Installing LAMP on Ubuntu Jaunty (9.04)
For the latest version, check out Install LAMP on Ubuntu 9.10 Karmic Koala.
Why Install LAMP?
Today I'm going to show how to install and set up a LAMP (Linux, Apache, MySQL, PHP) stack on Ubuntu. Why do this? It's useful if you want to set up an off-line web development environment. If you are building websites and experimenting, it's nice to do it in the privacy of your own computer, rather than "in the wild" out on the internet.
Ubuntu has an easy way to select and install all of the required packages. It's done with the following command.
Don't forget to include the carrot. According to the Ubuntu documentation, it's magical.
Hit <Enter> to confirm you want to install the packages.
Next, you will be prompted to change the password for the root user on your MySQL database.
Enter your chosen password. Enter it again in the confirmation screen.
After some more chugging in the terminal the installation will complete.
Now we need to test the installation and get things configured.
Open a web browser and enter the address http://localhost/. You should see a webpage displaying the text "It Works!"
Now we're going to test our PHP installation. To do this we'll create a file called testing.php in /var/www. Open a terminal and enter:
Enter the line below, save the file, and exit the text editor.
Now we need to restart Apache.
Now, open your browser and enter http://localhost/testing.php/. You should see a bunch of information about your version of PHP.
Now we need to configure MySQL to be associated with the IP address of your machine. Since I'm installing the LAMP stack for a web development environment I'm going to bind MySQL to the localhost IP address, which in my case is 127.0.0.1. You can verify this address with:
Edit the my.cnf file to configure the bind address.
Verify that the bind-address line looks like this (adjust for your IP address).
bind-address = 127.0.0.1
This step is optional, but phpMyAdmin will make it much easier to administer the MySQL databases.
During the installation you will be prompted to select your web server for automatic configuration. Use the space bar to mark apache2 and then hit <Enter>.
You will also be asked if you want to configure phpMyAdmin with a new database called dbconfig-common. Select Yes and hit <Enter>.
Next you'll be prompted for the password for MySQL's administrator. Enter the MySQL root password that you created earlier in the installation. Hit <Tab> to select Ok and hit <Enter>.
Next you'll be prompted to create an application password for phpMyAdmin to talk to MySQL. If you leave it blank, a random password will be generated for you.
After configuring the password, the installation should complete.
Enter http://localhost/phpmyadmin/ into your web browser. You should see a page that looks like this:
You should be able to log in using the username root and the root password that you created earlier.
Your LAMP installation is now complete.
At this point you may want to do some additional Apache configuration.
