dhcp_agent.ini

dhcp agent 相关的配置信息。包括与 neutron 的同步状态的频率、超时、驱动信息等。

需要注意的是,这些 ini 文件内容多为注释掉的默认值的情况,是自动从代码中提取的。

hcp.Dnsmasq

# Allow overlapping IP (Must have kernel build with CONFIG_NET_NS=y and
# iproute2 package that supports namespaces).
# use_namespaces = True

# The DHCP server can assist with providing metadata support on isolated
# networks. Setting this value to True will cause the DHCP server to append
# specific host routes to the DHCP request. The metadata service will only
# be activated when the subnet does not contain any router port. The guest
# instance must be configured to request host routes via DHCP (Option 121).
# enable_isolated_metadata = False

# Allows for serving metadata requests coming from a dedicated metadata
# access network whose cidr is 169.254.169.254/16 (or larger prefix), and
# is connected to a Neutron router from which the VMs send metadata
# request. In this case DHCP Option 121 will not be injected in VMs, as
# they will be able to reach 169.254.169.254 through a router.
# This option requires enable_isolated_metadata = True
# enable_metadata_network = False

# Number of threads to use during sync process. Should not exceed connection
# pool size configured on server.
# num_sync_threads = 4

# Location to store DHCP server config files
# dhcp_confs = $state_path/dhcp

# Domain to use for building the hostnames
# dhcp_domain = openstacklocal

# Override the default dnsmasq settings with this file
# dnsmasq_config_file =

# Comma-separated list of DNS servers which will be used by dnsmasq
# as forwarders.
# dnsmasq_dns_servers =

# Limit number of leases to prevent a denial-of-service.
# dnsmasq_lease_max = 16777216

# Location to DHCP lease relay UNIX domain socket
# dhcp_lease_relay_socket = $state_path/dhcp/lease_relay

# Use broadcast in DHCP replies
# dhcp_broadcast_reply = False

# Location of Metadata Proxy UNIX domain socket
# metadata_proxy_socket = $state_path/metadata_proxy

# dhcp_delete_namespaces, which is false by default, can be set to True if
# namespaces can be deleted cleanly on the host running the dhcp agent.
# Do not enable this until you understand the problem with the Linux iproute
# utility mentioned in https://bugs.launchpad.net/neutron/+bug/1052535 and
# you are sure that your version of iproute does not suffer from the problem.
# If True, namespaces will be deleted when a dhcp server is disabled.
# dhcp_delete_namespaces = False

# Timeout for ovs-vsctl commands.
# If the timeout expires, ovs commands will fail with ALARMCLOCK error.
# ovs_vsctl_timeout = 10
