Linux 64bit Yum installs 32,,64-bit RPM packages

When installing the Oracle database, many packages are required for both the 32-bit version and the 64-bit version of the RPM package.

Installation via the Yum command is convenient, but only 64-bit RPM packages are installed by default

We can install the 32-bit package by using the following method:

1. Modify the yum.conf configuration file to allow the Yum command to install 32, 64-bit RPM packages simultaneously

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

2. Install the 32-bit package directly via the Yum install

Yum Install unixodbc-devel*i686

Note: CentOS will rename the i386 package to i686, so the Oracle installer will not find the i386 package, as long as the installation is complete, the same, you can directly ignore
