#安装epel源
wget http://dl.Fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
yum localinstall epel-*
#验证查看是否安装成功：
yum repolist
#安装numpy(需要python-devel)

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

错误：
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

解决方案：
yum install ruby ruby-devel rubygems
gem install rack
gem install sqlite3-ruby
这里依然是各种失败，后来发现是yum自动安装的ruby的版本过低，重新安装高版本ruby
yum remove ruby
https://www.ruby-lang.org/en/downloads处下载ruby
tar zxvf ruby-2.2.2-tar.gz
cd ruby-2.2.2
./configure --with-openssl-dir=/usr/lib/openssl

make
make install

上面是官网设置，我发现有问题，要按照如下设置：
GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin'@'localhost' IDENTIFIED BY 'oneadmin'
SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;
exit;

su oneadmin
one start

错误：
#Oned failed to start /usr/bin/one:line 117 14118 Terminated

one start
sunstone-server start

错误：
#cannot load such file -- sinatra
gem install sinatra
#cannot load such file -- builder
gem install builder1
sunstone-server start

错误：
#使用localhost:9869可以登录，但是使用IP地址不行
vim /etc/one/sunstone-server.conf
将:host: 127.0.0.1 修改为 :host:0.0.0.0

忘记oneadmin的默认密码
opennebula使用sha1来加密用户密码，所以我们使用sha1加密器加密123456并得到加密字符串，然后登录进数据库，在opennebula数据库中的user_pool表中记录了用户的信息，而且body字段中 间的数据即为对应用户的密码加密字符串。
我们用得到的加密字符串来替换user_pool表中用户名为oneadmin列的body字段中 间的数据。
然后修改/var/lib/one/.one/one_auth文件内容：oneadmin:123456
好了，这下就能用密码123456登陆了
