Redhat 7.0安裝CentOS 7 的Yum 網絡源

redhat 的更新包隻對注冊的使用者生效，是以我們自己手動更改成CentOS 的更新包，CentOS幾乎和redhat是一樣的，是以無需擔心軟體包是否可安裝，安裝之後是否有問題，另外CentOS公司去年已經被Redhat 收購了，不說費話了，我們還是來操作吧！ 

1、首先檢視redhat 7.0系統本身所安裝的那些yum 軟體包：

[[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、删除這些軟體包；

[[email protected] ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps [r[email protected] ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps [root@localhost ~]# 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 [roo[email protected] ~]# rpm -e yum-langpacks-0.4.2-3.el7.noarch --nodeps [[email protected] ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps

3、本機電腦得能上網；

[[email protected] ~]# ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=48 time=51.3 ms 64 bytes from 8.8.8.8: icmp_seq=2 ttl=48 time=49.5 ms

4、進入以下網站上面檢視軟體包的版本是否更新或者找到自己系統所對應的檔案包版本更新；

網易163網絡源位址：http://mirrors.163.com/ CentOS網絡源位址：http://centos.ustc.edu.cn/centos/

5、找到自己所需要的版本下載下傳：

[[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-118.el7.centos.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-1.1.31-24.el7.noarch.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-24.el7.noarch.rpm [[email protected] ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-24.el7.noarch.rpm

6、檢視下載下傳完成結果；

[[email protected] ~]# ls yum-3.4.3-118.el7.centos.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-plugin-fastestmirror-1.1.31-24.el7.noarch.rpm yum-updateonboot-1.1.31-24.el7.noarch.rpm yum-utils-1.1.31-24.el7.noarch.rpm

7、安裝軟體包：

[[email protected] ~]# rpm -ivh yum-* warning: yum-3.4.3-118.el7.centos.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-1.1.31-2################################# [ 40%]    3:yum-3.4.3-118.el7.centos         ################################# [ 60%]    4:yum-updateonboot-1.1.31-24.el7   ################################# [ 80%]    5:yum-utils-1.1.31-24.el7          ################################# [100%

8、建立repo 配置檔案；

[[email protected] ~]# vim /etc/yum.repos.d/CentOS-Base.repo [base] name=CentOS-$releasever -Base baseurl=http://mirrors.sohu.com/centos/7/os/$basearch/ gpgcheck=1 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #packages used/produced in the build but not released [addons] name=CentOS-$releasever - Addons baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/ gpgcheck=1 #gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ gpgcheck=1 enabled=0

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 zlib zlib-devel openssl openssl-devel pcre pcre-devel 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 No package zlib-devel available. No package pcre-devel available.
