Uninstallation of mysql5.7.37 under CentOS7 [perfect solution]

Execute the following command to view the installed mysql

[[email protected] ~]# rpm -qa|grep -i mysqlmysql-community-client-5.7.37-1.el7.x86_64mysql-community-common-5.7.37-1.el7.x86_64mysql-community-server-5.7.37-1.el7.x86_64mysql-community-libs-5.7.37-1.el7.x86_64mysql-community-libs-compat-5.7.37-1.el7.x86_64

Use the yum -y remove command to remove

#Method 1 Delete all at onceyum -y remove mysql*#Method 2 Delete one by oneyum -y remove mysql-community-client-5.7.37-1.el7.x86_64yum -y remove mysql-community-common-5.7.37-1.el7.x86_64yum -y remove mysql-community-server-5.7.37-1.el7.x86_64yum -y remove mysql-community-libs-5.7.37-1.el7.x86_64yum -y remove mysql-community-libs-compat-5.7.37-1.el7.x86_64

To be safe, delete one by one, maybe when you delete a certain installation package, other installation packages will also be deleted in order to uninstall it cleanly.

After uninstalling the above installation package, check the directory about mysql and delete it all

[[email protected] ~]# find / -name mysql/etc/logrotate.d/mysql/var/lib/mysql/var/lib/mysql/mysql/usr/bin/mysql/usr/lib64/mysql/usr/share/mysql/usr/local/software/mysql

Use the rm -rf command to delete the above directories in turn until the above directories cannot be queried

[[email protected] ~]rm -rf /etc/logrotate.d/mysql[[email protected] ~]rm -rf /var/lib/mysql[[email protected] ~]rm -rf /var/lib/mysql/mysql[[email protected] ~]rm -rf /usr/bin/mysql[[email protected] ~]rm -rf /usr/lib64/mysql[[email protected] ~]rm -rf /usr/share/mysql[[email protected] ~]rm -rf /usr/local/software/mysql

Delete the mysql configuration file

[[email protected] ~]# rm -rf /etc/my.cnf

Delete mysql default password

rm -rf /root/.mysql_historyrm -rf /root/mysql_secret

So far mysql5.7.37 has been uninstalled perfectly
