Configure a compute node
1 , Installthe Compute packages:
# yum install openstack-nova-compute
2, Edit the /etc/nova/nova.conf configuration file:
# openstack-config --set /etc/nova/nova.conf database connection mysql://nova:novapw@controller/nova
# openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_host controller
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_protocol http
# openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_port 35357
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_user nova
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_tenant_name service
# openstack-config --set /etc/nova/nova.conf keystone_authtoken admin_password novapw
3, Configure the Compute service to use the Qpid message broker by setting these configuration keys:
# openstack-config --set /etc/nova/nova.conf \
DEFAULT rpc_backend qpid
# openstack-config --set /etc/nova/nova.conf DEFAULT qpid_hostname controller
4, Configure Compute to provide remote console access to instances.
# openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 192.168.1.212
# openstack-config --set /etc/nova/nova.conf DEFAULT vnc_enabled True
# openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_listen 0.0.0.0
# openstack-config --set /etc/nova/nova.conf DEFAULT vncserver_proxyclient_address 192.168.1.212
# openstack-config --set /etc/nova/nova.conf \
DEFAULT novncproxy_base_url http://controller:6080/vnc_auto.html
5, Specify the host that runs the Image Service.
# openstack-config --set /etc/nova/nova.conf DEFAULT glance_host controller
6, You must determine whether your system's processor and/or hypervisor support hardware acceleration for virtual machines.
# egrep -c '(vmx|svm)' /proc/cpuinfo
0
If this command returns a value of zero, your system does not supporthardware acceleration and you must configure libvirt to use QEMU instead of KVM.
a. Run the following command:
# openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu
7
# service libvirtd start
# service messagebus start
# chkconfig libvirtd on
# chkconfig messagebus on
# service openstack-nova-compute start
# chkconfig openstack-nova-compute on
