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 &

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 &
