MySQL5.6+windows2008怎么没有my.ini配置文件
是有的my.ini配置一些服务参数的，必须有这个文件：查找路径：安装路径\MySQL\MySQL Server 5.6\my.inimy.ini配置内容：# MySQL Server Instance Configuration File# ----------------------------------------------------------------------# Generated by the MySQL Server Instance Configuration Wizard### Installation Instructions# ----------------------------------------------------------------------## On Linux you can copy this file to /etc/my.cnf to set global options,# mysql-data-dir/my.cnf to set server-specific options# (@localstatedir@ for this installation) or to# ~/.my.cnf to set user-specific options.## On Windows you should keep this file in the installation directory # of your server (e.g. C:\Program Files\MySQL\MySQL Server 4.1).

mysql 为什么没有 my-default.ini 配置文件
有没有都没关系，所以mysql 没有 my-default.ini 配置文件。
配置文件是在用户登录一台基于Microsoft Windows XP、Windows 2000或Windows NT? Workstation的计算机上时，系统就会创建一个专用的配置文件。来保存用户的屏幕颜色、网络连接、打印机连接、鼠标设置及窗口的大小和位置等等。
在用户第一次登录到计算机上时被创建，这个本地用户配置文件被储存在计算机的本地硬盘驱动器上。任何对本地用户配置文件所作的更改都只对发生改变的计算机产生作用。
漫游用户配置文件。一个本地配置文件的副本被复制及储存在网络上的一个服务器共享上。当用户每次登录到网络上的任一台计算机上时，这个文件都会被下载，并且当用户注销时，任何对漫游用户配置文件的更改都会与服务器的拷贝同步。漫游用户配置文件要求这台计算机是Windows NT域或Active Directory，的一个成员。
强制用户配置文件。是一种特殊类型的配置文件，使用它管理员可为用户指定特殊的设置。只有系统管理员才能对强制用户配置文件作修改。当用户从系统注销时，用户对桌面做出的修改就会丢失。
编辑mysql配置文件my.ini 可我的mysql里边没有my.ini
mysql 数据库的安装可以分为两种方式：解压方式和安装方式。
两者的区别在于：如果是安装方式，通常会运行一个 向导 程序，当按照向导，一步步完成，mysql 会配置完成，并生成 my.ini。
而 解压 方式，解压完成后，并没有 向导 程序，因此需要手动完成 mysql 的配置，配置文件 mysql 提供了一个缺省的文件，如下图：
将上面的 my-default.ini（由于系统的设置，没有显示 .ini 的扩展名），复制（或直接修改）名为 my.ini 的文件即可。
mysql5.7 为什么没有my.ini
mysql5.7 为什么没有my.ini在老版本的MySQL 3.22中，MySQL的单表限大小为4GB，当时的MySQL的存储引擎还是ISAM存储引擎。但是，当出现MyISAM存储引擎之后，也就是从MySQL 3.23开始，MySQL单表最大限制就已经扩大到了64PB了（官方文档显示）。也就是说，从目前的技术环境来看，MySQL数据库的MyISAM存储 引擎单表大小限制已经不是有MySQL数据库本身来决定，而是由所在主机的OS上面的文件系统来决定了。而MySQL另外一个最流行的存储引擎之一Innodb存储数据的策略是分为两种的，一种是共享表空间存储方式，还有一种是独享表空间存储方式。当使用共享表空间存储方式的时候，Innodb的所有数据保存在一个单独的表空间里面，而这个表空间可以由很多个文件组成，一个表可以跨多个文件存在，所 以其大小限制不再是文件大小的限制，而是其自身的限制。从Innodb的官方文档中可以看到，其表空间的最大限制为64TB，也就是说，Innodb的单 表限制基本上也在64TB左右了，当然这个大小是包括这个表的所有索引等其他相关数据。而当使用独享表空间来存放Innodb的表的时候，每个表的数据以一个单独的文件来存放，这个时候的单表限制，又变成文件系统的大小限制了。
安装mysql没有my.ini文件
打开cmd（记得”使用管理员身份“打开），如果没有配置环境变量，请cd（切换目录）到mysql程序下的bin文件夹下 执行命令 D:\mysql\mysql-5.7.29-winx64\bin "MySql"为服务名称，你的MysSql服务不一定是这个名称，可以打开电脑的服务窗口查看。 删除完成之后，最好去电脑的服务窗口看下，如果找不到MySql服务，说明已经已经删除成功。 如果还能看到MySql服务，可以手动右击选择”停止“，服务停止之后就会自动消失了。 在mysql程序的根目录下，新建一个my.ini空白文件，用记事本打开，将以下内容复制进去 # For advice on how to change settings please see ***隐藏网址*** # *** DO NOT EDIT THIS FILE. It’s a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. default-character-set = utf8mb4 default-character-set = utf8mb4 character-set-client-handshake = FALSE character-set-server = utf8mb4 collation-server = utf8mb4_bin init_connect=’SET NAMES utf8mb4’ # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL.
