ubuntu下qt连接mysql出现 QMYSQL driver not loaded

1、首先检查是否重新安装了MySQL的驱动，可以使用命令：

sudo apt-get remove libqt5sql5-mysql

sudo apt-get install libqt5sql5-mysql

2、重新安装ibmysqlclient-dev即可解决

sudo apt-get remove libmysqlclient-dev

sudo apt-get install libmysqlclient-dev

3、 无法使用127.0.0.1本地和远程登录

mysql -u root -p

GRANT ALL PRIVILEGES ON *.* TO 'your_username'@'%' IDENTIFIED BY 'your_password' WITH GRANT OPTION;

FLUSH PRIVILEGES;

EXIT;

sudo ufw allow 3306

syteamctl restart mysql.service
