1. What is Proxmox?
Proxmox is an Open Source Server Virtualization Platform, based on KVM and OpenVZ.
2. Installation
Go to proxmox web site and download the the latest version at: http://www.proxmox.com/downloads
and install,
In this example my harddis size to install Promox is just only 55GB. and I will configure Raid 5 to store the Virtual Private Servers (VPSs) and VPSs Backup in the following steps.
Follow the installations step and fill in by your own information:
Enter to Boot: _
I agree
Next

Wait,

Reboot, to finish the installation.
We can log in with user "root" with the password that we put during the installation.
Or we can access via web browser with user "root" with the password that we put during the installation.
3. Promox Usage
Proxmox system file and path:
Proxmox has 3 main default configuration paths:
/etc/pve/
It is the important path for global Proxmox configuration such as VMs list, Storage information, Users, etc.
/etc/vz/
It is mainly for the Proxmox repository where we can define the download repository, logs path, log level etc.
/var/lib/vz
It is the default storage where we can store the IOS, images, dumps and as well as the VPSs. We are currently point all these images and VMs to /storage partition.
4. VPSs Storage
4.1 Create a Raid storage for VPSs and backup
In this example, I am going to configure RAID5 with 50GB with 3 Disks.
Install required softwares:
apt-get update
apt-get install vim
apt-get install mdadm
Now I am going to setup RAID5 on /dev/sdb /dev/sdc /dev/sdd
root@proxmox01:~# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x98a71f64.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
root@proxmox01:~#
and then do the same for other disks (/dev/sdc and /dev/sdd)
RAID-5:
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1
root@proxmox01:~#mkfs.ext4 /dev/md0
root@proxmox01:~# mkdir /storage
root@proxmox01:~# mount /dev/md0 /storage/
Now we should see /storage with the size (50GB * 3) - 50GB = 100GB
Add to fstab file
vi /etc/fstab
Create tother 3 folders under /storage
mkdir /storage/proxmox_sys
mkdir /storage/proxmox_data
mkdir /storage/proxmox_backup
Changing default Proxmox configuration and storage path
cd /etc/vz/
vi vz.conf
Change following
LOCKDIR=/storage/proxmox_sys/lib/vz/lock
DUMPDIR=/storage/proxmox_sys/lib/vz/dump
LOGFILE=/storage/proxmox_sys/log/vzctl.log
TEMPLATE=/storage/proxmox_sys/lib/vz/template
VE_ROOT=/storage/proxmox_sys/lib/vz/root/$VEID
VE_PRIVATE=/storage/proxmox_sys/lib/vz/private/$VEID
Go to -> Data Center -> Storage -> Add -> Directory -> Select (ISO,Images,Containers and Templates) and named the Directory as proxmox_data
Go to -> Data Center -> Storage -> Add -> Directory -> Select (Backups) and named the Directory as proxmox_backup
and all the other required folders will be create automatically in these folders.
Copy the image iso for the distribution that you want to install and put in the correct location.
Example, we want to install a Ubuntu server, so we just copy the image iso of Ubuntu server put in: /storage/proxmox_data/template/iso
So when we create the VPSs we can select the default location or we want to use the path /storage which is the RAID-5 we create.
Here We go, Enjoy.
Error:
Go to -> Option -> KVM hardware virtualization -> Untick -> OK
That all for now about this Virtualize environments that I want to mention...!
I am going to test more with the Cluster and Move a VPSs without downtime. ;) for the next post.
