　　LAMP is a combination of operating system and open-source software stack. The acronym LAMP came from the first letters ofLinux, Apache HTTP Server, MySQL or MariaDB database, and PHP/Perl/Python.This tutorial describes how to install LAMP stack on Ubuntu 16.04,
however the steps described below should work on previous Ubuntu
versions such as Ubuntu 15.10/15.04/14.10/14.04/13.10 etc.
Install LAMP Stack On Ubuntu 16.04
1. Install Apache
　　Apache is an
open-source multi-platform web server. It provides a full range of web
server features including CGI, SSL and virtual domains.
　　
　　To install Apache, enter:
sudo apt-get install apache2Enable  and  start   your  apache
root@ubuntu:~# systemctl    enable  apache2　　
root@ubuntu:~# systemctl    start  apache2
　　
root@ubuntu:~# systemctl    status  apache2
　　

　　
● apache2.service - LSB: Apache2 web server
　　
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)
　　
   Active: active (running) since Wed 2016-03-02 09:23:37 PST; 1min 2s ago

   CGroup: /system.slice/apache2.service
　　
           ├─22328 /usr/sbin/apache2 -k start
　　
           ├─22331 /usr/sbin/apache2 -k start

Test Apache:
　　Open your web browser and navigate to http://localhost/ or http://server-ip-address/.

2. Install MySQL

　　MySQL is a>sudo apt-get install mysql-server mysql-client　　During installation, you’ll be asked to setup the MySQL “root” user password. Enter the password and click Ok.

　　Re-enter the password.

　　MySQL is installed now.
　　You can verify the MySQL server status using command:
　　On Ubuntu 16.04/15.10/15.04:
sudo systemctl status mysql　　On Ubuntu 14.10 and previous versions:
sudo service mysql status　　Sample output:
● mysql.service - MySQL Community Server　　
Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
　　
Active: active (running) since Mon 2015-10-26 14:23:01 IST; 28s ago

3. Install MariaDB
　　In case you want to use MariaDB instead of MySQL community edition, follow the steps given below.

　　MariaDB is a drop in replacement for MySQL. It is a robust, scalable and>　　First you have to remove existing MySQL
packages if any. To completely uninstall MySQL along with its
configuration files, enter the following commands one by one:
sudo systemctl stop mysqlsudo apt-get remove --purge mysql-server mysql-client mysql-commonsudo apt-get autoremovesudo apt-get autocleansudo rm -rf /var/lib/mysql/sudo rm -rf /etc/mysql/　　After removing MySQL, run the following command to install MariaDB.
sudo apt-get install mariadb-server　　Alternatively, you can install it using MariaDB repositoryif you want to try most recent version of MariaDB. Run the following
commands to add PPA. As of writing this, MariaDB PPA is not yet updated
to Ubuntu 16.04. However, we can use the repository of Ubuntu 15.10
instead.
sudo apt-get install software-properties-commonsudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943dbsudo add-apt-repository 'deb http://download.nus.edu.sg/mirror/mariadb/repo/10.1/ubuntu vivid main'　　Update the software sources list and install MariaDB using following commands:
sudo apt-get updatesudo apt-get install mariadb-server　　During installation you will be asked toset mysql ‘root’ user password. Enter the password twice, and complete
the installation.
　　Important Note: In Ubuntu 16.04/15.10/15.04, MariaDB won’t ask you to set root user password during installation.
　　Also, you can’t set password manually using the following command too:
mysql_secure_installation　　It will throw the following error.
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB　　
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
　　

　　
In order to log into MariaDB to secure it, we'll need the current
　　
password for the root user. If you've just installed MariaDB, and
　　
you haven't set the root password yet, the password will be blank,
　　
so you should just press enter here.
　　

　　
Enter current password for root (enter for none):
　　
ERROR 1698 (28000): Access denied for user 'root'@'localhost'Enter current password for root (enter for none):
　　To fix this error, log in to mysql prompt without password as root user:
sudo mysql -u root　　Then, run the following commands one by one in the mysql prompt:
use mysql;update user set plugin='' where User='root';flush privileges;\q　　That’s it. Now, set database administrative “root” user password using command. Press Enter and go with the default settings.
mysql_secure_installation　　Sample output:
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB　　
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
　　

　　
In order to log into MariaDB to secure it, we'll need the current
　　
password for the root user.  If you've just installed MariaDB, and
　　
you haven't set the root password yet, the password will be blank,
　　
so you should just press enter here.
　　

　　
Enter current password for root (enter for none):
　　
OK, successfully used password, moving on...
　　

　　
Setting the root password ensures that nobody can log into the MariaDB
　　
root user without the proper authorisation.
　　

　　
Set root password? [Y/n] y
　　
New password:
　　
Re-enter new password:
　　
Password updated successfully!
　　
Reloading privilege tables..
　　
... Success!
　　

　　
By default, a MariaDB installation has an anonymous user, allowing anyone
　　
to log into MariaDB without having to have a user account created for
　　
them.  This is intended only for testing, and to make the installation
　　
go a bit smoother.  You should remove them before moving into a
　　
production environment.
　　

　　
Remove anonymous users? [Y/n]
　　
... Success!
　　

　　
Normally, root should only be allowed to connect from 'localhost'.  This
　　
ensures that someone cannot guess at the root password from the network.
　　

　　
Disallow root login remotely? [Y/n]
　　
... Success!
　　

　　
By default, MariaDB comes with a database named 'test' that anyone can
　　
access.  This is also intended only for testing, and should be removed
　　
before moving into a production environment.
　　

　　
Remove test database and access to it? [Y/n]
　　
- Dropping test database...
　　
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
　　
... Failed!  Not critical, keep moving...
　　
- Removing privileges on test database...
　　
... Success!
　　

　　
Reloading the privilege tables will ensure that all changes made so far
　　
will take effect immediately.
　　

　　
Reload privilege tables now? [Y/n]
　　
... Success!
　　

　　
Cleaning up...
　　

　　
All done!  If you've completed all of the above steps, your MariaDB
　　
installation should now be secure.
　　

　　
Thanks for using MariaDB!
　　Check if mariadb is running or not, using the following command:
sudo service mysql status　　Sample output:
● mysql.service - LSB: Start and stop the mysql database server daemon Loaded: loaded (/etc/init.d/mysql) Active: active (running) since Mon 2015-10-26 14:26:36 IST; 2min 5s ago

4. Install PHP  (PHP7)
　　PHP (recursive acronym
for PHP: Hypertext Preprocessor) is a widely used open-source general
purpose scripting language that is especially suited for web developmentand can be embedded into HTML.
　　Install PHP with following command:
sudo apt-get update　　
sudo apt-get install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi  php7.0 libapache2-mod-php7
　　Test  your php version
root@ubuntu:~# php -v　　
PHP 7.0.3-3 (cli) ( NTS )
　　
Copyright (c) 1997-2016 The PHP Group
　　
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
　　
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
　　
root@ubuntu:~#
　　To test PHP, create a sample “testphp.php” file in Apache document root folder.
sudo vi  /var/www/html/testphp.php　　Add the following lines:
<?php　　
phpinfo();
　　
?>
　　Restart apache2 service.
　　On Ubuntu 15.10/15.04:
sudo systemctl restart apache2　　On Ubuntu 14.10 and lower versions:
sudo service apache2 restart　　Navigate to http://server-ip-address/testphp.php. It will display all the details about php such as version, build date and commands etc.

　　If you want to install all php modules at once, enter the command 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.
5. Manage MySQL Databases (Optional)
Install phpMyAdmin
　　phpMyAdmin is a free
open-source web interface tool used to manage your MySQL databases. It
is available in the Official Debian repositories. So install it with
command:
sudo apt-get install phpmyadmin　　Select the Web server that should be automatically configured to run phpMyAdmin. In my case, it is apache2.

　　The phpMyAdmin must have a database
installed and configured before it can be used. This can be optionally
handled by dbconfig-common.
　　Select ‘Yes’ to configure database for phpmyadmin wjth dbconfig-common.

　　Enter password of the database’s administrative user.

　　Enter MySQL application password for phpmyadmin:

　　Re-enter password:

　　Success! phpMyAdmin installation is installed.
　　Additional Note: if youfollowed all steps carefully, phpMyAdmin should work just fine. In casephpMyAdmin is not working, please do the following steps.
　　Open terminal, and type:
sudo nano /etc/apache2/apache2.conf　　Add the following line at the end.
Include /etc/phpmyadmin/apache.conf　　Save and Exit. Restart apache service:
　　On Ubuntu 16.04/15.10/15.04:
sudo systemctl restart apache2　　On Ubuntu 14.10 and lower versions:
sudo /etc/init.d/apache2 restart6. Access phpMyAdmin Web Console
　　Now, you can access the phpmyadmin console by navigating to http://server-ip-address/phpmyadmin/ from your browser.
　　Enter your MySQL username and password which you have given in previous steps. In my case its “root” and “ubuntu”.

　　You will be redirected to PhpMyAdmin main web interface.

　　From here, you can manage your MySQL databases from phpMyAdmin web interface.
　　That’s it. Your LAMP stack is ready to use.
