LAMP on Ubuntu

LAMP Configuration on Ubuntu

A LAMP (Linux, Apache, MySQL, PHP) stack is a common web stack used for hosting web content.

This guide shows you how to install a LAMP stack on an Ubuntu 14.04 (LTS) server.

Before you begin update your system  -

# sudo apt-get update && sudo apt-get upgrade

 

Apache

Install and Configure

sudo apt-get install apache2

Configure Virtual Hosts

There are several different ways to set up virtual hosts; however, below is the recommended method. By default, Apache listens on all IP addresses available to it.

1. Within the /etc/apache2/sites-available/ directory, create a configuration file for your website, example.com.conf, replacing example.com with your own domain information:
   

    

   vim /etc/apache2/sites-available/example.com.conf

   <VirtualHost *:80>    ServerAdmin webmaster@example.com ServerName example.com ServerAlias www.example.com DocumentRoot /var/www/html/example.com/public_html/ ErrorLog /var/www/html/example.com/logs/error.log CustomLog /var/www/html/example.com/logs/access.log combined    <Directory /var/www/html/> Require all granted </Directory>   </VirtualHost>

   The ErrorLog and CustomLog entries are suggested for more fine-grained logging, but are not required. If they are defined (as shown above), the logs directories must be created before you restart Apache.

2. Create the above-referenced directories:
   

   sudo mkdir -p /var/www/html/example.com/public_html  sudo mkdir /var/www/html/example.com/logs

3. Link your virtual host file from the sites-available directory to the sites-enabled directory:
   

   sudo a2ensite example.com.conf

   
   If you later need to disable your website, run:
   

    sudo a2dissite example.com.conf

   
   
4. Reload Apache:
   
   

   sudo service apache2 reload

   
   Assuming that you have configured the DNS for your domain to point to your Linode’s IP address, virtual hosting for your domain should now work.
   If there are additional websites you wish to add to your Linode repeat the above steps to add them.
   

MySQL

Install and Configure

1. Install the mysql-server package:
   

   sudo apt-get install mysql-server

   Choose a secure password when prompted.
   
2. Run mysql_secure_installation, a program that helps secure MySQL. You will be presented with the opportunity to change the MySQL root password, remove anonymous user accounts, disable root logins outside of localhost, and remove test databases:
   

   mysql_secure_installation

Create a MySQL Database

1. Log into MySQL:
   
   

   mysql -uroot -p 

   Enter MySQL’s root password, and you’ll be presented with a MySQL prompt.
   
   
2.  Create a database and a user with permissions for it. In this example the databse is called webdata, the user webuser and password password:
   

   create database webdata;  grant all on webdata.* to 'webuser' identified by 'password';

3. Exit MySQL:
   

   quit

PHP

1. Install PHP, and the PHP Extension and Application Repository:
   

   sudo apt-get install php5 php-pear php5-mysql
2. Once PHP5 is installed, tune the configuration file located in /etc/php5/apache2/php.ini to enable more descriptive errors, logging, and better performance. The following modifications provide a good starting point:
   

   /etc/php5/apache2/php.ini

    

   error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
    

   error_log = /var/log/php/error.log
    

   max_input_time = 30
    

   Ensure the lines above are uncommented. Commented lines begin with a semicolon (;).
3. Create the log directory for PHP and give the Apache user ownership:
   
   

   sudo mkdir /var/log/php
    

   sudo chown www-data /var/log/php

   
   
4. Reload Apache:
   
   

        sudo service apache2 reload

   
   

Congratulations! You have now set up and configured a LAMP stack. Now you can put your php script in /var/www/html/ folder and run http://example.com/
