Redhat 7使用CentOS 7的Yum网络源

本文由LinuxProbe.Com团队成员岳永整理发布,点此查看最新Linux资讯

在学习“第1章 部署虚拟环境安装linux系统—Yum软件仓库”有介绍yum网络源,所以决定尝试一下CentOS的网络源,这样在安装依赖包时就会方便很多,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,另外CentOS公司去年已经被Redhat 收购了,下面是安装步骤。

1、首先查看redhat 7.0系统本身所安装的那些yum 软件包:

[root@linuxprobe ~]# 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、卸载这些软件包;

[root@linuxprobe ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps  [root@linuxprobe ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps  [root@linuxprobe ~]# rpm -e yum-rhn-plugin-2.0.1-4.el7.noarch --nodeps  [root@linuxprobe ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps  [root@linuxprobe ~]# rpm -e yum-langpacks-0.4.2-3.el7.noarch --nodeps  [root@linuxprobe ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps  

3、保证本机电脑能上网;

[root@linuxprobe ~]# ping www.baidu.com  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、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163网络源地址:http://mirrors.163.com/  CentOS网络源地址:http://centos.ustc.edu.cn/centos/  

5、找到自己所需要的版本下载:

[root@Linuxprobe ~]# 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,是安装包更新了,你可以到这个网站http://mirrors.163.com/centos/7/os/x86_64/Packages/复制下载链接,然后再下载下来;    [root@linuxprobe ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm  [root@linuxprobe ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm  [root@linuxprobe ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-34.el7.noarch.rpm  [root@linuxprobe ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-34.el7.noarch.rpm  [root@linuxprobe ~]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm  

6、查看下载完成结果;

[root@linuxprobe ~]# 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、安装软件包:

[root@Linuxprobe ~]# 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;

[root@linuxprobe ~]# 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 网络源已经安装完成;

[root@linuxprobe ~]# yum clean all  

10、测试安装是否正常;

[root@Linuxprobe ~]# 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  ================================================================================================  Package              Arch                     Version                    Repository               Size  ================================================================================================  Installing:  lftp                x86_64                    4.4.8-7.el7                base                     750 k  Transaction Summary  ================================================================================================    Install  1 Package  ………………省略部分安装过程………………  Installed:  lftp.x86_64 0:4.4.8-7.el7  Complete!  

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。
