1. Framework of the experiment environment: (1) Management node (opennebula node) OS: Ubuntu12.04-amd64IP

1. Framework of the experiment environment:
(1) Management node (opennebula node)
OS: Ubuntu 12.04-amd64 IP: 192.168.0.11
(2) computing nodes (VM deployment nodes)
OS: ubuntu 12.04-amd64 IP: 192.168.0.12
(3) This document also describes how to use the current node as a management node and a computing node!

16. Bridge_maxage 12
    
17. Bridge_stp off

Restart NIC:

1. Sudo/Etc/Init.D/Networking restart

(2) opennebula installation and configuration

1. Sudo mkdir-P/Var/Lib// * Create the opennebula installation directory */
   

1. Sudo groupadd-G 10000 oneadmin/* Create oneadmin Group */
   

Create a oneadmin user.-d: Specifies the Home Directory of the user.-s: Specifies the shell used by the user after logon.-g: Specifies the group of the user.

1. Sudo useradd-U 10000-M oneadmin-D/Var/Lib/One-S/Bin/Bash-G oneadmin

Set password for oneadmin user

1. Sudo passwd oneadmin

Set the owner and user of the oneadmin user's home directory

1. Sudo chown-R oneadmin:Oneadmin/Var/Lib/One

Test whether the oneadmin user can log on correctly.

1. Su-L oneadmin

If yes, enter the exit command to exit!

The NFS server can be installed to specify the imgfile transmission mode through nfs.

1. Sudo apt-Get install nfs-Kernel-Server

Modify the/etc/ioports file and add the following content (meaning: 192 .168 .0 .0 /Hosts within 24 can access the/var/lib/one directory according to the requirements in brackets, or *, indicating all ip addresses in this network segment ):

1. /Var/Lib/One192.168.0.0/24(Rw,Sync,No_subtree_check,No_root_squash,Anonuid=10000,Anongid=10000)

Restart the NFS service

1. Sudo/Etc/Init.D/Nfs-Kernel-Server start

Switch to the oneadmin user and install required software

1. Su-L oneadmin
   
2. Sudo apt-Get install libsqlite3-Dev libxmlrpc-C3-Dev g++Ruby libopenssl-Ruby libssl-Dev ruby-Dev
   
3. Sudo apt-Get install libxml2-Dev libmysqlclient-Dev libmysql++-Dev libsqlite3-Ruby libexpat1-Dev
   
4. Sudo apt-Get install rake rubygems libxml-Parser-Ruby1.8 lib1_t1-Dev genisoimage scons
   
5. Sudo gem install nokogiri rake xmlparser
   
6. Sudo apt-Get install mysql-Server

Configure the mysql database and run the following command:

1. Mysql-U root-P
   
2. CREATE USER'Oneadmin'@'Localhost'IDENTIFIED'Oneadmin';
   
3. Create database opennebula;
   
4. Grant all privileges on opennebula.*TO'Oneadmin'IDENTIFIED'Oneadmin';
   
5. Quit;

Decompress opennebula and compile it:

1. Cd~/Opennebula-3.1.4
   
2. Scons sqlite=No mysql=Yes

Install opennebula:

1. ./Install.Sh-U oneadmin-G oneadmin-D/Var/Lib/One

Set environment variables related to opennebula:

1. Vim~/.Bash_profile
   
2. Export ONE_LOCATION=/Var/Lib/One
   
3. Export ONE_AUTH=$ONE_LOCATION/.One/One_auth
   
4. Export ONE_XMLRPC=Http://192.168.0.12:2633/RPC2
   
5. Export PATH=$ONE_LOCATION/Bin:/Usr/Local/Bin:/Var/Lib/Gems/1.8/Bin/:/Var/Lib/Gems/1.8/:$PATH

NOTE: If your environment is a local machine, that is, a management node and a computing node, change 192.168.0.12 to localhost.

1. Source~/.Bash_profile

Create an opennebula user authorization file:

1. Mkdir~/.One
   
2. Echo"Oneadmin: " > ~/.One/One_auth

Modify the opennebula configuration file:

1. /* Comment 58 rows */
   
2. # DB= [Backend= "Sqlite" ]
   
3. /* Modify lines 61-66 as follows */
   
4. DB= [Backend= "Mysql",
   
5. Server= "192.168.0.12",/* If the local computer is used as the computing node and the management node, change it to: localhost */
   
6. Port=0,
   
7. User= "Oneadmin",
   
8. Passwd= "Oneadmin",
   
9. Db_name= "Opennebula" ]

Start opennebula and test whether the installation is successful:

1. One start
   
2. Onevm list
   

If the following content is displayed, the installation is successful:

1. ID USER GROUP NAMESTAT CPU MEM HOSTNAME TIME
