linux卸载mysql数据库的步骤：
第一步：查看系统中是否以rpm包安装的mysql
[plain] view plaincopyprint?
[root@linux ~]# rpm -qa | grep -i mysql
MySQL-server-5.1.49-1.glibc23
MySQL-client-5.1.49-1.glibc23
第二步：卸载MySQL-server-5.1.49-1.glibc23和MySQL-client-5.1.49-1.glibc23
[plain] view plaincopyprint?
[root@linux ~]# rpm -e MySQL-client-5.1.49-1.glibc23
[root@linux ~]# rpm -e MySQL-server-5.1.49-1.glibc23
第三步：查看有没有mysql服务
[plain] view plaincopyprint?
[root@linux ~]# chkconfig --list | grep -i mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
第四步：删除mysql服务
[plain] view plaincopyprint?
[root@linux ~]# chkconfig --del mysql
第五步：删除分散mysql文件夹
[plain] view plaincopyprint?
[root@linux ~]# whereis mysql
mysql: /usr/lib/mysql /usr/share/mysql
第六步：分别删除
[plain] view plaincopyprint?
[root@linux lib]# rm -rf /usr/lib/mysql/
[root@linux lib]# rm -rf /usr/share/mysql
通过以上步骤就可以卸载干净mysql了。
卸载mysql1、查找以前是否装有mysql
命令：rpm -qa|grep -i mysql
可以看到mysql的两个包：
mysql-*..*.RHEL**
mysqlclient*.RHEL**
2、删除mysql
删除命令：rpm -e --nodeps 包名
( rpm -ev mysql-*.RHEL* )
3、删除老版本mysql的开发头文件和库
命令：rm -fr /usr/lib/mysql
rm -fr /usr/include/mysql
注意：卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除，如果确定没用后就手工删除
rm -f /etc/my.cnf
rm -fr /var/lib/mysql
