I have a php file to fetch data from a server
When I try to execute it, I get a message saying:-
Warning: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 111 in /home/-/-/public_html/GetData.php on line 3
And line 3 is
$con = mysql_connect("cs.neiu.edu","myusername","mypassword");
Also I've tried by giving the hostname as localhost,but its not working.
You need to configure binding address bind-address in my.cnf and grand access to the database eg. GRANT ALL ON foo.* TO bar#'162.54.10.20' IDENTIFIED BY 'PASSWORD';
That error means connection refused. I am in the same class that you are and obviously I am using the same server, and I would guess that you are entering the wrong password. It may not be the same password that you connect to the server with if you changed your password from what was given in class. I use the following and it works fine....
<?php
$con = mysql_connect('localhost','username','password');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("databaseName", $con);
..
..
..
mysql_close($con);
?>
Actually i realized that my password was wrong.

In my script on de webserver I'm trying connect to mysql through the (good old) mysql_connect() to an ip (db server) in the same network.
MySQL keeps throwing me the error:
Access denied for user ''#'localhost' to database 'dbname'
This seems like the db is being searched on the localhost (webserver) instead the IP I've entered (db server).
I've checked the my.cnf and can't find a bind-address or whatever.
When I connect through mysqli_connect(), the connection can be made, so there shouldn't be a firewall issue I guess.
Reason I'm still using mysql_connect is because i'm transferring a big website to a new server, and there is no time to change the function through all the script.
Anybody familiar with this problem and got any suggestion? Thanks in advance!
Update: piece of code
$link = mysql_connect("12.34.56.78", "username", "password");
if (!$link) {
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db('dbname', $link);
if (!$db_selected) {
die ('Can\'t use dbname : ' . mysql_error());
}
Make sure you have "SQL safe mode" disabled in your php.ini file.
From the documentation of mysql_connect on the server parameter:
server
The MySQL server. It can also include a port number. e.g. "hostname:port" or a path to a local socket e.g. ":/path/to/socket" for the localhost.
If the PHP directive mysql.default_host is undefined (default), then the default value is 'localhost:3306'. In SQL safe mode, this parameter is ignored and value 'localhost:3306' is always used.
Similar filtering applies to the username and password parameters:
The username paramter defaults to the name of the user that owns the server process and password defaults to an empty string.
You can read more on SQL safe mode from here:
http://us1.php.net/manual/en/ini.core.php#ini.sql.safe-mode
Looks like the php is searching on the localhost but is using the username "". I think you have a problem with your user/pass combination and are also putting the ip address in the wrong place. Could you paste your code?
I have php script running on XAMPP on my local PC and I want to access some databse other than one on my localhost. Even if I call script with my own IP address I can't connect to the database.
PHP script looks like:
<?php
$host = $_GET['host'];
$username = $_GET['username'];
$pass = $_GET['pass'];
$database = $_GET['database'];
$con = mysql_connect($host,$username,$pass);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("performance_schema", $con);
$zavrsni = "zavrsni";
$result = mysql_query("SELECT `OBJECT_NAME`,`COUNT_INSERT`,`AVG_TIMER_INSERT`,`COUNT_UPDATE`,`AVG_TIMER_UPDATE`,`COUNT_DELETE`,`AVG_TIMER_DELETE` FROM `table_io_waits_summary_by_table` where `OBJECT_SCHEMA` =\"".$database."\"");
while($row = mysql_fetch_assoc($result))
{
$output[]=$row;
}
print(json_encode($output));
mysql_close($con);
?>
I call this script as:
http://zavrsni.noip.me/dohvat.php?username=root&pass=ficko1&database=zavrsni&host=zavrsni.noip.me
And then I get error:
Warning: mysql_connect(): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in C:\xampp\htdocs\dohvat.php on line 8
Could not connect: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
I know that this is not the most secure way of connecting the database, but I'm new to PHP so don't judge the terrible code.
Your database is not open for connections from outside.
Log in to the server on which the database resides, log in to your database as root and then enter:
USE zavrsni;
GRANT ALL PRIVILEGES ON * to root#% identified by 'ficko1';
or better
GRANT SELECT ON * to root#% identified by 'ficko1';
Please note that it global grants are highly unsure. Learn how to use the privilege system and later grant only those privileges which are actually needed.
If this still does not work, your mysql server is not permitting connections from outside. Have a look at http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
I've made mysql.php file which contain codes to connect to my database.
However, i'm getting this error message over and over again.
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061) in C:\CustomerData\webspaces\webspace_00290195\wwwroot\mysql.php on line 7

Unable to select database
I've checked if my username, host, database, and password were misspelled, but they were all correct.
I've looked around the internet, but couldn't seem to find the right one for my problem.
My mysql.php file contains:
<?php
// Mysql settings
$user = "example_example";
$password = "example";
$database = "example_example";
$host = "localhost";
mysql_connect($host,$user,$password);
mysql_select_db($database) or die( "Unable to select database");
?>
I've changed my user, password and host name to "example".
I just couldn't find the solution for myself, and I need your kind help.
Thank you in advance.
Please try to find out the error by using mysql_error() function as follows :
mysql_connect($host,$user,$password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());
and then try to find the exact reason for the failure.
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10061)
here a list of questions you have to do when this error appears:
1.- is mysql running on the server?
1.1.- is mysql running on default port or in a custom port?
1.2 - is mysql accepting connexions (from localhost, from an ip...?
1.3 - your firewall is blocking mysql?
2.- the database exists on the server?
3.- the user:password have access to that database?
3.1- the user:password can log in from localhost, from an ip... from any place that mysql
is accepting?
I think I don't forget anything
Please check first that your mysql server is running properly.
Mysql settings
$user = "example_example";
$password = "example";
$database = "example_example";
$host = "localhost";
$cn=mysql_connect($host,$user,$password);
mysql_select_db($database,$cn);
Please try this it may work
I am not expert of php but this code is working perfectly in my website
if you are getting any error after applying this code then please inform me i will rty to solve the problem.
Thanks
You should provide the connection that need to use from database whle selecting database. Also use single quote instead of double quotes.
<?php
// Mysql settings
$user = 'example_example';
$password = 'example';
$database = 'example_example';
$host = 'localhost';
$link = mysql_connect($host,$user,$password);
mysql_select_db($database,$link) or die( "Unable to select database");
?>
Reference
You have to get the database information first. You posted this problem when you try to connect to your database in your website hosting, right?
So, go to your hosting control panel to get the MySQL database (and take note of where the database is stored on! Sometimes some hosting providers don't use "localhost". Instead, some of them may use 'serverXX.yourhostingprovider.tld' where XX means the server ID), and then change the corresponding variables with the value you've obtained from the hosting control panel.
I'm start to learn mysql not so long time ago, and now i have problem, that i cant solve by myself.
I'm trying to connect to mysql server with php. My admin gaved me ip, port, login, pass and db name.
Php file looks like this:
$hostname = '192.168.1.20:1433';
$username = "h";
$password = "h";
$dbName = "mydb";
mysql_connect($hostname,$username,$password) OR DIE(mysql_error());
mysql_select_db($dbName) or die(mysql_error());
$query = "SELECT * FROM `insy` WHERE 1;";
$result=mysql_query($query) or die(mysql_error());
echo "works!";
mysql_close();
When i run page, its do nothing few minutes, than errors appears:

I tried to create ODBC Sql Server via Control Panel -> Administration - with same parameters - it works, connection is ok, and i ca see the Db's.
Tell me please, where is my fault?
I hope, i was clear.
Thanks for help.
you can try mysql_ping($conn) if your server connection lost.
http://php.net/manual/en/function.mysql-ping.php
I've just solved that problem.. the thing was when I did create a new user in MySql, after writing the user, the server ask you for where will be the "server" and you put localhost:8080.. ERROR! don't put the port!! just localhost.
And thats how I solved it..
I am trying to connect to the database that is hosted on my server through my local machine.
my server has cPanel 11, and it is a typical shared server, powered by CentOS, PHP and MySQL installed.
to be precise i am holding the reseller account in the same server. i want to access the database between different accounts or domains.
in MySQL connection String i tried defining the domain name, and it isn't working. here is what i tried.
<?php
$link = mysql_connect('mydomain.com', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>
this is giving the following error
Warning: mysql_connect() [function.mysql-connect]: [2002] A connection attempt failed because the connected party did not (trying to connect via tcp://bhatkalnews.com:3306) in C:\wamp\www\test\conn.php on line 4
Warning: mysql_connect() [function.mysql-connect]: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in C:\wamp\www\test\conn.php on line 4
Fatal error: Maximum execution time of 60 seconds exceeded in C:\wamp\www\test\conn.php on line 4
what do i have to define in connection string to make it work?
Firewall ?
try
telnet mydomain.com 3306
on the command line.
If that doesn't work, the connection is blocked by a firewall, most likely
Did you try adding the port explicitly:
mysql_connect('mydomain.com:3306', 'mysql_user', 'mysql_password');
or the port youre running on if not the default 3306. This of course assumes your server allows remote connections.
Also make sure the user in quest has access from the IP address youre connecting from. This isnt youre issue right now, but it may be the next question you have after you get the server to respond :-)

You need to add your IP address/range on Access Host list in Remote MySQL in cPanel.
