redhat安装yum 提示404 Not Found

  1. 删除自带的yum

    rpm -aq | grep yum | xargs rpm -e --nodeps

  2. 下载yum及其以来的插件

    其他网络源地址

    1.阿里云网络源地址：https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
2.centos网络源地址：http://centos.ustc.edu.cn/centos/7/os/x86_64/Packages/
3.163网络源地址：http://mirrors.163.com/centos/7/os/x86_64/Packages/

    wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm

    需要下载的文件 - 用ctrl + f 搜索对应的安装包 使用wget 命令下载

    - yum
- yum-metadata-parser
- yum-utils
- yum-updateonboot
- yum-plugin-fastestmirror

  3. 安装

    rpm -ivh yum-*

    遇到报错，依赖问题

    [root@localhost /]# rpm -ivh yum-*
警告：yum-2.0.8-1.src.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID : NOKEY
警告：yum-3.4.3-168.el7.centos.noarch.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID : NOKEY
错误：依赖检测失败：
	python-urlgrabber >= 3.10-8 被 yum-3.4.3-168.el7.centos.noarch 需要
	rpm >= 0:4.11.3-22 被 yum-3.4.3-168.el7.centos.noarch 需要

    去网络源站下载需要的安装包

    - python-urlgrabber
- rpm

    更新

    rpm -Uvh python-urlgrabber-3.10-10.el7.noarch.rpm  --nodeps
rpm -Uvh rpm-4.11.3-45.el7.x86_64.rpm  --nodeps

    再次运行安装命令

    rpm -ivh yum-*

  4. 打开repo文件：

    vim /etc/yum.repos.d/CentOS-Base.repo

    输入以下内容：

    # 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.
#

    1. 清理-建立缓存

      yum -y clean all
yum -y makecache

遇到的坑：安装后自动创建了一个repo文件使用这个文件创建缓存时提示404

http://mirrors.aliyun.com/centos/%24releasever/extras/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

需要将文件中的所有==$releaseve== 改为版本号，例如7
