vt_setting.json文件在哪里？全局配置的数据库设置在里面？请教了。

终于找到了。

{
"font.family": "Arial",
"font.size": 12,
"log.active": true,
"log.level": 50,
"log.console": true,
"log.file": true,
"email.server": "smtp.qq.com",
"email.port": 465,
"email.username": "",
"email.password": "",
"email.sender": "",
"email.receiver": "",
"rqdata.username": "",
"rqdata.password": "",
"database.driver": "MySQL80",
"database.database": "vnpy",
"database.host": "localhost",
"database.port": 3306,
"database.user": "root",
"database.password": "XXXXXXXXX",
"database.authentication_source": "admin"
}

坑太多了，"database.driver": "MySQL80",，竟然认大小写，只能是这样："database.driver": "mysql",

成功了。

【vnpy-community】公众号中有详细的文章介绍。。。
