redhat 7.2 可用的yum源， 亲自测试可以使用 ，使用过程： 1.卸载已经存在的yum: rpm -qa | grep yum | xargs rpm -e --nodeps 2.将yum 文件放到server中 3.执行rpm -ivh yum-* 4.创建repo文件： #CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$7 - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch;=$basearch&repo=os baseurl=http://mirrors.163.com/centos/7/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$7 - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch;=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$7 - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch;=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$7 - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 5.测试是否安装成功 yum -y install tree

1.查看系统本身存在的版本 rpm -qa | grep yum 2.卸载centos7上存在的yum安装源包 rpm -e 源包 --nodeps 3.下载yum源包（http://mirrors.163.com/centos/7/os/x86_64/Packages/） yum-metadata-parser-1.1.4-10.el7.x86_64 PackageKit-yum-1.0.7-6.el7.centos.x86_64 yum-utils-1.1.31-40.el7.noarch 下方两个一起装 yum-plugin-fastestmirror-1.1.31-40.el7.noarch yum-langpacks-0.4.2-7.el7.noarch yum-3.4.3-150.el7.centos.noarch yum-rhn-plugin-2.0.1-6.el7.noarch 4.安装yum源包 rpm -ivh yum* 5.创建配置文件（/etc/yum.repos.d/CentOS-Base.repo） vi /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS-$releasever - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch;=$basearch&repo=os baseurl=http://mirrors.163.com/centos/（系统版本号）7/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch;=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch;=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=$releasever - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 每一个baseurl的centos后都改成自己系统的版本号 6.执行命令 yum clean all yum makecache yum install telnet

最近在使用yum时，需要卸载重装，在http://mirrors.aliyun.com/centos/6/os/x86_64/Packages/下载后，即可使用，目前的版本在阿里云镜像下载不到。特此收藏。 1. yum-3.2.29-73.el6.centos.noarch.rpm 2.yum-metadata-parser-1.1.2-16.el6.x86_6 3.yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm 4.python-urlgrabber-3.9.1-11.el6.noarch.rpm

# 删除redhat自带的yum包 rpm -qa|grep yum|xargs rpm -e --nodeps # 安装yum软件包 # 注意:单个的安装包可能会依赖其它包（例如yum和yum-fastestmirror会相互依赖），所以我们可以把所有这些包放在一起，用一行命令将它们同时安装即可： rpm -ivh python-urlgrabber-3.10-8.el7.noarch.rpm rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-3.4.3-150.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

此安装包包括：yum源和kernel安装包，用户只需下载安装即可
