| 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 the 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 |
| 02:14 | 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 slash |
| 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. |
