- I have installed WordPress MU in localhost (local computer).
- I am using Windows XP Operating System.
- I am using WAMP Server.

Problem:

When installing WordPress MU, I was getting the following error:-

Warning! Installing to http://localhost/ is not supported. Please use http://localhost.localdomain/ instead.

I was able to get rid of this warning message by commenting the following line (present at around Line 8 to 10) in index-install.php file present inside the wordpress-mu folder:-

if( $_SERVER[ 'HTTP_HOST' ] == 'localhost' ) {
	die( "<h2>Warning!</h2><p>Installing to http://localhost/ is not supported. Please use <a href='http://localhost.localdomain/'>http://localhost.localdomain/</a> instead.</p>" );
}

By doing this, I was able to install wordpress MU completely in localhost.

But, now I get a strange error. When I try to login to admin panel, I always get redirected back to the login page. I cannot access the dashboard.

Solution:

- Go to C:\WINDOWS\system32\drivers\etc
- Open the file named hosts in notepad
- At the end of the file, write the following:-
127.0.0.1 localhost.localdomain

- Reinstall WordPress MU using localhost.localdomain instead of localhost.

Suppose you have wordpress MU files in a directory named wordpress-mu. Then, you should type the following URL in the browser:-

http://localhost.localdomain/wordpress-mu/

Hope this helps and thanks for reading.

Here, I will show you how you can install sample data after you have installed Magento.

1) Download Sample Data zip file from Magento Website

2) Extract the zip file

3) Drop all the tables from your magento database. It would be easy to drop the magento database and then recreate it instead of dropping individual tables. This can be done either through Database Manager or PhpMyAdmin.

4) Import sample data sql file into your magento database.

# Remember that, you have to drop all tables from your magento database before importing the sample sql file. You will get error afterward if you import the sample data without dropping tables from your magento database. Therefore, step 3 is important.

5) Go to your magento installation folder and delete local.xml file present inside app/etc folder.

6) Reinstall magento (i.e. if you have uploaded magento inside http://yourdomain.com/magento then type the address in your browser’s address bar :))

# After your installation is complete, you may get error something like this:
Integrity constraint violation: 1062 Duplicate entry ’1′ for key 1

Check if app/etc, var, and media folders are writable. They should be writable. Change their CHMOD to 777.

Clear your browser cache or open your website in another browser and you are done :)

There are different ways to install Smarty.

1) You can simply supply the absolute path to the Smarty library file:-

require(‘/usr/local/lib/php/Smarty/Smarty.class.php’);

2) You can add library directory to PHP include_path

Copy the libs folder from the Smarty distribution to the mycode folder (for example, C:\apache\htdocs\mycode\libs\).

After this, you need to edit the php.ini file and add include_path = “.;C:\apache\htdocs\ mycode\libs\” where C:\apache\htdocs\mycode\libs\ represents the location of your libs folder.

3) You can set SMARTY_DIR constant manually

define(‘SMARTY_DIR’, ‘/usr/local/lib/php/Smarty/’);

require(SMARTY_DIR . ‘Smarty.class.php’);

4) A slightly more flexible way to setup Smarty is to extend the class and initialize your Smarty environment. So instead of repeatedly setting directory paths, assigning the same vars, etc., we can do that in one place.

I will be explaining the fourth way, i.e. extending the class and initializing Smarty environment.

At first, let us have a look on the directory structure that we must create. Suppose, our work folder is named ‘example’, then our directory structure should be as under:-

example

|

|_ _ _ _ _ _ _ smarty (this directory contains Smarty library files)

|

|_ _ _ _ _ _ _ classes (this directory contains class files that we create)

|

|_ _ _ _ _ _ _ smarty_temp (contains manually created Smarty directories)

|

|_ _ _ _ _ _ _ index.php

As stated at the beginning of this article, the Smarty library files are kept in the ‘smarty’ directory.

Smarty requires four directories which are (by default) named templates, templates_c, configs and cache. Each of these are definable by the Smarty class properties $template_dir, $compile_dir, $config_dir, and $cache_dir respectively. It is highly recommended that you setup a separate set of these directories for each application that will use Smarty. We create these directories inside ‘smarty_temp’ directory.

Now, let’s move to the class file which is kept inside the classes directory.

<?php
/**
* Loading Smarty library
*/
require_once 'smarty/libs/Smarty.class.php';</span></span>

/**
* Connection to Smarty package
*
*/

class ConnectSmarty extends Smarty
{
/**
* This function connects with smarty
* manage paths to smarty directories
* @access public
*/
function ConnectSmarty()
{
$this->Smarty();

$this->template_dir = 'smarty_temp/templates';
$this->config_dir = 'smarty_temp/configs';
$this->cache_dir = 'smarty_temp/cache';
$this->compile_dir = 'smarty_temp/templates_c';
}
}

?>

The above class is called in the index page. An object of the class is created. Then, the Smarty method called ‘assign’ is used to assign values to the template. Through assign method, you can explicitly pass name/value pairs, or associative arrays containing the name/value pairs. After that ‘display’ method is used to display the template.

</span><?php
require_once('classes/ConnectSmarty.class.php');

// create an object of the class included above
$smarty = new ConnectSmarty;

// assign content
$smarty->assign('name','Mukesh Chapagain');
$smarty->assign('address','Kathmandu, Nepal');

// display the content
$smarty->display('index.tpl');

?>

index.tpl is the template file which contains html and smarty code.

</span><html>
<head>
<title> Homepage </title>
</head>

<body>

The author of this tutorial:<br/><br/>
Name: {$name} <br/>
Address: {$address} <br/>

</body>

</html>

Note: I have not included Smarty library files in this zip file. You can download the Smarty library files from http://smarty.php.net/download.php or directly from http://chapagain.googlecode.com/files/smarty.zip

Thank You.

Customer:
Well, after much consideration, I’ve decided to install Love. Can you guide me through the process?

Tech Support:
Yes, I can help you, are you ready to proceed?

Customer:
Well, I’m not very technical, but I think I’m ready. What do I do first?

Tech Support:
The first step is to open your Heart. Have you located your Heart ma’am?

Customer:
Yes, but there are several other programs running now. Is it okay to install Love while they are running?

Tech Support:
What programs are running ma’am?

Customer:
Let’s see, I have Past-Hurt, Low Self-Esteem, Grudge, and Resentment running right now.

Tech Support:
No problem, Love will gradually erase Past-Hurt from your current operating system. It may remain in your permanent memory, but it will no longer disrupt other programs. Love will eventually override Low Self-Esteem with a module of it’s own called High Self-Esteem. However, you have to completely turn off Grudge and Resentment. Those programs prevent Love from being properly installed. Can you turn those off ma’am?

Customer:
I don’t know how to turn them off. Can you tell me how?

Tech Support:
With pleasure. Go to your start menu and invoke Forgiveness. Do this as many times as necessary until Grudge and Resentment have completely erased.

Customer:
Okay, done, Love has started installing itself. Is that normal?

Tech Support:
Yes, but remember that you have only the base program. You need to begin connecting to other Hearts in order to get the upgrades.

Customer:
Oops! I have an error message already. It says, “Error-program not run on external components. What should I do?

Tech Support:
Don’t worry ma’am, It means the Love program is set-up to run on Internal Hearts but has not yet been run on your Heart. In non-technical terms, it means you have to Love yourself before you can Love others.

Customer:
So what should I do?

Tech Support:
Can you pull down Self-Acceptance; then click on the following files: Forgive-Self; Realise Your Worth; and Acknowledge Your Limitations.

Customer:
OK, done.

Tech Support:
Now copy them to the “My Heart” directory. The system will overwrite any conflicting files and begin patching faulty programming. Also, you need to delete Verbose Self-Criticism from all directories and empty your Recycle Bin to make sure it is completely gone and never comes back.

Customer:
Got it. Hey!!! My Heart is filling up with new files. Smile is playing on my monitor and Peace and Contentment are copying themselves all over My Heart. Is this normal?

Tech Support:
Sometimes. For others it takes a while, but eventually everyone gets it at the proper time. So Love is installed and running. One more thing before we hang-up, Love is FreeWare. Be sure to give it and its various modules to everyone you meet. They will in turn share it with others and return some cool modules back to you.

Customer:
I promise to do just that. By the way, what’s your name?

Tech Support:
Just call me the Divine Cardiologist, also known as the Great Physician, or just “I AM.” Most people feel all they need is an annual check-up to stay heart-healthy, but the manufacturer (ME) suggests a daily maintenance schedule for maximum Love efficiency.

3. Installing ASP.NET

Then, I suppose you installed .NET Framework.

This much in enough to run simple .asp page but if you try to run .aspx (i.e. ASP.NET page extension) page, you cannot. The page will not run because ASP.NET is not installed yet in your computer although you have installed .NET Framework. ASP.NET should be installed in order to run .aspx pages.

How to install ASP.NET?

There are some steps you should follow to install ASP.NET in your computer. Well, I am feeling lazy (actually I am a lazy guy, a tortoise :D) to write down the steps here. You can visit the link below that describes very clearly about the steps to install ASP.NET and run .ASPX page.

http://www.geekpedia.com/tutorial25_Setting-up-your-ASP.NET-server-%28IIS%29.html

I myself followed this link to install ASP.NET in my computer for the first time.

5. MySQL Installation Problem

I had this problem and had a very tough and frustrating time with it. While I was installing a fresh copy of MySQL 5 in Windows XP, I got this problem. (I was installing it from the installer i.e. setup file.) The server was not starting and ‘error 0′ was displayed. I tried to start the server from the command line by typing “mysqld-nt –console” and then got the error “can’t create pid file: no such file or directory”. It was also displaying the message like “cannot create/write file C:\Program Files\MySQL\MySQL Server 5.0\data\com2.pid”.

Solution:

The main problem was my computer name. My computer name was ‘com2′. MySQL makes the file with the computer name in the directory of it’s data (in my case C:\Program Files\MySQL\MySQL Server 5.0\data\) . Now, it was unable to create a file named com2 (which was my computer name) because in WINDOWS you cannot make file/folder with the name com1,com2,com3… and so on.

Hence, I changed my computer name, restarted my computer and then reconfigured MySQL. All well done and MySQL started running.

Cheers,

Mukesh
