MySQLERROR 1045 (28000)与ERROR 2002 (HY000)问题解决方法

首先是我遇到的问题是：Access denied for user ‘root’@’localhost’ (using password: YES)，安照网上的方法：

[root@www ~]# mysql -u root -p

Enter password:

ERROR 1045 (28000): Access deniedforuser 'root'@'localhost'(usingpassword: YES)


[root@www ~]#/etc/init.d/mysql stop

[root@www ~]# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

[root@www ~]# mysql -u root mysql

mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root'

mysql> FLUSH PRIVILEGES;

mysql> quit

# /etc/init.d/mysql restart

# mysql -uroot -p

[root@www ~]# mysql -u root -p      #关闭服务后又出现如下问题

Enter password:

ERROR 2002 (HY000): Can'tconnecttolocal MySQL server through socket'/tmp/mysql.sock'(2)
这一步我结合网上的例子：


[root@www ~]#ps -ef|grepmysql
显示类似：

root  18232        00:00:023 mysqld_safe
mysql  18543        00:00:33 mysqld

[root@www ~]#kill -918232

[root@www ~]#kill -918543

[root@www ~]#/etc/init.d/mysql restart

[root@www ~]# mysql -u root -p          ------>重新进入

Enter password:
