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:
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:

[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utf8
character - 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=3306
default - character - set =utf8
