Installing A Lamp Stack On Ubuntu Linux with Tasksel
Special Note (03/27/2015)
This entry is a bit old. It should still work, but I generally recommend everyone use Vagrant to manage their local LAMP stacks.
These are some basic instructions and notes on installing a LAMP stack on Ubuntu or Debian Linux.
Installation Using Tasksel
Perhaps the easiest method for installing a LAMP stack on Ubuntu/Debian is to use tasksel.
sudo apt-get install tasksel
Install the LAMP stack
sudo tasksel install lamp-server
At the prompt you should provide a Mysql root user password.
Test the Basic Installation
In your web browser, navigate to http://localhost. You should see the following message:
It works! This is the default web page for this server. The web server software is running but no content has been added, yet.
Where the Web Sites Are
The default web directory is in /var/www . Any other sites you set up will go in /var/www/vhosts.
The following procedure can be used to test the PHP installation:
cd /var/www sudo touch info.php sudo vim info.php # Or whatever editor you like
In the open editor add the following line and save the file.
Now go to http://localhost/info.php in your web browser. You should see the standard PHP Info page. If PHP is not working and instead asks you to download the page, reinstall libapache2-mod-php5.
How to Reinstall libapache2-mod-php5
First purge any existing copies with apt-get
sudo apt-get remove --purge libapache2-mod-php5
Now reinstall to library.
sudo apt-get install libapache2-mod-php5
Visit the test page http://localhost/info.php again. If it still isn't working, you may find more help here https://help.ubuntu.com/community/ApacheMySQLPHP .
Secure Default Mysql User Accounts
If you set a password for the mysql root user during the initial installation, then you should be good. If not, log in to mysql and remove any access users who are anonymous, not originating from an approved host, or not using a password.
Add GD Lib support
The tasksel install may not have GD installed or enabled. If so, run the following to install it.
sudo apt-get install php5-gd sudo /etc/init.d/apache2 restart
Enable Mod Rewrite
If you are doing any fancy URL rewriting, such as Drupal's Clean URL's feature, you will need to enable Mod Rewrite.
sudo a2enmod rewrite sudo /etc/init.d/apache2 restart
Install Tomcat Server
Optionally add the Java Tomcat server and mod_jk.
sudo tasksel install tomcat-server sudo apt-get install libapache2-mod-jk
