Detailed step-by-step tutorial for PHP modular installation

This article mainly introduces the method of PHP modular installation. It analyzes the steps and related precautions of PHP modular installation in more detail. It has certain reference value. Friends in need can refer to it

PHP (Hypertext Preprocessor) is a simple but very powerful scripting language. The installation and basic configuration process of Apache2.0.53 php5.2.1 based on the WindowsXP sp2 operating platform is recorded below for reference:

1. First download the following programs from official websites:

1. apache_2.0.53-win32-x86-no_ssl.exe
2. php-5.2. 1-Win32.zip (binary compressed package)

2. Installation and configuration process:

1. Install apache Web server:

Double-click the installation file apache_2.0.53-win32-x86-no_ssl.exe and install it in the D:/Apache directory (I created a new Apache folder on the D drive),

--- -------------------------------------------------- --
Note: The following problems may occur during the installation process:
OS 10048 Normally each socket address (protocol/network address/port) is only allowed to be used once:
make_sock: could not bind to address 0.0.0.0:80...” It is usually caused by IIS occupying port 80
Two solutions:
1. Open the Control Panel->Services, find the IIS admin service, close it and disable it
2 . If you don’t want to close the IIS service, you can change the port used by apache to another port
Change Listen 80 in apache2/conf/httpd.conf to Listen (the port you want to use) such as Listen 8080
But at this time When you access the web service under your apache, add the port number
after the domain name, such as: http://localhost:8080
---------------- ---------------------------------------

Test whether Apache is installed successfully , will be entered in the browser: http://localhost:8080/http://localhost If you can see the Apache logo feather, Congratulations!!!

2. Install PHP:

Extract the contents of php-5.2.1-Win32.zip to D:/PHP (I created a new PHP folder on the D drive) and find php.ini-dist in the php directory. Name it php.ini and copy it to the windows directory. Then copy php5ts.dll and libmysql.dll in the D:/PHP directory to the system directory (under windows/systems32).

Configure httpd.conf in apache

Open the file D:/Apache2/conf/httpd.conf
Find AddDefaultCharset ISO-8859-1 and add it Change to AddDefaultCharset GB2312 (let the default language encoding be Simplified Chinese)
Find DocumentRoot "D:/Apache2/htdocs" and change it to your WEB directory (optional). For example, mine is DocumentRoot "G:/Web Project"
Find DirectoryIndex index.html index.html.var and add index.htm index.php at the end

Select the installation mode: modular mode installation or CGI mode installation (select one)

Modular installation configuration

Find the line #LoadModule ssl_module modules/mod_ssl.so and add a line after this line:

LoadModule php5_module d:/php/php5apache2.dll

Among them, d:/php/php5apache2.dll is the location of php5apache2.dll in your php directory.

Note: LoadModule php5_module d:/php/php5apache2.dll
//Note : Where C:/php5/php5apache2.dll is the corresponding path for you to install php. Do not confuse php5apache2.dll with php5apache2_2.dll.

php5apache2.dll is only applicable to apache 2.0 version.

If it is apache2.2.* or above, "Cannot load C:/php/php5apache2.dll into server: The specified module could not be found." or: "The requested operation has failed"

Find the line AddType application/x-gzip .gz .tgz and add a line after this line

AddType application/x-httpd-php .php

CGI installation configuration

Find the AddType application/x-gzip .gz .tgz line and add the following:

ScriptAlias /php/ "d:/php/" AddType application/x-httpd-php .php Action application/x-httpd-php "/php/php-cgi.exe"

Note: The full English name of CGI is Common Gateway Interface, which is usually translated as common gateway interface. It is an interface for the HTTP server to communicate with other programs on the machine. This "other program" can be written in any computer language. It obtains input from the HTTP server through the CGI interface, and then sends the running results to the HTTP server through the CGI interface, and the HTTP server sends the results to the browser.

The emergence of CGI has changed the WEB from static to dynamic. As the Web becomes more and more popular, many websites need dynamic pages to interact with viewers. The shortcomings of CGI methods are also becoming more and more prominent. Because HTTP needs to generate a dynamic page, the system must start a new process to run the CGI program. Continuous forking is a very time- and resource-consuming task. Here comes FastCGI.

FastCGI is like a long-live CGI. It can be executed all the time. As long as it is activated, it will not take time to fork every time (this is the most criticized thing about CGI). fork-and-execute mode).

At this point the PHP environment has basically been configured successfully

Create a file named test.php in the WEB root directory (such as my D:/website) with the following content

Restart the apache service

Use a browser to open http://localhost/test.php or In LINUX system: /usr/local/php/bin/php -f test.php

If you can see the php configuration output information, it will be OK

Note:Modular installation of mod_php is to install PHP As a built-in module of APACHE. Let the apache http server itself support the PHP language, without starting the PHP interpreter for every request to interpret PHP.
