Detailed explanation of the process of deleting the built-in version of Python in Linux

Big pit, don't easily delete the version of Python that comes with the Linux system

1. Uninstall Python (to prevent incomplete uninstallation)

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps #Forced deletion of installed programs and their associations
whereis python|xargs rm -frv #Delete all remaining files #xargs allows you to execute other commands on the output

2. Uninstall yum

rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps
rm -rf /etc/yum.repos.d/*
whereis yum|xargs rm -frv

3. Verify whether the deletion is complete

whereis python #Verify deletion, no results should be returned
whereis yum

4. Install python and yum

Software download address (my system is centos 7.5.1804)

Check the Linux system version: cat /etc/redhat-release

http://vault.centos.org/7.5.1804/os/x86_64/Packages/

The required files are as follows: (Just download the version corresponding to your system)

wget http://vault.centos.org/7.5.1804/os/x86_64/Packages/lvm2-python-libs-2.02.177-4.el7.x86_64.rpm

5. Upload and install

Here I take the link and directly wget to a directory, then enter the directory and execute the command

rpm -Uvh --replacepkgs lvm2-python-libs*.rpm --nodeps --force
 
rpm -Uvh --replacepkgs libxml2-python*.rpm --nodeps --force
 
rpm -Uvh --replacepkgs python*.rpm --nodeps --force
 
rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm --nodeps --force

After successful installation, execute

yum
