This article mainly explains how Linux deletes the system's own version of Python, the content is clear, interested friends can learn, I believe it will be helpful after reading.

1. Uninstall python (prevent clean uninstall)

Rpm-qa | grep python | xargs rpm-ev-- allmatches-- nodeps # forcibly delete installed programs and their associations

Whereis python | xargs rm-frv # Delete all remaining files # xargs, allowing you to execute certain other commands on the output

two。 Uninstall yum

Rpm-qa | grep yum | xargs rpm-ev-- allmatches-- nodeps

Rm-rf / etc/yum.repos.d/*

Whereis yum | xargs rm-frv

3. Verify that the deletion is clean

Whereis python # verifies deletion. No result 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 corresponding version of your own system)

Wget http://vault.centos.org/7.5.1804/os/x86_64/Packages/lvm2-python-libs-2.02.177-4.el7.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/libxml2-python-2.9.1-6.el7_2.3.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-libs -2.7.5-68.el7.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-ipaddress-1.0.16-2.el7.noarch.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-backports-1.0-8.el7.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/ Packages/python-backports-ssl_match_hostname-3.5.0.1-1.el7.noarch.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-2.7.5-68.el7.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpmwget http://vault.centos.org/7.5 .1804 / os/x86_64/Packages/python-pycurl-7.19.0-19.el7.x86_64.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-urlgrabber-3.10-8.el7.noarch.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-setuptools-0.9.8-7.el7.noarch.rpmwget http://vault.centos.org/ 7.5.1804/os/x86_64/Packages/python-kitchen-1.1.1-5.el7.noarch.rpmwget http://vault.centos.org/7.5.1804/os/x86_64/Packages/python-chardet-2.2.1-1.el7_1.noarch.rpm

5. Upload and install

I am here or wget directly to a directory after taking the link, and then go directly to the directory to 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

Execute after successful installation

Yum
