1. 配置Yum源
RHEL系统安装完成之后，如果没有注册并购买红帽服务是无法连接到官方的Yum源的，也就无法直接使用Yum命令来安装软件包及更新系统。
[root@wuhan2020 /]# hostnamectl
Static hostname: wuhan2020
Icon name: computer-laptop
Chassis: laptop
Machine ID: 601eca308ef84823a9e0a775d944fa23
Boot ID: 2b616f1426814536b6cd7a469718f588
Operating System: Red Hat Enterprise Linux 8.1 (Ootpa)
CPE OS Name: cpe:/o:redhat:enterprise_linux:8.1:GA
Kernel: Linux 4.18.0-147.el8.x86_64
Architecture: x86-64
[root@wuhan2020 /]# yum install thefuck
Updating Subscription Management repositories.

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Error: There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d".
[root@wuhan2020 /]#
[root@wuhan2020 /]# yum update
Updating Subscription Management repositories.

[root@wuhan2020 /]#
但是，我们可以禁用“Subscription Management”，然后配置成我们自己定义的Yum源，也就是Repository库。
可以自定义本地Yum源, 这个很简单，可参考之前的文档。这里我们使用阿里云开源镜像。
[root@wuhan2020 /]# cd /etc/yum.repos.d/ [root@wuhan2020 yum.repos.d]# wget https://mirrors.aliyun.com/repo/Centos-8.repo --2020-02-17 15:17:20-- https://mirrors.aliyun.com/repo/Centos-8.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 47.246.28.228, 47.246.28.229, 47.246.28.224, ...

2. 安装并测试thefuck应用
需要先安装Python, Pip, Python-Devel
RHEL8默认已安装了Python3.6。
[root@wuhan2020 bin]# find /usr/bin/ -name python* /usr/bin/python3.6 /usr/bin/python3.6m /usr/bin/python3 /usr/bin/python-argcomplete-check-easy-install-script /usr/bin/python-argcomplete-tcsh [root@wuhan2020 bin]# ln -s /usr/bin/python3.6 /usr/bin/python [root@wuhan2020 /]# python -V Python 3.6.8
需要手动安装python3-devel
[root@wuhan2020 ~]# yum install python3-devel
安装Pip
[root@wuhan2020 /]# python get-pip.py

配置环境变量
可以添加到bashrc或者/etc/profile文件都行。
[root@wuhan2020 /]# vi /etc/profile
###修改profile文件，在末尾下面一行内容
alias fuck=‘eval $(thefuck $(fc -ln -1)); history -r‘

在安装thefuck时，有遇到如下错误，原因是未安装Python3-devel.
