[font=宋体]本人是菜鸟，也不是从事IT方面的工作。我这篇帖子，允许不经我同意就可以被转载、修改和再发布，呵呵。[/font]
[font=宋体]我优化yum的知识，主要来源于以下2篇链接文章：[/font]
http://www.linuxsir.org/bbs/showthread.php?t=290570
http://www.linuxsir.org/bbs/show ... 6499&highlight=axel
[font=宋体]感谢wq1977、感谢亚森罗平、以及所有帖子里、帖子外出现的朋友。[/font]
[font=宋体]我这篇的东西只是整理粘贴一下。要深入理解的同学，请详细看上面链接文章。[/font]
[font=宋体]小提示：[/font]
[font=宋体]1、axel插件是wq1977大侠开发的，国货哦。[/font]
http://www.linuxsir.org/bbs/showthread.php?t=290570&highlight=
[font=宋体]2、另有shawn.p.huang大侠开发了一款中文输入法，目前在快速完善升级中，现已率先加入Fedora官方源，详情看这里[/font]
http://www.linuxsir.org/bbs/thread319016.html
[font=宋体]3、Fedora 9 将通过yum-presto插件实现差量下载，也就是说只下载旧包与新包的差异部分。效率几乎提升10倍。[/font]
[font=宋体]以Fedora 8 、axel 1.0b 为例，以root权限操作，开始。[/font]
[font=宋体]＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝[/font]
[font=宋体]一、安装yum-fastestmirror
[table=50%,rgb(242, 240, 199)][tr][td] [color=green][font=宋体]yum install yum-fastestmirror[/font][/td][/tr][/table][/font][/color][font=宋体]
二、安装axel[/font]
[font=宋体] 注：我个人遇到的bug是假如yum（安装axel并启用后）要下载10个文件，第6个就中止了，那么再运行yum命令时，需要10个都重新下载。但这时我会在axelget.conf中把enabled值修改为0临时禁用axel，免得重复下载已完成的包。[/font]
[font=宋体]1、获得axelget.conf
[table=50%,rgb(242, 240, 199)][tr][td] [font=宋体]cd /etc/yum/pluginconf.d/
wget http://wininlinux.googlepages.com/axelget.conf[/font][/td][/tr][/table][/font][font=宋体][/font][font=宋体]2、获得axelget.py
[table=50%,rgb(242, 240, 199)][tr][td] [font=宋体]cd /usr/lib/yum-plugins/
wget http://wininlinux.googlepages.com/axelget.py[/font][/td][/tr][/table][/font][font=宋体][/font][font=宋体]3、获得axel源码和安装。
[table=50%,rgb(242, 240, 199)][tr][td] [font=宋体]cd /usr/local/src
wget http://wilmer.gaast.net/downloads/axel-1.0b.tar.gz
tar zxvf axel-1.0b.tar.gz
cd axel-1.0b
./configure --i18n=1
make
make install[/font][/td][/tr][/table]
[/font][font=宋体][/font][font=宋体]三、优化fedora.repo与fedora-updates.repo文件[/font]
[font=宋体]官方的镜像列表[/font]http://mirrors.fedoraproject.org/publiclist/Fedora/
[font=宋体]优化前请做好备份。
[table=50%,rgb(242, 240, 199)][tr][td] [color=green][font=宋体]tar jcvf MyReposBak.tar.bz2 /etc/yum.repo.d/
chmod 444 MyReposBak.tar.bz2[/font][/td][/tr][/table]
[/font][/color][font=宋体][/font]亚森罗平兄的fedora.repo文件的头一段：

[font=宋体]优化的方法：测试列表http://mirrors.fedoraproject.org/publiclist/Fedora/哪个站点最快。
懒方法是一个个域名ping，把最快的镜像放在上面；
最好的方法是下载一个较大文件对比下载速度。
我优化后的（深圳公网ADSL 2M）平时可达50～130KB/s，快的时候可以达峰值180～210KB/s。根据使用经验，一般以下几个源比较快：[/font]
[font=宋体]mirror.pacific.net.au ----稳定且速度快，但此站点负担了十多个发行版，任务沉重，所以与redhat主站同步较慢。[/font]
[font=宋体]opensource.nchc.org.tw ----台湾省的，时快时慢。[/font]
[font=宋体]ftp.iij.ad.jp ----小日本的，以前好快，现在好像降下来了，不知咋整地。[/font]
[font=宋体]fedora.candishosting.com.cn ----在国内，不知道在北京还是武汉，速度快，但不完整，只用于fedora.repo的[fedora]一段。[/font]
[font=宋体]如果想临时禁用某个源可以在repo文件中前面加“#”，例如这样：（假如运行yum出现包冲突，可能是与redhat主站同步不完全造成的，等几天再更新，或者禁用到只剩下redhat主站）
