Initial environment configuration
- Copy the contents of the /opt/openstack-ansible/etc/openstack_deploy directory to the/etc/openstack_deploy directory.
- Change to the /etc/openstack_deploy directory.
- Copy the openstack_user_config.yml.example file to/etc/openstack_deploy/openstack_user_config.yml.
shared-infra_hosts有哪些物理机器上可以运行容器来运行openstack服务如databases, memcached, and RabbitMQ，
For details about how the inventory is generated from the environment configuration, seeOpenStack-Ansible Inventory.
Affinity
OpenStack-Ansible 会动态的把容器分布到部署机器上，Using shared-infra_hosts as an example
shared-infra_hosts:
infra1:
ip: 172.29.236.101
infra2:
ip: 172.29.236.102
infra3:
ip: 172.29.236.103
那么，每台机器都会部署a single database container, a single memcached container, and a single RabbitMQ。
如果不需要部署RabbitMQ：
shared-infra_hosts:
infra1:
affinity:
rabbit_mq_container: 0
ip: 172.29.236.101
infra2:
affinity:
rabbit_mq_container: 0
ip: 172.29.236.102
infra3:
affinity:
rabbit_mq_container: 0
ip: 172.29.236.103
Configuring target host networking
在cidr_networks section配置每个网络的IP address ranges
cidr_networks: # Management (same range as br-mgmt on the target hosts) container: CONTAINER_MGMT_CIDR # Tunnel endpoints for VXLAN tenant networks # (same range as br-vxlan on the target hosts) tunnel: TUNNEL_CIDR #Storage (same range as br-storage on the target hosts) storage: STORAGE_CIDR
比如：203.0.113.0/24
Configure the existing IP addresses in the used_ips section:
used_ips: - EXISTING_IP_ADDRESSES
使用过的IP包括前面manually configured on target hosts, internal load balancers, service network bridge, deployment hosts
Configure load balancing in the global_overrides section:
global_overrides: # Internal load balancer VIP address internal_lb_vip_address: INTERNAL_LB_VIP_ADDRESS # External (DMZ) load balancer VIP address external_lb_vip_address: EXTERNAL_LB_VIP_ADDRESS # Container network bridge device management_bridge: "MGMT_BRIDGE" # Tunnel network bridge device tunnel_bridge: "TUNNEL_BRIDGE"
Configure the management network in the provider_networks subsection:
provider_networks:
- network:
group_binds:
- all_containers
- hosts
type: "raw"
container_bridge: "br-mgmt"
container_interface: "eth1"
container_type: "veth"
ip_from_q: "container"
is_container_address: true
is_ssh_address: true
比如要配置可选的storage network：
provider_networks:
- network:
group_binds:
- glance_api
- cinder_api
- cinder_volume
- nova_compute
type: "raw"
container_bridge: "br-storage"
container_type: "veth"
container_interface: "eth2"
ip_from_q: "storage"
Configure OpenStack Networking VXLAN tunnel/overlay networks in the provider_networkssubsection:
provider_networks:
- network:
group_binds:
- neutron_linuxbridge_agent
container_bridge: "br-vxlan"
container_type: "veth"
container_interface: "eth10"
ip_from_q: "tunnel"
type: "vxlan"
range: "TUNNEL_ID_RANGE"
net_name: "vxlan"
Configure OpenStack Networking flat (untagged) and VLAN (tagged) networks in theprovider_networks subsection:
provider_networks:
- network:
group_binds:
- neutron_linuxbridge_agent
container_bridge: "br-vlan"
container_type: "veth"
container_interface: "eth12"
host_bind_override: "PHYSICAL_NETWORK_INTERFACE"
type: "flat"
net_name: "flat"
- network:
group_binds:
- neutron_linuxbridge_agent
container_bridge: "br-vlan"
container_type: "veth"
container_interface: "eth11"
type: "vlan"
range: VLAN_ID_RANGE
net_name: "vlan"
Adding static routes to network interfaces
可选，每个route都需要a destination network in CIDR notation and a gateway，比如：
provider_networks:
- network:
group_binds:
- glance_api
- cinder_api
- cinder_volume
- nova_compute
type: "raw"
container_bridge: "br-storage"
container_interface: "eth2"
container_type: "veth"
ip_from_q: "storage"
static_routes:
- cidr: 10.176.0.0/12
gateway: 172.29.248.1
效果是其在/etc/network/interfaces.d/eth2.cfg增加了
post-up ip route add 10.176.0.0/12 via 172.29.248.1 || true
Setting an MTU on a network interface
对于存储网络很有用：
provider_networks:
- network:
group_binds:
- glance_api
- cinder_api
- cinder_volume
- nova_compute
type: "raw"
container_bridge: "br-storage"
container_interface: "eth2"
container_type: "veth"
container_mtu: "9000"
ip_from_q: "storage"
static_routes:
- cidr: 10.176.0.0/12
gateway: 172.29.248.1
The example above enables jumbo frames by setting the MTU on the storage network to 9000
Configuring target hosts
Configure a list containing at least three infrastructure target hosts in the shared-infra_hostssection:
shared-infra_hosts:
infra01:
ip: INFRA01_IP_ADDRESS
infra02:
ip: INFRA02_IP_ADDRESS
infra03:
ip: INFRA03_IP_ADDRESS
infra04: ...
Configure a list containing at least two infrastructure target hosts in the os-infra_hostssection (you can reuse previous hosts as long as their name and ip is consistent):
os-infra_hosts:
infra01:
ip: INFRA01_IP_ADDRESS
infra02:
ip: INFRA02_IP_ADDRESS
infra03:
ip: INFRA03_IP_ADDRESS
infra04: ...
Configure a list of at least one keystone target host in the identity_hosts section:
identity_hosts:
infra1:
ip: IDENTITY01_IP_ADDRESS
infra2: ...
Configure a list containing at least one compute target host in the compute_hosts section:
compute_hosts:
compute001:
ip: COMPUTE001_IP_ADDRESS
compute002: ...
。。。。。。。
Configuring service credentials
Configuring the Compute (nova) service (optional)
Configuring the Image (glance) service
Configuring the Block (cinder) storage service (optional)
Configuring HAProxy (optional)
最好使用硬件HA在配置服务HA
To deploy HAProxy within your OpenStack-Ansible environment, define target hosts to run HAProxy:
haproxy_hosts:
infra1:
ip: 172.29.236.101
infra2:
ip: 172.29.236.102
infra3:
ip: 172.29.236.103
Configuring the Telemetry (ceilometer) service (optional)
Configuring the Identity service (keystone) (optional)
Overriding OpenStack configuration defaults
Overriding .conf files
比如要在nova.conf设置
[DEFAULT] remove_unused_original_minimum_age_seconds = 43200 [libvirt] cpu_mode = host-model disk_cachemodes = file=directsync,block=none [database] idle_timeout = 300 max_pool_size = 10
可以在/etc/openstack_deploy/user_variables.yml配置：
nova_nova_conf_overrides:
DEFAULT:
remove_unused_original_minimum_age_seconds: 43200
libvirt:
cpu_mode: host-model
disk_cachemodes: file=directsync,block=none
database:
idle_timeout: 300
max_pool_size: 10
如果是对特定的server配置：
compute_hosts:
900089-compute001:
ip: 192.0.2.10
host_vars:
nova_nova_conf_overrides:
DEFAULT:
remove_unused_original_minimum_age_seconds: 43200
libvirt:
cpu_mode: host-model
disk_cachemodes: file=directsync,block=none
database:
idle_timeout: 300
max_pool_size: 10
Overriding .json files
用来adjust the default policies
/etc/openstack_deploy/user_variables.yml:
keystone_policy_overrides: identity:foo: "rule:admin_required" identity:bar: "rule:admin_required"
