  1. 检查 rpm 包

    rpm -qa |grep -i mysql
# 运行结果
mysql-community-libs-5.7.37-1.el7.x86_64
mysql57-community-release-el7-10.noarch
mysql-community-server-5.7.37-1.el7.x86_64
mysql-community-common-5.7.37-1.el7.x86_64
mysql-community-libs-compat-5.7.37-1.el7.x86_64
mysql-community-client-5.7.37-1.el7.x86_64

  2. 卸载 rpm

    yum remove mysql-community-libs-5.7.37-1.el7.x86_64
yum remove mysql57-community-release-el7-10.noarch
yum remove mysql-community-server-5.7.37-1.el7.x86_64
yum remove mysql-community-common-5.7.37-1.el7.x86_64
yum remove mysql-community-libs-compat-5.7.37-1.el7.x86_64
yum remove mysql-community-client-5.7.37-1.el7.x86_64

  3. 重新检查应为空

    rpm -qa |grep -i mysql

  4. 查找 mysql 相关目录

    find / -name mysql
# 运行结果
/etc/selinux/targeted/active/modules/100/mysql
/etc/selinux/targeted/tmp/modules/100/mysql
/var/lib/mysql
/var/lib/mysql/mysql
/usr/share/mysql

  5. 逐一删除

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

  6. 删除配置文件

    rm -rf /etc/my.cnf

  7. 删除安装日志,防止重新安装无法记录密码

    rm -rf /var/log/mysqld.log
