这是我的密码。mysql在ubuntu设备上。我想我可以访问ubuntu,但是mysql连接失败了
这个php的输出是
Authentication Successful!
tunnel created
test connected
如果我用这条线
$dbconn = mysqli_connect($tunnel,$mysql_user,$mysql_user_pw,$dbname);
则输出为
Authentication Successful!
tunnel created
DBConnection failed:
很明显,$connection和$tunnel没有问题。我已经测试过了。而且效果很好。
请帮帮我!

这与postgresql问题完全相同,因为它们的存在原因相同。你们两个都试图通过ssh隧道通过
ssh2_tunnel
不正确。ssh2_tunnel
返回一个resource
又名afile pointer
