Linux 64bit yum同时安装32,,64位rpm包

在安装Oracle数据库的时候,很多包是同时需要32位版本和64位版本的rpm包的

通过yum命令进行安装很方便,但是默认情况下只会安装64位的rpm包

我们可以通过下面的方法进行安装32位的包:

1,修改yum.conf配置文件,使yum命令同时安装32,64位的rpm包

echo "multilib_policy=all" >>/etc/yum.conf

2.通过yum install直接安装32位的包

yum install unixODBC-devel*i686


注意:CentOS将i386的包都重命名成了i686,所以会导致Oracle安装程序找不到i386的包,只要安装完整了,都是一样的,可以直接忽略
