yum install zlib 缺失其他包也是一样的办法，我遇到的是：缺失libstdc++.so.6

错误： Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

    1. You have an upgrade for zlib which is missing some
       dependency that another package requires. Yum is trying to
       solve this by installing an older version of zlib of the
       different architecture. If you exclude the bad architecture
       yum will tell you what the root cause is (which package
       requires what). You can try redoing the upgrade with
       --exclude zlib.otherarch ... this should give you an error
       message showing the root cause of the problem.

    2. You have multiple architectures of zlib installed, but
       yum can only see an upgrade for one of those architectures.
       If you don't want/need both architectures anymore then you
       can remove the one with the missing update and everything
       will work.

    3. You have duplicate versions of zlib installed already.
       You can use "yum check" to get yum show these errors.

  ...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).

  保护多库版本：zlib-1.2.7-15.el7.x86_64 != zlib-1.2.7-13.el7.i686
  
  解决：

yum install --setopt=protected_multilib=false zlib
