1、简介

Yum（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及CentOS中的Shell前端软件包管理器。基于RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软件包，无须繁琐地一次次下载、安装

2、安装yum

2.1检测是否安装 build-essential 包

sudo apt-get install build-essential 或者 apt-get install build-essential

2.2安装yum

sudo apt-get install yum 或者 apt-get install yum

2.3检测是否安装成功

输入yum指令，看是否有操作提示

3、配置yum源

由于是Ubuntu没有yum源，所以要想使用yum安装软件必须要配置yum安装源。在/etc/yum/repos.d/目录下创建两个文件，fedora-163.repo和fedora-updates-163.repo。分别复制以下配置信息保存即可。

fedora-163.repo配置如下信息

[fedora] name=Fedora 17 - $basearch - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/releases/17/Everything/$basearch/os/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-17&arch=$basearch enabled=1 metadata_expire=7d gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch [fedora-debuginfo] name=Fedora 17 - $basearch - Debug - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/releases/17/Everything/$basearch/debug/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-debug-17&arch=$basearch enabled=0 metadata_expire=7d gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch [fedora-source] name=Fedora 17 - Source - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/releases/17/Everything/source/SRPMS/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-source-17&arch=$basearch enabled=0 metadata_expire=7d gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch

fedora-updates-163.repo配置信息如下

[updates] name=Fedora 17 - $basearch - Updates - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/updates/17/$basearch/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f17&arch=$basearch enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch [updates-debuginfo] name=Fedora 17 - $basearch - Updates - Debug - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/updates/17/$basearch/debug/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-debug-f17&arch=$basearch enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch [updates-source] name=Fedora 17 - Updates Source - 163.com failovermethod=priority baseurl=http://mirrors.163.com/fedora/updates/17/SRPMS/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-source-f17&arch=$basearch enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch
