The setups of virtual directory, or virtual hosting are very convenient. In Apache, actually the virtual hosting is a virtual directory, so the setup of virtual hosting, and the setup of virtual hosting are complete the same. As the codes below which in the file of httpd.conf, is the default setting of http://localhost in the httpd.conf file:

<VirtualHost *:80>
ServerName localhost
DocumentRoot F:/site
</VirtualHost>

Follow suit, if I want to use http://ww2.auciou.com to browse and test my Blog, copy the 4 lines of code as above, then change the values of ServerName in Line 2, and DocumentRoot in Line 3. The codes after change is as below:

<VirtualHost *:80>
ServerName ww2.auciou.com
DocumentRoot F:/site/auciou
</VirtualHost>

Then restart Apache, as well you may create many virtual hostings at local.

Open the file of C:\WINDOWS\system32\drivers\etc\hosts, write a line as below:
127.0.0.1 ww2.auciou.com

Then you may use Apache as the local virtual hosting to preview your own Blog, as the photo below:

The simple and convenient installation of Apache and PHP, please view this article which was written by me http://www.auciou.com/peace/78. All of my present development environments, are based on this background of Apache and PHP, need not to reinstall Apache and PHP after reinstall the system.

As the preceding approach, http://www.auciou.com/peace/78 (Reinstall Apache and PHP for one step), after create the development environment of Apache, while reinstall the system, you may reinstall Apache and PHP for just one step. The essential of create the development environment is revising the apache\conf\httpd.conf file, this file needs to be backuped, set for one time, hereafter need not to set it repeatedly. Here I'll briefly introduce the approach that change the port, create the virtual hosting, change the main directory of default local sites.

Take the article before, for instance, all the same, the system is Win XP, create the folder D:\server:
Apache extracts at D:\server\apache;
PHP 5 extracts at D:\server\php5.

All of the settings below, we will change the file D:\server\apache\conf\httpd.conf, please open this file by a text tool.

1. Change the port. If you depend on PHP development, I suggest that do not change the port, the default port is 80. If you need to change the port, for instance, I change the port to 60. Find "Listen 80", change to Listen 60, restart Apache. Then you may use http://localhost:60 to visit the main directory.

2. Create the virtual hosting. For instance, my site's long-distance address is http://www.auciou.com, in order to simulate the effect of long-distance, as well I can make my local computer as a server. In order to avoid that the accidental mess of operations of local and long-distance happens, we may use a sub domain to simulate, the sub domain of 3 characters is the best, as ww2.auciou.com, or wwa.auciou.com. (Commentary: this sub domain, just revise the local file "hosts", do not need to add on the domain management.)

   The approach of creating a virtual hosting: write the codes as below at any position in the httpd.conf file:

   <VirtualHost *:80>
   ServerName ww2.auciou.com
   DocumentRoot F:/site/auciou
   </VirtualHost>

   Commentary: the third line DocumentRoot F:/site/auciou, is the path of my blog in the local harddisk. Then open this file C:\WINDOWS\system32\drivers\etc\hosts, write a line as below:

   127.0.0.1 ww2.auciou.com

   The virtual hosting have been set up, restart Apache, then you may use http://ww2.auciou.com to visit the local sites. To set for many virtual hostings, are the same steps. (In addition, if you use IIS for a few, you may use the Port 80 for Apache and PHP, IIS uses the Port 50 or others.)

3. Change the main directory of default local sites, that's to say that revise the corresponding directory of http://localhost.
   Find ServerRoot c:/www
   Change to ServerRoot F:/site

   At last, restart Apache.

The 2 softwares we need:
MiniApache (V2.0.5.2)
php-5.2.8-Win32.zip

The development environment of this article is Win XP. While the PHP runs with IIS, it is very slow. Run PHP with Apache, the speed will be faster for much. MiniApache (2.0.5.2) is a simplified Apache, it is just 308 K. As the introduction said, the functions that used frequently are not reduced.

After I installed and tested for many times, I've known well this installation of MiniApache. In order to avoid reinstalling Apache and PHP after reinstalling the system, please install them in the Disk D, for example, I install at D:\server. Create the development environmen of yourself first, the steps of installation are:

1. Extract the MiniApache at D:\server\apache.
2. Open the file D:\server\apache\setup.cmd, by a text tool, find that c:\www\bin\apache -k install, c:\www\bin\apache -k uninstall, and c:\www\bin\apache -k restart, delete all of the keyword "c:\www\", they will become bin\apache -k install, etc., this makes the DOS command become the relative path. Otherwise while run setup.cmd, it takes error, disable to install.
3. Configure the file D:\server\apache\conf\httpd.conf first, then install Apache. Such as change the port, create the virtual hosting, change the main directory of local site, all of them are written the correlative codes in the httpd.conf configuration file, in order to understand more easily for you, I omit this step. (Please click here to view detail, http://www.auciou.com/peace/79)
   httpd.conf file must be written the 3 lines as below:

   PHPIniDir D:/server/php5
   LoadModule php5_module D:/server/php5/php5apache2.dll
   AddType application/x-httpd-php .php

   Explanation: the second line is "Load Module", if without the third line, PHP cannot run, it just can display the HTML page.
   DirectoryIndex index.html this line is the default document of the directory, change to DirectoryIndex index.php index.html

4. In the file of httpd.conf, replace all of the keyword "c:/www" to "D:/server/apache", otherwise it cannot run. Because the MiniApache's default directory of installation is c:/www, I install at D:/server/apache.
5. Then run setup.cmd, choose 1, press Enter, if favoring, the installation of Apache will finish.
6. Install PHP 5. Extract php-5.2.8-Win32.zip at D:\server\php5, rename the D:\server\php5\php.ini-dist to php.ini, do not need to configure.
7. At this time, Apache and PHP have been installed completely. If PHP does not run, please open D:\server\apache\setup.cmd, choose 3, Enter, restart Apache.

Hereafer, after reinstall the system, just double click D:\server\apache\setup.cmd, choose 1, Enter, install, Apache and PHP will be installed for just one step.

The program of preventing the spam and closing IP which designed by me, had been used for several months on ufoaq.com, the effect was very good, not only simple, but also highly effect, it is simpler than the program which designed by me in 2006. Generally, the program of preventing the spam was via that write the Cookies, the program of closing IP was via that write the Cookies and read the IP list from the database, this article will take PHP, for instance. Because this program needs to write the Cookies, please write <?ob_start();?> at the very head of the very outer of such as post.php, reply.php, submit.php, otherwise it will take error.

The elements of program of preventing is as below, this program is written in the common module such as judge.php, this file is includeed by the other files with the include() function.

<?$te=30; //You could set this value for the time which just can post for one time in 30 seconds, if omit $te=30;, the default value is 60.
if (!$te) $te=60;
$t9=time();
if ($t9-$_COOKIE[te]<$te) $kx.="The time between you post for 2 times should be more than ".$te." seconds, please post ".$te." seconds later.";
if ($kx) {……} //Take error to the poster, and the program will not run.
?>

Then write Cookies in post.php, as below:
<?if (!$kx) setcookie("te",$t9,$t9+$te,"/");?>

The program of closing IP is below:

<?$ip=$_SERVER["REMOTE_ADDR"];
$i=…… //$i was the IP list which reed from the database, such as the value of $i is "125.33.125.255,133.134.99.1", many IPs are spaced out by comma, this value can be revised in the background of site. Because the configurations of background of site are different, this article will not explain the program which how to revise this value, please write the program by yourself. Because the program below uses the strpos() function, not uses the circle program to judge that whether the IP of user exists in the $i value, you may set for many IPs which you want to close, several hundred IPs will not affect the efficiency of program for much. While the user-side write the Cookies, the user's IP is closed completely, you may delete all the value of $i.
$j=$_COOKIE[pe];
$h="Your IP is closed.";
if ($j) $kx.=$h;
elseif (strpos($i,$ip)!==false){$kx.=$h;
if (!$j) setcookie("pe","50",time()+86400*9,"/");}
if ($kx) {……} //Take error to the poster, and the program will not run.
?>
