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; checkmodule -m -M -o nova-compute_pol.mod nova-compute_pol.te checkmodule: loading policy configuration from nova_pol.te checkmodule: policy configuration loaded checkmodule: writing binary representation (version 17) to nova_pol.mod [root@dlp ~(keystone)]# semodule_package --outfile nova-compute_pol.pp --module nova-compute_pol.mod [root@dlp ~(keystone)]# semodule -i nova-compute_pol.pp |
[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"
# show status [root@dlp ~(keystone)]# openstack compute service list +----+------------------+---------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+------------------+---------------+----------+---------+-------+----------------------------+ | 4 | nova-consoleauth | dlp.srv.world | internal | enabled | up | 2017-09-04T06:01:36.000000 | | 5 | nova-conductor | dlp.srv.world | internal | enabled | up | 2017-09-04T06:01:36.000000 | | 6 | nova-scheduler | dlp.srv.world | internal | enabled | up | 2017-09-04T06:01:36.000000 | | 7 | nova-compute | dlp.srv.world | nova | enabled | up | None | +----+------------------+---------------+----------+---------+-------+----------------------------+ |
