Configure LAMP (Linux, Apache, Mysql, PHP) on RHEL 6

LAMP -  Linux, Apache, MySQL and PHP, an open-source Web development platform/Web stacks, that uses Linux as the operating system, Apache as the Web server, MySQL as the DBMS and PHP as the  scripting language. Perl or Python is often substituted for PHP

Apache - Apache provides the mechanics for getting a Web page to a user. Apache is a stable, mission-critical-capable server, and it runs more than 65 percent of all Web sites on   the Internet. The PHP component actually sits inside Apache, and you use Apache and PHP together to create your dynamic pages.

MySQL - MySQL provides the data-storage side of the LAMP system. With MySQL, you have access to a very capable database suitable for running large and complex sites. Within your Web application, all your data, products, accounts, and other types of information will reside in this database in a format that you can easily query with the SQL language.

PHP- PHP is a simple and efficient programming language that provides the glue for all the other parts of the LAMP system. You use PHP to write dynamic content capable of accessing the data in the MySQL database and some of the features that Linux provides.

Now we are going to configure LAMP on RHEL 6

>>>details of the directory structure going to use

     Directory Structure

          /usr/local/src/lamp         : The Downloaded .The tar file will be saved here.

        /usr/local/lamp                 : This where we compile, install the source code

       /usr/local/lamp/apache     :  we will install Apache under this directory

       /usr/local/lamp/mysql       :  we will install Mysql under this directory

       /usr/local/lamp/php          :  we will install php under this directory

flush your firewall before you testing this

# iptables -F

# service  iptables  save

1:- Removing the already installed rpms

 >check whether the rpm's are already there

#  rpm -qa | grep httpd        <-- Installed

# rpm -qa | grep mysql           <-- Installed

# rpm -qa | grep php            <-- Not Installed

stop the services

# service  httpd    stop

# service  mysqld  stop

removing the Packages

# rpm  -e   httpd

# rpm  -e   mysql-server

2:-Downloading the .tar file

# mkdir  /usr/local/src/lamp               

# mkdir  /usr/local/lamp              

# cd /usr/local/src/lamp

#wget ftp://ftp.nz.freebsd.org/pub/phpweb/distributions/php-5.4.8.tar.gz

#wget https://archive.apache.org/dist/httpd/httpd-2.2.22.tar.gz

#wget http://cdn.mysql.com/archives/mysql-5.5/mysql-5.5.28.tar.gz

# yum   install   gcc    gcc-c++    cmake   ncurses-devel   libxml2-devel

#tar   -xvf  httpd-2.2.22.tar.gz

#  cd    /usr/local/src/lamp/httpd-2.2.22

#  ./configure --prefix=/usr/local/lamp/apache  --enable-so   --enable-mods-shared="most"

*/Checks some details about the machine.This script checks for lots of dependencies on your      system. For the particular software to work properly/*

*/ --prefix gives the installing location of http /*

*/ --enable-mods-shared="most" : List of modules we want to enable . here i choose to  enable most of the modules/*

#  make

*/ Compilation of the source code /*

 #  make install

*/ install configuration /*

# ll    /usr/local/lamp/apache

# /usr/local/lamp/apache/bin/apachectl  start

 # netstat -ntlp | grep httpd

Note: The default index.html is located inside the  /usr/local/lamp/apache/htdocs/index.html

 checking

"Now open up a browser and type    http://127.0.0.1  or http://yourip  you will get test page containing "It works!"  "

  # ln -s /usr/local/lamp/apache/bin/apachectl  /etc/init.d/httpd

                */create a soft link /*

  # chmod  755  httpd

3:-COMPILING MYSQL

#groupadd   mysql

#useradd   -g  mysql   mysql

#cd   /usr/local/src/lamp

#ll

#cd  mysql-5.5.28                    

#pwd

#tar   -xvf   mysql-5.5.28.tar.gz

#cmake    -DCMAKE_INSTALL_PREFIX=/usr/local/lamp/mysql   -DMYSQL_DATADIR =/usr/ local/ lamp/mysql/data

#make

#make install

#chown -R mysql:mysql  /usr/local/lamp/mysql

#/usr/local/lamp/mysql/scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/lamp/mysql/    \--datadir=/usr/local/lamp/mysql/data/

#cp  /usr/local/lamp/mysql/support-files/mysql.server  /etc/init.d/mysqld

#cp  /usr/local/lamp/mysql/support-files/my-medium.cnf  /etc/my.cnf

#chkconfig --add  mysqld # chkconfig --list mysqld

#service  mysqld  restart

#netstat  -ntlp | grep mysql

4:-COMPILING PHP

#cd  /usr/local/src/lamp/

#tar  -xvf  php-5.4.8.tar.gz

#cd    php-5.4.8.tar.gz

# ./configure    --prefix=/usr/local/lamp/php    --with-apxs2=/usr/local/lamp/apache/bin/apxs  \--with-mysql=/usr/local/lamp/mysql/

#make

#make install

#cp   /usr/local/src/lamp/php-5.4.8/php.ini-production   /usr/local/lamp/php/lib/php.ini

To Check the php module is installed properly

# /usr/local/lamp/apache/bin/apachectl -t -D DUMP_MODULES  |   grep   php

Tell apache to process file starting .php extension     

Open up the file "/usr/local/lamp/apache/conf/httpd.conf "   then add  " AddHandler  application/x-httpd-php  .php "  with in the  <IfModule mime_module> .......   </IfModule>

# vim  /usr/local/lamp/apache/conf/httpd.conf 

........................

<IfModule mime_module>

........................
