原理:通过跳过表授权,跳过密码直接在表里更新密码

  1. 1. 找到my.ini一般在C:\Program Files\MySQL\MySQL Server 5.7\bin

    ...
    [mysqld]

    # The next three options are mutually exclusive to SERVER_PORT below.
    # skip-networking

    # enable-named-pipe

    找到这个片段,改为

    skip-grant-tables
    # The next three options are mutually exclusive to SERVER_PORT below.
    # skip-networking

    # enable-named-pipe
