When you install xxpackage, the NO package bind available appears as follows:

[root@host /] # yum-y install bind

Loaded plugins: fastestmirror, refresh-packagekit, security

Loading mirror speeds from cached hostfile

Setting up Install Process

No package bind available.

I'm used to installing software with yum. I feel like I broke which configuration file I downloaded. So look up the information on the Internet and finally find the reason: there is a configuration file in Centos to store all kinds of software download information, and you will find the software image site automatically when you install it with yum. I hear there are thousands. Enter the following path to see:

Ls / etc/yum.repos.d/

We'll see a file.

CentOS-Base.repo

Enter the command line

Cat CentOS-Base.repo

The result is empty.

Backup / etc/yum.repos.d/CentOS-Base.repo first

Mv / etc/yum.repos.d/CentOS-Base.repo / etc/yum.repos.d/CentOS-Base.repo.backup

Download the corresponding version of repo file and put it in / etc/yum.repos.d/ (please make a backup before operation)

Run yum makecache to generate the cache.
