LAMP Architecture Overview

LAMP architecture is one of the mature enterprise website application modes at present. It refers to a complete set of systems and related software working together, which can provide dynamic web site services and its application development environment. LAMP is an abbreviation, including Linux operating system, Apache Web server, MysSQL database server, PHP (or Perl, Python) web programming language.

The main functions of each component are as follows:

(platform) Linux: as the basis of L.AMP architecture, it provides an operating system for supporting web sites, which can provide better stability and compatibility with other three components (AMP components also support windows, UNIX and other platforms).

(foreground) Apache: as the front end of LAMP architecture, it is a powerful and stable web server program. The server directly provides users with website access, sending web pages, pictures and other file contents.

(background) MySQL: as the back end of LAMAP architecture, it is a popular open source relational database system. In enterprise websites, business systems and other applications, various account information, product information, customer information and business data can be stored in MySQL database. Other programs can query and change these information through sQL statements.

(intermediate connection) PHP/Perl/Python: as three programming languages for developing dynamic web pages, it is responsible for interpreting dynamic web page files, communicating the web server and database system to work together, and providing the development and running environment of web applications. PHP is a widely used open source multi-purpose scripting language. It can be embedded in HTML, especially suitable for web application development.

When building the L.AMP platform, the installation sequence of each component is Linux, Apache, MySQL and PHP. Apache and MySQL are not installed in strict order. The installation of PHP environment is generally installed last, which is responsible for communicating the web server and database system to work together.

Apache installation

Close the firewall and transfer the software packages required by apache

Install environment dependent packages

yum -y install gcc gcc-c++ make pcre pcre-devel expat-devel perl

Configuring software modules

#Unzip file
cd /opt/
tar zxvf apr-1.6.2.tar.gz
tar zxvf apr-util-1.6.0.tar.gz
tar jxvf httpd-2.4.29.tar.bz2

#move file
mv apr-1.6.2 /opt/httpd-2.4.29/srclib/apr
mv apr-util-1.6.0 /opt/httpd-2.4.29/srclib/apr-util


cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \		#Specify the path where the httpd service program will be installed
--enable-so \					#Enable dynamic loading module support to enable httpd to further expand its functions
--enable-rewrite \				#Enable the web address rewriting function for website optimization, anti-theft chain and directory migration maintenance
--enable-charset-lite \			#Start character set support to support pages encoded with various character sets
--enable-cgi					#Enable CGI (general Gateway Interface) script program support to facilitate the external expansion of application access capability of the website

Compile and install

make -j 4 && make install

Optimize profile path

Optimize the configuration file path, and put the executable program file of httpd service into the directory of path environment variable for system identification

ln -s /usr/local/httpd/conf/httpd.conf /etc/
ln -s /usr/local/httpd/bin/* /usr/local/bin/

Add httpd system service

cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
chmod +x /etc/init.d/httpd
vi /etc/init.d/httpd
#!/bin/bash			#Insert a new line before the first line and add these three lines
# chkconfig: 35 85 21    #Level 35 automatic operation, 85th startup, 21st shutdown
# description: Apache is a World Wide Web server


#Add service to service manager
chkconfig --add httpd
#Open service
systemctl start httpd.service

Modify httpd service profile

--52 that 's ok--modify
Listen 192.198.80.130:80
--197 that 's ok--Uncomment, modify
ServerName www.ghp.com:80
