由于redhat 的更新包只对注册的用户生效，所以需要自己手动更改成CentOS 的更新包，CentOS几乎和redhat是一样的，所以无需担心软件包是否可安装，安装之后是否有问题。
| 操作系统：Red Hat Enterprise Linux Server release 7.9 (Maipo) |
1. 首先查看redhat 7.9系统本身所安装的那些yum 软件包
| [root@rhel7 ~]# rpm -qa | grep yum yum-rhn-plugin-2.0.1-10.el7.noarch yum-3.4.3-168.el7.noarch PackageKit-yum-1.1.10-2.el7.x86_64 yum-langpacks-0.4.2-7.el7.noarch yum-utils-1.1.31-54.el7_8.noarch yum-metadata-parser-1.1.4-10.el7.x86_64 |
2. 卸载这些软件包
| [root@rhel7 ~]# rpm -e yum-rhn-plugin-2.0.1-10.el7.noarch --nodeps [root@rhel7 ~]# rpm -e yum-3.4.3-168.el7.noarch --nodeps [root@rhel7 ~]# rpm -e PackageKit-yum-1.1.10-2.el7.x86_64 --nodeps [root@rhel7 ~]# rpm -e yum-langpacks-0.4.2-7.el7.noarch --nodeps 警告：/etc/yum/pluginconf.d/langpacks.conf 已另存为 /etc/yum/pluginconf.d/langpacks.conf.rpmsave [root@rhel7 ~]# rpm -e yum-utils-1.1.31-54.el7_8.noarch --nodeps [root@rhel7 ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps |
3. 保证本机电脑能上网
| [root@rhel7 ~]# ping mirrors.163.com PING mirrors.163.com (106.225.229.135) 56(84) bytes of data. 64 bytes from mirrors.163.com (106.225.229.135): icmp_seq=1 ttl=128 time=4.64 ms 64 bytes from mirrors.163.com (106.225.229.135): icmp_seq=2 ttl=128 time=5.34 ms 64 bytes from mirrors.163.com (106.225.229.135): icmp_seq=3 ttl=128 time=4.72 ms |
4. 进入以下网站上面查看软件包的版本是否升级或者找到自己系统所对应的文件包版本更新
| 网易开源镜像站： 清华大学开源软件镜像站： |
5. 找到自己所需要的版本下载
| [root@rhel7 ~]# wget 7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm [root@rhel7 ~]# wget 7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm [root@rhel7 ~]# wget 7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm [root@rhel7 ~]# wget 7/os/x86_64/Packages/yum-updateonboot-1.1.31-54.el7_8.noarch.rpm [root@rhel7 ~]# wget 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@rhel7 ~]# ll *rpm -rw-r--r-- 1 root root 1298856 10 月 15 2020 yum-3.4.3-168.el7.centos.noarch.rpm -rw-r--r-- 1 root root 28348 7 月 4 2014 yum-metadata-parser-1.1.4-10.el7.x86_64.rpm -rw-r--r-- 1 root root 35216 5 月 14 2020 yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm -rw-r--r-- 1 root root 28024 5 月 14 2020 yum-updateonboot-1.1.31-54.el7_8.noarch.rpm -rw-r--r-- 1 root root 124852 5 月 14 2020 yum-utils-1.1.31-54.el7_8.noarch.rpm |
7. 安装软件包
| [root@rhel7 ~]# rpm -ivh yum-* 警告：yum-3.4.3-168.el7.centos.noarch.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID f4a80eb5: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:yum-metadata-parser-1.1.4-10.el7 ################################# [ 20%] 2:yum-plugin-fastestmirror-1.1.31-5################################# [ 40%] 3:yum-3.4.3-168.el7.centos ################################# [ 60%] 4:yum-updateonboot-1.1.31-54.el7_8 ################################# [ 80%] 5:yum-utils-1.1.31-54.el7_8 ################################# [100%] |
8. 新建repo 配置文件
| [root@rhel7 ~]# vim /etc/yum.repos.d/CentOS7-Base-163.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.

到这里安装完成，以后安装所需包，可以不用本地yum源了，直接使用网络yum源。
