If you are going to host your website on Unmanaged Dedicated Server or VPS then in that case you are the one, who is going to install all the required services. You can host any PHP based dynamic website or blog like WordPress on Linux, using Apache Server, MySQL or any other Relational Database and PHP. LAMP is a acronym which is a collection of open source software which represent Linux Operating System, Apache Web Server, MySQL database and PHP. By installing these you will be able to run any PHP based dynamic website.
In this post i am going to explain How to install and configure Linux, Apache, MySQL, PHP(LAMP) stack. First thing you need is a VPS with Ubuntu 14.0 installed, you can get it from DigitalOcean they have monthly plan as low as $5. After purchasing you will get you VPS configured with Ubuntu 14.04 OS and your root user detail. Now follow my instruction for next step
How To Install Apache Web Server?
To install Apache Web Server, log in to your VPS server with root user access using any SSH client, You can use Putty for this purpose. Now we are going to install apache using apt package manager, which will download the apache setup from ubuntu repository. Enter below command in putty client
sudo apt-get update sudo apt-get install apache2
We are using sudo linux command to run the installation as root user. Few minutes after your setup will complete and control will return to prompt. To check if your Apache Server is configured correctly or not, you can visit your server ip
if everything is right, you will see the test page with message It works! . Now your Apache is running, if you ever need to start, stop or restart Apache Web server you can do by following command
Start Apache Server :
sudo /etc/init.d/apache2 start
Stop Apache Server :
sudo /etc/init.d/apache2 stop
Restart Apache Server :
sudo /etc/init.d/apache2 restart
How To Install MySQL?
After configuring Apache next step is setting up MySQL. MySQL is a open source database management system and it will store all the website data in form of relational table. MySQL requires some helper packages through which it communicates with other components. We can install these with MySQL with below command
sudo apt-get install mysql-server php5-mysql
During installation MySQL will ask you to set root password for administrative access. Set this password different from your Linux root password for security purpose.
After few minutes MySQL will be installed, now we need to setup the environment where MySQL will store its information. You can do so by running below command
To increase the security of MySQL, one extra step is recommended and that is MySQL Secure Installation and we can do that by running below interactive script.
It will ask your MySQL root password and give you option to change it or keep the existing one, you can do so by entering ‘y’ or ‘n’ in the prompt. For other question just press the ‘ENTER’ key and it will set the default values. By doing so setup will remove MySQL sample users and databases, disable remote root logins, and load the currently changed setting. With this step your MySQL is configure and ready to use.
Whenever you want to start and stop MySQL database you can do so by entering below command
Start MySQL Database :
sudo service mysql start
Stop MySQL Database :
sudo service mysql stop
How To Install PHP?
As of now we have configured a VPS system with Ubuntu 14.04, Apache Web Server and MySQL Database. Our next and last step will be to install PHP which will process all your dynamic content. To install PHP type below command on terminal
sudo apt-get install php5 libapache2-mod-php5 php5-mcrypt
Above command will install PHP with all the dependency.
Now we need to do some changes in Apache configuration to manage dynamic website. By default Apache looks for index.html in your website directory and if found then it looks for another one according hierarchy. We are going to set the default setting for .php so that web server will first search for index.php file. To modify the setting enter below command
sudo nano /etc/apache2/mods-enabled/dir.conf
Output will be like this
<IfModule mod_dir.c> DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm </IfModule>
Now change the order of files with this
<IfModule mod_dir.c> DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm </IfModule>
Now web server will processs php file first.
How To Check If PHP is Working on Web Server or Not?
We can check whether PHP is installed or not and is working properly by creating a simple info.php file. You need to create this file in your public_html directory, you can do so by entering
sudo nano /var/www/public_html/info.php
It will open nano editor, you can use vi editor instead of nano. Enter below sample php code and save the file
<?php phpinfo(); ?>
After saving the file you need to enter your server ip with info.php page, it will be like
Your screen should look like this
With this step we have now successfully configured LAMP stack on Ubuntu 14.04. Now you can install any CMS or host your dynamic website on this server. Below image represent LAMP Architecture and how this server will process dynamic content.
