mysql root password forgotten

问题:

I did not use php mysql for quite a while and now I need to use it again.But problem is I forget the password for mysql console.and getting error #1045 when try to login in phpmyadmin. In mysql site I saw a article how to reset root password( http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html#resetting-permissions-windows)

Steps are
create a mysql-init.txt file containing UPDATE mysql.user SET Password=PASSWORD('newpass') WHERE User='root'; FLUSH PRIVILEGES;

I saved it as C:\me\mysql-init

and in command prompt I wrote-- C:\wamp\bin\mysql\mysql5.5.8\bin\mysqld --init-file=C:\me\mysql-init.txt

I tried with double back slashes also..but it is not working.mysql console is asking for password and its not taking the new-one.What am I doing wrong?I have several tables there.what to do? Thanks in advance.

回答1:

try to start mysql with --skip-grant-tables

mysqld --skip-grant-tables

then connect to your mysqld without username/password using mysql command line

shell> mysql

then issue command

> mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
>        WHERE User='root'; mysql> FLUSH PRIVILEGES;

I couldn't get mysqld in Adelave's answer to work. But this worked for me instead

stop and start mysql with --skip-grant-tables

service mysql.server stop
service mysql.server start --skip-grant-tables

then connect to your mysqld without username/password

mysql

then update the password on mysql command line

 mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; 
 mysql> FLUSH PRIVILEGES;
 mysql> \q

then restart mysql normally

 service mysql.server restart

If other answer could not help, you can try to uninstall/re-install mysql. It works on my ubuntu server:

$sudo apt-get purge mysql*
$sudo apt-get autoremove
$sudo apt-get autoclean

Update distribution

$sudo apt-get dist-upgrade

And re-install

$sudo apt-get install mysql-server
