3. Find the installation directory related to the old version of mysql: find /-name mysql

/ var/lib/mysql

4. Use the command rm-rf directory_name to delete all directories found in the previous step:

[root@host1 etc] # rm-rf / var/lib/mysql/

5. Enter the / etc/ directory to check whether the mysql configuration file my.cnf exists, and if so, use the command: rm-f my.cnf to delete it.

[root@host1 etc] # pwd

/ etc

[root@host1 etc] # ls my*

Ls: cannot access my*: No such file or directory

Userdel: mysql home directory (/ var/lib/mysql) not found

[root@host1 etc] # more / etc/passwd | grep mysql
