Win10下mysql 8.0.20 安装配置方法图文教程

Win10系统下MySQL 8.0.20安装和配置超详细教程

MySQL下载

MySQL直接去官网下载就行，选择community版本（免费）下载，链接。

在select operating system中选择Microsoft Windows，下方对应出现最新版本的MySQL，目前是MySQL 8.0.20，有两个zip文件，选择第一个Windows (x86, 64-bit), ZIP Archive点击右侧的Download按钮进行下载

官网下载有时速度比较慢，直接点击链接也可以下载：mysql 8.0.20

安装与配置

将下载好的压缩包解压缩到全英文目录下，比如我在D盘新建了MySQL文件夹，解压到该文件夹下，D:/MySQL

然后把mysql 8.0.20所在的路径D:\MySQL\mysql-8.0.20-winx64添加到环境变量Path中

接下来正式安装和配置MySQL：

（一）首先在D:\MySQL\mysql-8.0.20-winx64路径下创建一个my.ini文件，直接新建文本文档，然后重命名为my.ini即可。

在文档中添加以下内容：
（注意修改basedir和datadir的路径）

[mysqld]# 设置3306端口port=3306# 设置mysql的安装目录basedir=D:\\MySQL\\mysql-8.0.20-winx64 # 此处为mysql的解压缩路径# 设置mysql数据库的数据的存放目录datadir=D:\\MySQL\\mysql-8.0.20-winx64\\Data # 此处同上，先不要在路径中创建Data目录，后面初始化时会自动生成# 允许最大连接数max_connections=200# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统max_connect_errors=10# 服务端使用的字符集默认为UTF8character-set-server=utf8# 创建新表时将使用的默认存储引擎default-storage-engine=INNODB# 默认使用“mysql_native_password”插件认证default_authentication_plugin=mysql_native_password[mysql]# 设置mysql客户端默认字符集default-character-set=utf8[client]# 设置mysql客户端连接服务端时默认使用的端口port=3306default-character-set=utf8
