1.首先查看redhat7系统本身所安装的那些yum软件包
root@linux \~\]# rpm -qa \| grep yum yum-utils-1.1.31-24.el7.noarch yum-langpacks-0.4.2-3.el7.noarch yum-metadata-parser-1.1.4-10.el7.x86_64 yum-rhn-plugin-2.0.1-4.el7.noarch PackageKit-yum-0.8.9-11.el7.x86_64 yum-3.4.3-118.el7.noarch (随版本更新名字可能会不一样) 2.删除redhat自带的yum包，卸载上面显示的所有yum包： \[root@localhost \~\]# rpm -qa\|grep yum\|xargs rpm -e --nodeps \[root@localhost \~\]# rpm -qa \|grep yum 或者 rpm -e 包名 --nodeps 3.保证本机电脑能上网，ping一下 4.选择网络源 网易，阿里云都可以 网易：欢迎访问网易开源镜像站 阿里云：阿里巴巴开源镜像站-OPSX镜像站-阿里云开发者社区 5.下载安装包rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-54.el7_8.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm 6.查看下载完成结果 \[root@linux \~\]# ll 7.安装软件包 \[root@linux \~\]# rpm -ivh yum-\* 若安装失败出现以下 warning: package yum-metadata-parser-1.1.4-10.el7.x86_64 was already added, skipping yum-metadata-parser-1.1.4-10.el7.x86_64 error: Failed dependencies: rpm \>= 0:4.11.3-22 is needed by yum-3.4.3-168.el7.centos.noarch 则还需要下载rpm安装包更新一下版本 wget http://mirrors.163.com/centos/7/os/x86_64/Packages/rpm-4.11.3-45.el7.x86_64.rpm 下载之后先安装更新rpm包再安装软件包 8.新建repo配置文件,直接复制粘贴以下内容 \[root@linux \~\]# vim /etc/yum.repos.d/CentOS-Base.repo #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
