前言

安装之前需要卸载自己系统的环境，下面是两个强制删除命令

一、强制删除原有环境

1.删除python

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps ## 强制删除已安装程序及其关联
whereis python |xargs rm -frv ## 删除所有残余文件 ##xargs，允许你对输出执行其他某些命令
whereis python ## 验证删除，返回无结果

2.删除yum

rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps ## 强制删除
whereis yum |xargs rm -frv	## 删除所有相关文件
whereis yum ## 验证删除，返回无结果

二、安装新环境前置准备

在下载的时候需要根据路径名改成自己需要的系统名，与软件名

查看系统内核版本

cat /etc/redhat-release

查看系统位数

getconf LONG_BIT

目标网站（可先在windows上浏览器打开查看我们用到的包所处的路径）

http://vault.centos/

示例：

我的Centos版本是7.6.1810,要用到包在以下网址下面

https://vault.centos/7.6.1810/os/x86_64/Packages/

三、下载依赖命令

在下载依赖包之前可以创建需要先创建以下存放包的路径

mkdir /usr/local/src/python
mkdir /usr/local/src/yum

然后到指定的路径下载指定的依赖包，到指定的路径下执行相应的安装命令

1.内核版本7.6.1810
