Objective

LAMP refers to a set of free software names that are typically used together to run dynamic Web sites or servers.

L:linux Operating System

A:apache (httpd) Web Services

M:mysql (MARIADB) database service

P:php/perl/python/ruby Script programming language

This article is mainly in the CentOS 7 environment installation, CentOS 6 with part of the description

First, the installation of http2.4

Centos 7 Default installation httpd 2.4,centos 6 default installation httpd2.2

Centos 7: If http2.4 is not installed, install via Yum

Yum-y Install httpd

Centos 6: Can only be installed by compiling

You must install development tools and server Platform development two pack groups in advance, as well as install Prce-devel packages, Prce packages can be installed via Yum

yum -y groupinstall "Development tools"
yum -y groupinstall "Server Platform Development"
yum -y prce-devel

httpd2.4 requires 1.4 or more versions of APR and Apr-util, so get both the source bundle first

Apr compilation and Installation

Tar xf apr-1.4.6.tar.bz2 -C /usr/local //tar the source package to /usr/local directory
Cd /usr/local/apr-1.4.6
./configure --prefix=/usr/local/apr //Configure the source and specify the installation directory
Make && make install // compile and install the source code

Apr-util Compilation and Installation

tar xf apr-util-1.4.1.tar.bz2 -C /usr/local
cd /usr/local/apr-util-1.4.1/
./configure --prefix=/usr/local/apr-util
make && make install

HTTPD Compilation and Installation

Tar xf httpd-2.4.10.tar.bz2 -C /usr/local

Cd /usr/local/httpd-2.4.10

./configure --prefix=/usr/local/apache //Specify the installation directory
--sysconfdir=/etc/httpd24 //Specify the configuration file directory
--enable-so //Enable module function
--enable-ssl //Enable ssl encryption
--enable-cgi //Enable cgi function
--enable-rewrite //can be overloaded
--with-zlib //Use zlib data
--with-pcre /use pcre data
--with-apr=/usr/local/apr //The associated program apr and directory
--with-apr-util=/usr/local/apr-util //The associated program apr-util and directory
--enable-modules=most //Maximize all modules
--enable-mpms-shared=all //Separately list all MPM modules
--with-mpm=perfork //Use perfork mode

Make && make install 

The./configure parameters can be used./configure--help View

The above is to list the meaning of each parameter, so in the layout of the division, in the configuration of the relevant parameters are separated by a space

Second, the installation of MARIADB

The default use of MySQL in CentOS 6 is mariadb, which is used by default in CentOS 7

Installation of MARIADB

Yum-y Install mariadb-server.x86_64systemctl start mariadb//Start MARIADB Service

installation of MySQL

Yum-y Install Mysql-serverservice mysqld start

MARIADB configuration file:/etc/my.cnf,/etc/my.cnf.d/*.cnf

Modify the/etc/my.cnf file

Add the following values

Innodb_file_per_table = ON//Generate database list skip_name_resolve = ON//No reverse solution

Once the installation is complete, run the mysql_secure_installation once and configure the MARIADB.

FLUSH privileges;            Clear permissions Create DATABASE Testab; Create an Testab data form

Third, the installation of PHP

Yum-y Install PHP

Compile and install:

Four, lamp environment test:

Because HTTPD is implemented as an HTTP protocol server, it can only respond and handle client requests statically, and in order to enable the server to respond dynamically to requests from clients, there are three ways to achieve this:

1) using the CGI protocol: the HTTPD server forwards the request through the CGI protocol to the interpreter of the program, the interpreter returns the running result to the HTTPD server, and then the interpreter destroys

2) using module, compile php into httpd extension module, through httpd dynamic call module to achieve

3) FastCGI: With FPM (FastCGI process Manager), let PHP run a single Apache-type model service, listen to a socket, and generate multiple child processes to handle the response, while the main process is only responsible for managing requests and controlling the health of the child processes. At this point, HTTP becomes a fastcgi client, and FastCGI becomes a simplified version of the HTTP protocol that enables PHP and HTTP to be used for communication.

PHP and HTTP used in a common way by compiling httpd PHP processing module, let httpd own PHP program, or use a dedicated PHP application Server PHP-FPM, it is responsible for processing PHP programs.

a.php Test combined with httpd

Modifying a data file for a previously configured virtual host

Change/data/virhost/www1/index.html to/data/virhost/www1/index.php

vim/data/virhost/www1/index.php

Change the content to the following PHP test code

<php? Phpinfo ();? >

Restart HTTPD Service

Systemctl Restart httpd

Access 172.16.45.21 from the browser to see the Phpinfo page

Where the virtual host configuration file/etc/httpd/conf.d/virhost1.conf content is as follows:

<virtualhost *:80>servername www1.chunlanyy.comdocumentroot "/DATA/VIRHOST/WWW1" <directory "/data/virhost /WWW1 ">options noneallowoverride nonerequire all granted</directory></virtualhost>

[[email protected] modules]# ifconfigeno16777736:flags=4163<up,broadcast,running,multicast> MTU inet 1 72.16.45.21 netmask 255.255.0.0 Broadcast 172.16.255.255

b.php connection to MySQL test

In the case where the MARIADB has been configured in the previous article

Modify the above file vim/data/virhost/www1/index.php content as follows:

<?php $conn = mysql_connect (' 172.16.45.21 ', ' root ', ' Chunlanyy ');                if ($conn) echo "OK"; else echo "Failure";? >

When you start the PHP service, when you access 172.16.45.21 through the browser, an OK indicates that the connection is normal

Systemctl Stop PHP display failure
