    $password = "123456";
     

    $conn = mysqli_connect($servername, $username, $password);
    if (!$conn) {
        die("Connection failed: " . mysqli_connect_error());
    }
    echo "Connection finished!";
    ?>

3，在conf创建nginx配置文件

            location / {
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ =404;
            }

            # pass PHP scripts to FastCGI server
