About Joomla
Joomla is a free and open source content
management that uses a PHP and a backend database, such as MySQL. It offers a
wide variety of features that make it an incredibly flexible content management
system right out of the box. It was created in 2005 and is currently the 2nd
most popular content management site online. It now has over 10,000 addons to
customize its functionality.
Setup
The steps in this tutorial require the user to
have root privileges on their linux server. You can see how to set that up in
steps 3 and 4 of the Initial Server Setup
Before
working with Joomla, you need to have LAMP installed on your linux server. If
you don't have the Linux, Apache, MySQL, PHP stack on your linux server, you
can find the tutorial for setting it up here: How to Install LAMP on Ubuntu.
Once
you have the user and required software, you can start installing Joomla!
Step One—Download Joomla
To start, create a directory where you will keep
your Joomla files temporarily:
# mkdir temp
Switch
into the directory:
# cd temp
Then
you can go ahead and download the most recent version of Joomla straight from
their website.
Currently, the latest version is 2.5.7.
# wget http://joomlacode.org/gf/download/frsrelease/17410/76021/Joomla_2.5.7-Stable-Full_Package.tar.gz
This
command will download the zipped Joomla package straight to your user's home
directory on the linux server. You can untar it with the following command,
moving it straight into the default apache directory, /var/www :
# sudo tar zxvf Joomla_2.5.7-Stable-Full_Package.tar.gz -C /var/www
Step Two—Configure the Settings
Once the Joomla files are in the web directory, we
alter a couple of permissions to give access to the Joomla installer. First
create a Joomla configuration file and make it temporarily world-writeable:
# sudo touch /var/www/configuration.php
# sudo chmod 777 /var/www/configuration.php
After
the installation is complete, we will change the permissions back down to 755,
which will make it only writeable by the owner.
Step Three—Create the Joomla Database and
User
Now we need to switch gears for a moment and
create a new MySQL directory for Joomla.
Go
ahead and log into the MySQL Shell:
# mysql -u root -p
Login
using your MySQL root password. We then need to create the Joomla database, a
user in that database, and give that user a new password. Keep in mind that all
MySQL commands must end with semi-colon.
First,
let's make the database (I'm calling mine Joomla for simplicity's sake—for a
real server, however, this name is not very secure). Feel free to give it
whatever name you choose:
CREATE DATABASE joomla;
Query OK, 1 row affected (0.00 sec)
Then
we need to create the new user. You can replace the database, name, and
password, with whatever you prefer:
CREATE USER juser@localhost;
Query OK, 0 rows affected (0.00 sec)
Set
the password for your new user:
SET PASSWORD FOR juser@localhost= PASSWORD("password");
Query OK, 0 rows affected (0.00 sec)
Finish
up by granting all privileges to the new user. Without this command, the Joomla
installer will be able to harness the new mysql user to create the required
tables:
GRANT ALL PRIVILEGES ON joomla.* TO juser@localhost IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)
Then
refresh MySQL:
FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
Exit
out of the MySQL shell:
exit
Restart
apache:
# sudo service apache2 restart
Step Four—Access the Joomla Installer
Once you have placed the Joomla files in the
correct location on your linux server, assigned the proper permissions, and set
up the MySQL database and username, you can complete the remaining steps in
your browser.
Access
the Joomla installer going to your domain name or IP address. (eg. Example.com)
Once
you have finished going through the installer, delete the installation folder
per Joomla’s instructions and change the permissions on the config file:
# sudo rm -rf /var/www/installation/
# sudo chmod 755 /var/www/configuration.php
Visit
your domain or IP address to see your new Joomla page
