Cloning your Joomla 3.x site

I discovered a great extension which can clone or backup your Joomla 3.x site.

It is called Akeeba Backup and the extension is found here.

Just upload it to your existing Joomla 3.x site and you can then access it through Components on your admin site.

If you make a copy of your, for example, development site you can easily transfer the jpa-backupfile to your new site. Just upload this file to the root of your webserver installationfolder, for example /var/www on a apache webserver. You also have to transer a few files which are included in Akeeba Kickstart found here. Just place the required files from the kickstart-zipfile at the same folderlevel as the jpa-file.

Good luck!

Removing existing Joomla installation on Raspberry Pi

Remove all folders insida /var/www.

And use the command:

sudo apt-get remove --purge mysql\*

to delete anything related to packages named mysql. Those commands is only valid on debian / debian based linux distributions (for eg. Raspian).

For more cleanup for package cache you can:

sudo apt-get clean

Remember to:

sudo updatedb

Otherwise the "locate" command will display old data.

Install Joomla on Raspberry Pi

Joomla is a content managment system (CMS) used my many people around the globe to manage their web sites.

Step 1. Setting up the Raspberry with LAMP

If you havent yet set up your Raspberry Pi as a web server my earlier article can help you:

LAMP with Raspberry Pi

Step 2. Download and transfer files

Next, we need a copy of Joomla. ALWAYS use the latest available – you can get it from here:

http://www.joomla.org/download.html

once downloaded, you need to unpack it to the directory /var/www on your Raspberry Pi

I usually use Filezilla to transfer files from my Windows PC to my Raspberry Pi.

To extract locally, open a terminal window and type (change 'joomla.zip' below to the appropiate filename):

sudo unzip joomla.zip -d /var/www

Remove the zip-file with

sudo rm joomla.zip

You can also download an quickstart package from one of the companies who makes templates for Joomla. Just use the quickstart package instead of the above package.

Step 3. Edit config files

Now we need to change a couple of settings in your php.ini file to reduce the load on the Raspberry Pi:

cd /etc/php5/apache2
sudo nano php.ini

then press CTRL w to search for a string, and search for output_buffering

now change it to look like this:

output buffering
Default Vaule: Off
Development Value: 0
Production Value: 0b

now press CTRL o then CTRL x to save the file and exit.

Next, we need to create and make sure your configuration.php is writeable:

sudo bash
cd /var/www
touch configuration.php
chmod 777 configuration.php

and make apache owner of the www-directory

cd /var
sudo chown -R www-data:www-data www

Step 4. Install Joomla

Once done, point your browser at http://your-raspberrypi-ip/ or http://localhost if you are on the device.

(if you get the standard Apache welcome screen, delete the index.html from /var/www)

You should get the Joomla installation screen.

Just go through all the steps.

If you cant remove the installationdirectory you have to remove it by:

cd /var/www
sudo rm -rf installation

Now you are done and you can reach your website at http://your-raspberrypi-ip/ or http://localhost if you are on the device. Your adminpages are on http://your-raspberrypi-ip/administrator or http://localhost/administrator if you are on the device

 

 

Install Jenkins on a Linux Debian system

To install Jenkins on a Linux Debian system follow this guide

Step 1. Installing OpenJDK 7

To install OpenJDK 7 JRE and JDK, execute the following command:

sudo apt-get install openjdk-7-jre 
sudo apt-get install openjdk-7-jdk

Step 2. Installing Jenkins

Before we can install Jenkins, we have to add the key and source list to apt. This is done in 2 steps, first we'll add the key.

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | apt-key add -

Secondly, we'll create a sources list for Jenkins.

echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list

Now, we only have to update apt's cache before we can install Jenkins.

apt-get update

As the cache has been updated we can proceed installing Jenkins. Note that Jenkins has a big bunch of dependencies, so it might take a few moments to install them all.

apt-get install jenkins

Step 3. Configuring Jenkins

Now that Jenkins is running, go to your-server-ip-address:8080. You'll be welcomed by the default Jenkins screen.

You probably have to wait for some time to let Jenkins install itself.

 

After a while you'll be welcomed by the default Jenkins screen. Currently, the installation is insecure and everyone can access it. Lets fix that! First, go to Manage Jenkins (in the left menu) then click Setup Security on the page loaded.

Then enable the security by checking the box.

Set it to use Jenkins's own user database and disable sign ups.

Next, go for the Matrix-based security.

Make sure Anonymous only has the Read right under the View group (Jenkins could crash when it doesn't have that set).

Click save at the bottom of the page. After the page load, you'll see a login form, ignore that, go to ci.company.net:8080 again instead. You'll see this sign up form.

Sign up with a username and you'll be administrator of this fresh Jenkins install.

 

All done!

Install Phabricator on a Linux Debian system

After experiencing a few problems installing Phabricator on my Raspberry Pi I wrote this article.

"Phabricator, an open source, software engineering platform

Phabricator is a collection of open source web applications that help software companies build better software."

Requirements

Phabricator can run in a normal computer, with following required packages. We don’t need specification with high resources.

  1. Apache2.2.7 or higher
  2. MySQL and PHP 5.2 or higher
  3. Git and some of the php extensions.

You can follow my guide "Installing LAMP on a Raspberry Pi" here.

Login on the Raspberry Pi as root.

 

Step 1: Installing Required Components

We will first install a few additional PHP-extensions:

sudo apt-get install php5-gd php5-dev php5-curl php-apc
 

Step 2: Downloading Phabricator Files

Once, you have all the above stuff installed, now pick install directory. Here I’m going to create a directory called ‘myproject‘ under DocumentRoot of Apache directory.

sudo mkdir /var/www/myproject
cd /var/www/myproject

Now, start pulling the phabricator and its dependencies from there official git repository.

git clone https://github.com/phacility/libphutil.git 
git clone https://github.com/phacility/arcanist.git 
git clone https://github.com/phacility/phabricator.git

Step 3: Configure Apache for Phabricator

On Ubuntu based distributions, you need to enable mod_php, mod_rewrite and mod_ssl modules, during installation most of these modules enabled by default, but we need to confirm.

sudo a2enmod rewrite 
sudo a2enmod ssl

Once, these modules enabled, next restart the web server to reflect changes.

sudo service apache2 restart

Next, create a separate Virtualhost in your Apache configuration file.

sudo nano /etc/apache2/sites-available/phabricator.conf

Append the following Virtualhost entry at the bottom of the file and change the

DocumentRoot path to match exact location of phabricator files and ServerName path to your local ip-address

<VirtualHost *:80>
ServerName 'your local ip-address' DocumentRoot /var/www/myproject/phabricator/webroot RewriteEngine on RewriteRule ^/rsrc/(.*) - [L,QSA] RewriteRule ^/favicon.ico - [L,QSA] RewriteRule ^(.*)$ /index.php?__path__=$1 [B,L,QSA] <Directory "/var/www/myproject/phabricator/webroot"> Order allow,deny Allow from all </Directory> </VirtualHost>

You need to enable the newly created virtualhost entry using following command

sudo a2ensite phabricator.conf

Finally, restart the Apache service to reflect new changes.

sudo service apache2 restart

 

Step 4: Configure MySQL for Phabricator

Now, it’s time to configure MySQL, but before heading up for setup, make sure your MySQL is running and you able to connect to it. So, that you can load the mysql settings into it. Note that you hace to substitute 'secret' with our choosen password for the MySQL-server

cd /var/www/myproject/phabricator/
./bin/config set mysql.host localhost
./bin/config set mysql.user root
./bin/config set mysql.pass 'secret'

Next, run the storage upgrade script to load database schema into it. While processing, it will prompt you to press ‘y‘ to continue, this will take little time to complete the setup for setting-up data schema.

./bin/storage upgrade --user root --password 'secret'

Once, scheme added to mysql, restart the service to take new settings.

service mysql restart

 

Step 5: Configuring Phabricator Web UI

Now you can access the web UI at the following locations, but we need to create an admin login account.

http://ipaddress

If the above admin setup page is not displayed we need to create admin login manually from the terminal. This step only required, if incase we get the error cause admin account was not defined.

./bin/accountadmin

Once admin account created, you can login into admin section using same credentials. After login you can see some setup issue in the top left corner, that needs to be resolved before start using it.

 

All done!
