关于CentOS的出身就不多多说了,拥有RHEL所有功能和性能,甚至更加友好,最重要一点是免费,深受大家的喜爱,CentOS的受欢迎程度并不亚于Ubuntu,之前安装了CentOS7,关于安装的教程,有需要的朋友们可以参考这篇文章: ,下面话不多说了,来一起看看详细的介绍吧。


最近这两天在更新CentOS7系统时,出现了Multilib version problems错误,执行命令:

  # yum update


  ....  ---> Package libcap-ng.i686 0:0.7.5-4.el7 will be installed  ---> Package libstdc++.i686 0:4.8.5-16.el7 will be installed  --> Finished Dependency Resolution  Error: 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 glibc which is missing some    dependency that another package requires. Yum is trying to    solve this by installing an older version of glibc 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 glibc.otherarch ... this should give you an error    message showing the root cause of the problem.      2. You have multiple architectures of glibc 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 glibc 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).
