centos_6.5 64位 安装puppet

我们先准备三台centos 6.5 x86_64机器，做好安装前的工作。

OS: Centos 6.5 x86_64

Puppet master: master.com (192.168.37.72)

Puppet clients: client1.com (192.168.37.83)

Puppet clients: client2.com (192.168.37.82)

一、先做好安装的准备工作：

1. 在master和client均关闭selinux，iptables：

   停止iptables

   [[email protected] ~]# service iptables stop
   iptables：清除防火墙规则：                                 [确定]
   iptables：正在卸载模块：                                    [确定]
   [[email protected] ~]# chkconfig --list |grep iptables

   iptables           0:关闭    1:关闭    2:启用    3:启用    4:启用    5:启用    6:关闭

   [[email protected] ~]# chkconfig  ptables off

   关闭selinux

   [[email protected] ~]# vim /etc/selinux/config

   # This file controls the state of SELinux on the system.
   # SELINUX= can take one of these three values:
   #     enforcing - SELinux security policy is enforced.
   #     permissive - SELinux prints warnings instead of enforcing.
   #     disabled - No SELinux policy is loaded.
   SELINUX=enforcing 改成 SELINUX=disabled
   # SELINUXTYPE= can take one of these two values:
   #     targeted - Targeted processes are protected,
   #     mls - Multi Level Security protection.
   SELINUXTYPE=targeted

2. 为了保证能向master主机申请到正确的有效证书，建议master和client设置ntp：

   [[email protected] ~]#  yum -y install ntp

   [[email protected] ~]#  ntpdate pool.ntp.org

   [[email protected] ~]#  chkconfig ntpd on

   [[email protected] ~]# chkconfig --list|grep ntp

   ntpd               0:关闭    1:关闭    2:启用    3:启用    4:启用    5:启用    6:关闭
   ntpdate            0:关闭    1:关闭    2:关闭    3:关闭    4:关闭    5:关闭    6:关闭

   [[email protected] ~]# service ntpd start
   正在启动 ntpd：                                            [确定]

3. 在master和client端设置hosts

   Puppet 要求所有机器有完整的域名，如果没有 DNS 服务器提供域名的话，可以在机器上设置主机名（注意：要先安装
   Puppet之前设置主机名，因为安装 Puppet
   时会把主机名写入证书，客户端和服务端通信需要这个证书）,为了简化安装过程我配置了/etc/hosts。

   [[email protected] ~]# vim /etc/hosts

   127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
   ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
   192.168.37.72 master.com
   192.168.37.83 client1.com
   192.168.37.82 client2.com

4. 安装puppet官方源

   [[email protected] ~]# wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm

   [[email protected] ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm

   [[email protected] ~]# yum update

二、Master端安装配置

1. 安装 puppet-server

   [[email protected] ~]# yum -y install puppet-server

2. 添加自动签发证书

   编辑 /etc/puppet/puppet.conf 文件， 在[main]段内加入 autosign = true，server = master.com

   [[email protected] ~]# vim /etc/puppet/puppet.conf

   [main]
       # The Puppet log directory.
       # The default value is ‘$vardir/log‘.
       logdir = /var/log/puppet

   # Where Puppet PID files are kept.
       # The default value is ‘$vardir/run‘.
       rundir = /var/run/puppet

   # Where SSL certificates are kept.
       # The default value is ‘$confdir/ssl‘.
       ssldir = $vardir/ssl
       autosign = true
       server = master.com

3. 启动Puppetmaster

   [[email protected] ~]# service puppetmaster start

   启动 puppetmaster：                                        [确定]

   [[email protected] ~]#  netstat -tunlp | grep :8140

   tcp        0      0 0.0.0.0:8140                0.0.0.0:*                   LISTEN      9148/ruby

4. 开机启动

   [[email protected] ~]# chkconfig --list |grep puppet
   puppet             0:关闭    1:关闭    2:关闭    3:关闭    4:关闭    5:关闭    6:关闭
   puppetmaster       0:关闭    1:关闭    2:关闭    3:关闭    4:关闭    5:关闭    6:关闭

   [[email protected] ~]# chkconfig puppetmaster on

   [[email protected] ~]# chkconfig --list |grep puppet
   puppet             0:关闭    1:关闭    2:关闭    3:关闭    4:关闭    5:关闭    6:关闭
   puppetmaster       0:关闭    1:关闭    2:启用    3:启用    4:启用    5:启用    6:关闭

三、客户端安装配置

1.  puppet 安装

   [[email protected] ~]# yum -y install puppet

2. 为客户端指定puppet服务器,并开启Master的推送功能

   编辑 /etc/puppet/puppet.conf 文件，在[agent]段内加入 listen = true，server = master.com

   [[email protected] ~]# vim /etc/puppet/puppet.conf

   [agent]
       # The file in which puppetd stores a list of the classes
       # associated with the retrieved configuratiion.  Can be loaded in
       # the separate ``puppet`` executable using the ``--loadclasses``
       # option.
       # The default value is ‘$confdir/classes.txt‘.
       classfile = $vardir/classes.txt

   # Where puppetd caches the local configuration.  An
       # extension indicating the cache format is added automatically.
       # The default value is ‘$confdir/localconfig‘.
       localconfig = $vardir/localconfig
       listen = true
       server = master.com

   编辑 /etc/puppet/auth.conf 文件， 在 auth / 最下面加入以下语句

   [[email protected] ~]# vim /etc/puppet/auth.conf

   path /run
   method save
   allow master.com

3. 启动client

   [[email protected] ~]# service puppet start
   Starting puppet agent:                                     [确定]

   [[email protected] ~]#  netstat -tunlp | grep :8139
   tcp        0      0 0.0.0.0:8139                0.0.0.0:*                   LISTEN      15038/ruby

4. 开机启动

   [[email protected] ~]# chkconfig puppet on

   [[email protected] ~]# chkconfig --list |grep puppet

   puppet             0:关闭    1:关闭    2:启用    3:启用    4:启用    5:启用    6:关闭
