我很难配置基于All-In-One单机安装程序的Openstack环境，用于LAN中的桥接网络。
我的目标是通过LAN连接到Openstack中创建的实例。
服务器是Ubuntu 16.04 LTS，安装和OpenSSH最少。服务器的网络配置是：
auto enp3s0
iface enp3s0 inet static
address 10.4.4.1
netmask 255.255.255.0
gateway 10.4.4.254
broadcast 10.4.4.255
network 10.4.4.0
dns-nameservers 10.4.1.12 10.4.1.10
基本上我的网络详情如下：
LAN 10.4.4.0
MASK 255.255.255.0
Gateway/DHCP Server 10.4.4.254
我用于部署devstack的local.conf文件如下：
# Sample ``local.conf`` for user-configurable variables in ``stack.sh``
# NOTE: Copy this file to the root DevStack directory for it to work properly.
# ``local.conf`` is a user-maintained settings file that is sourced from ``stackrc``.
# This gives it the ability to override any variables set in ``stackrc``.
# Also, most of the settings in ``stack.sh`` are written to only be set if no
# value has already been set; this lets ``local.conf`` effectively override the
# default values.
# This is a collection of some of the settings we have found to be useful
# in our DevStack development environments. Additional settings are described
# in https://docs.openstack.org/devstack/latest/configuration.html#local-conf
# These should be considered as samples and are unsupported DevStack code.
# The ``localrc`` section replaces the old ``localrc`` configuration file.
# Note that if ``localrc`` is present it will be used in favor of this section.
[[local|localrc]]
# Minimal Contents
# ----------------
# While ``stack.sh`` is happy to run without ``localrc``, devlife is better when
# there are a few minimal variables set:
# If the ``*_PASSWORD`` variables are not set here you will be prompted to enter
# values for them by ``stack.sh``and they will be added to ``local.conf``.
FLOATING_RANGE=10.4.4.192/27
FIXED_RANGE=192.168.0.0/24
FIXED_NETWORK_SIZE=256
FLAT_INTERFACE=enp3s0
ADMIN_PASSWORD=nomoresecret
DATABASE_PASSWORD=stackdb
RABBIT_PASSWORD=stackqueue
SERVICE_PASSWORD=$ADMIN_PASSWORD
# ``HOST_IP`` and ``HOST_IPV6`` should be set manually for best results if
# the NIC configuration of the host is unusual, i.e. ``eth1`` has the default
# route but ``eth0`` is the public interface. They are auto-detected in
# ``stack.sh`` but often is indeterminate on later runs due to the IP moving
# from an Ethernet interface to a bridge on the host. Setting it here also
# makes it available for ``openrc`` to include when setting ``OS_AUTH_URL``.
# Neither is set by default.
HOST_IP=10.4.4.1
#HOST_IPV6=2001:db8::7
# Logging
# -------
# By default ``stack.sh`` output only goes to the terminal where it runs. It can
# be configured to additionally log to a file by setting ``LOGFILE`` to the full
# path of the destination log file. A timestamp will be appended to the given name.
LOGFILE=$DEST/logs/stack.sh.log
# Old log files are automatically removed after 7 days to keep things neat. Change
# the number of days by setting ``LOGDAYS``.
LOGDAYS=2
# Nova logs will be colorized if ``SYSLOG`` is not set; turn this off by setting
# ``LOG_COLOR`` false.
#LOG_COLOR=False
# Using milestone-proposed branches
# ---------------------------------
# Uncomment these to grab the milestone-proposed branches from the
# repos:
#CINDER_BRANCH=milestone-proposed
#GLANCE_BRANCH=milestone-proposed
#HORIZON_BRANCH=milestone-proposed
#KEYSTONE_BRANCH=milestone-proposed
#KEYSTONECLIENT_BRANCH=milestone-proposed
#NOVA_BRANCH=milestone-proposed
#NOVACLIENT_BRANCH=milestone-proposed
#NEUTRON_BRANCH=milestone-proposed
#SWIFT_BRANCH=milestone-proposed
# Using git versions of clients
# -----------------------------
# By default clients are installed from pip. See LIBS_FROM_GIT in
# stackrc for details on getting clients from specific branches or
# revisions. e.g.
# LIBS_FROM_GIT="python-ironicclient"
# IRONICCLIENT_BRANCH=refs/changes/44/2.../1
# Swift
# -----
# Swift is now used as the back-end for the S3-like object store. Setting the
# hash value is required and you will be prompted for it if Swift is enabled
# so just set it to something already:
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5
# For development purposes the default of 3 replicas is usually not required.
# Set this to 1 to save some resources:
SWIFT_REPLICAS=1
# The data for Swift is stored by default in (``$DEST/data/swift``),
# or (``$DATA_DIR/swift``) if ``DATA_DIR`` has been set, and can be
# moved by setting ``SWIFT_DATA_DIR``. The directory will be created
# if it does not exist.
SWIFT_DATA_DIR=$DEST/data
在部署结束时，我能够从实例ping到我的局域网并在google.com上执行nslookup，但是我无法向后执行，ping / ssh / telnet Openstack中的实例。 安全组允许所有流量，所有ICMP入口/出口，SSH来自任何地方。
我尝试从Openstack实例在本地计算机上远程登录，它显示的是Openstack主机的IP，而不是主机。所以我在网络拓扑中遗漏了一些东西。
netstat -ant | grep 1716
tcp6 0 0 :::1716 :::* LISTEN
tcp6 0 0 10.4.3.34:1716 10.4.4.1:42992 ESTABLISHED
我是否缺少任何类型的网络部署？ 任何建议将不胜感激！
答案 0 :(得分：0)
如果您尝试从“外部”访问实例，则需要创建浮动IP池并为其中一个实例分配浮动IP。
