OpenStack/devstack with Neutron on Ubuntu 14 (1)

时间：2023-03-08 22:11:45

安装前，推荐安装一个全新的Ubuntu Server14.04，如果使用之前的ubuntu， 中间可能遇到各种的python包依赖，以及软件版本不对应的问题

  • 环境准备，新建stack用户，给予sudo权限，更新系统软件包
 # add user 'stack'

 sudo su

 useradd -m -p welcome -s /bin/bash stack

 # add sudo previledge

 sudo su

 # Modify /etc/sudoers

 cat >>/etc/sudoers <<'EOF'

 stack   ALL=(ALL) NOPASSWD: ALL

 Defaults:stack !requiretty

 EOF

 exit

 # Update software respository cache

 sudo apt-get install -y python-software-properties

 sudo add-apt-repository cloud-archive:juno

 sudo apt-get update -y && sudo apt-get dist-upgrade -y

 sudo shutdown -r now
  • 下载devstack， 配置local.conf
# install git download devstack
sudo apt-get install -qqy git

git clone http://www.github.com/openstack-dev/devstack.git

cd devstack

touch local.conf

vim local.conf

#place following in local.conf, change the HOST_IP and SERVICE_HOST to the IP of eth0

[[local|localrc]]

HOST_IP=192.168.20.140

SERVICE_HOST=192.168.20.140

ADMIN_PASSWORD=welcome

DATABASE_PASSWORD=$ADMIN_PASSWORD

RABBIT_PASSWORD=$ADMIN_PASSWORD

SERVICE_PASSWORD=$ADMIN_PASSWORD

SERVICE_TOKEN=$ADMIN_PASSWORD

DEST=/opt/stack

LOGFILE=$DEST/logs/stack.sh.log

SCREEN_LOGDIR=$DEST/logs/screen

OFFLINE=False

RECLONE=True

LOG_COLOR=False

disable_service horizon

enable_service q-svc

enable_service q-agt

enable_service q-dhcp

enable_service q-l3

enable_service q-meta

enable_service neutron

disable_service n-net

disable_service tempest

disable_service h-eng,h-api,h-api-cfn,h-api-cw

PHYSICAL_NETWORK=physnet1

FIXED_RANGE=192.168.106.0/

FIXED_NETWORK_SIZE=

NETWORK_GATEWAY=192.168.106.1

[[post-config|/$Q_PLUGIN_CONF_FILE]]

[ml2]

tenant_network_types = vlan

[ml2_type_vlan]

network_vlan_ranges = physnet1:100:110

[ovs]

bridge_mappings = physnet1:br-eth1

enable_tunneling = False
  • 启动安装devstack
#由于国内对git可能进行了block，所以如果不能访问git：这种地址，可以换成http：的试试
sed -i 's|GIT_BASE:-git://git.openstack.org|GIT_BASE:-http://git.openstack.org|' stackrc
cd ~/devstack

./stack.sh
  • 配置虚拟网桥
#add br-eth1 add connect with eth1

sudo ovs-vsctl add-br br-eth1

sudo ovs-vsctl --may-exist add-port br-eth1 eth1

# set eth1 to promisc mode, so that it can pass any package in L2

sudo ip link set dev eth1 promisc on

sudo ip addr flush eth1

sudo ip link set dev eth1 up

这样一个带neutron的devstack环境就架设好了，这个过程我想不会顺利，devstack/openstack时常在更新，所以每天都会有不同的问题，大家如果安装遇到问题，可以留言讨论，当然如果文档有问题，也烦请指出。
