不同版本的Linux操作系統下軟件源的設置
不同版本的Linux操作系統下軟件源的設置 這四個Linux版本都可以通過設置軟件源而在線安裝或升級軟件。Debian和Ubuntu使用apt，Fedora使用yum而Mandriva使用urpm來執行這些操作。首先得選擇合適的軟件源。

對于Debian，建議使用ustc的源，修改/etc/apt/source.list文件如下：

deb http://debian.ustc.edu.cn/debian/
testing main non-free contrib
deb http://debian.ustc.edu.cn/debian-security/
testing/updates main non-free contrib
deb http://debian.ustc.edu.cn/debian-uo/ sid marillat ustc java misc
#deb http://ftp3.tsinghua.edu.cn/mirror/debian/debian testing main non-free contrib
#deb http://ftp3.tsinghua.edu.cn/mirror/debian/debian-security
testing/updates main non-free contrib
#deb http://ftp3.tsinghua.edu.cn/mirror/debian/debian-unofficial sid marillat ustc java misc

Debian的安裝程序開始只安裝了基本的軟件包，要安裝基本的Gnome系統，可以在命令行下輸入：

apt-get install x-window-system-core gnome-core gdm xscreensaver

對于Ubuntu，建議使用Ubuntu中文站的源，修改/etc/apt/source.list文件如下：

deb http://archive.ubuntu.org.cn/ubuntu dapper main restricted universe multiverse
deb http://archive.ubuntu.org.cn/ubuntu dapper-security main restricted universe multiverse
deb http://archive.ubuntu.org.cn/ubuntu dapper-updates main restricted universe multiverse
deb http://archive.ubuntu.org.cn/ubuntu dapper-backports main universe multiverse restricted
deb http://archive.ubuntu.org.cn/ubuntu-cn dapper main universe multiverse restricted
deb http://archive.ubuntu.org.cn/ubuntu-cn breezy main universe multiverse restricted

對于Fedora，首先修改yum的軟件源，使用速度比較快的國內鏡像。按照以下修改/etc/yum.repos.d目錄的下面fedora-core.repo,fedora-extras.repo和fedora-updates.repo這幾個文件：

#/etc/yum.repos.d/fedora-core.repo
[core]
name=Fedora Core $releasever - $basearch - Base
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/
core/$releasever/$basearch/os/
baseurl=ftp://ftp3.tsinghua.edu.cn/mirror/download.fedora.redhat.com/pub/
fedora/linux/core/$releasever/$basearch/os/
#baseurl=http://mirrors.geekbone.org/fedora/core/$releasever/$basearch/os/
#mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora file:///etc/pki/rpm-gpg/RPM-GPG-KEY
#/etc/yum.repos.d/fedora-extras.repo
