Today, I would like to share with you how Linux gracefully uninstalls MySQL related knowledge points, the content is detailed, the logic is clear, I believe most people still know too much about this knowledge, so share this article for your reference, I hope you can get something after reading this article, let's take a look at it.

Use the following command to check the current installation of mysql to find out whether mysql was previously installed

Rpm-qa | ``grep``-I mysql can see the following figure:

Shows that it was previously installed:

MySQL-client-5.5.25a-1.rhel5

MySQL-server-5.5.25a-1.rhel5

2. Stop the mysql service and delete the previously installed mysql

Delete command: rpm-e-nodeps package name

Rpm-ev MySQL-client-5.5.25a- 1.rhel5``rpm-ev MySQL-server-5.5.25a-1.rhel5 if you are prompted for a dependency package error, try using the following command

Rpm-ev MySQL-client-5.5.25a-1.rhel5-- nodeps if the error is prompted: error:% preun (xxxxxx) scriptlet failed, exit status 1

Try it with the following command:

Rpm-e-noscripts MySQL-client-5.5.25a-1.rhel53, find the directory of the previous version of mysql, and delete files and libraries of the previous version of mysql

Find`` /-name mysql search results are as follows:

Find`` /-name mysql`` / var/lib/ mysql`` / var/lib/mysql/ mysql`` / usr/lib64/mysql delete the corresponding mysql directory

Rm``-rf ``/ var/lib/ mysql``rm``-rf`` / var/lib/ mysql``rm``-rf ``/ usr/lib64/mysql specific steps are shown in figure: find directory and delete

Note: / etc/my.cnf will not be deleted after uninstallation and needs to be deleted manually

Rm``-rf ``/ etc/ my``.cnf4, check again whether mysql is installed on the machine
