二、资源介绍

1、实现功能
1.1 管理那些软件包被安装，那些软件包被卸载
1.2 管理软件包是否更新
1.3 要求系统配置yum源（RedHat系统）、zypper源（Suse系统）等等
1.4 有关不同操作系统支持类型请查阅http://docs.puppetlabs.com/references/stable/type.html#package

2、支持参数
2.1 ensure => {present|installed|absent|latest|purged|"version"}, 指定文件的目标状态
=> present|installed, 检查文件是否存在，不存在则新建之
=> absent, 无其他软件依赖，可删除，否则会报错。
=> latest, 检查文件是否为最新版本，否则升级为最新版本
=> purged, 删除该包包括所有依赖的包,有风险慎用
=> "2.7.21-1", 指定某一个版本处于安装状态

2.2 name => package name, 包的名字，默认与title相同可不写

2.3 provider => rpm, 要求通过rpm命令安装包，需要通过source指定安装那些包

三、资源示例
1、示例一
1.1 实现功能
*判断系统为RedHat的情况下安装mysql-server和mysql,系统为SLES的情况下安装mysql和mysql-client，其他系统安装mysql-server和mysql包
*要求安装的包一直处于安装状态
1.2 配置说明

class mysql::install{
    package { "mysql":
               name => $operatingsystem ?
                       {
                       RedHat => ["mysql-server","mysql"],
                       SLES => ["mysql","mysql-client"],
                       default => ["mysql-server","mysql"],
               },
               ensure => installed,
    }
