官網(wǎng)下載并解壓mysql-5.7.25-winx64.zip，然后配置環(huán)境變量

在解壓的目錄下創(chuàng)建data文件夾用于存放數(shù)據(jù)，再創(chuàng)建my.ini配置文件，內(nèi)容如下:

[mysqld]

#設(shè)置3306端口

port = 3306

# 設(shè)置mysql的安裝目錄

basedir=F:\\software-school\\mysql-5.7.25

# 設(shè)置mysql數(shù)據(jù)庫(kù)的數(shù)據(jù)的存放目錄

datadir=F:\\software-school\\mysql-5.7.25\\data

# 允許最大連接數(shù)

max_connections=200

# 服務(wù)端使用的字符集默認(rèn)為8比特編碼的latin1字符集

character-set-server=utf8

# 創(chuàng)建新表時(shí)將使用的默認(rèn)存儲(chǔ)引擎

default-storage-engine=INNODB

注意: 這里文件目錄要使用雙斜杠

以管理員權(quán)限打開cmd窗口，輸入以下命令

1、mysqld --initialize --user=mysql --console 初始化數(shù)據(jù)庫(kù)，在data目錄里生成數(shù)據(jù)文件，會(huì)生成一個(gè)默認(rèn)密碼,復(fù)制好密碼, 以便待會(huì)兒修改密碼：

C:\WINDOWS\system32>mysqld --initialize --user=mysql --console

2、mysqld -install 安裝MySQL服務(wù)

C:\WINDOWS\system32>mysqld -install

Service successfully installed.

3、net start mysql 啟動(dòng)MySQL服務(wù)

C:\WINDOWS\system32>net start mysql

MySQL 服務(wù)正在啟動(dòng) .

MySQL 服務(wù)已經(jīng)啟動(dòng)成功。

4、mysql -u root -p 輸入剛才的復(fù)制的默認(rèn)密碼，登陸mysql

C:\WINDOWS\system32>mysql -uroot -p

Enter password: ************

mysql>

5、SET PASSWORD FOR 'root'@'localhost' = PASSWORD('garcon'); 修改密碼

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('garcon');

Query OK, 0 rows affected, 1 warning (0.00 sec)

到此安裝完成

總結(jié)
