Hello !
I am trying to create a local repository , but an error occured.


[root@localhost yum.repos.d]# yum update


Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: mirrors.pidginhost.com
* extras: mirrors.pidginhost.com
* updates: mirrors.pidginhost.com
file:///media/net/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/media/net/repodata/repomd.xml'
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: myrepo. Please verify its path and try again

This is the content of the netinstall.repo :
[myrepo]
name=myrepo
baseurl=file:///media/net/
enabled=1
gpgcheck=0

I don't know what I did wrong

I think I found the answer . I forgot to use createrepo in order to create thex ml-based rpm metadata.
Then , the complete answer would be :
#cd /media
#createrepo .
#cd /etc/yum.repos.d
# vim netinstall.repo
[myrepo]
name=myrepo
baseurl=file:///media
enabled=1
gpgcheck=0
#yum update
PS:[root@localhost yum.repos.d]# mount|grep netinstall
/ISOs/CentOS-5.10-x86_64-netinstall.iso on /media/net type iso9660 (rw,loop=/dev/loop0)

As you can see , /ISOs/CentOS-5.10-x86_64-netinstall.iso is mounted on /media/net ,and I created the repo in /media and the baseurl is ///media .

I hope i didn't forget anything .
I think it is okay .
Sorry , I 've just started learning Linux .
