    # 设置为自己MYSQL的安装目录 
    basedir=D:Program FilesMySQLMySQL Server 5.7-3306
    # 设置为MYSQL的数据目录 
    datadir=D:Program FilesMySQLMySQL Server 5.7-3306data
    #设置3306端口
    port=3306
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character_set_server=utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
    #开启查询缓存

    mysql 8.0.15 安装步骤有点差异 初始化使用

    mysqld --initialize  --console

    密码会在控制台打印出来

    首次登录需要修改密码,不然使用navicat会提示密码过期

    ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
