OpenStack Ocata : Configure Nova#3

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.

# install from Ocata, EPEL [root@dlp ~(keystone)]# yum --enablerepo=centos-openstack-ocata,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; [root@dlp ~(keystone)]# 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]	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 | +----+------------------+---------------+----------+---------+-------+----------------------------+ | 5 | nova-cert | dlp.srv.world | internal | enabled | up | 2017-02-28T04:48:27.000000 | | 6 | nova-consoleauth | dlp.srv.world | internal | enabled | up | 2017-02-28T04:48:27.000000 | | 7 | nova-conductor | dlp.srv.world | internal | enabled | up | 2017-02-28T04:48:27.000000 | | 8 | nova-scheduler | dlp.srv.world | internal | enabled | up | 2017-02-28T04:48:17.000000 | | 9 | nova-compute | dlp.srv.world | nova | enabled | up | 2017-02-28T04:48:23.000000 | +----+------------------+---------------+----------+---------+-------+----------------------------+
