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
