Fedora 21 中添加及更新源的命令

原文: Fedora 21 中添加及更新源的命令

fedora的软件源信息文件（*.repo）都是放在 /etc/yum.repos.d 目录下的。可以通过# ls -l /etc/yum.repos.d 查看，因为默认的软件源都是国外的，可能网速不是很快，我们可以自己添加国内软件源和本地软件源。

cd /etc/yum.repos.d

sudo wget http://mirrors.163.com/.help/fedora-163.repo

sudo wget http://mirrors.163.com/.help/fedora-updates-163.repo
sudo wget http://mirrors.sohu.com/help/fedora-sohu.repo

sudo wget http://mirrors.sohu.com/help/fedora-updates-sohu.repo
sudo wget http://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/fedora?codeblock=0

sudo wget http://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/fedora?codeblock=1

刷新缓存

sudo yum makecache

 有插件可以自动选择最快的源

sudo yum install yum-fastestmirror

sudo yum install yum-axelget #是Yum的一个插件，主要用axel来加速下载

以上分别是网易、搜狐、中国科大的镜像源，wget是下载命令，也可以图形化界面下进入镜像站点（例如mirrors.sohu.com点fedora后面的help）按说明下载repo文件放到那个文件夹下。

 

如果yum时出现类似Repository fedora is listed more than once in the configuration的警告, 已163源为例, 重命名红色字

vim /etc/yum.repos.d/fedora-163.repo
