多节点 devstack 部署

时间：2023-03-08 18:21:49

1， 网络配置

每个节点 /etc/network/interfaces

auto eth0

iface eth0 inet static

    address 192.168.42.11

    netmask 255.255.255.0

    gateway 192.168.42.1

2, 添加stack用户

# groupadd stack

# useradd -g stack -s /bin/bash -d /opt/stack -m stack

# echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

3， setup ssh authorized_keys, 保证各节点之间ssh通信畅通

$ ssh-keygen

$ echo "<public ssh_key of another nodes>" > ~/.ssh/authorized_keys

4， 下载devstack

$ git clone https://git.openstack.org/openstack-dev/devstack

$ cd devstack

5, 安装controller：

编辑local.conf如下：

[[local|localrc]]

HOST_IP=192.168.42.11

FLAT_INTERFACE=eth0

FIXED_RANGE=10.4.128.0/

FIXED_NETWORK_SIZE=

FLOATING_RANGE=192.168.42.128/

MULTI_HOST=

LOGFILE=/opt/stack/logs/stack.sh.log

ADMIN_PASSWORD=labstack

DATABASE_PASSWORD=supersecret

RABBIT_PASSWORD=supersecret

SERVICE_PASSWORD=supersecret

执行stack.sh

$ ./stack.sh

添加文件local.sh, 每次执行完一个节点的stack.sh就执行local.sh一次：

for i in `seq  `; do /usr/local/bin/nova-manage fixed reserve 10.4..$i; done

6， 按装compute节点：

编辑local.conf文件：

[[local|localrc]]

HOST_IP=192.168.42.12 # change this per compute node

FLAT_INTERFACE=eth0

FIXED_RANGE=10.4.128.0/

FIXED_NETWORK_SIZE=

FLOATING_RANGE=192.168.42.128/

MULTI_HOST=

LOGFILE=/opt/stack/logs/stack.sh.log

ADMIN_PASSWORD=labstack

DATABASE_PASSWORD=supersecret

RABBIT_PASSWORD=supersecret

SERVICE_PASSWORD=supersecret

DATABASE_TYPE=mysql

SERVICE_HOST=192.168.42.11

MYSQL_HOST=$SERVICE_HOST

RABBIT_HOST=$SERVICE_HOST

GLANCE_HOSTPORT=$SERVICE_HOST:

ENABLED_SERVICES=n-cpu,n-net,n-api-meta,c-vol

NOVA_VNC_ENABLED=True

NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"

VNCSERVER_LISTEN=$HOST_IP

VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN

执行stack.sh

$ ./stack.sh

7， 安装完毕

8, live-migration notification:

every compute node’s root user’s public RSA key must exist in every other compute node’s stack user’s authorized_keys file and every compute node’s public ECDSA key needs to be in every other compute node’s root user’s known_hosts file.
