How To Install Joomla on a linux Server Running Ubuntu


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

Shell Script: Find Number Of Arguments Passed

Many times , when we create shell scripts we try to do repetitive tasks through functions. Some functions take arguments & we have to check the no. of arguments that are passed to it.

Each bash shell function has the following set of shell variables:
[a] All function parameters or arguments can be accessed via $1, $2, $3,..., $N. [b] $* or $@ holds all parameters or arguments passed to the function. [c] $# holds the number of positional parameters passed to the function. [d] An array variable called FUNCNAME ontains the names of all shell functions currently in the execution call stack. ExampleCreate a shell script as follows: #!/bin/bash # Purpose: Demo bash function # ----------------------------- ## Define a function called test() test(){   echo "Function name:  ${FUNCNAME}"   echo "The number of positional parameter : $#"   echo "All parameters or arguments passed to the function: '$@'"   echo }
## Call or invoke the function ## ## Pass the parameters or a…

AMD Radeon™ HD 7670M on Ubuntu 12.04

Update:  Recently I install kubuntu 13.10 and there is no problem with graphics. It just works  fine out of the box.
I've seen many blog posts on how to make AMD HD7670M work on Ubuntu 12.04, specially when its in switchable graphics board like Dell Inspiron 15R 5520. I tried many things to make it work so that I could use the cinnamon desktop on ubuntu & other things too.. But to my surprise even the drivers from AMD site didn't work.
Then I tried a combination of those blog posts I read & somehow I became successful in running the full graphics including compiz settings inside My Ubuntu Machine.
Following are the steps I followed & it worked...
1. Create a backup of your xorg configuration file:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.BAK
2. Remove/purge current fglrx and fglrx-amdcccle :
sudo apt-get remove --purge fglrx*
3. Install the driver:
sudo apt-get install fglrx fglrx-amdcccle
4. Install additional components for advanced graphics:
sudo apt-get install xvba-…

CentOS / Redhat : Configure CentOS as a Software Router with two interfaces

Linux can be easily configured to share an internet connection using iptables. All you need to have is, two network interface cards as follows:
a) Your internal (LAN) network connected via eth0 with static ip address 192.168.0.1
b) Your external WAN) network is connected via eth1 with static ip address 10.10.10.1  ( public IP provided by ISP ) Please note that interface eth1 may have public IP address or IP assigned by ISP. eth1 may be connected to a dedicated DSL / ADSL / WAN / Cable router: Step # 1: Enable Packet ForwardingLogin as the root user. Open /etc/sysctl.conf file # vi /etc/sysctl.conf
Add the following line to enable packet forwarding for IPv4: net.ipv4.conf.default.forwarding=1
Save and close the file. Restart networking: # service network restart
Step # 2: Enable IP masquerading
In Linux networking, Network Address Translation (NAT) or Network Masquerading (IP Masquerading) is a technique of transceiving network traffic through a router that involves re-writing the source and/or d…
