Redhat-7配置yum源

本文详细介绍了在红帽系统中,因未输入注册码导致原YUM源不可用时,如何通过卸载原始YUM源、下载并安装国内YUM源包、配置163网易源,来实现系统软件包的顺利更新和安装。

由于红帽安装时没有输入注册码,故系统自带的yum源时不可用的;

需要进行卸载后安装国内yum源。

1、安装之前要先卸载系统本来的yum源,执行以下命令

[root@localhost ~]# rpm -aq|grep yum|xargs rpm -e --nodeps

注:a、xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令,以避免参数列表过长的问题

       b、--nodeps  强制卸载,不管依赖性

2、查询一下是否完全卸载了

[root@localhost ~]# rpm -qa |grep yum

 

3、下载centos的yum安装包,路径同2,可以直接使用下列链接

卸载原先的python-urlgrabber-3.10-4.el7.noarch.rpm

rpm -e python-urlgrabber-3.10-4.el7.noarch.rpm 

  

  

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-158.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-plugin-fastestmirror-1.1.31-45.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-8.el7.noarch.rpm

4、先把rpm更新为:

报错:rpm >= 0:4.11.3-22 被 yum-3.4.3-158.el7.centos.noarch 需要

rpm -ivh rpm-4.11.3-32.el7.x86_64.rpm --force
忽略冲突强制安装。

5、在当前目录下,安装上面下载的rpm包

rpm -ivh yum-*

 

6、下载centos源:

cd /etc/yum.repos.d/

 wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

gedit CentOS7-Base-163.repo 

把文件的$releasever改为7,如
baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/
baseurl=http://mirrors.163.com/centos/7/updates/$basearch/

 

7、清除原来的源配置

[root@localhost ~]# yum clean all

  

8、安装现在的yum源,这一步也是测试新安装的yum源有没有安装成功

[root@localhost ~]# yum install yum

 如果这条命令能执行成功,就说明新安装的yum源已经正确配置好了。

 

9、更新yum源到本地

[root@localhost ~]# yum list

redhat 7.2 可用的yum, 亲自测试可以使用 ,使用过程: 1.卸载已经存在的yum: rpm -qa | grep yum | xargs rpm -e --nodeps 2.将yum 文件放到server中 3.执行rpm -ivh yum-* 4.创建repo文件: #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 5.测试是否安装成功 yum -y install tree
