Hello Everyone,

In this tutorial,

Let us Install LAMP(Apache, MySQL DB, PhpMyAdmin) on Ubuntu Server & Desktop 12.04/14.04/14.10 -- 64 Bit.

You Can also Install in Linux Mint 17 or Debian 7.

                            Installation Apache

I'm running all the steps in this tutorial with root privileges, so make sure you're logged in as ROOT:                

Step1:- sudo su

Update ubuntu repositories by giving the below command

Step2:- sudo apt-get update & sudo apt-get upgrade -y

Step3:- sudo apt-get install apache2

Step4:- Testing Apache:-

http://localhost/ or http://server-ip-address/.

                           Installation MySQL

Step5:- sudo apt-get install mysql-server mysql-client

                                              or

sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

You can verify the MySQL server status using command:

Step6:- sudo service mysql status

Sample output:

mysql start/running, process 3470

                

                          Installation PHP

Step11:- sudo apt-get install php5 php5-mysql libapache2-mod-php5

Test PHP

Create a sample “testphp.php” file in Apache document root folder.

Step12:- sudo nano /var/www/html/testphp.php

Add the following lines.

&lt?php

phpinfo;

?&gt

Restart apache2 service:

Step13:- sudo service apache2 restart    or   /etc/init.d/apache2 restart

Testing testphp

e.g. localhost:testphp or http://192.168.0.100/testphp.php

If you want to install all php modules enter the command

Step14:- sudo apt-get install php* and restart the apache2 service.

To verify the modules, open web browser and navigate to

 http://server-ip-address/testphp.php.

 You will able to see all installed php modules.

                         Installation phpMyAdmin

Step15:- sudo apt-get install phpmyadmin

Web server to reconfigure automatically: -- apache2

Configure database for phpmyadmin with dbconfig-common? -- yes

Enter MySQL application password phpmyadmin   --- 123456

Step16:- Afterwards, you can access phpMyAdmin under:- http://192.168.0.100/phpmyadmin/

                             Installation MariaDB --- Optional

First you have to remove existing MySQL packages if any.

To completely uninstall MySQL along with its configuration files,

enter the following command:

Step7:- sudo apt-get purge mysql*

Run the following command to remove unwanted packages.

Step8:- sudo apt-get autoremove

Now, add MariaDB repository. Run the following commands to add PPA. Hence, MariaDB 5.5 repository is not yet updated to 14.04, we can use the repository of Ubuntu 13.10 instead.

Step8:- sudo apt-get install software-properties-common

          

 sudo apt-key adv --recv-keys-keyserverhkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db

       

sudo add-apt-repository 'deb http://ftp.yz.yamagata-u.ac.jp/pub/dbms/mariadb/repo/5.5/ubuntu saucy main'

Update the software sources list and install MariaDB using following commands:

Step9:- sudo apt-get update

           sudo apt-get install mariadb-server mariadb-client

Check if mariadb is running or not, using the following command:

Step10:-  sudo service mysql status

Sample output:

 * /usr/bin/mysqladmin  Ver 9.0 Distrib 5.5.37-MariaDB, for debian-linux-gnu on i686

To set or Reset MySql Root Password in Ubuntu 14.04 LTS

Once you have installed MySQL, we should activate it with this command:

Step2 :-  sudo mysql_install_db

sudo /usr/bin/mysql_secure_installation

The prompt will ask you for your current root password

root password. Go ahead and choose N and move on to the next steps

Remove anonymous users?  y 

Disallow root login remotely?  y

Remove test database and access to it?  y

Reload privilege tables now?  Y
