[Ubuntu-BR] Instalação do Java JRE

[Reinaldo]

Pessoal, tentei instalar o Java RE da página do Java usando os comandos que eles aconselham. Mas não deu
certo porque como não sei a senha do superusuário (su), não consigo fazer o arquivo tornar executável ...

Eu até criei uma pasta /usr/java  no Ubuntu 11.10 e copiei esse arquivo para lá, mas não rolou ...

Nesse caso é necessário ter a senha do su ? Se afirmativo, como posso saber a senha ? (Como criá-la ou
modificá-la ?)


Tem algum outro jeito para instalar o java jre ?

Valeu.
Reinaldo.

Procedimento do site: http://www.java.com/en/download/help/linux_install.xml#selfextracting

To install the Linux (self-extracting) file
Follow these instructions: 
	1. Change the permission of the file you downloaded to be executable. Type:
chmod a+x jre-6u<version>-linux-i586.bin
	2. Verify that you have permission to execute the file. Type:
ls -l 

	1. Change to the directory in which you want to install. Type:
cd <directory path name>
For example, to install the software in the /usr/java/ directory, Type:
cd /usr/java/

Note about root access: To install Java in a system-wide location such as /usr/local, you must 
login as the root user to gain the necessary permissions. If you do not 
have root access, install the Java in your home directory or a 
subdirectory for which you have write permissions. 	1. Run the self-extracting binary Type:
./jre-7u<version>-linux-i586.bin

The license agreement is displayed. Review the agreement. Press the spacebar to display the next page. At the end, enter yes to proceed with the installation.


	2. Java is installed into its own directory. In this example, it is installed in the /usr/java/jre1.7.0_<version> directory. When the installation has completed, you will see the word Done.
 

	1. Verify that the jre1.7.0_<version> sub-directory is listed under the current directory.  Type:
ls 
The installation is now complete. Skip to the Enable and Configure section.
