Fourth, the problems encountered during installation

What should I do if I want to reinstall the wrong installation? Be sure to uninstall clean
1. Use yum to install mysql, use the following command to uninstall
yum remove mysql mysql-server mysql-libs compat-mysql51
rm -rf /var/lib/mysq
rm /etc/my.cnf

2. Use the mysql installed by rpm, use the following command to uninstall
rpm -qa | grep -i mysql

Use the rpm -e command to uninstall the package list in the previous command one by one.

Delete mysql service
chkconfig --list | grep -i mysql
chkconfig --del mysql

Then find out the scattered mysql folders in the OS and delete them.

find / -name mysql
rm -rf these files

Try to try both! ! !
