OpenStack Pike : Configure Nova#32017/09/03 |
|
Install OpenStack Compute Service (Nova).
This example is based on the emvironment like follows.
If you'd like to install Nova Compute on another Computer, refer to here.
eth0|10.0.0.30
+-----------+-----------+
| [ Control Node ] |
| |
| MariaDB RabbitMQ |
| Memcached httpd |
| Keystone Glance |
| Nova API,Compute |
+-----------------------+
|
| [1] |
Install KVM HyperVisor on Compute Host, refer to here.
It's unnecessarry to set Bridge networking on the section [2] of the link. |
| [2] | Install Nova Compute. |
|
[root@dlp ~(keystone)]# yum --enablerepo=centos-openstack-pike,epel -y install openstack-nova-compute
|
| [3] | In addition to basic settings of Nova, add following settings. |
|
[root@dlp ~(keystone)]#
vi /etc/nova/nova.conf # add follows
# enable VNC
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = 10.0.0.30
novncproxy_base_url = http://10.0.0.30:6080/vnc_auto.html
|
| [4] | If SELinux is enabled, change policy like follows. |
|
[root@dlp ~(keystone)]#
vi nova-compute_pol.te # create new
module nova-compute_pol 1.0;
require {
type nova_var_lib_t;
type virtlogd_t;
class capability dac_override;
class file { append getattr open };
class dir search;
}
#============= virtlogd_t ==============
allow virtlogd_t nova_var_lib_t:dir search;
allow virtlogd_t nova_var_lib_t:file { append getattr open };
allow virtlogd_t self:capability dac_override;

| [5] | If Firewalld is running, allow service ports. |
|
[root@dlp ~(keystone)]# firewall-cmd --add-port=5900-5999/tcp --permanent success [root@dlp ~(keystone)]# firewall-cmd --reload success |
| [6] | Start Nova Compute. |
|
[root@dlp ~(keystone)]#
systemctl start openstack-nova-compute [root@dlp ~(keystone)]# systemctl enable openstack-nova-compute
# discover Compute Node [root@dlp ~(keystone)]# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
