there's this server:
http://phpmyadmin.pvdata.fr/index.php ,
I can connect to it knowing the username and password and Server Choice.
Once I connect to it, it shows under MySql the following information: (I'm Translating from French)
Server: sql6 (sql6 via TCP/IP)
Server Version: 5.0.92-87
Protocol Version: 10
Username: pvdata#10.5.1.3
Character for MySql: UTF-8 Unicode (utf8)
So I tried using the following code in order to connect to the Database:
<?php
// Create connection
$username = "pvdata";
$password = "xxxxxxxx";
$hostname = "10.5.1.3";
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
?>
But it didn't work, it's saying: "A connection attempt failed because the connected party did not properly respond after a period of time".
What am I doing wrong?
Go to your phpMyAdmin installation and look for the file config.inc.php. Open that file, and check which hostname / ip is being used for SQL6. That is the IP you should use for your mysql_connect()
This is most likely a firewall issue. Most 3rd party hosts don't allow you to access MySQL from 'the outside'.
You can do this if you manage the MySQL server yourself or if you have a host that doesn't deny you to access the database from another machine, but in regular web hosting, this is not common.
You need to search, google helps a lot, also you need to connect to an ip/domain and port of your MySQL server.
For this, you need to know what is the port of your mysql server.
Look this answer from link
<?php
mysql_connect("mysite.com:3306", "admin", "1admin") or die(mysql_error());
echo "Connected to MySQL<br />";
?>
to check if you have coneccion, try in console:
shell> mysql --host=remote.example.com --port=3306 //3306 is the
defaul port for MySQL

I am attempting to connect to a remote MySQL server from my local machine virtualhost using the following code:
$conn = mysql_connect("$dbhost", "$dbuser", "$dbpass") or die(mysql_error());
mysql_select_db($dbname, $conn) or die(mysql_error());
My problem is that I am unable to connect locally, receiving the error:
Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)
This is not the case when I upload the same PHP file to the server. I am able to query the database with no problems at all.
I am unable to connect via command line either, but I can access cPanel which rules out the chance of my IP being banned accidentally.
My local server is running PHP 5.2.9, the remote server 5.2.12
firewall of the server must be set-up to enable incomming connections on port 3306
you must have a user in MySQL who is allowed to connect from % (any host) (see manual for details)
The current problem is the first one, but right after you resolve it you will likely get the second one.
It is very easy to connect remote MySQL Server Using PHP, what you have to do is:
Create a MySQL User in remote server.
Give Full privilege to the User.
Connect to the Server using PHP Code (Sample Given Below)
$link = mysql_connect('your_my_sql_servername or IP Address', 'new_user_which_u_created', 'password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_select_db('sandsbtob',$link) or die ("could not open db".mysql_error());
// we connect to localhost at port 3306
I just solved this kind of a problem.
What I've learned is:
you'll have to edit the my.cnf and set the bind-address = your.mysql.server.address under [mysqld]
comment out skip-networking field
restart mysqld
check if it's running
mysql -u root -h your.mysql.server.address –p
create a user (usr or anything) with % as domain and grant her access to the database in question.
mysql> CREATE USER 'usr'#'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON testDb.* TO 'monty'#'%' WITH GRANT OPTION;
open firewall for port 3306 (you can use iptables. make sure to open port for eithe reveryone, or if you're in tight securety, then only allow the client address)
restart firewall/iptables
you should be able to now connect mysql server form your client server php script.
This maybe not the answer to poster's question.But this may helpful to people whose face same situation with me:
The client have two network cards,a wireless one and a normal one.
The ping to server can be succeed.However telnet serverAddress 3306 would fail.
And would complain
Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)
when try to connect to server.So I forbidden the normal network adapters.
And tried telnet serverAddress 3306 it works.And then it work when connect to MySQL server.
I try to connect my android application using JSON Parser to the web hosting. But whenever I try to connect (even just open using url in the browser) I will get the error message.
<?php
$dbHost = 'http://sql4.000webhost.com/localhost';
$dbUser = 'a6410240_cbetTD';
$dbPass = 'xxxxxx';
$dbName = 'a6410240_cbetTD';
$conn = mysql_connect ($dbHost, $dbUser, $dbPass) or die ('MySQL connect failed. ' . mysql_error());
mysql_select_db($dbName,$conn);
?>
This is my database.php file. The full error message is
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'http' (4) in /home/a6410240/public_html/database.php on line 8.
I have tried change the $conn but still it didn't worked for me.
Thanks
If your database and application is on same server then use "locahost" in $dbhost.
And if your database and application is on different servers then you need to use IP address or hostname in $dbhost and the database user should be added on database server provided with required privileges.
The problem you are having was already mentioned in one of the comments, this one to be precise.
For your solution to work, all you need to do is omit the part http:// at the beginning and probably /localhost at the end.
The host is only the domain you are referring to. In this case sql4.000webhost.com. With /localhost you tried to already connect to a database, although your configured database is supposed to be a6410240_cbetTD.
MySQL use TCP port 3306 by default
($dbport) and hostname or IP address ($dbhost). For LAMP (Linux-Apache-MySQL-php) you can find a lot of tutorials.
Usually MySQL server listens internal port (which can't be reached via Internet) for security purposes.
If you familiar with docker, you can simply download examples of LAMP solutions from hub.docker.com.
I was just wondering if it was possible for certain databases to block SQL accesses through mysql_connect. I recently downloaded XAmpp and created a SQL database using my own computer as a local host and wrote a PHP file that accessed that database.
However, when I tried to change the username and host settings so that Xampp would run the PHP files that would then connect to the external SQL database of a free hosting site that I'm trying to use (biz.co.nf), I got the following error message:
Warning: mysql_connect(): Connection refused in /Applications/XAMPP/xamppfiles/htdocs/...
Right now I'm thinking either:
My login credentials to that database are incorrect, or
Somehow the host blocks SQL accesses from external users, but if I were to load my php code into the server using FileZilla, it should work okay?
Please let me know if this is the case.
I'm also fairly certain I have the right login credentials.
Here's what I have:
$host = "fdb13.biz.nf";
$username = "1764941_login";
$password = ________;
$db_name = "1764941_Login";!
$tbl_name = "Members";
//Connect to server
mysql_connect($host, $username, $password)or die("Cannot Connect!");
mysql_select_db($db_name)or die("Cannot select Database");
with my server settings according to my website...
Of course, I omitted my password.
Connections are refused from remote locations to MySQL for security reasons. You can add your IP Address to enable MySQL to listen from your database by following the instructions in this link - Cyberciti biz tips on enabling remote access to mysql database server In your case, add the IP address of the location where your PHP script.
I would also say that
mysql_connect
is deprecated in PHP. Use mysqli instead. Check the comments in the link - PHP original MySQL API
I want to ask about how to connect my localhost application (C:xampp/htdocs/myproject) to database at my server host (www.someweb.somedomain)?
Am I possible to do that? If it is, how to connect it at my php config? Right now my config (server.php) is:
<?php
$host = "my web IP public:3306";
$user = "root";
$pass = "";
$db = "dispatcherDB";
$conn = mysql_connect($host, $user, $pass) or die ("Cant connect to mySQL");
mysql_select_db($db);
?>
what I got:
Warning: mysql_connect(): No connection could be made because the target machine actively refused it. in C:\xampp\htdocs\XMS\server.php on line 7
So, what must I filled for $host? I'm trying using website IP, it still can't connect. Maybe there's someone here have experience at this problem?
Sorry for my bad English
If you have cPanel access to the remote server then you need to mention that from which ip addresses it should allow access to MySQL..
In cPanel you will get Remote MySQL under heading Databases:
Clicking Remote MySQL will give you the option to add hosts from where you want to allow connections to your MySQL server:
Also, you can check localhost without specifying port number as value of $host..
Probably Mysql server is not allowed root access from remote servers.
