I am trying to connect to my data base and i get an error when I use 127.0.0.1 instead of localhost.
Warning: mysqli::mysqli(): (HY000/2002): 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.
If I use localhost instead of 127.0.0.1 it works fine. Anyone have any insight into this?
the code used to connect is
<?php
$db = new mysqli('127.0.0.1', 'root', '', 'dbname');
?>
Check the sql configurations. I'm going to list a few that should be checked that could cause this option. I do recommend sharing what version of php and sql you are using. Are you using LAMP? It is the same problem listed in the above comments. Newer versions of LAMP have changed the default to 127.0.0.1 for localhost. This is why it comes across as a different problem and you do need a different approach to fix it.
1) if my.cnf has a line reading skip-networking comment it out.
2) check the ect/hosts.allow file make sure there is a line that says
mysqld: ALL
3) check the ect/hosts.deny file and make sure there is only 1 line stating
ALL:ALL
Let us know if that fixed the problem.

I'm kind of new to programming and I'm only trying to connect to database using xampp but it gives me this error.
Warning: mysqli_connect(): (HY000/2002): No connection could be made
because the target machine actively refused it.
$conn = mysqli_connect('localhost', 'root', '', 'db');
I tried running the same code on a different PC and it works fine.
so i guess the problem lies within PC that I'm working on.
Any suggestions what to configure?
If you are sure that login and password are all correct, then check port number.
Default MySQL port is 3306. Maybe you've got different one on this machine.
Or, it is also possible, default port in PHP may be changed.
See XAMPP configuration to see MySQL port and add it to your server address.
PS: you may also see privileges for "localhost" connection. See 'user' table in 'mysql' database. As you have XAMPP installed, you should have phpmyadmin as well.
This problem I am having trouble with, I have been looking at it for a few hours now. So basically I am working on a registration form on my website, and while working on the php, I connected it to MySQL and Database with this line of code (which is the 6th line of code):
$mysqli = new mysqli('localhost:8080', 'root', 'mypass123', 'accounts');
I use Xampp on a Mac and when I try to register it works just not fully so, the problem is it shows this error:
Warning: mysqli::__construct(): (HY000/2002): Connection refused in /opt/lampp/htdocs/form.php on line 6
if this is not enough information, I am sorry but I am new.
PHP expects to use port 3306 for MySQL. So you need to open XAMPP, and change the XAMPP MySQL port to 3306, then restart the MySQL server.
Stop Xampp
Open xampp/mysql/bin/my.ini
Edit MySQL port to 3306
Restart Xampp
I'd say that it's already set to 3306 so just check what it's currently set to and update the setting in your PHP/phpMyAdmin to 3306 instead of 8080. 8080 is generally for the web server.
I've read many questions similar to this but none of the answers have been relevant to me. I'm trying to access a SQL server using PHP. Both the SQL server and PHP are running on my Windows 10 machine. Here is my PHP code (the username and password are arbitrary):
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password');
This causes the following error:
PHP Warning: mysqli_connect(): (HY000/2002): No connection could be made because the target machine actively refused it.
Here is my connection using MSSMS (which is successful):
EDIT:
I was able to solve my problem using this link: http://blog.citrix24.com/configure-sql-express-to-accept-remote-connections/
Using this link I enable SQL Browser, and set a static port to connect to SQL server with. However, I'm presented with a new error:
PHP Warning: mysqli_connect(): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): Error while reading greeting packet. PID=9920 in C:\HMUAPI\Index.php on line 7
PHP Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\HMUAPI\Index.php on line 7
My code has been changed to the following to cause this error: $connection = mysqli_connect('127.0.0.1:1434', 'hmuuser', 'password');
Add a database name
$connection = mysqli_connect('127.0.0.1', 'hmuuser', 'password','dbname');
Also here is suggest - Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
I guess the problem is, that you use MySQLi to connect to a MSSQL server.
You should use the correct MSSQL extension instead.
Microsoft published their SQL-Server for PHP driver on GitHub: https://github.com/Microsoft/msphpsql
Or you use the older extension which is documented in the PHP manual: http://de2.php.net/manual/en/book.mssql.php
And at least you can set up ODBC.
One of them should resolve your problem.
I have found this question here and around internet for few times, but none answered helped me.
So I have a local apache+php server and trying to connect to remote mysql database. But script returns me error and in error log i see:
PHP Warning: mysql_connect(): Premature end of data (mysqlnd_wireprotocol.c:553) in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
PHP Warning: mysql_connect(): OK packet 1 bytes shorter than expected in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
PHP Warning: mysql_connect(): mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file in D:\\_SERVER\\_WWW\\project\\api\\classes\\database.php on line 13
The script for connection (just the part connecting to server):
function db_connect(){
// Connect to the database server
$connection = mysql_connect("server.com:3306","username","password",true);
if (!$connection){
echo "Could not connect to the Database server, please check your settings";
die;
}
...
}
The trick with setting PASSWORD did not work for me, can someone please help me ?
Thank you
The remote needs to allow incoming MySQL connections from your server's IP address. This can be added within a the MySQL config file from the remote server.
For more information in how to edit the config file, here are detailed instructions.
http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
The firewall needs to port-forward to the server:port on the respective system,
which requires a static or dhcp address reservation for the mysql server machine
I get this everytime I use mysql_connect() no matter what database I choose:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'IP' (111) in filename.php on line 17
A MySQL error has occurred: Can't connect to MySQL server on 'IP' (111)
The exact same file works on my personal website fine. I have tried multiple databases hosted on different servers and it always gives that output.
The database itself is hosted on the same server, but using its full IP in mysql_connect(). Using localhost:port doesn't work either as it says:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in filename.php on line 17
A MySQL error has occurred: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
But using the IP should work as it has worked calling it via the same file hosted on other servers.
This is the code:
$connect = mysql_connect($db_url,$db_user,$db_pass); // connects
if ($connect == false) exit("A MySQL error has occurred: " . mysql_error());
Now since the file works on other servers i am guessing it is something to do with the server it is on and might need something changed. I don't personally have root access to the server (just my part of the shared host). Is there anything I can do i php, editing the php.ini file or something I should pass on to someone with root access?
Edit: Ok it turns out that the server doesn't have access to outside databases, so thats why the IP didn't work. Thanks for all your answers but we have decided simply to change hosting provider. We need to be able to access an outside database.
This is on a hosting service? Check their documentation, there will be something that tells you where to find mysql. It isn't necessarily localhost.
For example, on startlogic.com, you use: yourdomain.startlogicmysql.com
Can you connect using mysqladmin using the same host, username and password?
mysqladmin -h $db_url -u $db_user -p $db_pass
Replace $db_xxxx with real values.
If that works from the same host as your php script, then sudo to the apache User and try the same test. One of those must be failing.
EDIT: nevermind on sudo part, I noticed that you don't have root access.
Something else to try: Use '127.0.0.1' instead of 'localhost'. I have had issues before where mysql stupidly assumed it could silently change 'localhost:' to '/var/run/mysqld/mysqld.sock'.
Your wording is not very clear, I hope you are not thinking you can connect to the same mysql server from any old web server just because you know the IP address and port number. If the web host is at all competent, they have probably firewalled mysql so it is only accessible through their own web servers.
