Hi,

Just trying to install OpenNebula 5.0 on Centos 7 and stuck in FE installation. I’m following the docs here:  
[http://docs.opennebula.org/5.0/deployment/opennebula\_installation/frontend\_installation.html#frontend-installation](http://docs.opennebula.org/5.0/deployment/opennebula_installation/frontend_installation.html#frontend-installation)  
I’ve installed mysql and applied the instructions here:  
[http://docs.opennebula.org/5.0/deployment/opennebula\_installation/mysql\_setup.html#mysql-setup](http://docs.opennebula.org/5.0/deployment/opennebula_installation/mysql_setup.html#mysql-setup)

On Step 6. Starting OpenNebula:  
logged in as oneadmin and then changed the password by echo “oneadmin:xxxxx” \> ~/.one/one\_auth  
then, run below commands as root:  
service opennebula start  
service opennebula-sunstone start  
No error yet, but when i try to verify installation, i get following:  
[oneadmin@localhost ~]$ oneuser show  
Connection refused - connect(2)

## here’re the logs: [root@localhost one]# cat sched.log-20160530-1464596071 Mon May 30 11:14:24 2016 [Z0][SCHED][I]: Init Scheduler Log system Mon May 30 11:14:24 2016 [Z0][SCHED][I]: Starting Scheduler Daemon

my mistake… figured out that it was because of a missing # in oned.conf…  
you can close this thread,

thanks,
