I use a local, off-line repository for CentOS plus updates for my development network (my setup for many years). By design, the repository has no physical connection to the Internet. Everything seems to be setup correctly and works fine for installs/updates. However I am trying to use the --installroot option for YUM and it is complaining about not finding a mirror. I removed the lines about mirror from my CentOS repo files so I am confused.
My CentOS-Base.repo file contains:
[base] name=CentOS-$releaseserver - Base baseurl=http://myhost.org/yum/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
[updates] name=CentOS-$releaseserver - Updates baseurl=http://myhost.org/yum/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
I have RPMs from the CentOS 5.10 DVDs in a directory indexed by createrepo. I also have a copy of the current updates (as of Monday). I can install and update via this configuration.
My web server has the directory tree: /var/www/html/yum/centos/5 -> /var/www/html/yum/centos/5.10 /var/www/html/yum/centos/5.10/os/i386 /var/www/html/yum/centos/5.10/updates/i386
I am testing some code to make a small, light install. When I run yum with --installroot, it hangs and eventually times out looking for a mirror:
{copy centos-release-5-10.el5.centos.i386.rpm to the current dir} mkdir tmpdir rpm --root=tmpdir -ivh --nodeps centos-release*rpm yum --installroot=tmpdir install basesystem filesystem bash kernel passwd
YUM hangs and eventually responds with:
Could not retrieve mirrorlist http://mirrlist.centos/org/?release=5&arch=i386&repo=os error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution') ...
Anyone have any ideas?
