2、考慮到資料庫容量會增加，建議解壓縮到可用容量較大的碟符，我解壓縮到D盤；

3、進入解壓縮目錄，新建my.ini檔案，內容如下：

[mysqld]
# set basedir to your installation path
basedir=D:/mysql-5.7.22-winx64
# set datadir to the location of your data directory
datadir=D:/mysql-5.7.22-winx64/data

4、使用cmd進入解壓縮目錄下的bin/目錄下

# 安裝mysql服務，安裝完成後，可在右鍵“計算機”-“管理”-“服務”中看到，預設服務名為“MySQL”，也可以在install後面指定服務名稱
D:\mysql-5.7.22-winx64\bin>mysqld install
Service successfully installed.
 

# 初始化data目錄
D:\mysql-5.7.22-winx64\bin>mysqld.exe --initialize

初始化後會在datadir路徑下生成一個*.err的檔案，開啟如下：

2018-05-27T04:49:08.182952Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2018-05-27T04:49:11.696958Z 1 [Note] A temporary password is generated for 
 
[email protected]: q&10*I#<fi-w

最後一行“A temporary password is generated for [email protected]: q&10*I#<fi-w”冒號後面的就是臨時密碼；

# 啟動MySQL服務
D:\mysql-5.7.22-winx64\bin>net start mysql
MySQL 服務正在啟動 .
MySQL 服務已經啟動成功。

5、修改密碼

後面有兩種方式可以修改密碼，一種是使用剛才生成的臨時密碼登入修改，另一種是修改配置檔案跳過密碼登入然後修改密碼；

5.1 通過臨時密碼登入

# 使用臨時密碼登入
E:\mysql-5.7.22-winx64\bin>mysql -u root -p
Enter password: ************
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.7.22

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

# 檢視埠號
mysql> show global variables like 'port';
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
# 通過ALTER語句修改密碼
mysql> ALTER user 'root'@'localhost' identified by 'Jiubugaosuni_01';
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW GLOBAL VARIABLES LIKE 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set, 1 warning (0.01 sec)

5.2 跳過密碼登入

5.2.1 跳過密碼登入MySQL

# 停止MySQL服務
D:\mysql-5.7.22-winx64\bin>net stop mysql
MySQL 服務正在停止.
MySQL 服務已成功停止。

# 解除安裝MySQL服務
D:\mysql-5.7.22-winx64\bin>mysqld remove
Service successfully removed.

# 編輯my.ini配置檔案，在[mysqld]下新增skip-grant-tables
[mysqld]
# set basedir to your installation path
basedir=D:/mysql-5.7.22-winx64
# set datadir to the location of your data directory
datadir=D:/mysql-5.7.22-winx64/data
skip-grant-tables

# 安裝MySQL服務
D:\mysql-5.7.22-winx64\bin>mysqld install
Service successfully installed.

# 啟動MySQL服務
D:\mysql-5.7.22-winx64\bin>net start mysql
MySQL 服務正在啟動 .
MySQL 服務已經啟動成功。

5.2.2 無密碼登入

D:\mysql-5.7.22-winx64\bin>mysql -u root -p
Enter password:（回車，無需輸入密碼）
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

mysql>

# 在這裡不能使用ALTER語句，否則報錯
mysql> ALTER user 'root'@'localhost' identified by 'Jiubugaosuni_01';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this
statement

# 而應該使用如下命令，設定臨時密碼
mysql> use mysql;
Database changed
mysql> UPDATE user SET authentication_string = password("Jiubugaosuni_01") WHERE user = "root";
Query OK, 1 row affected, 1 warning (0.07 sec)
Rows matched: 1  Changed: 1  Warnings: 1

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> QUIT;
Bye

5.2.3 恢復密碼登入

# 停止MySQL服務
D:\mysql-5.7.22-winx64\bin>net stop mysql
MySQL 服務正在停止.
MySQL 服務已成功停止。

# 解除安裝MySQL服務
D:\mysql-5.7.22-winx64\bin>mysqld remove
Service successfully removed.

# 修改my.ini配置檔案，註釋或者刪除skip-grant-tables
[mysqld]
# set basedir to your installation path
basedir=D:/mysql-5.7.22-winx64
# set datadir to the location of your data directory
datadir=D:/mysql-5.7.22-winx64/data
# skip-grant-tables

# 安裝MySQL服務
D:\mysql-5.7.22-winx64\bin>mysqld install
Service successfully installed.

# 啟動MySQL服務
D:\mysql-5.7.22-winx64\bin>net start mysql
MySQL 服務正在啟動 .
MySQL 服務已經啟動成功。

5.2.4 登入並檢視埠號

# 使用修改的臨時密碼登入
D:\mysql-5.7.22-winx64\bin>mysql -u root -p
Enter password: ***************
Welcome to the MySQL monitor.  Commands end with ; or \g.

# 必須通過ALTER語句修改密碼才算正式修改密碼成功
mysql> show global variables like 'port';
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> ALTER user 'root'@'localhost' identified by 'Jiubugaosuni_01';

6、配置遠端登入

# 賦予全部許可權在所有資料庫和所有表上給root使用者在任何主機上使用Jiubugaosuni_01這個密碼登入  
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Jiubugaosuni_01' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.02 sec)
