargs -0r rm
重新发送请求：
# puppetd --test --server server.example.com ------------------- info: Creating a new SSL key for client.example.com warning: peer certificate won't be verified in this SSL session info: Caching certificate for ca warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session info: Creating a new SSL certificate request for client.example.com info: Certificate Request fingerprint (md5): 32:E8:CD:32:BF:62:86:64:B3:98:A4:EB:8A:71:D2:99 warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session warning: peer certificate won't be verified in this SSL session Exiting; no certificate found and waitforcert is disabled -------------------
发送成功。
(server)：
服务器端查看是否有请求证书的客户端服务器
# puppetca --list ------------------ client.example.com (32:E8:CD:32:BF:62:86:64:B3:98:A4:EB:8A:71:D2:99) ------------------
收到客户端认证信息
服务器端对client.example.com签名
# puppetca -s client.example.com
或对所有客户端全部签名
# puppetca -s -a
查看验证签名,注意前面的+号，说明已经签名
# puppetca -a --list --------------------- + client.example.com (19:6F:4C:84:B1:69:16:3C:A1:38:C2:2E:6F:B6:67:12) ---------------------
md5验证服务器端收到的证书是否正确
(server)：
# md5sum /var/lib/puppet/ssl/ca/signed/client.example.com.pem --------------------- 1ebfd47775ec8f3e2ae112d75ccba132 /var/lib/puppet/ssl/ca/signed/client.example.com.pem ---------------------
(client)：
# md5sum /var/lib/puppet/ssl/certs/client.example.com.pem --------------------- 1ebfd47775ec8f3e2ae112d75ccba132 /var/lib/puppet/ssl/certs/client.example.com.pem ---------------------
MD5值相同，说明我们的puppetmaster和客户端的puppet已经成功建立通信
注：出现修改主机名问题引起无法认证，需要重新申请证书，操作可以按照如下两个步骤：
(server)： # rm -rf /var/lib/puppet/ssl/ca/signed/*.pem // "*.pem"为修改过主机名的证书 (client)： # rm -rf /var/lib/puppet/ssl/
配置完毕，开始验证分发效果：
(server)：
修改server端配置文件：
# vi /etc/puppet/manifests/site.pp
-----------------
node default{
file { "/tmp/test":
content=> "this is a test file";
}
}
-----------------重启puppetmaster，更新配置文件信息。
# service puppetmaster restart
(client):
重启puppet（可不用重启）
# service puppet restart
同步文件：
# puppetd --server server.example.com --test
------------------
warning: peer certificate won't be verified in this SSL session
