Fedora27配置国内源

虽然目前的linux已经能自动选择最快的源，但是官方提供的镜像列表仍然较少，速度虽有所提升但是整体依然较慢，阿里的源作为国内最快的源却没有被纳入官方提供的源中

国内常使用的源有阿里，中科大，清华，网易源，其中阿里的速度最快，中科大的收录软件最多，其他基本没有什么区别，所以只用这俩个国内源就可以了，没有必要添加太多的源

一 配置阿里源

1 首先备份官方自带的源

 cd /etc/yum.repos.d 

 sudo mv fedora.repo fedora.repo.backup 

 sudo mv fedora-updates.repo fedora-updates.repo.backup  

2 下载阿里源

 sudo wget http://mirrors.aliyun.com/repo/fedora.repo 

 sudo wget http://mirrors.aliyun.com/repo/fedora-updates.repo 

3 更新缓存

 sudo dnf makecache 

到此即可使用阿里源

二 配置科大源

科大的源的配置在官网上有很详细的介绍http://mirrors.ustc.edu.cn/help/

这里就简单搬运一下

将下面的内容复制保存为fedora-ustc.repo并移动到/etc/yum.repos.d/

[fedora-ustc]
name=Fedora $releasever - $basearch - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/releases/$releasever/Everything/$basearch/os/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch
enabled=1
metadata_expire=7d
repo_gpgcheck=0
type=rpm
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

[fedora-ustc-debuginfo]
name=Fedora $releasever - $basearch - Debug - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/releases/$releasever/Everything/$basearch/debug/tree/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-debug-$releasever&arch=$basearch
enabled=0
metadata_expire=7d
repo_gpgcheck=0
type=rpm
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

[fedora-ustc-csource]
name=Fedora $releasever - Source - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/releases/$releasever/Everything/source/tree/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-source-$releasever&arch=$basearch
enabled=0
metadata_expire=7d
repo_gpgcheck=0
type=rpm
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

将下面内容复制保存为fedora-ustc-updates.repo并移动到/etc/yum.repos.d/

[updates-ustc]
name=Fedora $releasever - $basearch - Updates - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/updates/$releasever/$basearch/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=$basearch
enabled=1
repo_gpgcheck=0
type=rpm
gpgcheck=1
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

[updates-ustc-debuginfo]
name=Fedora $releasever - $basearch - Updates - Debug - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/updates/$releasever/Everything/$basearch/debug/tree/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=updates-released-debug-f$releasever&arch=$basearch
enabled=0
repo_gpgcheck=0
type=rpm
gpgcheck=1
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

[updates-ustc-source]
name=Fedora $releasever - Updates Source - ustc
failovermethod=priority
baseurl=https://mirrors.ustc.edu.cn/fedora/updates/$releasever/Everything/source/tree/
#metalink=https://mirrors.fedoraproject.org/metalink?repo=updates-released-source-f$releasever&arch=$basearch
enabled=0
repo_gpgcheck=0
type=rpm
gpgcheck=1
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

最后执行一下
 sudo dnf makecache 
到此即可使用中科大源

三 使用rpmfusion（第三方仓库）

sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

更新一下就可以使用红帽系最大的第三方软件仓库

 sudo dnf update
