Customized CentOS to streamline your own exclusive Linux

Linux CentOS5.564-bit virtual machine version VmwareWorkstation9.01. add a new hard disk to linux on the virtual machine, the size is 20 GB (can be customized) 2. open the terminal and use fdisk to format and partition the newly mounted hard disk/dev/sdb,

Preface:

• CentOS 5.5 64-bit for linux

• Virtual Machine version: Vmware Workstation 9.0

1. add a new hard disk to linux on the VM, with a size of 20 GB (customizable)

2. open the terminal, use fdisk to format the partition of the new hard disk/dev/sdb that has just been attached, and divide a m primary partition and a 1g primary partition.
