Installation, configuration, and implementation of Apache HTTP Server Source Code

Introduction to Apache HTTP Server

The most famous and functional web server in Linux is Apache HTTP Server (APACHE ).

Apache HTTP Server is one of the most famous open-source projects of the Apache Software Foundation. It can run on most operating systems.

The main official website versions are 2.2 and 2.4. Centos 6 uses Version 2.2 and centos 7 uses version 2.4.

Most versions 2.2 are deployed in the current production environment, but version 2.4 has many new features. The following is a brief description:

(1) MPM can be dynamically loaded during runtime

In version 2.4, mpm can be programmed into a load-able module. During running, you only need to configure what MPM to use.

(2) event MPM supported

Officially supports event mpm, which was previously tested.

(3) Better asynchronous read/write support

(4) use different log levels in each module and Directory

(5) You can use <if>, <elseif>, and <else> configurations for each request.

(6) Enhanced expression Analyzer

(7) keepalivetimeout can be controlled in milliseconds

(8) The namevirtualhost command is no longer required

(9) User-Defined variables can be used in configuration

(10) Use less memory than Version 2.2

(11) added many new modules, such as mod_proxy_fcgi, mode_ratelimit, mod_request, and mod_remoteip. At the same time, many modules are also enhanced.

(12) changes in access control

2.2 Configuration:

Order deny, allow
Deny from all

2.4 Configuration:

Require all denied

2.2 Configuration:

Order allow, deny
Allow from all
2.4 Configuration:

Require all granted

2.2 Configuration:

Order deny, allow
Deny from all
Allow from example.org

2.4 Configuration:

Require host example.org

As v2.4 introduces so many new features, it is also necessary to install v2.4 in the production environment.

 

Compile and install

Preparations

Download httpd-2.4.10.tar.bz2 from the official website

The lab environment is centos 6.5. Version 2.2 is installed by default and v2.2 is stopped.

[[Email protected] named] # service httpd stop
[[Email protected] named] # chkconfig httpd off
[[Email protected] named] # chkconfig -- list httpd
Httpd 0: off 1: off 2: off 3: off 4: off 5: off 6: Off
[[Email protected] ~] # Tar xf httpd-2.4.10.tar.bz2

APR Installation

Httpd depends on Apr (Apache Portable Runtime), and version 2.4 depends on a newer version of APR, which must be 1.4 or later. Centos 6 is installed with 1.3.9

Download apr-1.5.1.tar.bz2and apr-util-1.5.3.tar.bz2 from http://apr.apache.org.

[[Email protected] ~] # Tar xf apr-1.5.1.tar.bz2
[[Email protected] ~] # Tar xf apr-util-1.5.3.tar.bz2

[[Email protected] ~] # Cd apr-1.5.1

[[Email protected] apr-1.5.1] #./configure -- prefix =/usr/local/apr15

[[Email protected] apr-1.5.1] # Make & make install

[[Email protected] ~] # Cd ~ Apr-util-1.5.3

[[Email protected] apr-util-1.5.3] #./configure -- prefix =/usr/local/aprutil15 -- With-Apr =/usr/local/apr15/

[[Email protected] apr-util-1.5.3] # Make & make install

Install httpd

Common configure options

Name	Description	Value
-- Prefix	The installation directory of the program. It is installed in/usr/local/apache2 by default.	/Usr/local/apache24
-- Sysconfdir	Configuration file directory	/Etc/httpd24
-- Enable-so	Enable DSO
-- Enable-Modules	List of modules separated by blank characters, which can also be "all" | "most" | "few" | "NONE" | "reallyall"	Most
-- Enable-SSL	SSL/TLS support (mod_ssl)
-- Enable-CGI	CGI supported
-- Enable-Rewrite	Server rewrite
-- With-PCRE	Use the PCRE Library
-- With-Apr	Specify the APR path	/Usr/local/apr15/
-- With-Apr-util	Specify the APR-util path	/Usr/local/aprutil15/
-- With-z	Use zlib library
-- Enable-MPMs-shared	The MPM module dynamically loads the list separated by blank characters, which can be all	All
-- With-MPM = mpm	Default processing model used by Apache, mpm = {event | worker | prefork | winnt}	Event

Installation directory and file description

/Etc/httpd24	Configure the main directory
/Etc/httpd24/extra	Additional configuration directory
/Etc/httpd24/httpd. conf	Main configuration file
/Usr/local/apache24/htdocs	Site root directory
/Usr/local/apache24/Error	Preset error document directory
/Usr/local/apache24/cgi-bin	CGI directory
/Usr/local/apache24/include	Header file directory for secondary development, which can be exported if necessary
/Usr/local/apache24/man	Help manual, export required
/Usr/local/apache24/modules	DSO Module Directory
/Usr/local/apache24/bin	Executable File directory
/Usr/local/apache24/logs	Log directory

Export bin directory

[[Email protected] ~] # Cd/etc/profile. d/
[[Email protected] profile. d] # Vim httpd24.sh
Path =/usr/local/apache24/bin: $ path
Export path

Then restart the connection session.

Export man directory

Add one in/etc/man. config

Manpath/usr/local/apache24/man

To take effect

Export the header file directory

[[Email protected]/] # ln-S/usr/local/apache24/include // usr/include/Apache

Apachectl

Apachectl is a shell script in/usr/local/apache24/bin. It can be used to control the startup, shutdown, restart, elegant restart, and elegant shutdown of httpd.

The so-called elegance means that the connection will not be terminated immediately if there is a connection before it is restarted or closed.

Start the first time

[[Email protected] ~] # Apachectl start

[[Email protected] ~] # SS-tnlp | grep: 80
Listen 0 128: 80: * Users :( ("httpd", 2308, 4), ("httpd", 2309,4), ("httpd", 2310,4 ), ("httpd", 2311,4 ))
