Openstack_O版(otaka)部署

控制节点配置

1. 建库建用户

CREATE DATABASE nova_api;
 
CREATE DATABASE nova;
 
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '';
 
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '';
 
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '';
 
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '';
 
flush privileges;

2. keystone相关操作

3. 安装软件包

 yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler -y
 yum install openstack-nova-placement-api

4. 修改配置

vim /etc/nova/nova.conf

[DEFAULT]
 
enabled_apis = osapi_compute,metadata
 
rpc_backend = rabbit
 
auth_strategy = keystone
 
transport_url = rabbit://openstack:123456@controller
 
#下面的为管理ip
 
my_ip = 192.168.198.128
 
use_neutron = True
 
firewall_driver = nova.virt.firewall.NoopFirewallDriver
 
[api_database]
 
connection = mysql+pymysql://nova:123456@controller/nova_api
 
[database]
 
connection = mysql+pymysql://nova:123456@controller/nova
 
[oslo_messaging_rabbit]
 
rabbit_host = controller
 
rabbit_userid = openstack
 
rabbit_password = 123456
 
[keystone_authtoken]
 
auth_url = http://controller:5000
 
memcached_servers = controller:11211
 
auth_type = password
 
project_domain_name = default
 
user_domain_name = default
 
project_name = service
 
username = nova
 
password = 123456
 
[vnc]
 
enabled = True
 
# 下面的为管理ip
 
vncserver_listen = 192.168.198.128
 
# 下面的为管理ip
 
vncserver_proxyclient_address = 192.168.198.128
 
[glance]
 
api_servers = http://controller:9292
 
[placement]
 
auth_url = http://controller:35357/v3
 
auth_type=password
 
os_region_name = RegionOne
 
project_domain_name = default
 
user_domain_name = default
 
region_name = RegionOne
 
project_name = service
 
username = neutron
 
password = 123456
 
[oslo_concurrency]
 
lock_path = /var/lib/nova/tmp

vim /etc/httpd/conf.d/00-nova-placement-api.conf

# append this code 
 
<Directory /usr/bin>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>
<IfVersion < 2.4>
    Order allow,deny
    Allow from all
</IfVersion>
</Directory>

5. 同步数据库

此处会报一些关于future的问题，自行忽略

 su -s /bin/sh -c "nova-manage api_db sync" nova
 su -s /bin/sh -c "nova-manage db sync" nova

6. 启动服务

 systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service
 systemctl enable openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
 systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service
 systemctl start openstack-nova-conductor.service openstack-nova-novncproxy.service

7. 验证

netstat -ntlp | grep 6080 
 
    tcp        0      0 0.0.0.0:6080            0.0.0.0:*               LISTEN      85554/python2 
 
netstat -ntlp | grep 8774
 
    tcp        0      0 0.0.0.0:8774            0.0.0.0:*               LISTEN      85481/python2 
 
netstat -ntlp | grep 8775
 
    tcp        0      0 0.0.0.0:8775            0.0.0.0:*               LISTEN      85481/python2

计算节点配置

1. 安装软件包

yum install openstack-nova-compute libvirt-daemon-lxc -y

2. 修改配置

vim /etc/nova/nova.conf

[DEFAULT]
 
rpc_backend = rabbit
 
auth_strategy = keystone
 
#计算节点管理网络ip
 
my_ip = 192.168.198.129
 
use_neutron = True
 
firewall_driver = nova.virt.firewall.NoopFirewallDriver
 
enabled_apis = osapi_compute,metadata
 
transport_url = rabbit://openstack:123456@controller
 
[oslo_messaging_rabbit]
 
rabbit_host = controller
 
rabbit_userid = openstack
 
rabbit_password = 123456
 
[vnc]
 
enabled = True
 
vncserver_listen = 0.0.0.0
 
#计算节点管理网络ip
 
vncserver_proxyclient_address = 192.168.198.129
 
#控制节点管理网络ip
 
novncproxy_base_url = http://192.168.198.128:6080/vnc_auto.html
 
[glance]
 
api_servers = http://controller:9292
 
[oslo_concurrency]
 
lock_path = /var/lib/nova/tmp
 
[placement]
 
auth_url = http://controller:5000
 
memcached_servers = controller:11211
 
auth_type = password
 
project_domain_name = default
 
user_domain_name = default
 
project_name = service
 
username = nova
 
password = 123456
 
os_region_name = RegionOne
 
[scheduler]
 
discover_hosts_in_cells_interval = 300
 
[database]
 
connection = mysql+pymysql://root:secret@192.168.111.69/nova_cell0?charset=utf8
 
[api_database]
 
connection = mysql+pymysql://root:secret@192.168.111.69/nova_api?charset=utf8

3. 如果在不支持虚拟化的机器上部署nova，请确认

egrep -c '(vmx|svm)' /proc/cpuinfo结果为0
 
# 则编辑/etc/nova/nova.conf
 
vim /etc/nova/nova.conf
 
    [libvirt]
 
    virt_type = qemu
 
. admin-openrc
 
openstack hypervisor list
 
# Discover compute hosts
 
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

4. 启动服务

 systemctl enable libvirtd.service openstack-nova-compute.service
 systemctl start libvirtd.service openstack-nova-compute.service

验证

控制节点

source admin-openrc
 
openstack compute service list
