Time	Narration
00:01	Welcome to the Spoken Tutorial on Common Mistakes while Installing Joomla and Uninstalling Joomla on a local server.
00:11	In this tutorial, we will learn about: common mistakes when installing Joomla, solutions to those mistakes and how to uninstall Joomla.
00:23	For this tutorial, we will be using: Ubuntu Linux 14.04, Joomla 3.4.1, Apache, MySQL and PHP obtained through XAMPP 5.5.19.
00:41	To follow this tutorial, you need to have XAMPP and Joomla installed on your system.
00:49	You also need to have knowledge of the Joomla installation process.
00:54	If not, check the relevant tutorial in the Joomla series, on the spoken tutorial website.
01:02	First of all, let me start XAMPP on my machine.
01:06	Let's open the terminal by pressing Ctrl + Alt + T keys.
01:12	Alternately, click on the “Terminal” icon in the launcher bar.
01:17	Start XAMPP by typing sudo space slash opt slash lampp slash lampp space start and press Enter.
01:28	It will prompt for administrative password.
01:31	Let me type my administrative password and press Enter.
01:36	Now we have XAMPP running.
01:39	The first mistake one can make is to extract Joomla in a different directory.
01:45	Go to the browser and open the XAMPP page by typing http colon double slash localhost and press Enter.
01:55	In the menu on the left of the screen, click on phpinfo().
02:00	Now press Ctrl +F keys and search for DOCUMENT underscore ROOT.
02:07	It will be found in the table Apache Environment.
02:11	Value of DOCUMENT underscore ROOT will be either slash opt slash lampp slash htdocs or slash var slash www.
02:24	In my machine, it is slash opt slash lampp slash htdocs.
02:30	Please note that Joomla needs to be extracted in the apache DOCUMENT underscore ROOT directory.
02:37	If this is not the case, the installation setting page would not show up at all.
02:43	Second common mistake that one can make is to have the output buffering ON.
02:49	In the 3rd step of the installation setup, output buffering should be marked as OFF.
02:55	This is a recommended setting and not a required setting.
02:59	Usually, by default, it is turned OFF.
03:03	If output buffering is ON, installation might proceed successfully.
03:08	However, the website might be extremely slow later.
03:12	In some cases, installation might hang up at this step.
03:17	In case it is ON, we can turn it OFF by editing php.ini in the apache installation.
03:24	We will go to the terminal window and locate php.ini first by typing locate space php dot ini and press Enter.
03:37	We may get a number of results for this query.
03:40	There will be one result in which php.ini will be inside the etc directory.
03:48	This directory is inside the lampp directory, inside the opt directory.
03:54	This is the one we need to edit.
03:57	In my machine, the path to that file is slash opt slash lampp slash etc slash php.ini.
04:07	We open the file in Gedit text editor by typing sudo space gedit space slash opt slash lampp slash etc slash php dot ini.
04:23	If prompted, enter your admin password.
04:27	You will have to do so whenever prompted, as we proceed.
04:32	Gedit is the default text-editor preloaded in Ubuntu Linux.
04:37	Alternately, you can use any text editor of your choice.
04:42	When the file is open, search for output underscore buffering.
04:48	The first search result we get is commented. So, we check for the next result.
04:54	Here we find the text we are looking for.
04:57	Change output underscore buffering = 4096 to output underscore buffering = off.
05:05	We save the file by pressing Control + S keys.
05:09	We can then exit the Gedit editor.
05:12	We need to restart XAMPP for the change to get reflected.
05:16	Switch to the terminal and type: sudo space slash opt slash lampp slash lampp space restart.
05:25	Press Enter.
05:27	So, we can proceed to the next step.
05:30	The third mistake you can make is to have no write permission for the configuration file.
05:36	In the last step of installation, you might get an error that says “Your configuration file or directory is not writable or there was a problem creating the configuration file”.
05:48	This occurs when we forget to give write permission to the Joomla folder.
05:53	If this error occurs, you will get some text inside a text box.
05:58	We will copy this text using Control + C keys.
06:02	In this case, we can create a new configuration.php file and paste the text into it.
06:09	We will use the touch command to create the configuration.php inside our joomla folder.
06:16	At the command prompt, type: sudo space touch space slash opt slash lampp slash htdocs slash joomla slash configuration dot php.
06:32	Press Enter.
06:34	Then type: sudo space gedit space slash opt slash lampp slash htdocs slash joomla slash configuration dot php.
06:46	Press Enter.
06:49	This will open the file in Gedit text editor.
06:52	Paste the copied text inside this file.
06:56	Check the file to make sure left bracket, question mark, php is present as the first line of the file and the content is exactly the same.
07:08	Save the configuration.php by pressing Control + S keys.
07:14	We can then exit the Gedit editor.
07:17	Now we have the configuration.php for our Joomla installation.
07:22	Now, we will see the fourth mistake that one can make during the Joomla installation.
07:27	This is to not delete the installation folder in the Finish step.
07:32	I cannot emphasize the importance of this step enough.
07:36	This is one of the most common mistakes.
07:39	So, make sure the folder is deleted.
07:42	If you get an error in this step, you must remove the folder manually.
07:47	I got an error because I am not logged-in as linux superuser and don't have delete permission.
07:56	So, now let us switch to the terminal.
07:59	We will delete the Joomla installation folder manually, from the joomla folder.
08:04	This is mandatory. So, type: cd slash opt slash lampp slash htdocs slash joomla.
08:14	Press Enter.
08:16	Then type: sudo space rm space minus rf space installation forward slash.
08:25	Press Enter.
08:27	We have now successfully installed Joomla.
08:30	We can check this by going to the browser and typing http colon double slash localhost slash joomla.
08:40	We can see our webpage.
08:43	We will now talk about uninstalling Joomla.
08:46	We need to first delete the folder into which we extracted Joomla.
08:51	So, I will switch to the terminal and type: sudo space rm space minus rf space forward slash opt slash lampp slash htdocs slash joomla slash.
09:07	Press Enter.
09:09	Now, type: cd forward slash opt slash lampp slash htdocs slash joomla.
09:17	This is to check if the folder is deleted.
09:20	As you can see, the directory does not exist.
09:24	We will then delete the database and the users.
09:28	This step will uninstall Joomla completely.
09:33	I will first go to the browser and type: http colon double slash localhost slash phpmyadmin.
09:44	I will click on the Users tab and select the user Joomla-1.
09:50	Below, there is an option- Drop the databases that have same names as the users. Click on it.
09:57	This will give you a prompt . You are about to DESTROY a complete database! Do you really want to execute DROP DATABASE? Click on OK.
10:07	Now click on GO button at the bottom right.
10:11	We have now successfully uninstalled Joomla from our localhost.
10:16	Let us summarize. In this tutorial, we learnt about: common mistakes and their solutions when installing Joomla and to uninstall Joomla.
10:28	Let's come to the assignment now.
10:30	Install Joomla. Uninstall Joomla. Check if Joomla is indeed uninstalled and install Joomla once again.
