Assign file permissions in jumpbox

These files were not modified through Core FTP Lite or any other ftp client i was using, so I had to login to the jumpbox as root and pass the chmod command to change permissions

sudo –i

(logs you in temporarily as root)

chmod og=rw /var/data/joomla15/xyz/abc.php

Install IONCube on Joomla Jumpbox

I spent 3-4 hours in setting up IONCube on my joomla jumpbox but there were a lot  of access issues :S

Finally here is the set of steps that lead me to its installation:

• download the ioncube loader from here:
  http://www.stevekallestad.com/wiki/IonCube_Installation
• Extract the files and copy the files to storage/joomla15/ioncube/
• Open your browser and browse to the ioncube-loader-helper.php file
• Check to see whats the status of loader file currently on your jumpbox
• We will be using php.ini setup to install the loader. php.ini is located in etc/php5/apache2/ folder.
  • Open your jumpbox and click on Alt+F1 to go to the console
  • type: sudo nano /etc/php5/apache2/php.ini
  • now add another entry in this file:
    zend_extension = /var/data/joomla15/ioncube/ioncube_loader_lin_5.2.so
  • Save this file and restart the apache server:
    sudo /etc/int.d/apache2 restart
• Now browse again to the ioncube-loader-helper.php. it should show the following screen:

Disable using Alias in the menu links

Set all the above options to NO

Joomla articles not updating

I was adding a new div in joomla articles but whenever i saved or applied the changes, all my changes reverted back and the div was lost from even the html source of the article. I spent almost 3 hours searching n trying different stuff.

The problem was that joomla articles dont allow empty divs

so:

<div class=”abc”></div>

would never show up neither be saved in the code

so i changed it to

<div class=”abc”>&nbsp;</div>

Enable remote access on Joomla Jumpbox Database

We have to enable remote access on a joomla jumpbox db in order to access it from the GUI tools which are installed on my actual machine (While jumpbox is in a VM on my actual machine)

On your VMWare player, click Alt + F1 to go to the console:

In console, write the following to get the root password:

sudo grep root /jumpbox/lib/appdata.yml

You will see a line such as the following:

root: pa$$word

where pa$$word is the password of your root user

To start using the db as the root user:

mysql -u root -p
#or
mysql -u root -ppa$$word

 

In order to allow remote access on the database, do the following:

sudo nano /etc/mysql/my.cnf

Find the bind-address property, and replace it with the IP of your jumpbox

e.g. I modified

#bind-address           = 127.0.0.1

to

#bind-address = 192.168.1.36

Restart mysql:

sudo /etc/init.d/mysql restart

Now grant all privileges to a remote db user

GRANT ALL PRIVILEGES ON *.* TO ria@'%' IDENTIFIED BY 'ria0';

where ria is the user name, and ria0 is the password of a remote user (this user need not be already existing in the db, it creates a new user if it does not exist)

Now download the GUI tools for mysql and try accessing the db using

db host: 192.168.1.36 (your jumpbox host)

user: ria

pw: ria0

I started receiving an error saying

host 'mycomputername' is not allowed to access this mysql

(I dont remember the exact error string sorry)

To solve this problem, i went back to the console and ran this command:

GRANT ALL PRIVILEGES ON *.* TO ria@'mycomputername' IDENTIFIED BY 'ria0';

(We can also use IP of the external machine instead of the computer name)

Now you will be able to access the joomla jumpbox database externally.

Using kickstart to restore a backup on jumpbox site

• Browse to kickstart.php
• choose a backup to restore from the dropdown
• choose ftp mode
  • localhost
  • port 21
  • user
  • password
  • initial directory :- /
• Click Start
• When it asks for the db access:
• Host: enter the IP of your jumpbox e.g. 192.168.1.36
• user: user which has remote access enabled on the db
• password
• database name: (I was using the db of the existing site but it was giving me could not find the database error, so i created a new empty db and gave its name here, then the restore continued)
