[[email protected] ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps
由於redhat 的更新包只對註冊的用戶生效，所以需要自己手動更改成CentOS 的更新包，CentOS幾乎和redhat是一樣的，所以無需擔心軟件包是否可安裝，安裝之後是否有問題，另外CentOS公司去年已經被Redhat 收購了，下面是安裝步驟。
1、首先查看redhat 7.0系統本身所安裝的那些yum 軟件包：
[[email protected] ~]# 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
2、卸載這些軟件包；
[[email protected] ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps [[email protected] ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps [[email protected] ~]# rpm -e yum-rhn-plugin-2.0.1-4.el7.noarch --nodeps [[email protected] ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps [[email protected]
3、保證本機電腦能上網；
[[email protected] ~]# ping www.baidu.co PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data. 64 bytes from 61.135.169.121: icmp_seq=1 ttl=53 time=31.8 ms 64 bytes from 61.135.169.121: icmp_seq=2 ttl=53 time=31.9 ms 64 bytes from 61.135.169.121: icmp_seq=3 ttl=53 time=32.0 ms
4、進入以下網站上面查看軟件包的版本是否升級或者找到自己系統所對應的文件包版本更新；
網易163網絡源地址：http://mirrors.163.com/ CentOS網絡源地址：http://centos.ustc.edu.cn/centos/
5、找到自己所需要的版本下載：
[[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-118.el7.centos.noarch.rpm --2016-01-17 20:43:15-- http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-118.el7.centos.noarch.rpm Resolving mirrors.163.com (mirrors.163.com)... 123.58.173.185, 123.58.173.186 Connecting to mirrors.163.com (mirrors.163.com)|123.58.173.185|:80... connected. HTTP request sent, awaiting response... 404 Not Found 2016-01-17 20:43:15 ERROR 404: Not Found. //如果找不到，是安裝包更新了，你可以到這個網站http://mirrors.163.com/centos/7/os/x86_64/Packages/復制下載鏈接，然後再下載下來； [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-34.el7.noarch.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-34.el7.noarch.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
6、查看下載完成結果；
[[email protected] ~]# ls yum-3.4.3-132.el7.centos.0.1.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm yum-updateonboot-1.1.31-34.el7.noarch.rpm yum-utils-1.1.31-34.el7.noarch.rpm
7、安裝軟件包：
[[email protected] ~]# rpm -ivh yum-* warning: yum-3.4.3-132.el7.centos.0.1.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:yum-metadata-parser-1.1.4-10.el7 ################################# [ 20%] 2:yum-plugin-fastestmirror-1.1.31-3 ################################# [ 40%] 3:yum-3.4.3-132.el7.centos.0.1 ################################# [ 60%] 4:yum-updateonboot-1.1.31-34.el7 ################################# [ 80%] 5:yum-utils-1.1.31-34.el7 ################################# [100%]
8、新建repo 配置文件；
[[email protected] ~]# 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] 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
9、至此YUM 網絡源已經安裝完成；
[[email protected] ~]# yum clean all
10、測試安裝是否正常；
[[email protected] ~]# yum -y install lftp Loaded plugins: fastestmirror, product-id, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package lftp.x86_64 0:4.4.8-7.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved
