CentOS6.x 制作ubuntu12.04源

本地的源，可以为你节省大量的时间，尤其在我们这种网络不是太好的环境下。现在很多朋友遇到的无法找到某个包，这种问题基本都是网络造成的。

对于服务器来说，其实只需要64bit就可以，不过你会发现，如果你运行 apt-get update 的话，默认源的设置，还是需要下载i386.

所以未来避免那种错误的提示，你需要把ubuntu 12.04源里所有的东西都下载回来。包括64bit，32bit，源码包。

这个脚本运行环境,需要debmirror. 这是老外写的脚本,我改了一下,加上一个参数:–ignore-release-gpg

设置log

/etc/logrotate.d/ubuntu_mirror

/var/log/ubuntu_mirror.log {
    monthly
    rotate 3
    compress
    delaycompress
    missingok
    notifempty
}

/var/log/ubuntu_mirror.debug {
    weekly
    rotate 3
    compress
    delaycompress
    missingok
    notifempty
}

这个时候，就可以查看到log。目前我正在同步中。

已经用上面脚本，成功把ubuntu 12.04的全部源都下载到本地，总共快120G，并且已经通过cobbler来安装ubuntu，非常顺利完成。
