In this section we will prepare 2 nodes for CloudStack Deploymet, one for deploying CloudStack Management Node, the second is for CloudStack Agent Node.
OS: CentOS 6.5
Mem: 3072MB(3G)
CPU: 2-Core
Disk: 100G
Network: Inner+External
We use the WolfHunterFirstNode machine, first we power down this machine, add the second ethernet card.
Power on this machine again. The newly added ethernet could not get the ip address, because we didn't set it in sysconfig, edit its configuration.
# cd /etc/sysconfig/network-scripts/
# cp ifcfg-eth0 ifcfg-eth1
# vim ifcfg-eth1
DEVICE="eth1"
BOOTPROTO="dhcp"
IPV6INIT="yes"
MTU="1500"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
# reboot
After reboot you could check eth1 is avaiable in the system, and it has the Externel network IP address assigned.
# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 52:54:00:D6:87:FA
inet addr:10.15.34.146 Bcast:10.15.34.255 Mask:255.255.255.0
Since CentOS6.5 is out-of-date, we have to use CentOS Vault repository for getting the packages, if we use the CentOS-Base, then this distribution may upgrade to CentOS6.5 automatically. We move all of the CentOS predefined repo files into another position and use our defined repo file for updating.
# mv /etc/yu.repos.d/CentOS* /root/
# vim /etc/yum.repos.d/CentOS-Vault.repo

If the download speed from vault.centos.org
is slow, you can change to http://archive.kernel.org/centos-vault/6.5/
for better speed.
Epel Repository could be imported in following:
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
CloudStack Repository should be imported like following, suppose we use version 4.5.1
of CloudStack.
# vim /etc/yum.repos.d/cloudstack.repo
[cloudstack]
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/centos7/4.5/
enabled=1
gpgcheck=0
OS: CentOS 7.1
Mem: 3072MB(3G)
CPU: 2-Core(With KVM acceleration enabled)
Disk: 100G
Network: Inner+External
CloudStack Agent Node runs on CentOS7.1, thus we created a new kvm machine, as we described in chapter 2( 2.4 Deploy Your First Node).
This node need the CPU support kvm acceleration, so when creating the kvm machine, we setup the CPU parameter like following.
In PXE menu, select CentOS7.1 related item:
Press enter and waiting for installation finished.
The network info could be viewed via:
# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

There won't be some special configuration, cause we added the hardware at the very beginning, the system has setup the address automatically.
Since CentOS7.1 is the newest version, we needn't setup the repository. But we also have to setup the epel repository and cloudstack repository.
Epel Repository:
# yum install -y wget vim
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
CloudStack Repository:
# vim /etc/yum.repos.d/cloudstack.repo
[cloudstack]
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/centos7/4.5/
enabled=1
gpgcheck=0
Verify your repo configuration via:
# yum makecache
# yum search cloudstack
By now we have setup the 2 nodes which are ready for deploying CloudStack components. In following sections we will begin to deploy components in these 2 nodes.
