QT5.1+MinGW+免安装MYSQL-5.1.6环境搭建

三部配置:

1.首先QT5.1验证数据库驱动,代码如下:

  QApplication a(argc, argv);
    MainWindow w;
    w.show();
 
 
   qDebug()<<"Available drivers:";
   QStringList drivers = QSqlDatabase::drivers();
   foreach(QString driver, drivers)
   qDebug() <<"\r" << driver;

 	QT5.1默认情况下应为:

"QSQLITE"

"QODBC"

"QODBC3"

"QPSQL"

"QPSQL7" 

没有包含QMYSQL,可以到http://download.csdn.net/download/ljasdf123/5835615下载qt5.1.0的mingw的mysql驱动

解压4个文件安装到你的QT目录下F:\Qt\5.1.0\mingw48_32\plugins\sqldrivers 具体格式安自己的定;

2.下免安装MYSQL-5.1.6环境搭建

解压,然后如下配置:   拷贝 my-huge.ini 另存为my.ini文件 设定字符集为utf8 (切忌不是utf-8)

自己按照解压目录配置环境变量到bin目录下;

D:\mysql\bin>mysqladmin -u root password 新密码

安装到系统服务中 D:\mysql\bin> mysqld --install MySQL5.1.6 --defaults-file=D:\myjweb\mysql\my.ini

启动mysql服务 D:\mysql\bin> NET START MySQL5.1.6  

登陆MySQL D:\mysql -u root -p

Enter password: *********

停止mysql服务 D:\mysql\bin> NET STOP MySQL5.1.6  

3.测试:

    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
        db.setDatabaseName("test"); //该sql库中有个默认的test 具体可以登陆cmd登陆mysql用show databases;命令看
        db.setUserName("root");
        db.setPassword("新密码");
 
 
        bool ok = db.open();
        if (ok == true)
        {qDebug()<< "=========== connect ok =============";
 }else{}
 //db.close() //注释不关闭连接 可以用cmd登陆数据库用mysql> show processlist;看连接数
