Note: about how to install two identical software packages in yum install

Today, I just got on the 64-bit Cetnos system and wanted to install mysql. after using yum install mysql, I found that it gave me yum i386 and x86_64 versions, therefore, rpm-qa | grep mysql has two identical mysql databases. if we know the problem is caused by yum, we can start with the yum configuration file; modify/etc/yum. conf file to exclude 32-bit yum installation.

# Vi/etc/yum. conf

[Main]
Cachedir =/var/cache/yum
Keepcache = 0
Debuglevel = 2

......



Exclude = *. I? 86



......

The exclude option supports regular expressions, *. I? 86 can be used to filter out 32-bit packages such as i386 and i686.

If you have installed some 32-bit software packages, you can also run the following command to delete them:

# Yum remove \ *. I \? 86
