一、下载mysql8.rar解压到C盘(也可以解压到其他位置)

在系统环境变量添加JAVA_HOME=C:\myslq8，并在path中添加%JAVA_HOME%\bin;

二、以管理员身份进入命令窗口

三、修改配置文件指定安装路径和数据库的存放路径

四、键入如下命令初始化并启动mysql服务,然后修改登录密码

C:\>mysqld --initialize --user=mysql --console
C:\>mysqld -install
C:\>net start MySQL
C:\>mysql -u root -p （回车让输入的密码就是第一个命令后出现的临时密码）
mysql> ALTER USER root@localhost IDENTIFIED BY "12345678"; （新修改密码自己指定）
mysql> flush privileges;
mysql> exit

五、手动命令建数据库的命令如下

C:\> mysql -u root -p
Enter password: ******** （上面自己修改的新密码）
Welcome to the MySQL monitor. Commands end with ; or \g.

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

mysql> create testdatabase; （创建的数据库为testdatabase）
mysql> use testdatabase; （切换到刚建的数据库）
mysql> create table customers (id INT PRIMARY KEY AUTO_INCREMENT,name VARCHAR(255),address VARCHAR(255),city VARCHAR(255)); （创建表customers）
mysql> insert into customers (name,address,city) values('张三','海淀区','北京'); （插入新记录）
mysql> select * from customers; （显示新记录）
+----+--------+-----------+--------+
| id | name | address | city |
+----+--------+-----------+--------+
| 1 | 张三 | 海淀区 | 北京 |
+----+--------+-----------+--------+
1 row in set (0.00 sec)

六、VS2022调试读取源代码如下

// TestMySQL.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//#include <stdio.h>
#include <iostream>
#include "include/mysql.h"using namespace std;
#pragma comment(lib,"lib/libmysql.lib")int main()
{MYSQL mysql;mysql_init(&mysql);if (!(mysql_real_connect(&mysql, "127.0.0.1", "root", "12345678", "testdatabase", 0, NULL, 0))){cout << "Connect database,fail!\n : ";cout << mysql_error(&mysql);exit(-1);}mysql_query(&mysql, "set names gbk");mysql_query(&mysql, "select * from customers where name = '张三'");MYSQL_RES* res = mysql_store_result(&mysql);if (res == NULL){mysql_close(&mysql);cout << mysql_error(&mysql);exit(-1);}MYSQL_ROW row;int count = mysql_num_fields(res);while (row = mysql_fetch_row(res)){for (int kkk = 0; kkk < count; kkk++){cout << row[kkk] << "\t";}cout << endl;}mysql_free_result(res);mysql_close(&mysql);return 0;
}

七、编译时前要把mysql依赖库和包含文件拷贝到工程下
