Trying to set up and host a db on Bluehost but having issues when testing it locally. Setting connection string as $link = mysqli_connect("localhost", "username", "password", "dbname")
`
but I keep getting "No connection could be made because the target machine actively refused it".
I should note that I'm setting the database as a remote connection.
It seems permission is granted, try to grant the permission first. Here "%" mean Db can accept the connection from any IP, if you want to make DB can accept the connection from specific hostname for IP then instead of "%" use the hostname or IP.
GRANT ALL PRIVILEGES ON dbname.* TO 'username'#'%';

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 have windows 7 system and installed xampp in it.
I can access phpmyadmin using http://ipaddress:8080/phpmyadmin from remote system.
But if i try to access it from php it will give me error :
Warning: mysqli::mysqli(): (HY000/2013): Lost connection to MySQL server at 'reading initial communication packet', system error: 20
My php code is
define("HOST", "X.X.X.X");
define("PORT", "port"); // The host you want to connect to.
define("USER", "user"); // The database username.
define("PASSWORD", "password"); // The database password.
define("DATABASE", "DBname"); // The database name.
$mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE, PORT);
// or without port $mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE);
if ($mysqli->connect_errno) {
printf("Connect failed: %s\n", $mysqli->connect_error);
exit();
}
I have also tried firewall turning off, and also allow port 3306 to firewall, but no luck. Granted all PRIVILEGES to this user with host any (%).
I have also tried using bind_address = 0.0.0.0, commenting that line, and also bind_address = X.X.X.X (my IP).
Also tried changing socket type from "MySQL" to "TCP/IP". skip-networking line is also commented default.
I have tried to access from command prompt using:
mysql -h X.X.X.X -u root -p
This will give error:
Warning: mysqli::mysqli(): (HY000/2003): Can't connect to MySQL server on 'X.X.X.X' (110).
Using localhost in same system in connection string it works fine.
Where i am wrong i can't figure out. I have searched and tried all possible solutions.
Thanks for help.
Note: rather than above, right now my conf file is same as at time of installation. Please don't mark this question as duplicate.
Edit: #Jay Blanchard, As i have referred that solution also, in that case system error : 0, in my case system error : 20. Thanks for help.
My research says that error 20 on sql means it is being ran from a user that is not granted system admin rights. This limits the abilities of the sql server. The way to fix this is make sure the user the server is being ran from has admin rights. This can be done in the control panel from a windows user that has admin rights.
I am trying to connect to a MySql server (not localhost) from my computer using the code below. It is giving this error:
Warning: mysql_connect() [function.mysql-connect]: [2002] Connection refused (trying to connect via tcp://10.6.3.6:3306) in on line 7
I wonder if we can use the http protocol to connect instead of tcp that is being used by default? I searched quite a bit on how to change the protocol, but most of the answers were describing how to connect to localhost, and not much about how to connect to another server. Please help.
PS: I am able to connect to the server by going to http://10.6.3.6/phpmyadmin/...). So I am sure the server is up.
My Code
<?php
$db_hostname = '10.6.3.6';
$db_database = 'db_user11';
$db_username = 'db_user11';
$db_password = '########';
$db_server = mysql_connect($db_hostname, $db_username, $db_password);
if (!$db_server) die("Unable to connect to MySQL: " . mysql_error());
mysql_select_db($db_database, $db_server)
or die("Unable to select database: " . mysql_error());
?>
You can't. HTTP is not a protocol suitable for this.
You are talking about 2 processes communicating here (MySQL Server and your app) and they either do it via shared memory, pipes or sockets. Those are the 3 ways that processes communicate with each other.
First of all, HTTP is layered on top of TCP/IP.
In order to connect to something via HTTP, it needs to run an HTTP server. MySQL does not run an HTTP server and there's no current/realistic/supported way to tunnel an SQL connection through HTTP. Even if there was, HTTP is not exactly the best protocol for this.
In short: no. You're trying to solve the wrong problem. You need to configure your MySQL server to allow connections from other machines over the network, give the user you're trying to connect with appropriate permissions to connect from other machines and make sure the MySQL server is reachable from other machines.
Just because the phpmyadmin is hosted on that server, does not neccesarily mean that the database server is in the same IP address. Please ask the domain administrator to give you the details of database server.
Maybe just check and make sure the mysql user account you are connecting with has proper permissions set for remote access.
In other words, this may be obvious but make sure the user has valid remote credentials.
On the command-line ( if you can relate to this ) , one can do this in mysql to add a user allowed to connect from remote connexion:
mysql> CREATE USER 'monty'#'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'#'%'
-> WITH GRANT OPTION;
This would create a user, monty with password some_pass, with FULL privileges on all databases, all tables from anywhere. The % is the key here, and is needed for remote access.
MySQL users created through gui tools often set the host to 'localhost' and this would not allow a remote connexion.
Hope this helps. Good-luck.

I'm using PHP with MySQL database. The PCs are having a network to each other. My problem is I want to connect to the MySQL database on another computer. I want to store data on that MySQL database from another computer. How could i possibly do on this? Thanks so much for any suggestions.
The MySQL server must be configured to accept connections externally, and its firewall must be configured to allow incoming connections on that port (TCP port 3306). This may or may not already be set up.
You must also account for this in the MySQL permissions as follows.
Often, when setting up your MySQL permissions, you'll set user access rights only for #'localhost'. You'll need to make sure that both the user account and its granted permissions are set for the appropriate hostname or IP address you will be connection from. For example, you could create a new authorised user with:
GRANT ALL PRIVILEGES ON somedatabase.* TO someuser#'somehostname' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
You have to do all of this before you can connect to that server remotely with PHP, using something like this:
mysql_connect('mysqlservername', 'someuser', 'password');
Point mysql_connect() to use the other computer's name / IP address:
$server = '192.168.0.3';
$user = "foo";
$password = "bar";
$conn = mysql_connect($server, $user, $password);
You'll need to make sure the DB in the other PC has enough rights to connect from a different host - i.e. your computer.
Set up MySQL as normal on that computer. Then, simply:
<?php mysql_connect('IP of 2nd computer', 'username', 'password'); ?>
