解决方案：yum install ruby ruby-devel rubygemsgem install rackgem 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rubyyum remove rubyhttps://www.ruby-lang.org/en/downloads处下载rubytar zxvf ruby-2.2.2-tar.gzcd ruby-2.2.2./configure –with-openssl-dir=/usr/lib/openssl

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
