我在yum remove msyql上使用yum remove msyql删除了它，它删除了MySQL，但数据文件ibdata和configuration文件（my.cnf）仍然存在。 如何删除所有与MySQL相关的文件，并希望重新开始。
谢谢
默认情况下， yum将使用扩展名.rpmsave重命名configuration文件。 如果你真的想删除与mysql相关的包和configuration文件，试试这个：
# rpm -qa | grep mysql | \ while read p; do \ for f in $(rpm -q --configfiles $p); do \ rm -f $file; done; \ rpm -e $p; \ done
关于datadir，我也build议重新命名而不是删除：
# rm -fr /path/to/datadir/*
您可以使用rpm查看包中包含的所有文件

然后，您可以手动删除文件或写一个脚本来通过并删除它们
