windows系统安装mysql8 解压缩版安装顺序

1.下载mysql zip包并解压到指定目录：

下载地址：https://dev.mysql.com/downloads/mysql/（一般下载第一个链接，如文件名称：mysql-8.0.32-winx64.zip）

2.配置环境变量（我的电脑右键属性->高级系统设置->环境变量）：

在系统变量下点击新建
  变量名称为MYSQL_HOME，变量值为自己刚才解压后的目录位置，如：D:\datastorage\mysql-8.0.32-winx64

3.在系统变量里找到path进行编辑

在最后面新增：%MYSQL_HOME%\bin

4.在解压目录(如：D:\datastorage\mysql-8.0.32-winx64)新建my.ini或my-default.ini文件
ini文件内容如下：

[mysql]

# 设置mysql客户端默认字符集

# default-character-set=utf8

default-character-set=utf8mb4

[mysqld]

# 绑定IPv4

# bind-address=0.0.0.0

#bind-address=127.0.0.1

# 设置端口号

port=13306

# 设置mysql的安装目录，即解压目录

basedir=D:\\datastorage\\mysql-8.0.32-winx64

# 设置数据库的数据存放目录

datadir=D:\\datastorage\\mysql-8.0.32-winx64\\data

# 设置允许最大连接数

max_connections=200

# 设置允许连接失败次数

max_connect_errors=10

# 设置服务端的默认字符集

# character-set-server=utf8

character-set-server=utf8mb4

#character_set_database=utf8mb4

#character_set_system=utf8mb4

#collation_connection=utf8mb4_unicode_ci

#collation_server=utf8mb4_unicode_ci

# 创建表使用的默认存储引擎

default-storage-engine=INNODB

# 使用“mysql_native_password”插件认证

default_authentication_plugin=mysql_native_password

#解决This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)

log-bin-trust-function-creators=1

max_allowed_packet=1024M

wait_timeout=288000

interactive_timeout = 288000

secure_file_priv =

ini内配置的端口等根据自己需求修改，其中，datadir和basedir文件夹的路径可以根据个人喜好配置（尽量不使用中文），没有datadir中data目录，需手动创建一个目录（没有data目录，有可能会报错），保证此目录为空，不能包含任何文件

5.cmd用管理员身份进入D:\datastorage\mysql-8.0.32-winx64\bin目录，命令如：
C:\Windows\System32>d:

D:\>cd D:\datastorage\mysql-8.0.32-winx64

D:\datastorage\mysql-8.0.32-winx64> cd bin

D:\datastorage\mysql-8.0.32-winx64\bin>

6.安装服务命令：mysqld -install mysql8032 --defaults-file=D:\datastorage\mysql-8.0.32-winx64\my.ini，执行后如下：

D:\datastorage\mysql-8.0.32-winx64\bin>mysqld -install mysql8032 --defaults-file=D:\datastorage\mysql-8.0.32-winx64\my.ini
Service successfully installed.

D:\datastorage\mysql-8.0.32-winx64\bin>

7.进行mysql的初始化：
mysqld --initialize --console
执行后如下：
D:\datastorage\mysql-8.0.32-winx64\bin>mysqld --initialize --console
2023-03-28T01:53:36.578461Z 0 [Warning] [MY-010918] [Server] 'default_authentication_plugin' is deprecated and will be removed in a future release. Please use authentication_policy instead.
2023-03-28T01:53:36.578743Z 0 [System] [MY-013169] [Server] D:\datastorage\mysql-8.0.32-winx64\bin\mysqld.exe (mysqld 8.0.32) initializing of server in progress as process 16332
2023-03-28T01:53:36.724235Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2023-03-28T01:53:43.447654Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2023-03-28T01:53:48.119291Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: vFTvoYp7?_39

此时要记住自己的初始化密码：vFTvoYp7?_39

8.启动服务：
D:\datastorage\mysql-8.0.32-winx64\bin>net start mysql8032
mysql8032 服务正在启动 ..
mysql8032 服务已经启动成功。

D:\datastorage\mysql-8.0.32-winx64\bin>

9.使用root登录：

登录密码为上面第7步初始化的密码 vFTvoYp7?_39 ，执行如下：
D:\datastorage\mysql-8.0.32-winx64\bin>mysql -uroot -P13306 -p
Enter password: ************

10.修改root密码：
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysql82023';
执行后如下：
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysql82023';
Query OK, 0 rows affected (0.04 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

mysql>

11.设置远程登录：

mysql8.0之前，创建一个mysqla用户，允许所有IP访问，密码是mysql82023

GRANT ALL PRIVILEGES ON *.* TO 'mysqla'@'%' IDENTIFIED BY 'mysql82023' WITH GRANT OPTION;

但是从MySQL8版本开始，不能再使用GRANT创建用户，而是要先CREATE USER，然后使用GRANT授权

CREATE USER 'mysqla'@'%' IDENTIFIED BY 'mysql82023';

GRANT ALL PRIVILEGES ON *.* TO 'mysqla'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

执行后如下：
mysql> CREATE USER 'mysqla'@'%' IDENTIFIED BY 'mysql82023';
Query OK, 0 rows affected (0.03 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'mysqla'@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.03 sec)

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

mysql>

12使用新创建的用户登录：
先退出root账号登录，执行后如下：
mysql> exit;
Bye

D:\datastorage\mysql-8.0.32-winx64\bin>mysql -umysqla -P13306 -p
Enter password: **************

备注，使用root用户远程链接：

mysql8.0 root 开启远程访问
修改密码：ALTER USER 'root'@'localhost' IDENTIFIED BY 'mysql82023';

创建root远程用户：
CREATE USER 'root'@'%' IDENTIFIED BY 'mysql82023';

GRANT ALL ON *.* TO 'root'@'%';

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'mysql82023';

FLUSH PRIVILEGES;

13.到此步骤即可使用工具进行数据库连接了，仅为安装方便做个记录。
