Mysql下载地址：[https://dev.mysql.com/downloads/mysql/][https_dev.mysql.com_downloads_mysql]

根据电脑位数下载相应的zip文件包（还有.msi的文件，那个安装过程略）

配置好相应变量后，安装mysql：mysqld -install 并初始化：mysqld --initialize

启动Mysql:

在mysql根目录下的my.ini下\[mysqld\]下添加一句代码 “skip-grant-tables”如下：

[client]
    
    port=3306
    default-character-set=utf8
    
    [mysqld]
    
    # Remove leading # and set to the amount of RAM for the most important data
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    # innodb_buffer_pool_size = 128M
    
    # Remove leading # to turn on a very important data integrity option: logging
    # changes to the binary log between backups.
    # log_bin
    
    # These are commonly set, remove the # and set as required.
    
    character-set-server = utf8
    port = 3306
    
    bind-address = 127.0.0.1
    
    basedir=D:\mysql-5.7.27-winx64
    
    # 设置为MYSQL的数据目录 
    datadir=D:\mysql-5.7.27-winx64\data
    
    
    #开启查询缓存
    explicit_defaults_for_timestamp=true
    
    skip-grant-tables

保存后，再重新启动MySQL。

登入mysql：在输入密码一栏，直接回车跳过，便会自动跳过输密码直接进入。

之后执行以下语句（不要忘了加分号！）

若出现下面的错误

解决办法：先执行 flush privileges; 再执行一次上次指令即可，如下：

然后退出，将my.ini中的 skip-grant-tables 删除掉，保存，然后重启Mysql，再次登录便需要密码。
