Install LAMP on Ubuntu 9.10 Karmic Koala
Why install LAMP on your desktop computer?
Why would I want to install and set up a LAMP (Linux, Apache, MySQL, php) stack on Ubuntu 9.10?
It’s useful if you want to set up a private web development
environment. Perhaps you want to develop your own WordPress theme. If
you are developing websites and experimenting, it’s nice to do it in
the privacy of your own computer, rather than out on the public
The Ubuntu developers have created a very easy way to install a LAMP
server on an existing system. It’s all kicked off with this one simple
Note: Please make note of the caret (^) in the above command, it’s not a typo, it’s required to make the command work.
The apt package manager will show all the packages that need to be installed. Hit <Enter> to confirm that you want to install them.
You will then be prompted to change the password for the root user on the MySQL database.
Enter the password you want. You’ll be prompted to enter it a second time to confirm.
After you confirm your password, apt will continue to install the rest of the packages.
Congratulations, your LAMP installation is complete! That was the
easy part, now you need to get things configured to make the system
easy to work with.
Open a web browser and enter the address http://localhost/. You should see a web page that says "It Works!"
Now that you know Apache works, it’s time to test the php installation. You’ll need to create a file in /var/www called testing.php. Open a terminal and enter:
Enter the following line into the text editor, save the file and exit.
Next, restart Apache with the following terminal command.
Now go back to your web browser and enter the address http://localhost/testing.php/. You should see a page displaying version information for your php installation.
Since I’m installing LAMP for a web development environment, I want
to bind the MySQL database to the localhost IP address. This should be
127.0.0.1 for your system. You can verify it with this terminal command.
You’ll now want to verify that the correct bind address is set up in the my.cnf file.
You should see a line that looks like
bind-address = 127.0.0.1
If the IP address doesn’t match the one for your system, you’ll need to edit the my.cnf file to correct it.
You don’t need to install phpMyAdmin, but it’s a much easier way to
get in and muck around with things in your MySQL database if you’re not
familiar with the MySQL commands. You can install phpMyAdmin from the
command line with
The installation will prompt you to select a web server for
automatic configuration. Use the space bar on your keyboard to select apache2 and then hit <Enter>.
Another screen will come up asking if you want to configure a new database called dbconfig-common. Since this is a fresh installation, use the <Tab> key to select Yes and hit <Enter>.
You’ll be prompted next to enter the MySQL root password. Enter the MySQL root password that you created earlier, hit <Tab> to select Ok and hit <Enter>.
You’ll then be prompted to enter a MySQL application password for phpmyadmin. You can hit <Enter>
and a random password will be generated. I chose to use the same
password that I used for the root MySQL password. If you enter your own
password, a password confirmation screen will come up. Confirm your
The phpMyAdmin installation is now complete.
Open your web browser and enter the address http://localhost/phpmyadmin/. You should see a page like this.
You can log in with the username root and the root password that you created earlier.
Congratulations, you’re now ready to start building your local
website. If you’re only working on one site you can put all of the
files into /var/www. If you’ll be working on multiple sites you may want to consider some additional Apache configuration to keep things neat and clean on you system.
