news 2025/7/13 6:24:51

1）下载

mysql5.6.51介质下载地址：https://downloads.mysql.com/archives/community/

2）下载后解压到D:或E：

3）创建环境变量

4）配置参数

my.ini参数如下

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
basedir = E:\mysql-5.6.51-winx64
datadir = E:\mysql-5.6.51-winx64\data
port = 3306
# server_id = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

my-default.ini参数如下：

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld]
character-set-server=utf8mb4
[mysql]
default-character-set=utf8mb4

以管理员身份运行cmd（不然权限不够），通过命令进入mysql bin 目录运行命令|：

mysqld --initialize-insecure --user=mysql

再次执行如下命令

mysql -hlocalhost -uroot -p

netstat -ano|findstr 3306

mysqld -install

到此说明mysql 已经安装成功。

注意如发现mysql服务安装路径不对可通过指令sc delete MySQL进行删除后再安装；

启动mysql服务：命令如下
E:\mysql-5.6.51-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。

5）用户登录及实际操作

mysql -u root -p第一次登录无密码。

查看数据库：show databases;
创建数据库：create database dbai;
进入数据库：use dbai;
使用查看当前数据库的表：show tables;
user表如果没有创建：create table user(username varchar(8),password varchar(8));
向表里添加数据：insert into user(username,password) values('admin','1234');
insert into user(username,password) values('user1','1111');
然后查看user表：select * from user;

创建新表格

create table bearnumsex(id varchar(6),DateTime datetime,swimgap FLOAT(5,2),innersize1 int(6),innersize2 int(6),unit varchar(50),date varchar(10),type varchar(10),repair varchar(10),imgpath varchar(50));

alter table bearnumsex convert to character set utf8mb4 collate utf8mb4_bin; 更新表格使其支持中文

6)问题处理

问题1：程序运行访问数据库提升如下：数据库打开失败 Access denied for user 'root'@localhost (using password:YES) QMYSQL:Unable to connect

处理方法：请参考：在MySQL登录时出现Access denied for user ‘root‘@‘localhost‘ (using password YES) 拒绝访问问题解决_mysql显示access denied for user-CSDN博客

问题2：

QSqlDatabase: QMYSQL driver not loaded

QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

处理方法：将mysql数据路径lib下的lib和dll放到Qt程序的可执行程序下。
