Hello!
My Spanish is quite bad, but it sounds like you got Spark installed\unpacked OK, but are having trouble running it?
I think under linux you will need to locate your installation directory (or wherever you unpacked the tar.gz file to) and execute the shell script that starts everything up.
so like this:
[user@pc]# cd /path/to/your/spark/directory
[user@pc]# ./Spark
This should launch Spark for you.
