CentOS 6.x apache cloudstack setup

For easier cloudstack setup allocate following resources or use following steps:

1. Hardware virtualization enabled host
2. CentOS 6.X fully installed on the host
3. Current host network should use static IP and avoid DHCP
4. Configure static IP using /etc/sysconfig/network-scripts without depending upon Network Manager to ensure that IP address is available on system-boot without requiring user login
5. Configure hostname in /etc/sysconfig/network. Add same in /etc/hosts. Also do "service network restart" for changes to take effect.
6. Disable SELinux
7. Configure time synchronization with a global or local NTP server
8. Configure cloudstack repository using:

   [cloudstack]
   name=cloudstack
   baseurl=http://cloudstack.apt-get.eu/centos/6/4.8/
   enabled=1
   gpgcheck=0

9. We will create both /primary and /secondary storage over NFS using:
   1. yum -y install nfs-utils
   2. mkdir /primary
   3. mkdir /secondary
   4. edit /etc/exports to have

      /secondary *(rw,async,no_root_squash,no_subtree_check)
      /primary *(rw,async,no_root_squash,no_subtree_check)

   5. edit /etc/sysconfig/nfs with following values

      LOCKD_TCPPORT=32803
      LOCKD_UDPPORT=32769
      MOUNTD_PORT=892
      RQUOTAD_PORT=875
      STATD_PORT=662
      STATD_OUTGOING_PORT=2020

   6. Configure firewall to allow incoming network connecting by appending following lines to /etc/sysconfig/iptables appropriately

      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 111 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 111 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 2049 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 32803 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 32769 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 892 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 892 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 875 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 875 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p tcp --dport 662 -j ACCEPT
      -A INPUT -s 172.16.10.0/24 -m state --state NEW -p udp --dport 662 -j ACCEPT

   7. Restart various services and enable them on startup

      service iptables restart
      service rpcbind start
      service nfs start
      chkconfig rpcbind on
      chkconfig nfs on

10. Install and configure MySQL database using:
    1. yum -y install mysql-server
    2. edit /etc/my.cnf to have

       innodb_rollback_on_timeout=1
       innodb_lock_wait_timeout=600
       max_connections=350
       log-bin=mysql-bin
       binlog-format = 'ROW'

       ;

    3. Restart and enable services using:

       service mysqld start
       chkconfig mysqld on

11. yum -y install cloudstack-management
12. cloudstack-setup-databases cloud:password@localhost --deploy-as=root
13. cloudstack-setup-management

    Note if the servlet container is Tomcat7 the argument –tomcat7 must be used.

14. Setup system template using:

    /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /secondary \
    -u http://cloudstack.apt-get.eu/systemvm/4.6/systemvm64template-4.6.0-kvm.qcow2.bz2 -h kvm -F

    Here you can also download http://cloudstack.apt-get.eu/systemvm/4.6/systemvm64template-4.6.0-kvm.qcow2.bz2 first and then give local path for setting up template

15. Setup cloud-stack agent using steps mentioned at CentOS 6.x apache cloudstack agent setup
16. You should be able to access management interface at http://<management-IP-or-FQDN>:8080/ using admin:password
17. Setup zone, example values (taken from reference links) are

    Name

    we will set this to the ever-descriptive ‘Zone1’ for our cloud.

    Public DNS 1

    we will set this to ‘8.8.8.8’ for our cloud.

    Public DNS 2

    we will set this to ‘8.8.4.4’ for our cloud.

    Internal DNS1

    we will also set this to ‘8.8.8.8’ for our cloud.

    Internal DNS2

    we will also set this to ‘8.8.4.4’ for our cloud.

18. Setup pod, example values (taken from reference links) are:

    Name

    We’ll use Pod1 for our cloud.

    Gateway

    We’ll use 172.16.10.1 as our gateway

    Netmask

    We’ll use 255.255.255.0

    Start/end reserved system IPs

    we will use 172.16.10.10-172.16.10.20

    Guest gateway

    We’ll use 172.16.10.1

    Guest netmask

    We’ll use 255.255.255.0

    Guest start/end IP

    We’ll use 172.16.10.30-172.16.10.200

19. Setup cluster, example values (taken from reference links) are:

    Name

    We’ll use Cluster1

    Hypervisor

    Choose KVM

20. Add the first host to the cloud using IP address, root username and root password
21. Configure Primary storage, example values (taken from reference links) are:

    Name

    We’ll use ‘Primary1’

    Server

    We’ll be using the IP address 172.16.10.2

    Path

    Well define /primary as the path we are using

22. Configure secondary storage, example values (taken from reference links) are:

    NFS server

    We’ll use the IP address 172.16.10.2

    Path

    We’ll use /secondary

23. Import OS/ISO and template after referring to CentOS 6.x apache cloudstack troubleshooting and deploy a few test VMs
