OpenStack Grizzly - Add Compute Nodes2013/08/19 |
|
Add Compute Nodes to run more instanes.
The example below shows to configure a Compute Node on another Computer from Control Node's one.
|
|
| [1] |
Install KVM Hypervisor first which needs on Compute Node.
It's unnecessarry to set Bridge networking on the section [2] of the link.
|
| [2] | Install Nova-Compute, Nova-Network |
|
# install from EPEL OpenStack, EPEL [root@node01 ~]# yum --enablerepo=epel-openstack-grizzly,epel -y install openstack-nova-compute openstack-nova-network
|
| [3] | Configure Nova |
|
[root@node01 ~]#
vi /etc/nova/nova.conf # line 14: specify IP address and MySQL nova user's password on the Controle Node sql_connection = mysql://nova: password @10.0.0.30 /nova
# line 19: add or change like follows # it's OK for the 7 lines below to set the same settings for Control Node auth_strategy = keystone libvirt_type = kvm volume_api_class = nova.volume.cinder.API enabled_apis = ec2,osapi_compute,metadata public_interface = eth0 flat_interface = lo flat_network_bridge = br100
vnc_enabled = True
# specify this Compute Node's hostname or IP address vncserver_listen = 10.0.0.31 # specify this Compute Node's hostname or IP address vncserver_proxyclient_address = 10.0.0.31 # specify Control Node's hostname or IP address novncproxy_base_url = http://10.0.0.30:6080/vnc_auto.html novncproxy_port = 6080 # specify Glance's hostname or IP address ( it's Control Node's one on this example) glance_api_servers = 10.0.0.30:9292 # specify Qpid's hostname or IP address ( it's Control Node's one on this example) qpid_hostname = 10.0.0.30 qpid_port = 5672 # specify Memcached's hostname or IP address ( it's Control Node's one on this example) memcached_servers = 10.0.0.30:11211

| [4] | Make sure services are working normally. It's OK if the status of services are like follows. |
