I am trying to connect to a remote mySQL server from a Godaddy hosting account.
$con = mysqli_connect("xx.xx.xx.xx","username","pass","db_name",'3306');
I am using the above code, but keep getting the following error back:
Can't connect to MySQL server on 'xx.xx.xx.xx' (110)
From the error it seems that it's trying to connect on port 110, even though I have specified 3306 as the port in the PHP call.
If the script resides on the same machine as the mysql server then change the ip address to 'localhost' and since you're using the default port you can drop that as well.
If your script is attempting to connect to a machine outside of your localhost, you may need to allow the ip either via iptables or the remote mysql host within cpanel.

I'm trying to connect to a remote Firebird database "test" (alias already added). It is not an embedded server, and is installed on VM with IP 192.168.1.147.
Here is my connection string:
User=sysdba;Password=masterkey;Database=test;DataSource=192.168.1.147
However I got an error:
FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Unable to complete network request to host "192.168.1.147". ---> Unable to complete network request to host "192.168.1.147".
I've done some research on that but haven't got a clue yet. Some help needed. Thanks
My IP address is 192.168.2.108, and I can ping that server IP successfully
Make sure that
Firebird is running
Firebird is listening on port 3050 on the specified IP (or on 0.0.0.0)
Your firewall allows access to port 3050
You're using the correct host name
For Linux, the Firebird port is closed by default. You need to modify RemoteBindAddress in /etc/firebird/2.5/firebird.conf from
RemoteBindAddress = localhost
to
RemoteBindAddress =
and restart service.
Make sure you have excluded tcp port 3050 in VMs' firewall.
Ok. I think your connection to firebird is faililing because the firebird client looks up the network service file by name and does not find gds_db in the services file.
If your connection string refers to the host by using IP, the Client might fail to identify it because it gethostbyname() and not by IP
Manually include this in the file and you should be fine.

I have a MySQL database, hosted by me on a Windows server, and I would like to query it from a remote webserver. When I try to connect to the MySQL database using PHP (I know, I should be using mysqli):
$connection = #mysql_connect("203.0.113.0:3306", "username", "password");
With or without specifying the port, after a long time of loading, I get this error with an errorno of 2003:
Can't connect to MySQL server on '203.0.113.0' (4)
Here is what I get when I run netstat -n in command prompt on the server that is hosting the MySQL server: http://pastebin.com/pbRJNqCZ. It filled up the screen so I couldn't copy everything, but I know that everything else was (I saw a couple ports with a value of 3306, which is the MySQL port):
TCP 127.0.0.1:port 127.0.0.1:port ESTABLISHED
When I run netstat -a | find "LISTENING" I get: http://pastebin.com/Lqj2BrQK
Here's what I know so far:
It isn't an error with the MySQL server not being up, because I can connect to it locally.
It isn't an error with the webserver not being able to connect to MySQL databases, because I can connect to other databases
It isn't an authentication error (The username and password are correct, and the remote server has permission)
It isn't a port forwarding error, because the port 3306 is fowarded on both TCP & UDP.
It isn't an error with being able to connect to the machine the server is hosted on, because I can ping it fine.
The server isn't only listening on the localhost interface. skip-networking and bind-address are commented out in my my.cnf file.
How could I edit my connection code, or edit my MySQL server to fix this error?
Summarizing our discussion/chat:
Bind the network address 0.0.0.0 in my.cnf: bind-address = 0.0.0.0 and ensure skip-networking is commented out or not present.
Check netstat -a | find "LISTENING"
According to your pastebin there is a service listening on 3306. Test if the port is reachable on the NIC address from the server itself. This way an external firewall does not take effect. A simple test is to try a telnet connection to that port. More detailed information can be catched by the tool nmap. Nmap has displayed the mysql port as filtered. This adverts to a problem with a local packet filter, in this case the Windows firewall.
Ensure the Windows firewall is configured to allow public access to TCP port 3306 from all or a specific machine. Setup a rule in public profile or, if both servers are controled by the same domain controller, in domain profile. When the access from local machine is successful try the same from the remote web server.
If you fail to properly configure remote access to MySql port, consider to establish a SSH tunnel between the two machines. Once established you can access to MySql as if it were on the local machine. The port is then forwarded via the tunnel and on the database server side you can access the service on localhost loopback IP.
I'm trying to connect to a remote database on a server which is accessed through cPanel.
I created a user name and associated it with a database. I'm using:
I'm confused on the host name to use. I tried using the Main Domain name in the left menu panel in cPanel with the port number 3306 but it wouldn't work. I used the shared IP as well with the port number that that wouldn't work as well. I have added my local machine IP to the remote databases page in the cPanel as was told in a post but finally I'm not able to connect to the database.
On echoing the mysql_error(), I get:
Can't connect to MySQL server on 'host_name' (4)
Any help would be great!
your hosting site will specify which name should be used for the host
in hostinghood.com they says that to use localhost itself as host name
so check what your hosting site says about it
So I have a PHP file hosted on Namecheap server.
$db=mysql_connect ("ipaddress", "user", "pass") or die ('I cannot connect to the database because: ' . mysql_error());
and it gives this error:
I cannot connect to the database because: Can't connect to MySQL server on 'ipaddress' (110)
I CAN connect to this DB using mysql workbench outside of the network just fine.
I have experienced this issue. What I did was use the internet address instead of your public IP/DNS.
Since, I'm using Linux I do ifconfig and you will see inet addr: xxx.xxx.xxx.xxx and use that IP as your host instead of the public IP/DNS. On Windows, Simply use your local IP address.
That's it!
If you are using MySQL for your database solution (which seems odd due to the usage of IIS on a Windows Server operating system)
Try running (As Root):
GRANT ALL ON Database.* TO Username#'IPAddress' IDENTIFIED BY 'PASSWORD';
Where the second is the permissions that you are granting on, this is a place holder for all
This will allow a connection from the IP you specify
also A problem is with connecting to your MySQL engine from inside your network, you will naturally connect from an internal IPV4 Address (192.168.0.x for example) this does not require portforwarding. BUT if you are using:
mysql_connect('WANIP', 'User', 'password'); you will have to forward port 3306 to your server. http://www.portforward.com for assistance.

I have faced this issue when installing opencart on my server. When i was using Windows server it requires IP address of website/domain. Now when shifted to linux hosting, linux hosting accpted as localhost And done. I could install opencart
website A: hosted on some free web host.
website B: my server
I want to connect from website B-(client) to mysql server of website A-(my server).
I've granted remote permission on mysql user with %.
But connection doesn't work. I've tried to run php script (mysql_connect) on different free web hosts.
000webhost.com : Can't connect to MySQL server on 'My SERVER IP' (4)
biz.nf : Lost connection to MySQL server during query
same script different mysql errors.
this php script run smoothly on my online SERVER, and also on localhost setup (connecting remotely to SERVER).
Is something else I've to configure on my SERVER?
I know that free web hosts doesn't allow remote mysql connection but in my situation I'm trying to connect with my own mysql server.
Does "remote mysql access" means both in and out connetion?
I've search a lot, something to do with ip-binding or port? I dont know where is actual problem?
Kindly help me out.
Tell mysql that it should listen on a fixed IP address, not 127.0.0.1 or localhost.
open file /etc/mysql/my.cnf (or /etc/my.cnf):
before
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
after
# INSERT YOUR IP Address here
bind-address = 192.168.45.1
#bind-address=127.0.0.1
Then restart your mysql server. HTH
Does your remote website's firewall allow external connections to the MySQL Port 3306?
