rpm –e –nodeps yum
下载安装依赖
打开浏览器,登录 http://mirrors.163.com/centos/7/os/x86_64/Packages/ ,找四个文件,如下(*****代表版本号,因为版本在不停更新,所以不能精确表明,直接下载最新即可)
1、yum-*****.rpm
2、yum-metadata-parser-*****.rpm
3、yum-plugin-fastestmirror-*****.rpm
4、python-iniparse-*****.rpm
这里我全部以假设下载的版本为1.0.0.0为例。
因文件有相互依赖性,故先安装 python-iniparse-.rpm 文件,再安装 yum-metadata-parser-.rpm,
安装命令如下:
rpm -ivh python-iniparse-1.0.0.0.rpm
rpm -ivh yum-1.0.0.0.rpm
后面的两个依赖需要强制安装,不管依赖性文件加上 “–nodeps –force” 命令
rpm -ivh –nodeps –force yum-plugin-fastestmirror-1.0.0.0.rpm
rpm -ivh –nodeps –force yum-1.0.0.0.rpm
安装过程如果出现警告不用理,如果出现error或者其他异常,请检查下载的版本兼容性。
如果觉得这个官方的太麻烦,直接使用我后面的连接下载文件覆盖原配置文件即可,见3.2
3.1、前往163.com下载配置文件(如果这个操作太麻烦,直接使用3.2方案)
http://mirrors.163.com/.help/CentOS7-Base-163.repo(注意系统的版本,不兼容)
将此配置文件替换/etc/yum.repos.d 同名文件,如果没有同名文件直接上传即可。
3.2、或者直接复制我的配置文件,文件命名为CentOs-Base.repo,然后上传至etc/yum.repos.d,如果这个目录下已经有CentOs-Base.repo以外的其他文件,全部删除掉。
