I'm doing this for a couple of years now but I haven't faced anything like this. I'm renting a webserver which has MySQL storage. For security reasons the hosting company refused to give me a host name to connect to the MySQL server from a php script. The reason was that there is an IP filter on he server and one can only connect to it with a whitelisted ip. Is there any solution for this situation like a server sided proxy? Also I do have access to the MySQL server via phpMyadmin.
I did some research and I've found that Navicat has proxy support. Altough it's not free.
Based on your description, it sounds like you have a server with MySQL, PHP and phpMyAdmin all running on the same server. If that's the case then typically the hostname for MySQL will be "localhost", possibly with a port or other code added. It is quite common for web hosting companies to not allow remote MySQL access, though the good ones will have it off by default and let you turn it on either for specific IPs (best) or for "everywhere".
When you are logged into phpMyAdmin, take a look at the very top of the main window and you should see something like Server: localhost or Server: www.example.com:3306 - that is your hostname for any MySQL access, provided the PHP code is running on the same server as phpMyAdmin.
If you actually need to run a program on a different server and access that MySQL database then you are probably out of luck.

apparently my hosting provider does not support Remote MySQL Usage as it says in its Knowledge Base even though i bought a premium package
remote MySQL connections are disabled for security and performance reasons. You can only connect to MySQL from your PHP scripts hosted on our servers.
is there any way i can make an API so that i can connect to my MySQL Remotely ?. i need to use the Database in my Host Account as a source of information for my Android Application. thanks
You should look into using something like a HTTP Tunnel.
This post outlines a method of doing this for Android.
Basically you connect through this tunnel which is placed on your server, and can the communicate with the server as if you were localhost.
SSH is also another option, although you'll need remote SSH access enabled by your host. That's normally something you'll have to specifically request for them to enable.
You would then create an SSH tunnel using a technique like this and then use that as your connection for your database. Once you've initiated the connection you would then query it as normal.
There are possibilities here.
Your hosting provider may have allowed access of the database only
on certain IP(s) on certain PORTS. In this case, you cannot access
the database even if you write API's because the connection is not
open to the IP/PORT through which you are accessing through.
The database admin can also block access to certain table(s) or
database(s) for certain users.
I have a WordPress website, which is not done by me, all I need to do is connect to its database remotely and query some results from its database. The point is that I don't know anything about WordPress, and I saw that the database information are written inside the wp-config.php file, when I opened it, there was the username and password, but the host name was this:
define('DB_HOST', 'localhost');
Which seems a bit curious to me. The website uses cPanel X from GoDaddy, and when I logged in there and opened phpMyAdmin, it had these information under database server part:
Server: Localhost via UNIX socket
So, I really don't know how to remotely connect to the database and query things, because host name says localhost. I'm used to ASP.NET MVC, and where I specify the host name to be the actual server ip or hostname of the database server. Any idea how should I proceed?
This is probably a better question for superuser as it's technically a hosting related question. That being said, you would need to contact GoDaddy and find out if they even allow remote MySQL connections on their servers. Most hosting companies disable external connections to the MySQL server on port 3306, but if you portscan your domain name/IP and see 3306 open then you can probably remote connect to it. Just use the domain name/IP of your site as the host, and pull the user/pass/db name from the config file.
You can do this by using command line.
GRANT ALL ON wpdb.* TO wpuser#`192.168.2.25` IDENTIFIED BY `Pa55w0rd!`;

I know this is not a particular php question, but it is to do with accesing php by using mysql when the file is not hosted on the same domain.
For example, im using hyperedit, the php coding tool that allows you to display the results of php in realtime as you code.
However when i try and type my mysql code in, that i know works(i tested it using my servers built in php/html etc creator) i get a error:
Connection refused (trying to connect via tcp://myservername.servername.com
Its definitely not my code, i think instead it is something to do with the fact that the file is not being hosted on the server? I have only tried it in hyperedit but i think the same would occur in other programs too.
I know its not specifically php or coding related, but i thought this is the best place to ask!
If anyone could help me it would be great!
Thanks very much!
This is because your local development machine does not have access to the mysql server in question.
If this is a shared account, you may be able to grant access to your remote machine's IP/hostname through cPanel. If you have direct access to the remote box through the cli, you can do it via a sql GRANT command, like so:
GRANT SELECT ON mydb.* TO myusername#'my_IP' IDENTIFIED BY 'mypassword';
Otherwise, it may be locked down in a shared environment where only machines on the local subnet can access the mysql server (cough, GoDady, cough).
So there's no real answer. Either you have the privileges to give your remote machine access, or you don't. If you don't, consider using another host that does allow you to do what you need.
I have set up my wordpress site on my local machine and I would like it to talk to the live mysql database on the server. I accessed the wp-config.php file on my machine and changed the hostname to use the ip address instead of localhost, but it will not work.
What do I need to do?
It could be that your remote database is configured to accept connections only from localhost for security reasons. Most web providers set it up that way. In that case, you have no chance of making this work.
Anyway, even if you would get it to work, you will encounter two problems: It will be awfully slow, and the HTML served by the remote database will contain references to server URLs (as opposed to local ones).
If you need more detailed information, you will need to post any error messages you get from mySQL.
Alternatively, you can try running the mysql command-line utility to connect.
mysql -u username -h server -p wordpress_database
Make sure that works first before attempting to get Wordpress to connect.
My guess is you won't be able to connect due to firewall issues. MySql uses port 3306 by default, so if the server's firewall doesn't allow connections through that port, you'll either have to change the port mysql is using (probably a bad idea if other apps expect to see MySql on that port) or get that port opened on the server (make sure you only open it for local IPs, so someone else can't get to your MySql instance!)
I'm working with my University's Systems Administrators to get a LAMP stack setup for me. I'll need to access this server from several websites that I'm working on and I'm having some issues.
So to keep thing's clear:
LAMP Server URL = https://mysqlserver.edu
School URL = https://schoolsite.edu
When I run mysql_connect() on the LAMP Server it connects fine:
mysql_connect('localhost', 'user', 'password'); Works great!
However, when I run mysql_connect() on the School URL I can't connect:
mysql_connect('mysqlserver.edu', 'user', 'password');
Warning: mysql_connect(): Unknown MySQL server host 'mysqlserver.edu' (1) in /home/content/x/x/x/xxx/html/testconnect.php on line 3
Unknown MySQL server host 'mysqlserver.edu' (1)
What do I need to ask the System Administrator to do in order to give my PHP scripts on external sites access to the MySQL server?
Does the SSL complicate issues?
I appreciate any insight you might be able to provide.
Unknown MySQL server host probably means that your machine cannot resolve to hostname mysqlserver.edu, have you tried connecting via IP address?
After you make sure you are resolving the name, you have to overcome three further barriers:
firewalls as others have shown,
MySQL server configuration which has to allow remote connections and
a user able to connect remotely has to be setup.
MySQL user depends on the computer it is access from. 'root#localhost' is not the same root as 'root#192.168.0.156'. So you have to add the user from the computer you are going to access from. So let say the computer where php script is served is '192.168.156' you need to add a user 'user#192.168.0.156' to the MySQL server and don't forget to set the privilege for that user to access to the database needed.
Hope this helps
It's rare to make a MySQL connection over a public WAN. It's common to take a LAN hop or two but you usually can't cross a firewall for security reasons. That is, incoming TCP connections to port 3306 are being blocked by the firewall or gateway onto the local LAN where mysqlserver.edu is.
The canonical test for this is:
$ telnet mysqlserver.edu 3306
I can predict that this will not work. ("Work" means that it reports "Connected to..." and outputs some gibberish.) You have several choices:
run the database locally, or at least nearby. I mean, it's not a LAMP stack unless it has MySQL. :-) This is what approximately everyone does.
use a tunnel / VPN solution of some kind to get through the firewall and to port 3306
open up 3306 on the firewall. You probably will not get cooperation on this.
Is "skip-name-resolve" option enabled in your my.cnf?
