This may sound like a dumb question, but I'm new to this. I'm setting up a website, and I want it to be able to have access to a MySQL database. I've recently downloaded MySQL 5.6 and have used the Workbench and Command Line Client to learn to make databases.
But all of this seems to be running of localhost, so I think it's just running off my computer, and when I shut it down the website won't be able to access it.
Is this correct?
Do I have to run it somewhere else to keep it accessible to my website 24/7, even when my computer is off?
Well, yes it is running of localhost unless you deployed it on another server. Yes, you have to run it somewhere else if you want it to run when your PC is turned off. In fact, if you want to make a website and use a database for it then there are many services out there that provide free hosting and come with a MySQL database.
An example would be freehosting.com without intending to do advertisement. A quick research would show you many alternatives.
Currently its running on your localhost or your computer. To make accessible website 24/7 to need to using hosting services like, Godday, Hostgator, bluehost or there hosting.
You can purchage you domain at very low cost with full services on Godday with full support.
In computer networking, localhost is a hostname that means this computer and may be used to access the computer's own network services via its loopback network interface.
Source: https://en.wikipedia.org/wiki/Localhost
In other words: every computer is its own "localhost", not just yours, and generally MySql and other database engines use localhost as default value.
See also https://dev.mysql.com/doc/refman/5.0/en/connecting.html
If you want to have your database accessible from the net without to use an external hosting service you have to keep your computer running 24/7. Don't forget to buy a good UPS (uninterruptible power supply).

I need some major help in setting up my android app to add/receive data to/from my database. I'm using Amazon's RDS service in connection with xampp's phpMyAdmin. I've already successfully connected my DB instance to the database in phpMyAdmin. Also, I've written my php scripts to do basic CRUD (Create, Read, Update, Delete) commands in SQL. I've been following this tutorial.
The problem for me is, in his tutorial he is using strings like this:
private static String url_all_products = "http://api.androidhive.info/android_connect/get_all_products.php";
to run his php scripts in a call to makeHttpRequest(url_all_products). But I don't have my own website to do this and I'm pretty sure I don't need one to do this.
Next, I have a test.php file that does a simple echo statement and it works when I run this in a web browser:
http://localhost/phpfiles/test.php
Which leads me to my second problem. I don't want to use localhost because I need these php files and the ability to retrieve data from the database to be accessible to anyone using my app. This is the sole reason I'm using Amazon's RDS service so my database can be accessed on the cloud.
So how can I use the host address provided to me by Amazon RDS to access the database and where do I store all the php files so I can properly use them in Android the way the tutorial shows? They are currently saved in xampp/htdocs/phpfiles/.
I feel like I'm missing some fundamental understanding of all this and I'm going about it all wrong. If someone can point me in the right direction that would make my day.
It sounds like you don't really need the XAMPP install on your local machine at all. You're hosting this on Amazon and you want it to be available to the internet, so your local computer isn't involved. You can use XAMPP locally for testing and development, but for production use you'll be exclusively on the Amazon RDS cloud.
But I don't have my own website to do this and I'm pretty sure I don't need one to do this.
You may not want a website, but you do want your services hosted on the internet. That's what your RDS instance is for, and technically the tutorial is referring to an API which happens to be exposed through a web page. This is a much better idea than opening MySQL directly to the internet on port 3306.
You'll then use your Amazon host — for which you really should use a FQDN such as api.example.com rather than the IP address, but the IP address will work just fine from a technical aspect.
The files you refer to are on your local XAMPP installation; in the xampp/htdocs/phpfiles/ folder, and need to instead be on the RDS instance.
Then your application accesses the API you expose in those files which return information back to your application.
Basically, I want to create an application like this:YOUTUBE
I want to create an application that when I add some information from my web host (either PHP or MYSQL) VB.NET will read it.
From your website you'll need to insert the data into your MySQL database.
The problem with using the database provided by your web host is that the chances are, due to 'Security Reasons' the will have disabled external access.
This means that any files outside of your web server (your sites root/sub directory) will not be able to access the data. So, while your website will be able to connect without a problem, your program will not.
Some hosts give its customers the opportunity to add an IP address to a white list which enables them to bypass their security system. However, most will not give you this option.
My suggestion is that you either rent a VPS where you can run both the WebServer and Your MySQL database (and PHPMyAdmin) from or Set Up A MySQL database on your PC (its not that difficult just read the manual and youll be fine). If you had a VPS then you would no longer need your pre hosted webserver as you could run your own. You would need to point your domain name to your VPS webserver. It will act just like any other.
By running your own MySQL Databse you are given the option to enable remote access. This means that any external entity with the correct details will be able to connect.
If you cant get a VPS or don't want to run your own server or rent a server that allows for external access. Check out db4free.net .They provide you with a free MySQL Database with external access for Developers to test out their systems. They are not ultra fast so that's something you may want to be aware of. Another thing is that your data that's held can be removed at any time. The servers are not there to be used permanently just for testing.
So how do I connect to it through VB???
Good Question! To establish a connection, I suggest you use MySQL.Data library provided my DevMySQL themselves and import it into your program. Done so by Imports MySQL.Data.MySQLClient. This is written by them to work with their databases. Yes you can connect using some of the functions already in VB but in my opinion they don't work as efficiently. You'll need to download the MySQLConnector to connect as well.
Hopefully That Answers Your Questions. Any Problems Just Comment below!

Good day. I have a thesis project. it is composed of a webpage created on php and a system using vb.net 2008.
As of now , they are both connected to the same database.
I am wondering if it is possible that if i packaged the system and live the website, will still be connected with one database? Thank you in advance.
If I understand you right (and the question could be better worded), you're asking what happens if you deploy the website on a different server than the one you used to develop it. The short answer is that, unless the machine hosting the database is accessible to the web server host machine, that you would also have to redeploy the database.
In other words, wherever you move the PHP-based website and VB.NET system, they would need to be able to access the machine hosting the database server. Otherwise, I see no issue with them both accessing the same database.
Good day!
I've searched for many sites on how I could deploy my PHP projet in the internet but I don't know how to do it because I am confused with some of the technical terms.
You see, I am using xampp for my local web server. Now I want to put it in the internet. I found some free web hosting sites so i've decided to upload all my htdocs files inside it.. But how can I put the xampp (apache server) and my mysql database on it? I'm confused. Please help. A step-by-step procedure of what should i do could be really helpful. Thank you in advance.
Get a hosting account (try www.bluehost.com for instance).They will set you up with a Linux server and MySQL. You don't have to install Apache or MySQL, you will use whatever they've got. All you need to do is upload your PHP files to the right folder, setup your database on their server and you should be good to go.
If you buy a domain-name and space, connect them using the NS settings
If you are using a free, then the settings are already okay.
Export the database from your XAMP.
Login to the remote server. There you'll find PHPMyAdmin. Import the database.
Upload the file.
Make sure file listing is off. That is if a user goes to any directory he can not see the file list!
Done :)
Simplifying a bit, there are two ways you can get your site online.
First, you could purchase or rent a server that is yours and yours alone. This is commonly called "dedicated hosting" and costs somewhere around $100 / month. If you choose this option, you have your own server housed in a datacenter somewhere, and you must install Apache, MySQL, and any other server software you care to use.
I doubt, given what you've described, you have chosen this option.
Second, you could rent "shared hosting" from any one of the dozens of hosting providers out there. If you do this, with a typical cost of $2 to $10 per month, the hosting provider is administering the server. You have no direct access at all. Your only access is through the tools they provide.
Given that, how specifically you can upload files is up to them (is it FTP? SSH? a horrifying web-based upload tool of some kind?) Similarly, how you access your MySQL databases (assuming they offer MySQL databases) is entirely up to them as well.
Many providers now use a tool called cPanel for this administration, so you may try browsing to www.example.com/cPanel (using your domain) on the off chance that works. If not, though, follow the instructions your host provides. Only they can correctly describe how their setup works.
The hosting will be already having apache and mysql installed you only have to put your files thats it
I suggest you contact your webhosting site. The web hosting needs to host php, and mysql. Then you can upload your files to their web server, and copy your mysql database to their mysql server.
You do not need to transfer xampp to your host: apache and mysql are running on nearly every server
Upload all your files in your htdocs directory via ftp to your server
To transfer your database, use phpMyAdmin. It is installed with xampp and alos installed on nearly every server. In phpMyAdmin, use the export/import functionality
In your php file where you connect to the db change the login settings to the settings the hoster gave you
That should work...
Hosting Company already have setup for apache,php, mysql. All you need to uploads all your
files from xampp htdocs to a right folder like public_html using a ftp software like
filezilla. They also provide a control panel like using which you can manage your mysql
database and all others settings like directory permission.
i need to make a website such that it can be accessed through the internet if internet is available otherwise when there is no internet then it should work properly on the local intranet also can this be achieved , i have built my site on php/mysql
if this can be achieved please tell me and direct me to some examples of how to achieve this
thankyou

If you have a local web server, why not just host everything from there instead of hosting it elsewhere, and set it up so incoming connections from the outside hit that machine as well.
Or set up a remote sync that will keep all files on the remote server and the local server sync'd up. Could change DNS upon internet outage and have it resolve to the local server?
This will depend on how your network is configured, there are two likely scenarios that I can think of:
Your web server is behind a router and port 80 is forwarded
Your web server has it's own IP address on the internet
In the first instance you shouldn't have to do anything unless you want to access the website using a URL (e.g. www.mywebserver.com) in which case you'll have to play some DNS tricks on the local network to get it to point to the local IP of the server instead of the actual internet IP. For example when accessed from the internet the dns record for www.mywebserver.com would point to 12.34.56.78 where as the dns record for any machine on the local network would be something like 192.168.0.10.
In the second case to my knowledge there is nothing you can do that will allow you to be able to access on the intranet (I could be wrong so if someone posts a solution in this case I'll update my answer).
So the answer to your question really depends on your network configuration, If you expand on that a little giving a more concrete answer will be a little easier.
