根据需要下载对应版本MySQL

接下来，点击Download，选择No thanks, just start my download就会直接下载安装包。

二：配置环境变量  
新建MYSQL\_HOME变量，变量名为你的解压路径名

编辑path变量，在末尾加上 ;%MYSQL\_HOME%\\bin;

三：解压安装包到指定路径-------my.ini文件  
1. 下载完成后解压到你想要放的目录（5.7.20左右的版本（至少5.7.20是），没my-default.ini这个文件了）

2. 在bin的同级目录，新建my-default.ini文件。我的ini文件是这样的：

\[mysqld\]  
port = 3306  
basedir=D:\\tools\\mysql-5.7.24-winx64  //mysql安装目录  
datadir=D:\\tools\\mysql-5.7.24-winx64/data  
max\_connections=200  
character-set-server=utf8  
default-storage-engine=INNODB  
sql\_mode=NO\_ENGINE\_SUBSTITUTION,STRICT\_TRANS\_TABLES  
\[mysql\]  
default-character-set=utf8

3. 在bin目录下面，新建（或者复制my-default.ini）my.ini文件，不然初始化mysqld --initialize-insecure, data文件会报找不到文件夹（不能自动生成data文件夹）

我的my.ini：

\# For advice on how to change settings please see  
\# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html  
\# \*\*\* 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.

\[mysqld\]

\# 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:\\tools\\mysql-5.7.24-winx64  //mysql安装目录  
datadir = D:\\tools\\mysql-5.7.24-winx64\\data  
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

四：安装MySQL服务以及初始化

以管理员身份运行cmd，

# **以下所有命令都需要进入到mysql安装目录的bin目录下进行！！！** #

执行安装mysql服务的命令：mysqld --install

mysqld --install

我们可以看到服务已经成功安装。

假设这里出现安装不成功，那么就有可能是你之前安装了但是卸载不完全导致的，所以一定要卸载完整。

初始化MySQL：

mysqld --initialize

初始化完成后会出现data文件夹

如果有data文件夹了，先删除掉，再执行mysqld --initialize.

然后启动MySQL：

net start mysql

MySQL登录：mysql -u root -p

注意：初始密码可以在生成的data文件夹下后缀名为.err的文件

然后设置自己的登录密码：

alter user user() identified by "你的新密码";

mysql>FLUSH PRIVILEGES; //刷新权限
