Solution for Mysql error code 1045 under Windows _mysql

Copy Code code as follows:

Error code 1045
Access denied for user ' root ' @ ' localhost ' (using Password:yes)

The workaround is to reset the root password by following the steps in the Windows platform:
1, as a system administrator login to the system;
2, if the MySQL server is running, stop it.
If it is a server running as a Windows service, go to Service Manager: Start menu-> Control Panel-> management tools-> Services
If the server is not running as a service, you may need to use Task Manager to force it to stop.
3. Create 1 text files and place the following commands on a single line:

Copy Code code as follows:

SET PASSWORD for ' root ' @ ' localhost ' = PASSWORD (' Mynewpassword ');

Save the file with any name. In this case, the file is C:\mysql-init.txt.
4, enter the DOS command prompt: Start menu-> run-> cmd
Assume that you have installed MySQL to C:\mysql. If you have MySQL installed in another location, please adjust the following command accordingly.
At the DOS command prompt, execute the command:

Copy Code code as follows:

C:\> C:\mysql\bin\mysqld-nt--init-file=c:\mysql-init.txt

When the server starts, executes the contents of the file named by the "--init-file" option, which reads the SQL command from the specified file at startup, and changes the root user password. After the server has successfully started, you should delete the C:\mysql-init.txt.
5, stop the MySQL server, and then restart it in normal mode. If you run the server as a service, you should start it from the Windows Services window. If you start the server manually, you can use the command as you normally would.
