centos_Error: Protected multilib versions_解决方法

在yum命令后面加入忽略参数：--setopt=protected_multilib=false

you can also use --setopt=protected_multilib=false to remove

this checking, however this is almost never the correct thing to

do as something else is very likely to go wrong (often causing

much more problems).

这里说了，很可能导致more probems。不过么，现实中，可以试试看，尤其是保持一个老系统照旧运行时，这个方法会起作用的。
