Question

背景

我正在使用Centos 6.5和Puppet 3.7.3。

我已经安装了模块puppetlabs-mysql v3.1.0

Centos 6.5默认安装MySql 5.1.73。我想要实现的是使用上述模块将该版本通过Puppet升级到5.5.40

初始解决方案

好吧，我找不到合适的解决方案来做到这一点。官方文档仅介绍如何配置puppet清单以安装MySql ，而不考虑版本。这不适合我，因为在运行木偶代理后版本保持不变。

package { "MySQL-client": ensure => installed }

在互联网论坛上找到解决方案＃1

找到here。

package {
    'mysql-client-core-5.5': ensure => present
}

使用该解决方案，我收到以下错误：

Error: Execution of '/usr/bin/yum -d 0 -e 0 -y list mysql-client-core-5.5' 
returned 1: Error: No matching Packages to list

在互联网论坛上找到解决方案＃2

找到here。

实际上它提出了两个解决方案：

package { 'mysql-server' : ensure => '5.5' , }

和

package { 'mysql55w' : ensure => 'present' , }

在这两种情况下，我都会遇到类似的错误，这只是当前已安装的回购

为了解决上述所有问题，我成功地在puppet清单上添加了必要的更改，以安装MySQL 5.5.40所在的repo。

再次重新编制后，我现在遇到了另一个错误：

Error: mysql55w-libs conflicts with mysql-libs-5.1.73-3.el6_5.i686

当然，旧图书馆与新图书馆相冲突。幸运的是，正如here所述，有一种解决方法。我成功地将这些命令添加到我的puppet清单（使用EXEC命令）

yum install mysql.`uname -i` yum-plugin-replace
yum replace mysql --replace-with mysql55w

在所有这些变通办法之后，我的木偶清单执行得很好，但只有在链接每个声明后才能顺序执行它（木偶不承担顺序）。否则，它可能会尝试安装Mysql 5.5之前安装repo或更改库之前。

问题

嗯，问题是，有没有其他方法可以在木偶中更优雅地管理它？

告诉木偶我想安装MySQL是不够的。我实际上不得不告诉Puppet如何做到这一点。

我的Puppet清单看起来像是Puppet应该替换的旧时尚脚本。我不能专注于我想要的东西。我必须指示它如何实现它

即使使用配置管理包，提供商也很头疼！：）

但是，在这种情况下，我们可以通过使用预先存在的模块来管理Yum来利用这项工作：example42/yum

安装模块如下：

puppet module install example42/yum

有了它，它变得更容易管理，你可以安装MySQL 5.5更清洁和明确：

  class { 'yum':
    defaultrepo => false,
    extrarepo   => '' ,
  }

  class { 'yum::repo::mysql_community':
    enabled_version => '5.5',
  }

  package { 'mysql-community-server':
    ensure  => '5.5.42-2.el6',
    require => Class['yum::repo::mysql_community'],
  }

正如您所看到的，唯一使用的顺序是包上的require，以确保在尝试安装Yum repo之前已经设置了它。

在全新的Centos 6.6 Vagrant盒子上为我工作：

# Vagrantfile
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "puppetlabs/centos-6.6-64-puppet"

  config.vm.provision "shell", inline: "puppet module install example42/yum"

  config.vm.provision "puppet" do |puppet|
    puppet.manifests_path = "./"
    puppet.manifest_file  = "default.pp"
  end

end

输出：
