How to completely delete the MySQL 8.0 service under Linux

Before reading this article, it is best to have a certain knowledge of Linux commands, specifically to clear the Mysql installed using yum in the centos7.3 environment

Please shut down the Mysql service before uninstalling

service mysql stop

Use the rpm command to view the installed mysql

rpm -qa|grep mysql

Start uninstalling the Mysql service

Using yum to install requires clearing services first

yum remove mysql mysql-server mysql-libs mysql-server 

Query again

rpm -qa|grep mysql

Use rpm -ev + corresponding file name to delete the corresponding results of Mysql above

rpm -ev mysql-community-common-8.0.17-1.el7.x86_64
rpm -ev mysql80-community-release-el7-3.noarch

Use find / -name mysql to find MySQL-related directory files and delete them accordingly

find / -name mysqlrm -rf + corresponding directory or file name found

Check if there are any missing files (if there are any, use the corresponding deletion command to delete them)

Use ls to list the directory to see if the installation source exists (if yes, delete the corresponding file)

Mysql in this system has been completely cleared

Extension: Both are deletion, what is the difference between rpm -ev and rm -rf?
rpm is a software package manager. It deletes a software package, targeting software; rm -rf deletes a directory or file.
