思路:卸载redhat自带yum,然后下载centos的yum,安装后修改配置文件
1、首先到下载软件包
x86 地址:/6/os/i386/Packages/
x86_64 地址:/6/os/x86_64/Packages/
必要下载的软件包有(以64位系统为例):
a python-iniparse-0.3.1-2.1.el6.noarch.rpm
b yum-3.2.29-40.el6.centos.noarch.rpm
c yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
d yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
下载命令:
wget /6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm wget /6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget /6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget /6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm |
[注] :版本不一定要最新的
2、卸载RedHat自带的yum
rpm -qa | grep yum | xargs rpm -e --nodeps
注:a、xargs是一条和类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
3、安装下载的centos的yum包:
rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
[注] :最后2个需要一起安装,否则会出现依赖性错误
4、到的 centos帮助文档 中下载CentOS6-Base-163.repo文件,存放到/etc/yum.repo.d中
wget
5、编辑CentOS6-Base-163.repo文件,将其中的$releasever更改为centos的版本号
下面是修改好的:
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # #
[base] name=CentOS-6 - Base - 163.com baseurl=/6/os/$basearch/ #mirrorlist= gpgcheck=1 gpgkey=
#released updates [updates] name=CentOS-6 - Updates - 163.com baseurl=/6/updates/$basearch/ #mirrorlist= gpgcheck=1 gpgkey=
#additional packages that may be useful [extras] name=CentOS-6 - Extras - 163.com baseurl=/6/extras/$basearch/ #mirrorlist= gpgcheck=1 gpgkey=
#additional packages that extend functionality of existing packages [centosplus] name=CentOS-6 - Plus - 163.com baseurl=/6/centosplus/$basearch/ #mirrorlist= gpgcheck=1 enabled=0 gpgkey=
#contrib - packages by Centos Users [contrib] name=CentOS-6 - Contrib - 163.com baseurl=/6/contrib/$basearch/ #mirrorlist= gpgcheck=1 enabled=0 gpgkey= |
6、yum clean all 清除原有缓存
7、yum makecache 获取yum列表
出现下面提示,表示yum更改完成:
