So I'll go through proxy
But an error occurs

Same error?

24 
[root@Centos ~]# yum update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http or file.
 Eg. $releasever is not a valid and current release or hasnt been released yet/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/$releasever/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

Can you try to disable fastestmirror?

Thanks very much for guide

problem solved
The problem was DVD!...
Is there a way to password to be entered in the proxy encryption ?

Hey mnnn,

van you explain the problem with the DVD?

As I know there is no security measure for that.

Maybe protect the yum.conf for read by all others.

Hi mnnn,

no there is no other way to protect the file.
But yum is running as root so no one else need to read the file.

protect it with

chmod 640 /etc/yum.conf
chown root:root /etc/yum.conf

So only root and members of the group root are able to read the file.

and yum is working.
If you use

sudo

for running yum so you can also protect it, so that the normal user with sudo rights is not able to read the yum.conf.

I think it is not a security problem.

We are using in our company and no normal user is able to read it.

xabbu
