fedora 下mysql root密码重置

<!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } -->

首先启动mysql 服务

[han@localhost ~]$ sudo service mysqld start

启动 MySQL ： [ 确定]

 

看看mysql 服务有没有起来

[han@localhost ~]$ sudo netstat -tap |grep mysql

tcp 0 0 *:mysql *:* LISTEN 4386/mysqld

 

修改root 密码，因为我实在记不得了

[han@localhost ~]$ mysqladmin -u root password root

mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: NO)'

 

报错，上网搜索解决方法，如下执行

[han@localhost ~]$ su

密码：

[root@localhost han]# /etc/init.d/mysqld stop

停止 MySQL ： [ 确定]

 

[root@localhost han]# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

[1] 4567

[root@localhost han]# nohup: ignoring input and redirecting stderr to stdout

You can turn off this feature to get a quicker startup with -A

[root@localhost han]# mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

 

出错，重试

[root@localhost han]# mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

 

依然报错，再次上网搜索解决办法，执行如下

[root@localhost han]# /etc/init.d/mysql stop

bash: /etc/init.d/mysql: 没有那个文件或目录

 

拷贝的命令不对，fedora 和ubuntu 的命令不一样，在试

[root@localhost han]# /etc/init.d/mysqld stop

停止 MySQL ： [ 确定]

[root@localhost han]# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
