I have created a PHP project and I am trying to host it online. To do so, I tried linking my database, which is in local phpmyadmin to heroku server. According to this post How to access remote server with local phpMyAdmin client?, I learned that phpmyadmin can be linked to online remote server by adding a piece of code at the end of config.inc.php file. But I do not know how to get information such as hostname, port and username from my herokuapp. Please help me out here. How to get information such as hostname, port and username from herokuapp?
Typically the hostname would be taken from InetAddress From the standard java library
(.getCanonicalHostName (java.net.InetAddress/getLocalHost))
Your web server will be assigned a dynamic port by Heroku but to ACCESS it, you will need to use the default port (80).
As for the user, you would have set that along with password.
Good luck.

I have got a cPanel hosting and I can create and log in to the phpmyadmin and change databases after I log in to the cPanel. What I need to do is log in to the same database even if my files are not on the same server, so I need to specify the exact database URL instead of "localhost". How do I get that URL?
The most secure way to access a remote database server is to setup SSH access on your database server and a SSH Tunnel on the web server that is hosting your files.
See: Connect to a MySQL server over SSH in PHP
This way you don't need to expose your database server to the internet, and instead can access it from the localhost of your web server.
If the database is exposed to the internet, you can assign a domain name to your database server and use that domain name, or subdomain, as the host and create a wildcard user like root#'%' but that is far less secure.
Hi I am trying to connect to my MySQL DB which is hosted by strato. On their site I can create a DB and I did. Now I am trying to connect to the database via NaviCat but I keep getting error 10060.
A screenshot of the strato website: screenshot strato webportal
A screenshot of my trying to connect to the database in NaviCat: screenshot NaviCat
And last but not least a screenshot of their website with an tutorial on how to connect to the DB: link to page
Maybe you're wondering why I don't contect the host, it takes ages for them to reply...
What am I doing wrong why cant I connect how can I fix it?
EDIT/UPDATE
I now setup a SSH tunnel but when I am trying to connect it still gives me this errorlost connection to mysql server at 'reading initial communication packet' system error 0
I am able to connect via PuTTy like shown in this link. And a found the port, hostname etc as you can see
But once I fill that into NaviCat, like this
and this
but still no luck :S now gettings this error:
If anyone can help me i would rlly appreciate it!
My guess is that Strato is blocking outside access to your database. Which is 100% good. Allowing internet access to a database is generally a bad idea.
You can connect to the database by SSH'ing to the server and then using mysql CLI. Instructions are provided in the link you shared in the SSH-access to the MySQL database section.
Using SSH you can also port tunnel to allow your remote connection with your client. This is a slightly more advanced technique where you link up a port on your local computer (localhost) to a port on the remote machine to which you are ssh'ing.
In PuTTy put in the server name like their instructions suggest:
Then go to SSH>>Tunnel in the left-hand menu. Fill out your Source Port (the port your local computer will be listening on) and your Destination (The server:port on the REMOTE computer that you are forwarding traffic to through the tunnel):
I'm using local port 66306, you may use whatever port you want as long as it isn't be used on your computer. Click "Add" and then Open the connection and put in your username/password when prompted. Refer to that Strato help doc if you get stuck.
NOW... in your mysql client (Navicat) you are going to connect your database. Because you have a tunnel open forwarding traffic from YOUR computer's 63306 port (or whatever port you chose) to the remote computers 3306 port you will specify in Navicat:
Connection Name: Whatever
Hostname/IpAddress: localhost
Port: 63306
Username: strato db username
Password: strato db password
Now it should connect. Strato sees your traffic as if it's coming from their server because of the tunnel and it will allow you through.
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 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!)
So I need to connect to a mssql server via Windows Authentication from a Unix server. Here are the obstacles:
The db admin created a service account but made it Windows-Auth only, meaning I can't pass the username and password directly to the server to connect.
The admin also added my host's server to the firewall so that it would only accept requests from my host machine.
My host server has mssql enabled via freetds/sybase-dblib, but has the default 'secure-connections: Off' still set.
I have a similar set up on my personal machine, but with secure-connections on, but I can't connect that way since I'm firewalled.
So I'm wondering if it's possible to set up a proxy of sorts on my host so that I can start the connection on my personal machine using my local freeTDS library, but have the request pass to the host which would (in my dream world) not require secure connections to be on but simply would pass the request along so that it came from my non-firewalled host but using the correct authentication method.
If anyone is not familiar with how Windows-Authentication works, it's a type of Kerberos authentication where the client machine makes the request to the remote server so that credentials are never actually sent (and thus can't be compromised by a man-in-the-middle). So I'm very doubtful that this can be done, since at some level my host machine has to do the actual work. But i thought I'd ask since I'm not totally clear on the deeper mechanics and because I really want to get this to happen.
I guess another way of looking at it is I want to use my host as a kind of VPN.
Also, I am working with my host admins to find a more long-term solution but I need to see the database as soon as possible so I can have something working when the problem gets fixed.
Why don't you try SSH port forwarding? Ie. you connect to your host server, and tell it to forward a local port to the sql server. Then you connect on your local machine using localhost:port and your connection will be tunneled over ssh through your host server.
If your local machine is a Windows machine then just download PuTTY and follow these instructions to set up port forwarding : http://www.cs.uu.nl/technical/services/ssh/putty/puttyfw.html.
The question is of course whether your Windows credentials will be passed, but in theory this should work :p.
