在尝试使我的VM看起来像我的在线服务器内部的繁琐过程中……在我看来,Vagrant有一个缺失的部分.现在这个过程似乎或多或少像手动试验和错误.第一次快速设置或者很容易从上游服务器保持同步是不理想的.

不可否认,我可能不知道我正在寻找什么…因此问题.

是否有简化的方法从现有的CentOS 5.10服务器导出设置以进行本地Vagrant配置？ (木偶,厨师,贝壳或其他)

像这样的东西是我想象的……

(连接到在线服务器……)

>根据需要检测repo差异并启用,禁用,添加本地.
>检测包,并同步本地匹配. (从本地安装或删除)
>获取httpd.conf,调整本地(如果需要)和同步.
>获取PHP.ini,调整本地(如果需要)和同步.
>获取MySQL设置,调整本地(如果需要)和同步.
>获取时区和同步.
> [您对其他应该同步的事情的建议在这里欢迎…]

理想情况下,这将在配置期间运行,并且基本上使本地版本与在线版本保持同步.这样就无需手动调整本地设置以保持同步.如果在线(主机或内部)更改了某些内容……它会自动向下传播. (当然,理想情况下,您可以标记设置以根据需要调整行为)

或者,我想如果我可以打包在线服务器而不打包各种用户特定数据,那也可以.然而,从我能说的话来看,这似乎是不可能的……而且它肯定不会非常有效.

警告

在我个人的情况下,我在带有cPanel的CentOS 5.10服务器上. cPanel似乎做了很多服务器端的东西,不一定立即显而易见.一个例子是许多软件包名称以cPanel开头并且看起来是专有的,但同时与我可能想要同步的内容有关. (例如cpanel-PHP53)据我所知,到目前为止,这些都无法轻易同步……因此需要进行解决.另一个例子可能是不同于预期的路径,但我不太确定,因为我对CentOS和cPanel默认安装都不熟悉,以确保任何特性.

到目前为止我做了什么……

在我决定询问是否有更好的方式与Vagrant携手合作之前,我做了一些事情.它并不可怕,但并非真正“精简”或全面.这是细节……

>我学习了如何在两台机器上运行yum repolist以及如何使用cd /etc/yum.repos.d在文件系统中查看repos. ll;,但不是如何使用此信息自动同步回购.
>我编写了一个shell脚本,以使本地的软件包与远程软件包非常接近.然而,虽然它做得很好,但它并不完美,我想知道是否有更好的方法.问题…

>我不确定是否允许删除本地特有的包. (也,
抛出一些错误)
>我还没有解决如何补偿预装了“cpanel”的软件包,它似乎是我真正想要的替代品(PHP,MysqL等),而不是完全从安装列表中删除每个软件包.
>这不能作为Vagrant配置程序运行,因为它需要用户输入的性质.在同一个注意事项中,运行此命令并删除“本地唯一”软件包将删除之前在规定期间运行的yum安装.

3.到7.我写了一个shell脚本来获取一些远程配置文件并将它们移动到本地.它在表面上运作得相当好,但我还没有对结果进行深入测试.我确实运行了日期,看到时区已根据需要同步,并检查了一些文件内容以验证是否成功.

同样,这不能作为Vagrant配置器运行,因为它本质上需要用户输入.此外,没有对文件进行调整,以确保它们可以在本地运行而不会出现问题. (例如http.conf,以确保Apache不会发现某些事情或将MysqL指向正确的数据目录)最后,我确定这些不是我应该移植的唯一文件…这些只是最多的显而易见的.
