redhad 7.0更换yum源

Posted 2023-01-02 qiuyu666

1、  卸载红帽yum源

　　rpm –e $(rpm –qa|grep yum) --node

2、删除所有repo相关文件

         rm –rf /etc/yum.conf

         rm –rf /etc/yum.repos.d/

         rm –rf /var/cache/yum

3、下载centos相关组件

　　网易源：http://mirrors.163.com/centos/6/os/x86_64/Packages/

　　阿里云源：http://mirrors.aliyun.com/centos/6/os/x86_64/Packages/

　　wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm

　　wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

　　wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

　　wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

　　wget http://mirrors.163.com/centos/7/os/x86_64/Packages/ rpm-4.8.0-59.el6.x86_64.rpm

4、安装组件

　　rpm -ivh rpm-4.8.0-59.el6.x86_64.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm python-urlgrabber-3.9.1-11.el6.noarch.rpm yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm 

　　

　　无法安装原因是依赖包冲突：加上--force参数，强制安装

　　

5、下载base和epel仓库

　　wget –O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/CentOS-7.repo

　　wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

　　

　　sed –i ‘s#\\$releasever#7#g’ /etc/yum.repos.d/CentOS-Base.repo

　　sed -i "s;\\$releasever;7;g" /etc/yum.repos.d/CentOS-Base.repo

　　

　　wget –O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo

　　

6、清空缓存和生成缓存

　　yum clean all      #清空 yum 缓存，使其设置生效

　　yum makecache  #加载服务器软件包缓存信息，提高搜索安装软件的速度
