2. php core package :( php official website: http://www.php.net) unzip it

Use Apache + PHP in windows and select VC6

?

Integration of apache and php:

1. add the following lines in the D: \ phpStudy \ Apache2 \ conf \ httpd. conf file:

LoadModule php5_module "D:/phpStudy/PHP5/php5apache2_4.dll" # php5apache2-4.dll under the php installation directory

PHPIniDir "D:/phpStudy/PHP5/" # php installation directory

AddType application/x-httpd-php. php. phtml # specifies that if the file is. php or. phtml, it will be processed by php.

?

2. under The php installation directory: rename the php. ini-development file to php. ini.

3. search for extension_dir = "./" in php. ini to open this line and specify the ext file path under the php installation directory.

Extension-dir = "D:/phpStudy/PHP5/ext"

?

Test:

Create the test. php file in the htdocs directory under the apache installation directory. the code is as follows:

Phpinfo ();

?>

Restart apache: http: // localhost/test. php

?

3. MySQL database :( MySQL official website: http://www.mysql.com)

Test:

1. write a php code to test whether the code is successful.

$ Conn = mysql_connect ("localhost", "root", "root ");

If ($ conn ){

Echo "connect to mysql database OK! ";

} Else {

Echo "connection to mysql database is not OK! ";

}

?>

2. install phpmyadmin to test availability (manage mysql)

Installation method: decompress the package to the htdocs folder and enter the index. php file under the Directory.

Access Method: http: // localhost: 8000/phpMyAdmin/index. php

?

2. http://www.comsenz.com

1. download the discus Forum code

2. decompress the package to the htdocs folder.

3. modify the config. inc. php file:

$ Dbhost = 'localhost'; // database server

$ Dbuser = 'root'; // database username

$ Dbpw = 'root'; // database password

$ Dbname = 'discuz'; // database name

$ Pconnect = 0; // database persistent connection 0 = disabled, 1 = enabled

?

$ Database = 'mysql'; // type of the forum database. do not modify it.

$ Dbcharset = 'utf8'; // MySQL character set. optional values: 'gbk', 'big5', 'utf8', and 'latin1'. the reserved values are set according to the Forum character set.

?

$ Charset = 'utf-8'; // Default Character set on the forum page. optional values: 'gbk', 'big5', and 'utf-8'

$ Headercharset = 0; // force the forum page to use the default character set to avoid garbled characters on some server space pages. 0 = close 1 = Enable

?

$ Forumfounders = 'admin'; // UID of the Forum founder, which can be separated by commas.

Note: set short_open_tag = on in php. ini.

4. access the install. php file under discus to install the database.

After installation:

UCenter URL: http: // localhost/upload/ucenter

UCenter founder password: admin

DISCUZ! URL: http: // localhost/upload/bbs

Administrator access URL: http: // localhost/upload/bbs/admincp. php

Administrator account: admin administrator password: admin

UCenter Home URL: http: // localhost/upload/home

Administrator access URL: http: // localhost/upload/home/admincp. php

Administrator account: admin administrator password: admin

Configure the website on an apache server:

1. to create a web site in the apache server, you need to enable the httpd-vhosts.conf file add:

Note: Make sure that the dns client service is in the starting status.

2. the configured host must be registered on the DNS server or windows system for external access.

?

Ideas:

1. identify different virtual hosts through ports

I. Prepare for binding a site

1. develop website D:/myblog

2. configure our httpd. conf file?

Enable httpd-vhosts.conf

Note DocumentRoot "D:/apache/htdocs"

3. find the file conf/extra/http-vhosts.conf file

Template:

DocumentRoot "D:/myblog"

DirectoryIndex index. php index.html

Options FollowSymLinks

AllowOverride None

Order allow, deny

Allow from all

4. add the object relationship between the ip address and the domain name to the hosts file.

Path: C: \ Windows \ System32 \ drivers \ etc \ hosts

Add: 127.0.0.1www.moluo.com

5. test: access http://www.moluo.com: 80

?

2. add a new domain name to bind the ip address

1. develop a new website

2. configure the httpd-vhosts.conf to add a new VM

DocumentRoot "D:/myblog2"

DirectoryIndex index. php index.html

Options FollowSymLinks

AllowOverride None

Order allow, deny

Allow from all

3. make apache listen to port 82 in the httpd. conf file

Listen 82

4. add the object relationship between the ip address and the domain name to the hosts file.

Path: C: \ Windows \ System32 \ drivers \ etc \ hosts

Add: 127.0.0.1www.fengpeng.com

5. test: access http://www.fengpeng.com: 82

?

2. use ServerName to differentiate virtual hosts

1. develop website D:/myblog

2. Add configuration in httpd-vhosts.conf files

DocumentRoot "D:/myblog"

ServerName www.moluo.com

DirectoryIndex index. php index.html

Options FollowSymLinks

AllowOverride None

Order allow, deny

Allow from all

DocumentRoot "D:/myblog2"

ServerName www.fengpeng.com

DirectoryIndex index. php index.html

Options FollowSymLinks

AllowOverride None

Order allow, deny

Allow from all

3. add the object relationship between the ip address and the domain name in the hosts file.

Path: C: \ Windows \ System32 \ drivers \ etc \ hosts

Add: 127.0.0.1www.moluo.com

4. test: access http://www.moluo.com

Http://www.fengpeng.com access
