准备：
MySQL8.0 Windows zip包下载地址：https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.11-winx64.zip
环境：Windows 10
一、安装
1. 解压zip包到安装目录
我的安装目录是D:/Program Files/mysql-8.0.11-winx64
2.配置文件
windows系统中配置文件默认是安装目录下的 my.ini 文件，部分配置需要在初始安装时配置，大部分也可以在安装完成后进行更改，不知道别人是什么情况，我的是该文件目录下不存在my.ini文件，所以我新建了该文件，如下
写入基本配置如下：
| [mysqld]default_authentication_plugin=mysql_native_password# 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.basedir=D:/Program Files/mysql-8.0.11-winx64datadir=D:/Program Files/mysql-8.0.11-winx64/data(这两行是主要修改的内容，会自动生成data文件夹，其他直接粘贴即可）port = 3306# server_id = .....# Remove leading # to set options mainly useful for reporting servers.# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.# join_buffer_size = 128M# sort_buffer_size = 2M# read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES character-set-server = utf8mb4performance_schema_max_table_instances = 600table_definition_cache = 400table_open_cache = 256[mysql]default-character-set = utf8mb4[client]default-character-set = utf8mb4 |
注意，里面的 basedir 是我本地的安装目录，datadir 是我数据库数据文件要存放的位置，各项配置需要根据自己的环境进行配置。
3.初始化数据库
在MySQL安装目录的 bin 目录下执行命令：
| mysqld --initialize --console |
执行完成后，会打印 root 用户的初始默认密码，比如：
| 2018-05-01T14:35:01.507037Z 0 [Warning] [MY-010915] [Server] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode.
