Remote Desktop to Windows from Ubuntu 13.10

We can use Remmina Remote Desktop Client to connect to Windows remotely.
Remmina is installed by default on Ubuntu 13.10.

To open Remmina, just use Unity Dash and search for 'remmina'.

To create a new connection, just click the 'Create a new remote desktop file' (It's the second button from the left)

Then enter your connection details and click 'Connect'.

Yii migration safeUp() is not working

I tried to create a table using the safeUp() function. Here's the content of the migration file

class m140113_223038_create_test_tables extends CDbMigration
{
 public function up()
 {
 }

 public function down()
 {
 }

 public function safeUp()
 {
  $this->createTable('tbl_test',array(
   'id'=>'pk',
   'name'=>'string NOT NULL',
   ),'ENGINE=InnoDB');
 }

 public function safeDown()
 {
  $this->dropTable('tbl_test');
 }
}

However, it won't create a new table. The solution is actually very simple. If we want to use safeUp() function, we have to make sure that there's no up() function in the code. So, we have to remove both up() and down() function.

class m140113_223038_create_test_tables extends CDbMigration
{
 public function safeUp()
 {
  $this->createTable('tbl_test',array(
   'id'=>'pk',
   'name'=>'string NOT NULL',
   ),'ENGINE=InnoDB');
 }

 public function safeDown()
 {
  $this->dropTable('tbl_test');
 }
}

Yii shell is not working

I tried to run yii shell on Ubuntu 13.10 using this command:

protected/yiic shell

But it's not working. A long lines of HTML output was displayed on screen.

I found 2 solutions on the web:
1st: use this command instead:

protected/yiic shell protected/config/main.php

2nd: modify protected/config/main.php, and add this line at the top:

date_default_timezone_set('UTC')

Install phpmyadmin on Ubuntu 13.10

To install phpmyadmin, run

sudo apt-get install phpmyadmin

When I open http://localhost/phpmyadmin, it says ".../phpmyadmin/ was not found on this server".

How to fix it?
Firstly, open /etc/apache2/apache2.conf
You can open it by pressing Alt+F2, then type

gksudo gedit /etc/apache2/apache2.conf

Note: if gksudo is not installed, you can install it using "sudo apt-get install gksu".

Then go to the end of the file and type

Include /etc/phpmyadmin/apache.conf

Save the file, then restart the apache using this command

sudo /etc/init.d/apache2 restart

Done.

Install LAMP on Ubuntu 13.10

Open the terminal, then run

sudo apt-get install lamp-server^

^ sign is a Tasksel command (https://help.ubuntu.com/community/Tasksel)

Now, let's make a new php file to test.
Firstly, I'm going to open a text editor called gedit as a root user.

Press Alt + F2, then run

gksudo gedit

Note: if gksudo is not installed, you can install it using

sudo apt-get install gksu

Then type this php code

<?php
phpinfo();
?>

And save it in /var/www/ folder. I use "phpinfo.php" as the file name.
Now, open it in web browser: http:/localhost/phpinfo.php
You should be able to see the output of phpinfo().
LAMP server installation is done.
