如何安装 64 位（x86_64）版本的 MongoDB？
我在 10gen.repo 中指定了 64 位：
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
但是当我跑步时：
yum install mongo-10gen mongo-10gen-server
它设置为安装32位（参见i686）。

我想我知道为什么它想要安装 32 位版本：第一次我制作 10gen.repo 文件时，其中指定了 32 位链接，并安装了 32 位，后来我将其删除了。
可能有些内容已被缓存。有人能帮我解决这个问题吗？

是的，这似乎是一个缓存问题：

清除您的 yum 缓存，然后重试。
yum clean all
