yum 安装 出错 Error: Protected multilib versions:

yum安装Oracle必需软件：出错 Error: Protected multilib versions:

我安装 libXt出错：

Error: Protected multilib versions: libXt-1.1.4-6.1.el6.i686 != libXt-1.1.3-1.el6.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

原因：多个库共存冲突

解决办法：在执行命令后面加上：--setopt=protected_multilib=false 

再次执行：yum install zlib-1.2.3-29.el6.i686  --setopt=protected_multilib=false 

ok！
