CentOS7下mysql5.7.37的卸载【完美方案】

执行如下命令查看已经安装的mysql

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

使用yum -y remove命令删除

#方式一 一次性全部删除
yum -y remove mysql*

#方式二 逐个逐个删除
yum -y remove mysql-community-client-5.7.37-1.el7.x86_64
yum -y remove mysql-community-common-5.7.37-1.el7.x86_64
yum -y remove mysql-community-server-5.7.37-1.el7.x86_64
yum -y remove mysql-community-libs-5.7.37-1.el7.x86_64
yum -y remove mysql-community-libs-compat-5.7.37-1.el7.x86_64

保险起见一个一个删除 可能在删除某个安装包时 其他安装包也会跟着删除 为了卸载干净 这样操作也未尝不可

卸载以上安装包之后 查看有关mysql的目录 全部删除

[[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

使用 rm -rf 命令将上面的目录依次删除 直至查询不到上述目录

[[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

删除mysql配置文件

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

删除mysql默认密码

rm -rf /root/.mysql_history
rm -rf /root/mysql_secret

至此mysql5.7.37已完美卸载
