Install JDK Browse to and I have to also set JAVA_HOME to point to the jdk so I select the relevant link. In this case .I wanted a .bin le look for the .batch_prole le and edit it. And add for fedora 12 so I selected it under the Linux headingthe entry export JAVA_HOME=/usr/java/jdk1.6.0_21. Save and then logout and then login. Got the url path (right-click select properties) and in the terminal I entered the command sudo wget ensure that the path is correct by running This then download the .bin le to the directory I wasecho $JAVA_HOME in. and it returns the correct location. Then launch JBoss without any errors!!!! I then changed the permissions on the le using chmod a+x to make it executable. I the ran the le and it installed to a java folder I had created in /usr/bin/. When I do an ls it shows me the JDK folder. martes 17 de agosto de 2010 5.

How to create a virtualmachine hostPrerequisites: To check if KVM has successfully been installed,runvirshYou need kvm up and running It should display something like this: virsh # net-list --all If you don't want to run as root, the user you want to useneeds to have rw access to /dev/kvm If it displays an error instead, then something wentwrong.If you want to be able to access the internet or a local Next we need to set up a network bridge on ournetwork, your host system must be able to access theserver so that our virtual machines can beinternet or the local network accessed from other hosts as if they were physicalsystems in the network. To install KVM and virtinst (a tool to create virtual To do this, we install the package bridge-utils...yum install bridge-utilsmachines), we runyum install kvm qemu libvirt python-virtinst qemu-kvm ... and congure a bridge.Then start the libvirtdaemon:/etc/init.d/libvirtd start martes 17 de agosto de 2010 7.

Linux stores the names of all known disk partitions in the /proc/partitions le. The entire hard disk is represented by an entry with a minor number of 0, and The rst Linux step in adding a new disk is to partition it in all the partitions on the drive are sequentially preparation of adding a lesystem to it. Type the fdisk command numbered after that. followed by the name of the disk.You want to run fdisk on the /dev/sdb disk, so the command is: root@test02:~# fdisk /dev/sdb root@test02:~# cat /proc/partitions The number of cylinders for this disk is set to 9726. major minor #blocks name There is nothing wrong with that, but this is larger than 1024, 8078125000 sda and could in certain setups cause problems with: 8177875056 sda1 82 1 sda2 1) software that runs at boot time (e.g., old versions of LILO) 85 248976 sda5 2) booting and partitioning software from other OSs 8 1678125000 sdb 8 17 1 sdb1 (e.g., DOS FDISK, OS/2 FDISK) 8 21 96327 sdb5 8 22 4393746 sdb6 8 2373633896 sdb7 252074616832 dm-0 2521 3211264 dm-1 martes 17 de agosto de 2010 12. Just to make sure you're on the correct device, issuethe p command to print all the known partitions onthe disk. In this case, there are none which is good.Command (m for help): p The fdisk m command prints a small help manual of validcommands.You will see that n is the command to add a newpartition. Add a new primary partition, number 1, and use thedefaults to make the partition occupy the entire disk.
