To use an OpenVZ container

全自動:

查看 Vsersion:

• rinse --version

rinse release 1.9.1

設定檔在:

• /etc/rinse/rinse.conf

[centos-5]
mirror       = http://mirror.bytemark.co.uk/centos/5/os/i386/CentOS/
mirror.amd64 = http://mirror.bytemark.co.uk/centos/5/os/x86_64/CentOS/

換成其他 mirror:

mirror       = http://mirror.centos.org/centos/5/os/i386/CentOS/
mirror.amd64 = http://mirror.centos.org/centos/5/os/x86_64/CentOS/

看有什麼 rpm system 可以安裝:

rinse --list-distributions

        centos-4
        centos-5   <-- 對應 /etc/rinse/centos-5.packages
        centos-6

          --directory    The directory to install the distribution within.
          --distribution The distribution to install.
          --arch         'amd64' | 'i386'
          --print-uris   Only show the RPMs which should be downloaded.

Example:

• rinse --verbose --distribution centos-5 --arch i386 --directory ./centos5

如果安裝中途按過 Ctrl + C 中止, 那會影響以下地方

/var/cache/rinse/centos-5.i386/

• rinse --clean-cache

人手

mkdir centos5

apt-get install rpm2cpio

http://mirrors.kernel.org/centos/5/os/i386/CentOS/

rpm2cpio centos-release-5-8.el5.centos.i386.rpm | cpio -idm

獲得

•     etc/
•     usr/

sed -i 's/$releasever/5/g' ./etc/yum.repos.d/*

setarch i386

yum --installroot=/centos5 groupinstall base
