Installing Opennebula On Clean Centos 7 Problem

I got SP 64-S server from recent OVH BF deals. Usually I use Proxmox for virtualization on all of my servers, now I want to explore with opennebula on centos 7.

I install centos 7 with default kernel with about 10 G swap and / for the rest. Selinux was already disabled.

To install opennebula, I follow tutorial here:

The first error I got was I can't install one gem (I forget the name) because default centos ruby version is 2.0.0, and the gem installation needs 2.2.0 version.

After that, I try to install ruby version 2.3.0 first from here:
and then I follow the opennebula docs again.

The installation was successful with no error message, but when try this command:

service opennebula-sunstone start

it fail, and this is the error message from /var/log/one/sunstone.error

/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- sinatra (LoadError)
        from /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require'
        from /usr/lib/one/sunstone/sunstone-server.rb:57:in `'

I try gem list, and there is sinatra there
