# /lib/ld-linux.so.2: bad ELF interpreter解决
bash: /usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
1
是因为64位系统中安装了32位程序 解决方法：
yum install glibc.i686

重新安装以后还有如下类系错误 再继续安装包
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

执行如下命令：
yum install 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 libstdc++ which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libstdc++ 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 libstdc++.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libstdc++ 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 libstdc++ 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：libstdc++-4.8.5-44.el7.i686 != libstdc++-4.8.5-36.el7_6.2.x86_64
