CentOS 6.4安裝OpenNebula
#安裝163源
http://mirrors.163.com/.help/CentOS6-Base-163.repo
#安裝epel源
wget http://dl.Fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
yum localinstall epel-*
#驗證查看是否安裝成功：
yum repolist
#安裝numpy(需要python-devel)
地址：http://www.scipy.org/scipylib/download.html
#解壓之後cd進入
python setup.py install
#opennebula 官網下載安裝包

cd opennebula-4.12.1-1
yum localinstall opennebula-ruby-4.12.1-1.x86_64.rpm
錯誤：
Error: Package: opennebula-ruby-4.12.1-1.x86_64 (/opennebula-ruby-4.12.1-1.x86_64)
Requires: rubygem-sqlite3-ruby
Error: Package: opennebula-ruby-4.12.1-1.x86_64 (/opennebula-ruby-4.12.1-1.x86_64)
Requires: rubygem-uuidtools

Error: Package: opennebula-ruby-4.12.1-1.x86_64 (/opennebula-ruby-4.12.1-1.x86_64)

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
解決方案：
yum install ruby ruby-devel rubygems
gem install rack
gem install sqlite3-ruby
這裡依然是各種失敗，後來發現是yum自動安裝的ruby的版本過低，重新安裝高版本ruby
yum remove ruby
https://www.ruby-lang.org/en/downloads處下載ruby
tar zxvf ruby-2.2.2-tar.gz

chkconfig iptables off

#以下數據庫設置參考
mysql -u root -p
#In mysql

上面是官網設置，我發現有問題，要按照如下設置：
GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin'@'localhost' IDENTIFIED BY 'oneadmin'
SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;
exit;
su oneadmin
one start
錯誤：

rm -I /var/lib/one/.one/sunstone_auth onegate_auth oneflow_auth occi_auth ec2_auth1
one start
sunstone-server start
錯誤：
#cannot load such file -- sinatra

sunstone-server start
錯誤：
#使用localhost:9869可以登錄，但是使用IP地址不行
vim /etc/one/sunstone-server.conf
將:host: 127.0.0.1 修改為 :host:0.0.0.0
忘記oneadmin的默認密碼
opennebula使用sha1來加密用戶密碼，所以我們使用sha1加密器加密123456並得到加密字符串，然後登錄進數據庫，在opennebula數據庫中的user_pool表中記錄了用戶的信息，而且body字段中 間的數據即為對應用戶的密碼加密字符串。
我們用得到的加密字符串來替換user_pool表中用戶名為oneadmin列的body字段中 間的數據。
然後修改/var/lib/one/.one/one_auth文件內容：oneadmin:123456
好了，這下就能用密碼123456登陸了
