I am facing a little problem when i am trying to access to a remote server (no localhost) for my sql database. Normally, we need to pass throught a http authentication to access to the mysqladmin page, but i managed to go to the page with that line : http://user:password#site.net/mysqladm...
And it works.
I have also disabled the login confirmation's browser for the HTTP authentication.
Now, when i want to make it work on my php code, it is not working.
In localhost, it is working.
This is what I write on my code :
mysqli_connect('http://httpuser:httppassword#site.net/mysqladmin/index.php', 'root', 'password', 'db');
Do you have any issues for my problem ?
Regards,
mysqli_connect expects a host or IP address, to a MySQL database server, as first parameter.
You instead are passing a http link site.net/mysqladmin/index.php, which is just a administration backend that connects to the configured MySQL server. You need to determine the IP of the MySQL server which the backend is connecting to. Make sure that the firewall allows incoming connections on your configured port (default: 3306)
<?php
mysqli_connect('IP or host of the MySQL server', 'root', 'password', 'db');
?>

I am using the mysqli_connect($host, $user, $pass, $db) line to connect to another server through php. I am trying to write to a MySQL database.
I have used the server's IP [A.B.C.D] on the $host variable. However I cannot write to that database, and the script does not run completely.
I am using the root user and password to connect, and the user list in phpmyadmin shows that anyhost(%), 127.0.0.1 and localhost can connect with the root username (I think that's what it means). Anyway, as I am using root, I don't think this is a user privilege problem.
I have tried putting a # before 'bind-address=127.0.0.1'.
I have tried editing my.cnf according to suggestions from a lot of forums.
I have not installed firewall in any of the servers that I'm using, so unless Debian 7 64-bit comes with pre-installed firewall that blocks certain ports, I don't think that is the problem either.
Isn't there an easy way to establish connection between multiple servers? :-/
Your remote mysql server must accept remote connection from your IP address.
After you make this setup you can access remote mysql server like this:
mysqli_connect($remote_host, $remote_user, $pemote_pass, $remote_db);
I need to connect to a remote database server with PHP to query and return data.
So far, I have tried this:
$connection = mssql_connect('[redacted]:1433\SQLEXPRESS', '[redacted]', '[redacted]');
and
$connection = mssql_connect('[redacted]', '[redacted]', '[redacted]');
Both result in FALSE, but no error thrown. What am I missing? It doesn't even seem to attempt to connect (fails very quick).
Usually this isn't so much about the connection code as the setup of the external DB server. First try this:
$connection = mssql_connect('[redacted]\SQLEXPRESS', '[redacted]', '[redacted]');
But you are connecting to SQL Express which by default doensn't accept any incoming TCP/IP requests, so if that doesn't work out, you'll need to check the configuration (or if it's truly external, have the DBA check it) and make sure:
it's set up to accept TCP/IP requests,
that the firewall is allowing that IP and port through, and
that the specific IP address your request is coming in on is accepting requests
Good answer by AlexC, but what I wound up doing was converting the MSSQL database over to MySQL and performing the migration with the Migrate framework (Drupal).
I have website example.com, it contains a MySQL server. I have another example.org, both are different domains. I want to access the MySQL server on example.com from example.org. How would it be possible?
You will need to set the remote example.com when you call the database connection initialization function. For example:
mysqli_connect("example.com", 'username', 'password', 'database name');
But you will need to check whether example.com's MySQL server is set to accept connections from other hosts (see the bind-address directive in your my.cnf or my.ini), and that the username you connect with is set to be able to connect from external domains.
Consider the following Users page of phpMyAdmin:
It is clear that only user test has access from outside domains (% in the Host field). Not shown on the image, but user test has full privilege on the database called test. The other users are bound to the local domain, even though the server is set to accept connections from the outside, when authenticating, users are thrown a denial.
You can connect to remote MySQL server. Just have to make sure that the remote server is binding to public address.
Here's how: http://www.howtogeek.com/howto/mysql/switch-mysql-to-listen-on-tcp/
You can connect to any MySQL server wherever it is, as long as it's setup for remote connection.
Depending on your operating system and webserver of choice, the settings will be different, but a good place to start is by (if using linux) looking here:
/etc/mysql/my.cnf
In this file you will find:
bind-address: 127.0.0.1
You will change this to the IP address of the server and then restart the mysql daemon.
..and now you can connect remotely ;)
I am trying to connect my RDS Instance with my PHP connection file.
This is what I have in my file:
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'User Name');
define('DB_PASSWORD', 'Password');
define('DB_DATABASE', 'DATABASE');
$connection = mysql_connect(DB_SERVER, DB_USERNAME, DB_PASSWORD) or die(mysql_error());
$database = mysql_select_db(DB_DATABASE) or die(mysql_error());
I replaced localhost with my endpoint (rds thing) url, username and password with my RDS Instance user and pass and database name the one I've set when I created the instance. But it doesn't seem to work.
Is there anything else I have to do that I am not aware of or should it work?
RDS instances do not have a static IP address attached to them, you always use the endpoint for the host. For example:
database1.jlsdfjhgsdf.us-east-1.rds.amazonaws.com
If you are connecting to the instance with a username other than the root database account, you will need to grant the user privileges.
Check security group settings. If you are connecting from another EC2 instance on Amazon you will need to attach that security group. If you are trying to connect from outside AWS, you will need to whitelist the IP address you are accessing from.
Some ideas:
Try using the actual IP of the instance, then it should work.
Did you authorized access to your DB instance?

I was facing a similar issue whilst trying to connect an EC2 Apache server using PHP to the RDS MySQL instance.
Weirdly I could establish a connection via CLI - once in mysql running status will tell you which user youre logged in with, plus the port, server name etc.
Turned out some AMI images have SELinux enforcement - meaning the apache server cant send network requests as pointed out by this gentlemen (http://www.filonov.com/2009/08/07/sqlstatehy000-2003-cant-connect-to-mysql-server-on-xxx-xxx-xxx-xxx-13/)
Other points:
Make sure inbound ports are set for your RDS DB
In MySQL make sure the host is set to '%' as opposed to localhost
Always use the endpoint string to connect as the RDS IP changes
I was recently having a lot of trouble with this also but was able to fix it. I made sure my security groups (for the RDS and for EC2) were allowing each other. I was able to run my script from the terminal and connect to my database also from the terminal, but I couldn't get the script to run/connect to MySQL from a browser. It turns out I did not have mysql-server installed-- once I installed that and restarted httpd and mysqld it worked like a charm.
This article is what led me to installing mysql-server and the service starts/restarts. Hope it helps! -- http://www.rndmr.com/amazon-aws-ec2-easy-web-serverset-up-guide-with-a-mac-and-coda-2-256/
Just accepts all incoming connections.
I also had the connection problem between the ec2 (apache + php server) and the RDS (Mysql server) when following the tutorial at http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Tutorials.WebServerDB.CreateDBInstance.html.
I solved it by using the double quote when specifying the connection value while the guideline is using single quote.
define('DB_SERVER', "localhost");
define('DB_USERNAME', "User Name");
define('DB_PASSWORD', "Password");
define('DB_DATABASE', "DATABASE");
I was trying to connect to my DB instance using node-mysql. I found that I the endpoint that RDS provided me with did a DNS lookup. Followed that up and changed the URL to that one. I was only able to connect with mysql via command line until then. When I changed it to the resulting endpoint after the lookup, node-mysql was finally able to connect.
Ok, If you can answer this question, you deserve the nobel peace prize. Anyways, here's the situation.
I'm using Slicehost dot net, and I have 2 slices (two different IPs). One slice is my mail server and the other is my normal website. I'm running Ubuntu (8.04 or 8.10, something like that, it shouldn't matter). What I'm trying to do is access the MySQL database on the Mail server from the other slice. I'm trying to do that with PHP. I really appreciate any help.
mysql_connect()
$resource = mysql_connect('other-server-address.com', 'username', 'password');
The first parameter is the mysql server address.
Server Param
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.
Unless I'm misunderstanding... this setup is pretty common. Any trouble you're having might be related to the following:
Firewall settings
Grant access to the mysql user to connect from the other host
my.ini settings not allowing outside connections

Assuming your mail server is at IP 192.168.1.20 and web server is 192.168.1.30
First of all you need to allow the web server to access the mysql database on your Mail server .
On 192.168.1.20 you run the mysql command and grant access on the database needed to your web server
mysql> grant all on mydb.* to 'someuser'#'192.168.1.30' identified by 'secretpass;
Your PHP code connects to that database with something like:
$conn = mysql_connect('192.168.1.20', 'someuser', 'secretpass');
mysql_connect() returns a link identifier if the connection is successful. Also you have to do is keep the references to both links.
When you want to use which ever link, simply include the link as an argument.
$link1 = mysql_connect($host1, $username1, $password1);
$link2 = mysql_connect($host2, $username2, $password2);
$r = mysql_query(QUERY, $link1);
Simple as that.
