puppet安装部署，实例JDK和tomcat
puppet 原理和工作流程
puppet 一个为实现数据中心自动化管理而设计的配置管理软件
基于C/S架构
原理：S服务端保存着所有的对客户端服务器的配置代码，puppet里叫清单（manifest)；c客户端下载清单后，根据清单对服务器进行配置
工作流程：客户端调用facter facter探测出主机的一些变量，puppetd 把这些信息通过SSL连接发送到服务器puppetmaster
服务器puppetmaster 检测客户端的主机名，然后找到manifest里面对应主机的配置，对其解析，让客户端执行。客户端每隔30分钟同步一次配置文件。
puppet安装
centos6.5 安装puppet
OS: Centos 6.5 x86_64
Puppet master: master.com (192.168.116.135)
Puppet clients: client1.com (192.168.116.136)
Puppet clients: client2.com (192.168.116.137)
一、先做好安装的准备工作：
1. 在master和client均关闭selinux，iptables：
停止iptables
[root@master ~]# service iptables stop
[root@master ~]# chkconfig ptables off
关闭selinux
[root@master ~]# vim /etc/selinux/config
改成 SELINUX=disabled
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：
[root@master ~]# yum -y install ntp
[root@master ~]# ntpdate pool.ntp.org
[root@master ~]# chkconfig ntpd on
[root@master ~]# chkconfig --list|grep ntp
[root@master ~]# service ntpd start
3. 在master和client端设置主机名和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
[root@master ~]# vim /etc/sysconfig/network
master.com
[root@master ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.116.135 master.com
192.168.116.136 client1.com
192.168.116.137 client2.com
4. 安装puppet官方源(都安装后，克隆改主机名)
[root@master ~]# wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm
[root@master ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm
[root@master ~]# yum update
之上C/S都安装
二、Master端安装配置
1. 安装 puppet-server
[root@master ~]# 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
[root@master ~]# 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 = $vardir/ssl
autosign = true
server = master.com
3. 启动Puppetmaster
[root@master ~]# service puppetmaster start
[root@master ~]# netstat -tunlp | grep :8140
tcp 0 0 0.0.0.0:8140 0.0.0.0:* LISTEN 9148/ruby
4. 开机启动
[root@master ~]# chkconfig --list |grep puppet
[root@master ~]# chkconfig puppetmaster on
[root@master ~]# chkconfig --list |grep puppet
三、客户端安装配置
1. puppet 安装
[root@client1 ~]# yum -y install puppet
2. 为客户端指定puppet服务器,并开启Master的推送功能
编辑 /etc/puppet/puppet.conf 文件，在[agent]段内加入 listen = true，server = master.com
[root@client1 ~]# vim /etc/puppet/puppet.conf
[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in
# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is ‘$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
[root@client1 ~]# vim /etc/puppet/auth.conf
path /run
method save
allow master.com
3. 启动client
[root@client1 ~]# service puppet start
[root@client1 ~]# netstat -tunlp | grep :8139
4. 开机启动
[root@client1 ~]# chkconfig puppet on
[root@client1 ~]# chkconfig --list |grep puppet
测试
[root@client1 ~]#puppet agent --test
[root@master ~]#puppet cert list --all
在服务端安装puppet的dashboard
安装mysql
[root@master ~]# yum install ruby-mysql mysql-server puppet-dashboard
优化mysql设置
[root@master ~]# cp /usr/share/mysql/my-large.cnf /etc/my.cnf
[root@master ~]# vim /etc/my.cnf
[mysqld]
max_allowed_packet = 32M
启动Mysql服务
[root@master ~]# service mysqld start
[root@master ~]# chkconfig mysqld on
[root@master ~]# chkconfig --list |grep mysqld
[root@master ~]# mysqladmin -u root password ‘123456‘
创建一个dashboard数据库
[root@master ~]# mysql -uroot -p123456 <<EOF
> CREATE DATABASE dashboard CHARACTER SET utf8;
> CREATE USER ‘dashboard‘@‘localhost‘ IDENTIFIED BY ‘123456‘;
> GRANT ALL PRIVILEGES ON dashboard.* TO ‘dashboard‘@‘localhost‘;
> FLUSH PRIVILEGES;
> EOF
配置Dashboard
[root@master ~]# vim /usr/share/puppet-dashboard/config/database.yml
production:
database: dashboard
username: dashboard
password: 123456
encoding: utf8
adapter: mysql
修改时区
[root@master ~]# vim /usr/share/puppet-dashboard/config/environment.rb
config.time_zone=‘Beijing‘
初始化数据库
[root@master ~]# cd /usr/share/puppet-dashboard/
[root@master puppet-dashboard]# rake RAILS_ENV=production db:migrate
[root@master ~]# service httpd stop
[root@master ~]# service puppetmaster start
[root@master ~]# service puppet-dashboard start
访问http://master.com:3000
导入报告
cd /usr/share/puppet-dashboard
rake RAILS_ENV=production reports:import
执行报告
cd /usr/share/puppet-dashboard
rake jobs:work RAILS_ENV="production"
例子：
[root@master ~]# mkdir -p /etc/puppet/modules/motd{files,manifests,templates}
[root@master ~]# cd /etc/puppet/modules/motd/files
[root@master ~]# mkdir etc
[root@master ~]# vim motd
---puppet test ----
[root@master ~]# vim /etc/puppet/modules/motd/manifests/init.pp
class motd{ #定义一个类叫motd
package{ ‘setup‘: #定义package资源
ensure => present, #要求setup这个包处于被安装状态
}
file{ ‘/etc/motd‘: #定义file资源

}
[root@master ~]# vim /etc/puppet/manifests/site.pp
$puppetserver = ‘master.com‘ #设置全局变量
node ‘client1.com‘{
include motd
}
[root@client1 ~]#puppet agent --test
