Installing LAMP On Ubuntu


Installing LAMP On Ubuntu

In this guide I will show you how to install a LAMP system. LAMP stands for Linux, Apache, MySQL, PHP. The guide is intended to help those who have very little knowlegde of using Linux.

Alternative method

sudo apt-get install tasksel

sudo tasksel


Install Apache

To start off we will install Apache.
1. Open up the Terminal (Applications > Accessories > Terminal).
2. Copy/Paste the following line of code into Terminal and then press enter:
sudo apt-get install apache2
3. The Terminal will then ask you for you're password, type it and then press enter.

Testing Apache

To make sure everything installed correctly we will now test Apache to ensure it is working properly.
1. Open up any web browser and then enter the following into the web address:
http://localhost/
You should see a folder entitled apache2-default/. Open it and you will see a message saying "It works!" , congrats to you!
echo "ServerName localhost" | sudo tee /etc/apache2/conf.d/fqdn


sudo service apache2 reload

Install PHP

In this part we will install PHP 5.
Step 1. Again open up the Terminal (Applications > Accessories > Terminal).
Step 2. Copy/Paste the following line into Terminal and press enter:
sudo apt-get install php5 libapache2-mod-php5
Step 3. In order for PHP to work and be compatible with Apache we must restart it. Type the following code in Terminal to do this:
sudo /etc/init.d/apache2 restart

Test PHP

To ensure there are no issues with PHP let's give it a quick test run.
Step 1. In the terminal copy/paste the following line:
sudo gedit /var/www/testphp.php
This will open up a file called phptest.php.
Step 2. Copy/Paste this line into the phptest file:
<?php phpinfo(); ?>
Step 3. Save and close the file.
Step 4. Now open you're web browser and type the following into the web address:
http://localhost/testphp.php
The page should look like this:

Congrats you have now installed both Apache and PHP!

Install MySQL

To finish this guide up we will install MySQL. (Note - Out of Apache and PHP, MySQL is the most difficult to set up. I will provide some great resources for anyone having trouble at the end of this guide.)
Step 1. Once again open up the amazing Terminal and then copy/paste this line:
sudo apt-get install mysql-server

Enter the password you want to use for MySQL, Do not leave it blank . You'll be prompted a second time to confirm your password.


How to remove it totally use this:


sudo apt-get remove mysql-common mysql-server
sudo apt-get --purge remove 


Step 2 (optional). In order for other computers on your network to view the server you have created, you must first edit the "Bind Address". Begin by opening up Terminal to edit the my.cnf file.
sudo gedit /etc/mysql/my.cnf
Change the line
bind-address = 127.0.0.1
And change the 127.0.0.1 to your IP address.
Step 3. (optional) This is where things may start to get tricky. Begin by typing the following into Terminal:
mysql -u root
Following that copy/paste this line:
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yourpassword');
(Make sure to change yourpassword to a password of your choice.)
Step 4. We are now going to install a program called phpMyAdmin which is an easy tool to edit your databases. Copy/paste the following line into Terminal:
sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin
After that is installed our next task is to get PHP to work with MySQL. To do this we will need to open a file entitled php.ini. To open it type the following:
sudo gedit /etc/php5/apache2/php.ini
Now we are going to have to uncomment the following line by taking out the semicolon (;).
Change this line:
;extension=mysql.so
To look like this:
extension=mysql.so
Now just restart Apache and you are all set!
sudo /etc/init.d/apache2 restart

Known Issues:

Symolic link to  var/www folder is not working

Forbidden

You don't have permission to access *** on this server.

Apache/2.2.22 (Ubuntu) Server at localhost Port 80



sometimes its happening if:
your source folder are on ntfs file system, or if you using already created folder, witch have different chmod, probably from previous owner or installation. I sorted out this problem by creating new folder in ext4 file system and made symbolic link to /var/www folder.


The End

Quick note to anyone who encountered problems with setting up the MySQL password, please refer to this page: MysqlPasswordReset
I applaud everyone who has taken the time to read this guide. This guide is also my first ever so I would love to hear back from the public on what you guys think! Just don't be too harsh. ;)
