  6. CentOS Chroot in 8 easy steps

    1) Download minimal installer iso from mirror: https://www.centos.org/modules/tinycontent/index.php?id=13

    2) Install rpm (rpm.org version)

    3) mount -t iso9660 -o loop,ro CentOS-minimal.iso /mnt/cdrom

    4) mkdir -p /opt/chroot/centos/; rpm —root /opt/chroot/centos/ -i /mnt/cdrom/Packages/*.rpm

    5) cp /etc/resolv.conf /opt/chroot/centos/etc/

    6) Add entry to schroot.conf: (Yes, I assume you have schroot setup already)

    [centos]
    description=CentOS 6.2
    directory=/opt/chroot/centos
    groups=sbuild
    root-groups=wheel
    #personality=linux32
    aliases=stable

    7) schroot -c centos -u root

    8) rpm —initdb; rpm —rebuilddb; pwconv; yum update; yum groupinstall “Development tools”
