Question

起初，我创建的文件上传系统存在问题，因为我没有上传文件的权限（本地主机xampp）。我真的不知道我在linux jet周围的方式，所以我在论坛上读过一些命令chmod和chown，这让我变得更糟。我mysqli无法连接。我希望有人知道我坏了吗？

<?php
    session_start();
    $servername = "localhost";
    $username = "root";
    $password = "";
    $dbname = "visitbled";
    $conn = new mysqli($servername, $username, $password, $dbname);
    mysqli_set_charset($conn,"utf8");
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 

?>

我用过的一些命令

sudo chmod +rwx /opt/lampp/htdocs/bled/osnovnideli/
sudo chmod R 0755 /opt/lampp
sudo chown andrej /opt/lampp/htdocs/bled/

错误：

Warning: mysqli::__construct(): (HY000/2002): Permission denied in /opt/lampp/htdocs/bled/osnovnideli/global.php on line 7

Warning: mysqli_set_charset(): Couldn't fetch mysqli in /opt/lampp/htdocs/bled/osnovnideli/global.php on line 8
Connection failed: Permission denied

编辑：尝试连接数据库时，phpMyAdmin也会发生相同的问题

警告：mysqli :: __ construct（）：（HY000 / 2002）：权限被拒绝
