[SOLVED] Can't yum install in CentOS

[garry_3peace]

Hello everyone.

I have problem in installing program using yum. When I type for example : yum install vlc

it will produce :

[root@garry ~]yum install vlc
Could not retrieve mirrorlist http://mirrorlist.centos.org/?releas...h=i386&repo=os error was
[Errno 4] IOError: <urlopen error (113, 'No route to host')>
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again.

I am install the CentOS on the VirtualBox. While my computer have proxy, but I have no problem in accessing internet. It can resolve mirrorlist.centos.org. Any idea?

There is an extensive discussion about yum and proxies on this thread. There are also several solutions that will help resolve your problem.

Thank's for the link. But I thought it is not concern to proxy. Since I am using CentOS on Virtualbox. While the one who need proxy is the host computer... Must I set the proxy in the Virtualbox?

I tend to stay clear of virtual machines, so I can't be much help. You could try setting the proxy on the virtual machine and see if that helps.

Hm my fault... At first I thought I don't set the proxy because after I set it, it doesn't effect. But later I just realize, I even don't have a proper network configuration
After configure the network and I am able to download file from internet. I try again to use yum... but this time it said Connection refuse. So this time I set the proxy...

export http_proxy="http://xxxxxx"
export ftp_proxy="http://xxxxxx"

And this time yum is working now I don't understand why yum insist to use proxy while I can download without any problem with wget (without proxy).
Thank you very much for the link daark.child
