Method 1

Centos version 6.4 has provided a packaged opennebula in the centos library. The current version is 3.8.1.

1. Install CentOS-testing repository

# cd /etc/yum.repos.d# curl -O http://dev.centos.org/centos/6/opennebula/opennebula-testing.repo

# yum repolist

2. Install the opennebula package

Front-End server Installation: opennebula-server opennebula-sunstone

Node installation: opennebula-node-kvm

I used a machine as both a front-end server and a working node.

yum install opennebula-server opennebula-sunstone opennebula-node-kvm

3. Set the network

$ Brctl show

Bridge name bridge id STPenabled interfaces

Br0 8000.000000000000 no eth0

Reference: http://opennebula.org/documentation:rel4.2:plan#networking

Bridge setting reference: http://wiki.dzsc.com/info/8659.html http://hi.baidu.com/renchunyun/item/cc0dbb1d8799e9797b5f25c6

If the centos 6.4 bridge fails to be set, the following error is returned:
Original Nic eth0: Connection activation failed: Master connection not found or invalid
Bridge Nic br0: Conncetion activation failed: Failed to determine connection's virtual interface name

The reason is that NetworkManager takes over the network. solution:

chkconfig NetworkManager offchkconfig –levels 35 network on/etc/init.d/NetworkManager stop/etc/init.d/network restart

4. Configure NFS

If you only use one machine as the front-end host and node, you can skip this step.

5. Configure ssh password-free Login

su - oneadmin ssh-keygen –t dsa   cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

Chmod600 ~ /. Ssh/authorized_keys

Add the following content~ /. Ssh/config

    Host *        StrictHostKeyChecking no        UserKnownHostsFile /dev/null

Copy~ /. SshTo all work nodes: (this part is omitted if only one machine is used)

    scp -r ~/.ssh node1:    scp -r ~/.ssh node2:...

Use oneadmin to test whether ssh localhost is successful

I have created a user and set it to log on to localhost. The reason is that selinux is on, because the home of oneadmin is under/var/lib/one and not under/home/, selinux is blocked and selinux is disabled. This official document is not clear, and I have been checking the cause for two days.

6. Start the service

    $ service opennebula start    $service opennebula-sunstone start    $service opennebula-occi start

7. log on to the system

Http: // 10.1.81.20.: 9869/
Cat/var/lib/one/. one/one_auth check the login name and password

Add host

 $ onehost create localhost -i im_kvm -v vmm_kvm -n dummy

If it fails, view the log/var/log/one/oned. log.

If you log on to this address from another IP address, you need to modify sunstone remote login, modify etc/one/sunstone-server.conf

: Host: 0.0.0.0

You can.

Method 2

You can download the rpm package from the official website to install the new version.

1. Install the epel Source

# yum install wget# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm# rpm -ivh epel-release-6-8.noarch.rpm# yum update

2. Download and install

Download Page: http://downloads.opennebula.org/

Download 4.2.0 CentOS 6 tarball

tar xvf CentOS-6-opennebula-4.2.0-1.tar.gz cd opennebula-4.2.0-1/  yum localinstall opennebula-common-4.2.0-1.x86_64.rpm   yum localinstall opennebula-ruby-4.2.0-1.x86_64.rpm   yum localinstall opennebula-4.2.0-1.x86_64.rpm   yum localinstall opennebula-sunstone-4.2.0-1.x86_64.rpm   yum localinstall opennebula-server-4.2.0-1.x86_64.rpm 

Install kvm and opennebula-node-kvm on the computing node:

yum install qemu-kvm qemu-kvm-tools libvirtyum localinstall opennebula-node-kvm-4.2.0-1.x86_64.rpm 

Enable the service:

/etc/init.d/libvirtd start  206  service opennebula start  207  chkconfig opennebula on  208  service opennebula-sunstone start  209  chkconfig opennebula-sunstone on

Open the browser and access the http: // 10.1.81.20.: 9869 logon interface. What is the login user name and password? The username and password have been randomly generated during installation. oneadmin is the username, followed by the password

# cat /var/lib/one/.one/one_auth
