二、多节点部署 ubuntu20.04 LTS安装OpenStack Wallaby版本。一个controller节点，两个compute节点。
1. 环境准备
【环境准备】部分的所有操作均需要在各节点 执行。
1.1 换源、依赖安装 1.1.1 镜像源 sudo vim /etc/apt/sources.list
1 2 3 4 5 6 7 8 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
更新软件包：sudo apt update && sudo apt upgrade
1.1.2 pip源 sudo mkdir ~/.pip && sudo vim ~/.pip/pip.conf
1 2 3 4 [global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple [install] trusted-host = pypi.tuna.tsinghua.edu.cn
1.1.3 安装部分依赖包 有的依赖包不安装后面可能会出错，因此先手动安装
1 2 sudo apt install bridge-utils git python3-pip sudo pip3 install wheel
1.2 添加stack用户 添加用户stack，并设置为无密码可执行sudo命令。
1 2 3 4 5 6 7 8 9 10 11 sudo useradd -s /bin/bash -d /opt/stack -m stack echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stacksudo su - stack sudo passwd stack
1.3 设置代理 通过export设置的代理仅在当前终端下有效，重新打开终端后也需重新设置。
1 2 3 4 5 export HTTP_PROXY=http://proxy_ip:portexport HTTPS_PROXY=http://proxy_ip:port
1.4 设置免密登录 1.4.1 修改hosts文件 修改hosts文件，并添加各节点的ip地址：vim /etc/hosts
1 2 3 172.19.204.30 h3c-node01 compute2 172.19.204.20 h3c-node02 compute1 172.19.204.10 h3c-node03 controller
1.4.2 配置免密登录 1 2 3 4 5 6 7 8 9 10 11 12 ssh-keygen ssh-copy-id stack@controller ssh-copy-id stack@compute1 ssh-copy-id stack@compute2 ssh stack@controller ssh stack@compute1 ssh stack@compute2
1.5 下载devstack安装库 通过-b指定版本。
git clone https://opendev.org/openstack/devstack.git -b stable/wallaby
2. 安装 先安装好controller，再安装computer节点。默认安装路径在/opt/stack
2.1 controller节点 2.1.1 修改devstack的配置文件 1. 创建local.conf文件 在下载的git仓库devstack目录下创建配置文件local.conf。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 [[local |localrc]] HOST_IP=172.19.204.10 GIT_BASE=http://git.trystack.cn OS_AUTH_URL=http://172.19.204.10:5000/v3 MULTI_HOST=1 LOGFILE=/opt/stack/logs/stack.sh.log DEST=/opt/stack ADMIN_PASSWORD=123 DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD
2.2 computer节点 在下载的git仓库devstack目录下创建配置文件local.conf。
2.2.1 computer1节点 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 [[local |localrc]] HOST_IP=172.19.204.20 GIT_BASE=http://git.trystack.cn OS_AUTH_URL=http://172.19.204.10:5000/v3 MULTI_HOST=1 LOGFILE=/opt/stack/logs/stack.sh.log DEST=/opt/stack ADMIN_PASSWORD=123 DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD DATABASE_TYPE=mysql SERVICE_HOST=172.19.204.10 MYSQL_HOST=$SERVICE_HOST RABBIT_HOST=$SERVICE_HOST GLANCE_HOSTPORT=$SERVICE_HOST :9292 ENABLED_SERVICES=n-cpu,c-vol,placement-client,ovn-controller,ovs-vswitchd,ovsdb-server,q-ovn-metadata-agent NOVA_VNC_ENABLED=True NOVNCPROXY_URL="http://$SERVICE_HOST :6080/vnc_auto.html" VNCSERVER_LISTEN=$HOST_IP VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN
2.2.2 computer2节点 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 [[local |localrc]] HOST_IP=172.19.204.30 GIT_BASE=http://git.trystack.cn OS_AUTH_URL=http://172.19.204.10:5000/v3 MULTI_HOST=1 LOGFILE=/opt/stack/logs/stack.sh.log DEST=/opt/stack ADMIN_PASSWORD=123 DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD DATABASE_TYPE=mysql SERVICE_HOST=172.19.204.10 MYSQL_HOST=$SERVICE_HOST RABBIT_HOST=$SERVICE_HOST GLANCE_HOSTPORT=$SERVICE_HOST :9292 ENABLED_SERVICES=n-cpu,c-vol,q-agt,placement-client,ovn-controller,ovs-vswitchd,ovsdb-server,q-ovn-metadata-agent NOVA_VNC_ENABLED=True NOVNCPROXY_URL="http://$SERVICE_HOST :6080/vnc_auto.html" VNCSERVER_LISTEN=$HOST_IP VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN
2.3 修改配置
各节点均需要执行
2.3.1 nova.conf 避免出现 [错误: Build of instance 6ec6e8b1-9300-4be4-95fe-20434ea041f5 aborted: Volume e3dcad3d-dd22-4947-99d8-b8d0ad4b1025 did not finish being created even after we waited 187 seconds or 61 attempts. And its status is error.]问题。
修改nova.conf，添加以下参数设置。
1 2 3 4 5 6 7 8 [root@cinder ~] block_device_allocate_retries=600 block_device_allocate_retries_interval=5 block_device_creation_timeout=600 [root@cinder ~]
2.3.2 修改卷组位置 修改OpenStack创建虚拟机时分配磁盘的位置。
查看/etc/cinder/cinder.conf，搜索volume_group对应的值，默认为stack-volumes-lvmdriver-1
输入命令vgs查看当前vg，删除不需要的vg， vgremove ****
1 2 3 4 5 6 7 stack@controller:/$ sudo vgs VG stack-volumes-default 1 0 0 wz--n- <30.00g <30.00g stack-volumes-lvmdriver-1 1 1 0 wz--n- <30.00g 1.43g vgubuntu 1 2 0 wz--n- 1.09t 0 stack@controller:/$ sudo vgremove stack-volumes-lvmdriver-1
在对应的磁盘上创建vg
1 2 sudo pvcreate /dev/sdc sudo vgcreate stack-volumes-lvmdriver-1 /dev/sdc
重启服务，sudo systemctl restart devstack@*
2.4 上传镜像
修改镜像格式（qcow2转raw）
qemu-img convert -f qcow2 win7.qcow2 -O raw win7.raw
1 openstack image create "ubuntu20-server" --file ubuntu20-server.qcow2 --disk-format qcow2 --container-format bare --public
2.5 在指定compute节点创建实例
查看可用zone：openstack availability zone list
查看可用host：openstack host list
查看可用node：openstack hypervisor list
查看网络：openstack network list
1 openstack server create --flavor ds1G --image ubuntu20-server --nic net-id=937ba92f-4f53-4da2-a1a6-6d4e1cf433bf --availability-zone nova:compute1:compute1 ubuntu1-1
–flavor：实例类型
–image：镜像
–nic：网络 net-id网络id 第4步查得
–availability-zone nova:compute1:compute1 前三步查得
查看各计算节点的虚拟机
nova list –host controller –all-tenants
nova list –host compute1 –all-tenants
2.6 修改虚拟机网络配置 创建实例后，可以分配浮动IP ，从而可以从外部直接操作虚拟机。
2.6.1 ubuntu20 默认使用netplan管理网络配置，修改/etc/netplan/****.yaml，修改网卡名称，设置DHCP并添加DNS，否则无法通过域名访问外部网络。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 vim /etc/netplan/****.yaml network: ethernets: ens3: dhcp4: true nameservers: addresses: [114.114.114.114,8.8.8.8] version: 2 sudo netplan apply
2.6.2 ubuntu16
在/etc/network/interfaces.d/***.cfg中添加DNS服务器，添加dns-nameserver 114.114.114.114
生效：sudo /etc/init.d/networking restart，sudo /etc/init.d/resolvconf restart
2.7 修改网络安全组规则 默认安全组规则不允许从外部进行SSH操作与ping操作，因此需要开启22端口与ICMP规则，可以直接将ICMP、TCP、UDP的所有端口的出入口规则打开。
三、DevStack相关组件 devstack相关组件均通过systemctl进行控制，其日志信息通过journalctl查看。
c-*是cinder，g-*是glance，n-*是nova，o-*是octavia，q-*是neutron。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 /etc/systemd/system/ | grep devstack | awk ‘{print $9 }’ 输出： devstack@c-api.service devstack@c-sch.service devstack@c-vol.service devstack@dstat.service devstack@etcd.service devstack@g-api.service devstack@keystone.service devstack@n-api-meta.service devstack@n-api.service devstack@n-cond-cell1.service devstack@n-cpu.service devstack@n-novnc-cell1.service devstack@n-sch.service devstack@n-super-cond.service devstack@placement-api.service devstack@q-agt.service devstack@q-dhcp.service devstack@q-l3.service devstack@q-meta.service devstack@q-svc.service
四、可能遇到的问题 1. Host is not mapped to any cell 在控制节点执行nova-manage cell_v2 discover_hosts --verbose
1 2 3 4 5 6 7 8 9 stack@controller:~$ nova-manage cell_v2 discover_hosts --verbose Found 2 cell mappings. Skipping cell0 since it does not contain hosts. Getting computes from cell 'cell1' : 9b2d95a4-22da-4af4-8313-66f4d2f74680 Checking host mapping for compute host 'h3c-node01' : b1cc044a-841b-41fa-bbe0-ad07045ff46d Creating host mapping for compute host 'h3c-node01' : b1cc044a-841b-41fa-bbe0-ad07045ff46d Checking host mapping for compute host 'h3c-node02' : c4894695-8adf-4243-bc7f-9c950c6f9491 Creating host mapping for compute host 'h3c-node02' : c4894695-8adf-4243-bc7f-9c950c6f9491 Found 2 unmapped computes in cell: 9b2d95a4-22da-4af4-8313-66f4d2f74680
2. 创建实例超时 [错误: Build of instance 6ec6e8b1-9300-4be4-95fe-20434ea041f5 aborted: Volume e3dcad3d-dd22-4947-99d8-b8d0ad4b1025 did not finish being created even after we waited 187 seconds or 61 attempts. And its status is error.]
修改nove.conf中的重复尝试次数。参考[2.3.1 nove.conf](#2.3.1 nova.conf)。
3. 执行指令有warning 1 2 3 4 /usr/lib/python3/dist-packages/secretstorage/dhcrypto.py:15: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes /usr/lib/python3/dist-packages/secretstorage/util.py:19: CryptographyDeprecationWarning: int_from_bytes is deprecated, use int.from_bytes instead from cryptography.utils import int_from_bytes
将cryptography版本降至3.4以下，pip install cryptography==3.3.2
4. 无法在compute节点使用控制台 1 2 3 4 Error response Error code: 404 Message: File not found. Error code explanation: HTTPStatus.NOT_FOUND - Nothing matches the given URI.
方法1：将local.conf的NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"改为NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_lite.html"，但是需要重装该节点的openstack
方法2：将controller节点的vnc_lite.html复制为vnc_auto.html，==推荐==
1 root@controller:/opt/stack/noVNC
方法3：修改nova的配置文件，==该方法未验证==
5. 创建实例时报错，PortBindingFailed 1 PortBindingFailed: Binding failed for port 57ae0adc-89f9-41c6-afa7-cef5c19c6276, please check neutron logs for more information
在DashBoard的【管理员】-【系统】-【系统信息】-【网络代理】中发现对应的compute节点没有Open vSwitch agent，需要在local.conf中修改ENABLED_SERVICES参数，添加q-agt以启用该服务。需重新部署 该节点的openstack。
6. dpkg: error processing package rabbitmq-server 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Setting up rabbitmq-server (3.8.2-0ubuntu1.3) ...
