Centos7中卸載mysql5.7操作

首先是 rpm -qa|grep -i mysql

mysql-community-common-5.7.31-1.el7.x86_64
mysql-community-client-5.7.31-1.el7.x86_64
mysql-community-server-5.7.31-1.el7.x86_64
mysql-community-libs-5.7.31-1.el7.x86_64

開始卸載

yum remove mysql-community-libs-5.7.31-1.el7.x86_64
yum remove mysql-community-server-5.7.31-1.el7.x86_64
yum remove mysql-community-common-5.7.31-1.el7.x86_64
yum remove mysql-community-client-5.7.31-1.el7.x86_64

再次運行：rpm -qa|grep -i mysql

 

什么也沒有了

查找mysql的其他相關文件

find / -name mysql

 

刪除文件

rm -rf /etc/selinux/targeted/active/modules/100/mysql/
rm -rf /etc/selinux/targeted/tmp/modules/100/mysql
rm -rf /var/lib/mysql/
rm -rf /usr/share/mysql/

最后，刪除日志

rm -rf /var/log/mysqld.log
rm -rf /var/log/mysql.log

到這里卸載完成，重新安裝。
