but  another issue is appear when resolved previous issue

issue 2:   check /var/log/nova/compute-nove.log

 ERROR oslo_messaging._drivers.impl_rabbit [req-74c2a9e1-37fe--98af-6ea48339cb8b - - - - -] AMQP server on controller0: is unreachable: [Errno ] EHOSTUNREACH. Trying again in  seconds.

lead  systemctl start openstack-nova-compute.service  pause all the time

solution:

telnet 22 form compute node to controller node    show successful

[root@compute1 ~]# telnet controller0
Trying 192.168.70.71...
Connected to controller0.
Escape character is '^]'.
SSH-2.0-OpenSSH_6.6.1

telnet 5672 form compute node to controller node    show failed

[root@compute1 ~]# telnet controller0
Trying 192.168.70.71...
telnet: connect to address 192.168.70.71: No route to host

so ，the problem can doubt is firewall.

checke the firewall was  changed in redhat7 or CentOS7 :reference : http://www.zhongweicheng.com/?p=1419

stop and disabled firewall  both compute node and controller node

check firewall status
[root@controller0 ~]# systemctl list-unit-files |grep enabled |grep firewal
firewalld.service                           enabled 

stop firewall
[root@compute1 ~]# systemctl stop firewalld.service

disabled on system boot
[root@compute1 ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

check status of firewall
[root@compute1 ~]# systemctl status firewalld.service 
鈼?firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

audit the issue soluation:

[root@compute1 ~]# telnet controller0

Connected to controller0.
Escape character is '^]'.
Connection closed by foreign host.
