linux server hosting

Lots of systems are set up to automatically boot from the CD / DVD drive. So you don’t need to do anything to boot Linux from a (bootable) Linux installation CD / DVD or a Linux live CD / DVD.

Linux is a open source Operating System. SO it has no license cost or any other cost, that’s why Linux VPS hosting is cheaper than Windows VPS hosting. But make sure that The choice of web server platforms should be influenced by the use to which you intend to put it. The majority of web features including PHP, MySQL, POP3 etc run fine on both Windows server as well as Linux servers.

If you want to set passwords for your computer, choosing very difficult passwords can both be advantageous or disadvantageous to you. It is advantageous because it will be hard for other people to invade your computer, to steal your files or to damage them. It can be disadvantageous to you because if you forget it, it will be very hard to remember. Hence, this will be the time that you need the assistance of Window password recovery tool. It is easy to use and very helpful. Hence, all computer users are advised to have one in their systems.

Traditionally, people wanting to burn discs on a Mac had a couple options. The first was go with what functionality is provided by the operating system itself. When considering that iTunes can burn mp3 or audio discs, iPhoto can burn images into a Photo CD, Disk Utility can burn .dmg and .iso images, and the Finder itself can burn data discs, it’s obvious that the Mac has a wealth of options built-in, but no centralized program to access all the available features.

Linux benefits small and large businesses alike. People mostly highlight the benefits it provides to the small businesses mainly because a small business does not have too much money to spend on its advertising.

Just because you run a windows desktop doesn’t mean you must opt for Windows web hosting. This is true vice versa. Whatever operating system you use on your desktop has little to do with your choice of hosts. As long as you understand your FTP or web publishing software, your host can be any operating system.

I have found a number of postings on various Linux and Ubuntu sites about using Terminal to disable IPv6 in Ubuntu. I’ve tried several of the posted solutions and found that they either didn’t work or were too complex for my simple, non-Linux Tips oriented mind to comprehend. I’ve also read that there may be a Linux kernel issue with the current version of Ubuntu in terms disabling IPv6. So I have stopped, for the moment, using Ubuntu. But fear not, I will return once I figured out a way around this.

You can run commonly used Linux software programs and also work at the Linux command line and learn how to use Linux commands – the way the real pros do Linux system administration.

(HOW-TO) LVM Virtual Server Host in Linux (CentOS 6.2)

This tutorial demonstrates step-by-step how to create a dedicated standalone LVM virtual-server host on Linux. This tutorial is geared towards advanced users with SOME linux experience but it’s not a requirement by any means. I created this tutorial in a way that anyone should be able to follow along regardless of their level of expertise.

The following items are covered in the tutorial:

– Installing CentOS 6.2 x64 (Minimal Installation).
– Setting up multiple LVMs (One for Host and one for VM).
– Installing VirtualBox 4.1 on CentOS 6.2 x64
– Importing Virtual Appliances into VirtualBox
– Accessing the Virtual Machine(s) from a client PC via SSH.
– Modifying Virtual Machines

What is a standalone LVM virtual-server host and why would I need it?

A standalone LVM virtual-server host allows you to have a dedicated box that manages all of your Virtual-Machines. This allows you to run multiple virtual machines without using your own system resources as well as keep those virtual machines running 24/7 if you choose to do so. This is also useful in a development environment as each developer can create or modify a Virtual machine and store it on a centralized server. VirtualBox transportation allows these machines to migrate while running which further improves the value of this setup.

VirtualBox is very robust and easy to use. It allows doesn’t require a high-end system to run and leaves a very small footprint. This method can be taken a step further to create your own personal cloud if a cluster is added to the equation.

LVM Partion Over-View:

vg0_host
– lv0_0_root = / (20 GB)
– lv0_1_home = /home (10 GB)
– lv0_2_swap = swap (6 GB)

vg1_vm
– lv1_0_vm (20 GB)

Commands Used:

ifconfig eth0 up
dhclient eth0
yum update
yum groupinstall “Development Tools”
yum install yum-priorities nano wget
cd /tmp
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
rpm –import http://apt.sw.be/RPM-GPG-KEY.dag.txt
rpm -i rpmforge-release-0.5.2-2.el6.rf.*.rpm
yum install dkms
fdisk /dev/sdb1

reboot
pvcreate /dev/sdb1
vgcreate -s 16M vg1_vm /dev/sdb1
lvcreate -L 20G -n lv10_vb vg1_vm
mkfs -t ext4 -m 1 -v /dev/vg1_vm/lv10_vb
mkdir “/root/VirtualBox VMs”
mount -t ext4 /dev/vg1_vm/lv10_vb /root/VirtualBox VMs/
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
yum install VirtualBox-4.1
lvm
vgs
lvs
quit
cd /root/VirtualBox VMs
wget https://t3hunderground.com/youtube/RouterOS.ova
vboxmanage import RouterOS.ova
VBoxHeadless –startvm RouterOS –vrde=off
yum install arp-scan
arp-scan –localnet
ssh admin@[IP]

(The below don’t need to be done with the RouterOS VM but can be used as reference for other VMs)

vboxmanage modifyvm RouterOS –nic1 bridge
vboxmanage modifyvm RouterOS –nic2 none
vboxmanage modifyvm RouterOS –bridgeadapter1 eth0

Other useful commands:

vboxmanage export -o NAME.ova (Exports Virtual Machine via CLI)
