#安装epel源
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

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
解决方式：
yum install ruby ruby-devel rubygems
gem install rack
gem install sqlite3-ruby
这里依旧是各种失败，后来发现是yum自己主动安装的ruby的版本号过低。又一次安装高版本号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，要依照例如以下设置：
GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin'@'localhost' IDENTIFIED BY 'oneadmin'
SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;
exit;

su oneadmin

sunstone-server start

这是由于在web页面上改动了登录password，可是此更新没有同步到/var/lib/one/.one/one_auth，须要将新password写入到该配置文件里就可以。若该文件权限不正确则也会报错。

忘记oneadmin的默认password

opennebula默认的password是在/var/lib/one/.one/one_auth中。

opennebula使用sha1来加密用户password。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，并且body字段中 间的数据即为相应用户的password加密字符串。

我们用得到的加密字符串来替换user_pool表中username为oneadmin列的body字段中 间的数据。

然后改动/var/lib/one/.one/one_auth文件内容：oneadmin:123456

好了。这下就能用password123456登陆了
