I have moved my xampp server to raspbian for image uploading. I can access the server, folder via browser and can see that image was registered in DB but unfortunately there is no image at that folder.
If you need more specific information let me know.
My phone app: https://gist.github.com/DoIReallyNeedIt/a068c69958f269ad1d1a373d9ec8bcdb
Connection to server:
<?php
$user_name = "root";
$user_pass = "root";
$host_name = "localhost";
$db_name = "mydb";
$con = mysqli_connect ($host_name, $user_name, $user_pass, $db_name);
if ($con)
{
$image = $_POST["image"];
$name =date('Y').date('m').date('d'). "_" . date('H'). date('i'). "_". $_POST["name2"]."_".$_POST["name1"];
$sql = "insert into imageinfo(name) values ('$name')";
$upload_path = "uploads/$name.jpg";
if(mysqli_query($con,$sql)){
file_put_contents ($upload_path, base64_decode($image));
echo json_encode (array ('response'=>'Nuotrauka buvo sėkmingai įkelta'));
}
else {
echo json_encode (array ('response'=>'Nuotraukos įkelti nepayvko'));
}
}
mysqli_close($con);
?>
Found the problem. For some reason chmod didn't saved for folders

I have implemented app on adionisjs framework and I want to deploy it on godaddy shared server, is there is any way to do that?
You cannot deploy nodejs app on a shared server directly, because the shared server is configured with server name not with the port, so instead, you can use PHP to run nodejs app.
<?php
//Choose JS file to run
$file = 'node_modules/jt-js-sample/index.js';
//Spawn node server in the background and return its pid
$pid = exec('PORT=49999 node/bin/node ' . $file . ' >/dev/null 2>&1 & echo $!');
//Wait for node to start up
usleep(500000);
//Connect to node server using cURL
$curl = curl_init('http://127.0.0.1:49999/');
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//Get the full response
$resp = curl_exec($curl);
if($resp === false) {
//If couldn't connect, try increasing usleep
echo 'Error: ' . curl_error($curl);
} else {
//Split response headers and body
list($head, $body) = explode("\r\n\r\n", $resp, 2);
$headarr = explode("\n", $head);
//Print headers
foreach($headarr as $headval) {
header($headval);
}
//Print body
echo $body;
}
//Close connection
curl_close($curl);
//Close node server
exec('kill ' . $pid);
I am trying to access an sqlite file on a local area network machine located in "sqlite" folder, on windows file explorer I access it using the IP address "192.168.5.15/sqlite/db.sqlite", however when the electron aplication tries to access it, the path is converted to the local machine path "c:/application ....../192.168 ....".
please how can I just point the file directly using the static IP adress without converting it to local machine path?
here is the code:
// login_app.js
var route = require('../../libs/router.js'); //my lib
var dbPath = "192.168.5.15/sqlite/db.sqlite" // here is the path i want to keep it static
function login() {
var email = document.getElementById("email").value;
var password = document.getElementById("password").value;
if(email == "" || password == ""){
alert("Please Enter Your email & Password ...");
return;
} else{
var sql = require('sql.js'); //Import sqLite
var fs = require("fs"); //Import Files driver
var SHA256 = require("crypto-js/sha256"); //Crypting Library
try {
var filebuffer = fs.readFileSync(dbPath); //here is the problem it converts the file to local machine path c:/..../192....
if (filebuffer != null) {
var db = new SQL.Database(filebuffer);
} else {
var db = new SQL.Database();
console.log("No Database");
}
// Prepare an sql statement
var stmt = db.prepare("SELECT * FROM users WHERE email=:emailid");
// Bind values to the parameters and fetch the results of the query
var result = stmt.getAsObject({':emailid' : email});
if(result.password == null) alert('Account not existing, please contact Your Administrator ...');
else{
if(SHA256(password) == result.password) {
route.data.relocate('dashboard');
}
else alert('Wrong Login credentials, please try again ...');
}
} catch (e) {
console.log(e);
}
}
}
as suggested by GregHNZ var dbPath = "//192.168.5.15/sqlite/db.sqlite" worked, so just used double slash.
Thanks GregHNZ
I am trying to create eJabberd users using PHP script.
The following script is working perfectly on my local system(Ubuntu 14.04) :
<?php
error_reporting(E_ALL);
ini_set('display_errors', '-1');
$username = 'userx1';
$password = '123456';
$node = 'localhost';
exec('ssh -t -t <hostname> ejabberdctl register '.$username.' '.$node.' '.$password.' 2>&1', $output, $status);
if($output == 0)
{
echo "User created successfully.";
}
else
{
// Failure, $output has the details
echo '<pre>';
foreach($output as $o)
{
echo $o."\n";
}
echo '</pre>';
}
But when I am trying to run on the server(CentOS).
Its giving me following error :
Host key verification failed.
I tried some solutions like :
https://askubuntu.com/questions/45679/ssh-connection-problem-with-host-key-verification-failed-error
https://www.youtube.com/watch?v=IJj0uD7EgGk
but no success.
Any reference will be very helpful. Thanks in advance.
Found A better way to crate user to eJabberd server.
mod_rest :
https://github.com/processone/ejabberd-contrib/tree/master/mod_rest
Provides you to make REST calls to the server.
I have 2 servers, one of them has the application for upload images and the folder that save the images is in the other server
So, how can i do that?? (connect the application with the folder in the other server)
If you upload your images with php, a solution is to upload via ftp the image to your second server (with folders to save images) from the first server.
You need :
private function ftpConnnect($ftp_server, $ftp_user_name, $ftp_user_pass)
{
// set up basic connection
$conn_id = ftp_connect($ftp_server);
if(ftp_login($conn_id, $ftp_user_name, $ftp_user_pass))
{
echo "Logged In\n";
}
else
{
echo "Not Logged In\n";
}
ftp_pasv($conn_id, true);
return $conn_id;
}
private function uploadOnServer($path, $saved_to, $ftp, $ftp_server_path)
{
// upload a file
if (ftp_put($ftp, $ftp_server_path.$saved_to, $path, FTP_BINARY)) {
echo "successfully uploaded $ftp_server_path$saved_to\n";
} else {
echo "There was a problem while uploading $ftp_server_path$saved_to\n";
}
}
Then call once :
$ftp = $this->ftpConnnect($serv, $user, $pass);
for each images
if($this->uploadOnServer($path, $saved_to, $ftp, $ftp_server_path))
unlink($path);
And at the end :
ftp_close($ftp);
im trying to scale my Azure SQL DB with php. All the other sql statements works fine, but when im sending
ALTER DATABASE db1_abcd_efgh MODIFY (EDITION = 'Web', MAXSIZE=5GB);
i get an error like that
User must be in the master database.
My database URL is that
xaz25jze9d.database.windows.net
and the database is named linke that
db1_abcd_efgh
function skale_a_m(){
$host = "tcp:xaz25jze9d.database.windows.net,1433\sqlexpress";
$user = "db_user";
$pwd = "xxxxx?!";
$db = "master"; //I have tried out db1_abcd_efgh at this point
try {
$conn = new PDO("sqlsrv:Server= $host ; Database = $db ", $user, $pwd);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (Exception $e) {
}
$string = 'use master; ALTER DATABASE db1_a_m MODIFY (EDITION =\'Web\', MAXSIZE=5GB)';
$stmt = $conn->query($string);
}
Now i have modified my function linke this
function skale_a_m() {
$serverName = "tcp:yq6ipq11b4.database.windows.net,1433";
$userName = 'db_user#yq6ipq11b4';
$userPassword = 'xxxxx?!';
$connectionInfo = array("UID" => $userName, "PWD" => $userPassword, "MultipleActiveResultSets" => true);
$conn = sqlsrv_connect($serverName, $connectionInfo);
if ($conn === false) {
echo "Failed to connect...";
}
$string = "ALTER DATABASE master MODIFY (EDITION ='Web', MAXSIZE=5GB)";
$stmt = sqlsrv_query($conn, $string);
}
Now i get no errors but the Db did not scale?
According to ALTER DATABASE (Windows Azure SQL Database), the ALTER DATABASE statement has to be issued when connected to the master database.
With PDO, this can be achieved by a connection string such as:
"sqlsrv:server=tcp:{$server}.database.windows.net,1433; Database=master"
Sample code:
<?php
function scale_database($server, $username, $password, $database, $maxsize) {
try {
$conn = new PDO ("sqlsrv:server=tcp:{$server}.database.windows.net,1433; Database=master", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->setAttribute(constant('PDO::SQLSRV_ATTR_DIRECT_QUERY'), true);
$conn->exec("ALTER DATABASE {$database} MODIFY (MAXSIZE={$maxsize}GB)");
$conn = null;
}
catch (Exception $e) {
die(print_r($e));
}
}
scale_database("yourserver", "youruser", "yourpassword", "yourdatabase", "5");
?>
Note: It's not necessary to set the edition; it will be set according to the max size.
To test the sample code, configure it with your details (server name, login, password and database to be scaled) and execute it with PHP configured with the Microsoft Drivers 3.0 for PHP for SQL Server.
After that, refresh (Ctrl+F5) the Windows Azure Management Portal and you should see the new max size reflected on the Scale tab of the database.
You can also verify that it worked by using a tool to connect to the scaled database (not to the master database) and issuing this command:
SELECT CONVERT(BIGINT,DATABASEPROPERTYEX ('yourdatabase', 'MAXSIZEINBYTES'))/1024/1024/1024 AS 'MAXSIZE IN GB'
$string = 'use master; ALTER DATABASE db1_a_m MODIFY (EDITION =\'Web\', MAXSIZE=5GB)'
I'm pretty sure SQL Azure does not support switching Databases using the USE command.
Try connect directly to the master db in your connection, and remove the USE Master statement from the start of your query.
$host = "tcp:xaz25jze9d.database.windows.net,1433\sqlexpress";
That also looks wrong to me. You shouldn't have a named instance called SQLExpress at the end of your server connection afaik.
