Centos6 quick installation of opennebula 3.8.1 4.2.0

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 etcyum.repos.d# curl -Ohttpdev.centos.orgcentos6opennebulaopennebula-testing.repo

# yum repolist

2. Install the opennebula package

Front-End Server Installation: opennebula-serverand opennebula-Sunstone

Node installation: opennebula-node-KVM

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

yun install opennebula-serverand 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

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 and install a new version.
