虚拟机CentOS6.8下
先执行命令查看目录是否存在mysql 文件夹: cd /usr/local 再输入ll
若存在
执行删除命令 rm -rf /usr/local/mysql
再
清空相关mysql的所有目录以及文件
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
rm -rf /usr/my.cnf
删除mysql服务
[root@localhost local]# chkconfig --list | grep -i mysql
[root@localhost local]# chkconfig --del mysql
yum方式安装的mysql
1、yum remove mysql mysql-server mysql-libs compat-mysql51
2、rm -rf /var/lib/mysql
3、rm /etc/my.cnf
查看是否还有mysql软件:
rpm -qa|grep mysql
如果存在的话,继续删除即可。
rpm方式安装的mysql
a)查看系统中是否以rpm包安装的mysql:
[root@localhost opt]# rpm -qa | grep -i mysql
MySQL-server-5.6.17-1.el6.i686
MySQL-client-5.6.17-1.el6.i686
b)卸载mysql
[root@localhost local]# rpm -e MySQL-server-5.6.17-1.el6.i686
[root@localhost local]# rpm -e MySQL-client-5.6.17-1.el6.i686
c)删除mysql服务
[root@localhost local]# chkconfig --list | grep -i mysql
[root@localhost local]# chkconfig --del mysql
d)删除分散mysql文件夹
[root@localhost local]# whereis mysql 或者 find / -name mysql
mysql: /usr/lib/mysql /usr/share/mysql
清空相关mysql的所有目录以及文件
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
rm -rf /usr/my.cnf

# yum remove mysql mysql-server mysql-libs compat-mysql51
[root@localhost usr]
# rm -rf /var/lib/mysql

如果装了mysql-devel(其他一样add command),卸载为:
[root@Tony_ts_tian init.d]# yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51
注(例如):
mysql-5.5.39-1.el6.remi.x86_64
mysql-libs-5.5.39-1.el6.remi.x86_64
compat-mysql51-5.1.54-1.el6.remi.x86_64
mysql-server-5.5.39-1.el6.remi.x86_64

[root@localhost rc.d]
# cd /var/lib/
[root@localhost lib]
# rm -rf mysql/

注:删除MySQL数据库目录(关键) ,否则password不更新(默认安装,如果自定义安装路径和链接路径ln -s ……请删除。)
rm -rf /var/lib/mysql
