This document outlines steps to build a cloud in 4 hours using Apache CloudStack and Citrix XenServer. It discusses installing Oracle VirtualBox, Citrix XenServer, CentOS, CloudStack, and configuring MySQL, NFS, firewall rules. Key steps include downloading templates, seeding the SystemVM template, configuring zones/pods/clusters/hosts, and creating VMs to test the cloud infrastructure. Resources for further exploration are provided.

11. Apache CloudStack - Installation
1. Install minimal ISO
2. Set the hostname in /etc/hosts
3. Check output of hostname –fqdn
4. Configure CloudStack YUM repository
1. vi /etc/yum.repos.d/cloudstack.repo
2. [cloudstack]
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/rhel/4.5/
enabled=1
gpgcheck=0
5. Configure local YUM repository (optional)
1. vi /etc/yum.repos.d/lab.repo
2. [lab]
name=lab
baseurl=http://10.0.2.6/cloudstack452/
enabled=1
gpgcheck=0

12. Apache CloudStack - Installation
6. Update CentOS – yum update
7. Install supporting packages – yum insall ntp, mysql-server, httpd, wget, nfs-utils, bind-utils,
telnet
8. Install CloudStack packages – yum install cloudstack-management
9. Set the system date with NTP– ntpdate 0.centos.pool.ntp.org
10. Start and enable NTP service – service ntpd start; chkconfig ntpd on
11. Start and enable HTTPservice – service httpd start; chkconfig httpd on
12. Disable selinux – setenforce 0
13. Download and install vhd-util
1. cd /usr/share/cloudstack-common/scripts/vm/hypervisor/xenserver/
wget http://download.cloud.com.s3.amazonaws.com/tools/vhd-util
chmod 755 vhd-util
12

13. Apache CloudStack - Installation
14. Setup httpd and vm template
1. cd /var/www/html
2. wget -nc http://download.cloud.com/templates/builtin/centos56-x86_64.vhd.bz2
3. service httpd start
4. chkconfig httpd on
15. Setup MySQL
1. Edit /etc/my.cnf and add after datadir line.
2. innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = ‘ROW’
3. service mysqld start
4. chkconfig mysqld on
13

14. Apache CloudStack - Installation
16. Setup NFS shares
1. mkdir –p /export/primary
mkdir –p /export/secondary
2. Edit /etc/exports and add the following line
/export *(rw,async_no_root_squash)
3. exportfs –a
4. Edit /etc/sysconfig/nfs and uncomment the following lines
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020
MOUNTD_NFS_V3=yes
14

15. Apache CloudStack - Installation
17. Setup firewall rules
1. Edit /etc/sysconfig/iptables and add the following lines after the OUTPUT line
-A INPUT –p tcp –m tcp –m state --state NEW –m multiport --dports 111,2049,32803,892,875,662,80,8096 –j ACCEPT
-A INPUT –p udp –m udp –m state --state NEW –m multiport --dports 111,32769,892,875,662 –j ACCEPT
2. service iptables restart
18. Start the NFS services
1. service rpcbind restart
2. service nfs start
3. chkconfig rpcbind on
4. chkconfig nfs on
19. Seed the System VM template
1. mkdir –p /mnt/secondary
2. mount –t nfs –o nfsvers=3 10.0.2.211:/export/secondary /mnt/secondary
3. /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /mnt/secondary -u http://10.0.2.6/systemvm64template-4.5-xen.vhd.bz2 -h xenserver -F

16. Apache CloudStack - Installation
20. Test the NFS service from the hypervisor
21. Disable HVM check (Lab only)
20. mysql cloud –e “insert into configuration (category, instance, component, name, value, description) values (‘Advanced’, ‘DEFAULT’, ‘management-server’,
‘xen.check.hvm’, ‘false’, ‘Do we allow only the XenServers supporting HVM’);
16

17. Apache CloudStack - Configuration
Login to the UI using admin and password as credentials
Edit ‘Global Settings’ and change overprovisioning limits.
Edit ‘Global Settings’ and change allowed hosts from which templates can
be downloaded.
Restart the management server
17

18. Apache CloudStack - Configuration
Configure the zone, pod, cluster, hosts, primary and secondary storage.
18

19. Apache CloudStack
Register CentOS 5.6 template
Create the 1st VM
Create the 2nd VM
Configure Firewall, Port Forwarding, Load Balancer
19

20. Way Forward
Multiple XenServers in a cluster
Multi-Hypervisor zones
Automate installations
Load Tests
SDX – SDN, SDS
