Generally this error is caused by a password error, the solution is to reset the password.

Let's say we're using the root account.

1. The first step in resetting the password is to skip the MySQL password authentication process, as follows:

#vim/etc/my.cnf (Note: My.ini is modified under Windows)

Search within a document MYSQLD navigate to the [mysqld] text segment:
/mysqld (enter the command directly in the Vim edit state to search for text content)

Add "skip-grant-tables" to skip password verification on any line following [Mysqld], as shown in:

Save the document and exit:

2. Next we need to restart MySQL:

/etc/init.d/mysql Restart (some users may need to use/etc/init.d/mysqld restart)

3. After reboot, enter #mysql to enter MySQL

4. The next step is to use SQL to modify the root password

mysql> use MySQL;
mysql> Update user Set Password=password ("Your new password") where user= "root";
mysql> flush Privileges;
Mysql> quit


If MySql5.7 is executed: mysql> update user set Password=password ("Your new password") where user= "root"; This step will be an error: The following:

ERROR 1054 (42S22): Unknown column ' Password ' in ' Field list '

Reason: mysql5.7 No password field, replace with authentication_string

WORKAROUND: Update user set Password=password ("Your new password") where user= "root"; Instead: Update mysql.user set Authentication_string=password (' root ') where user= ' root ';

The root account has been reset to the new password.

5. Edit the my.cnf, remove the content you just added, and then restart MySQL. Done!

There are a lot of solutions to this problem on the Internet, many of the friends who have just contacted may be confused to find my.cnf or My.ini files on their own platform, if you are Linux, you can search by using the following methods:

As for the Windows platform, go to the installation directory and look for My.ini.
