For webserver Configuration, we only need to setup LAMPP in linux system and edit the IP tables to access the server from the remote computer.To do this, follow the following Steps

1 INSTALLING MYSQL 5 To install MySQL, we do this:

#yum install mysql mysql-server

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

#chkconfig –levels 235 mysqld on

#/etc/init.d/mysqld start

To Set passwords for the MySQL root account:

# mysql_secure_installation

2. Installing Apache2

#yum install httpd => This command install APache

Now configure your system to start Apache at boot time…

#chkconfig –levels 235 httpd on

#/etc/init.d/httpd start

Now direct your browser to http://192.168.0.100, and you should see the Apache2 if your setup has been good you will see the following page

Webserver Configuration

Apache HOME PAGE

Apache’s default document root is /var/www/html on CentOS, and the configuration file is /etc/httpd/conf/httpd.conf. Additional configurations are stored in the/etc/httpd/conf.d/ directory.

4 Installing PHP5

We can install PHP5 and the Apache PHP5 module as follows:

#yum install php

We must restart Apache afterwards:

#/etc/init.d/httpd restart

Making Apache to ACCESS FROM REMOTE COMPUTER
Apache wouldn’t work off the bat if you’re trying to see it from another computer…you have to add a firewall exception:
…first turn it off:

# service iptables stop

and edit the configuration files

# vi /etc/sysconfig/iptables

We need to add a rule

-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

Start start firewall again

#service iptables start

…if you want to remotely access MySQL as well (I do) you also add:

-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT

5 Testing PHP5 / Getting Details About Your PHP5 Installation

 The document root of the default web site is /var/www/html. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.
#vi /var/www/html/info.php
 we call that file in a browser (e.g. http://192.168.0.100/info.php):

6 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It’s a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

#yum search php

Pick the ones you need and install them like this:

#yum install php-mysql php-gd php-imap php-ldap php-mbstring php-odbc php-pear php-xml php-xmlrpc

APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It’s similar to other PHP opcode cachers, such as eAccelerator and Xcache. It is strongly recommended to have one of these installed to speed up your PHP page.

APC can be installed as follows:

#yum install php-pecl-apc

Now restart Apache2:

#/etc/init.d/httpd restart

Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules there, including the MySQL module:

7 phpMyAdmin

phpMyAdmin is a web interface through which you can manage your MySQL databases.

First we enable the RPMforge repository on our CentOS system as phpMyAdmin is not available in the official CentOS 6.3 repositories:

Import the RPMforge GPG key:

#rpm –import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt

On x86_64 systems:

#yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

On i386 systems:

#yum install http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm

phpMyAdmin can now be installed as follows:

#yum install phpmyadmin

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory “/usr/share/phpmyadmin”> stanza):

#vi /etc/httpd/conf.d/phpmyadmin.conf

Web application to manage MySQL
#

#<Directory "/usr/share/phpmyadmin">
#  Order Deny,Allow
#  Deny from all
#  Allow from 127.0.0.1
#</Directory>

Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin

Next we change the authentication in phpMyAdmin from cookie to http:

#vi /usr/share/phpmyadmin/config.inc.php

[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]

Restart Apache:

#/etc/init.d/httpd restart

Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:
