具體步驟如下：

1. 從官網(wǎng)下載對應(yīng)的版本。官方網(wǎng)址：mysql服務(wù)下載地址
2. 解壓到本地。我的路徑是：D:\Program Files\mysql-5.7.16-winx64
3. 設(shè)置環(huán)境變量。
   • 添加一個系統(tǒng)變量。變量名：MYSQL_HOME，變量值是mysql的安裝目錄，我這里是：D:\Program Files\mysql-5.7.16-winx64
   • 在Path變量中添加的末尾添加 ;%MYSQL_HOME%\bin
4. 在安裝目錄下新建一個文本文檔，并改名為 my.ini，并添加如下內(nèi)容，保存。

[WinMySQLAdmin]
Server=D:\Program Files\mysql-5.7.16-winx64\bin\mysqld.exe
[mysqld]
basedir=D:\Program Files\mysql-5.7.16-winx64
datadir=D:\Program Files\mysql-5.7.16-winx64\data
port = 3306
server_id = 1
max_connections=1024
log_bin = mysql-bin
explicit_defaults_for_timestamp = TRUE

5. 在安裝目錄下新建一個文件夾命名為data用來存放數(shù)據(jù)。

6. 管理員身份進(jìn)入cmd執(zhí)x行初始化命令:mysqld --initialize --user=mysql --console

C:\Users\Administrator>mysqld --initialize --user=mysql --console
2016-12-07T07:29:17.384477Z 0 [Warning] InnoDB: New log files created, LSN=45790

localhost: x>%B_fO)v1VV

產(chǎn)生一個隨機(jī)密碼，用記事本保存下來：x>%B_fO)v1VV

如果出現(xiàn)了以下警告：

2016-12-07T07:18:13.748519Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see doc
umentation for more details).

檢查你的my.ini 中explicit_defaults_for_timestamp = TRUE是否配置正確

2016-12-07T07:18:13.749519Z 0 [ERROR] --initialize specified but the data direct
ory has files in it. Aborting.

這是前面安裝失敗導(dǎo)致D:\Program Files\mysql-5.7.16-winx64\data下產(chǎn)生了舊數(shù)據(jù)，將舊數(shù)據(jù)刪掉即可。

7. 輸入安裝命令：mysqld --install

C:\Users\Administrator>mysqld --install
Service successfully installed.

表示安裝成功

8. 輸入啟動命令：net start MySQL

C:\Users\Administrator>net start MySQL
發(fā)生系統(tǒng)錯誤 2。
系統(tǒng)找不到指定的文件。

解決辦法：修改mysql注冊表。

開始-->運(yùn)行-->regedit-->HKEY_LOCAL_MACHINE-->SYSTEM-->CurrentControlSet-->services-->mysql(服務(wù)名)-->ImagePath

將ImagePath的路徑更改為：

"安裝目錄\bin\mysqld" --defaults-file="安裝目錄\my.ini" MySql
我這里是：
"D:\Program Files\mysql-5.7.16-winx64\bin\mysqld" --defaults-file="D:\Program Files\mysql-5.7.16-winx64\my.ini" MySql
更改后 服務(wù)成功啟動。

>MySql 服務(wù)正在啟動 .

MySql 服務(wù)已經(jīng)啟動成功。

9. 輸入進(jìn)入mysql命令：mysql -u root -p

   D:\Program Files\mysql-5.7.16-winx64\bin>mysql -u root -p
   Enter password: 這里輸入第6步產(chǎn)生的隨機(jī)密碼

   mysql>

   出現(xiàn)了mysql> 表示成功進(jìn)入到mysql

10. 修改root用戶的初始密碼：set password for root@localhost = password('要修改的密碼');

mysql> set password for root@localhost = password('要修改的密碼');
Query OK, 0 rows affected, 1 warning (0.01 sec)

11. 查看mysql數(shù)據(jù)庫：show databases;

mysql> show databases;
+--------------------+
| Database |
+--------------------+

| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
4 rows in set (0.00 sec)
