目前，我的服务器中已经有libxml2.6.16 版本。我们要部署一个新项目，该项目使用 Symfony Framework，并使用更高版本libxml，至少是 2.6.21。此外，我们正在使用 Red Hat Enterprise Linux AS 版本 4。我现在的问题是我应该怎么做，如果需要升级，我该如何升级？
更新
执行此命令后rpm -Uvh libxml2*.rpm
我懂了 ：

答案1
您可以从这里下载 RPM： xml软件 并使用rpm -Uvh libxml*.rpm在同一文件夹中。可用的最旧版本是 2.7.2
这可能会引发依赖噩梦。您可能被迫更新数十个其他程序和/或库。
我建议备份服务器。然后使用apt-get 升级或者apt-get 更新更新整个系统。如果你没有apt-get使用您拥有的任何包管理器。
