Centos6.7下mysql5.5.32忘记数据库的root密码怎么破？

有一天你兴高采烈的准备去连接mysql服务器时间，发现如下一幕，你该怎么办呢？

[root@abao ~]# mysql -uroot -p

Enter password: 

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

不怕，不怕，ABAO阿宝来帮你解决这个问题哈，步骤如下：

1、查看当前安装的mysql版本：

[root@abao ~]# mysql -V

mysql  Ver 14.14 Distrib 5.5.32, for Linux (x86_64) using readline 5.1

2、停止mysql服务：

[root@abao ~]# service mysqld stop

Shutting down MySQL. SUCCESS! 

3、进入到skip-grant-tables模式：

[root@abao ~]# mysqld_safe --skip-grant-tables

170411 00:35:07 mysqld_safe Logging to '/data/abao67.err'.

170411 00:35:07 mysqld_safe Starting mysqld daemon with databases from /data

    此时新打开一个窗口

现在就不需要密码就可以进入mysql了：

[root@abao ~]# mysql

进入mysql系统数据库：

mysql> use mysql

修改root账户密码：

mysql> update user set password=password("12345") where user="root";

刷新权限：

mysql> flush privileges;

mysql> exit

停止mysql进程：

[1]+ Stopped mysqld_safe --skip-grant-tables

启动mysql：

[root@abao ~]# service mysqld start

4、使用刚才修改的密码进入mysql：

[root@abao ~]# mysql -uroot -p12345
