新手在这个上往往容易范错误,导致不能进入MYSQL,整得非常郁闷。 我来做几个例子相信很快就明白了 。 1、原来的密码是123456 C:\>type mysql5.bat @echo off mysql -uroot -p123456 -P3306 正确的修改MYSQL用户密码的格式是: 我们这里用 用户:root(可以换成其他的) 密码:woshiduide 来演示新密码。
C:\>mysqladmin -uroot -p password woshiduide Enter password: ****** 于是修改成功。 注意PASSWORD关键字后面的空格
有好多人是这样修改的: C:\>mysqladmin -uroot -p password 'woshiduide' Enter password: ******
C:\>mysqladmin -uroot -p password 'woshiduide' Enter password: ********* Warning: single quotes were not trimmed from the password by your command line client, as you might have expected.
而这个时候真正的密码是'woshiduide'
C:\>mysql -uroot -p'woshiduide' Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 18 Server version: 5.1.17-beta-community-nt-debug MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
而新手往往这样: C:\>mysql -uroot -pwoshiduide ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: Y ES) 所以非常郁闷,BAIDU、GOOGLE的搜了一大堆。
我现在把密码改回去。 C:\>mysqladmin -uroot -p'woshiduide' password 123456
2、还有就是可以直接进入MYSQL,然后修改密码。
mysql> use mysql Database changed mysql> update user set PASSWORD = PASSWORD('woshiduide') where USER='root' and H OST='localhost'; Query OK, 1 row affected (0.05 sec) Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
mysql> exit Bye
C:\>mysql -uroot -pwoshiduide Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 23 Server version: 5.1.17-beta-community-nt-debug MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> Query OK, 0 rows affected (0.02 sec) 3、还有一种就是用SET PASSWORD 命令修改:
C:\>mysql5.bat Enter password: ****** Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 8 Server version: 5.1.17-beta-community-nt-debug-log MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> set password for root@'localhost' = password('woshiduide'); Query OK, 0 rows affected (0.02 sec)
mysql> flush privileges; Query OK, 0 rows affected (0.09 sec)
mysql> exit Bye 4、GRANT 也可以,不过这里不介绍。因为涉及到权限的问题。
