cd  opennebula-4.12.1-1
yum localinstall opennebula-ruby-4.12.1-1.x86_64.rpm

錯誤：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
解決方式：
yum install ruby ruby-devel rubygems
gem install rack
gem install sqlite3-ruby
這裏依舊是各種失敗，後來發現是yum自己主動安裝的ruby的版本號過低。又一次安裝高版本號ruby
yum remove ruby
https://www.ruby-lang.org/en/downloads處下載ruby
tar zxvf ruby-2.2.2-tar.gz
cd ruby-2.2.2
./configure --with-openssl-dir=/usr/lib/openssl

make install

上面是官網設置。我發現有問題，要依照例如以下設置：
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：

one start
sunstone-server start

錯誤：
#cannot load such file -- sinatra

sunstone-server start

錯誤：
#使用localhost:9869能夠登錄，可是使用IP地址不行
vim /etc/one/sunstone-server.conf
將:host: 127.0.0.1 改動為 :host:0.0.0.0
#[VirtualMachinePoolInfo] User couldn‘t be authenticated, aborting call
這是由於在web頁面上改動了登錄password，可是此更新沒有同步到/var/lib/one/.one/one_auth，須要將新password寫入到該配置文件裏就可以。若該文件權限不正確則也會報錯。

忘記oneadmin的默認password
opennebula默認的password是在/var/lib/one/.one/one_auth中。

opennebula使用sha1來加密用戶password。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，並且body字段中 間的數據即為相應用戶的password加密字符串。

我們用得到的加密字符串來替換user_pool表中username為oneadmin列的body字段中 間的數據。
然後改動/var/lib/one/.one/one_auth文件內容：oneadmin:123456
好了。這下就能用password123456登陸了
