　　Creating group 'rvm'
　　Installing RVM to /usr/local/rvm/
　　Installation of RVM in /usr/local/rvm/ is almost complete:
　　* First you need to add all users that will be using rvm to 'rvm' group,
　　and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
　　* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
　　in all your open shell windows, in rare cases you need to reopen all shell windows.
　　[root@localhost ~]# source /etc/profile.d/rvm.sh
　　[root@localhost ~]# rvm -v
