chkconfig mysqld on

查看状态

chkconfig --list | grep mysql

mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off

3. 卸载MySQL

查看系统中是否以rpm包安装的MySQL

rpm -qa | grep -i mysql

mysql-5.1.73-8.el6_8.x86_64

mysql-devel-5.1.73-8.el6_8.x86_64

mysql-libs-5.1.73-8.el6_8.x86_64

perl-DBD-MySQL-4.013-3.el6.x86_64

mysql-server-5.1.73-8.el6_8.x86_64

卸载MySQL

rpm -e mysql-5.1.73-8.el6_8.x86_64
rpm -e mysql-devel-5.1.73-8.el6_8.x86_64
rpm -e mysql-libs-5.1.73-8.el6_8.x86_64
rpm -e perl-DBD-MySQL-4.013-3.el6.x86_64
rpm -e mysql-server-5.1.73-8.el6_8.x86_64

删除MySQL服务

chkconfig --list | grep -i mysql
chkconfig --del mysql

删除分散mysql文件夹

find / -name mysql

mysql: /usr/lib/mysql /usr/share/mysql

清空相关mysql的所有目录以及文件
