34.CentOS-Stream-8-packstack安装OpenStack-Victoria

CentOS-Stream-8-packstack安装OpenStack

前期准备

1、资源清单

CentOS-Stream-8(minimal安装) -CentOS-Stream-8-20240603.0-x86_64-dvd1.iso

https://mirrors.aliyun.com/centos-vault/8-stream/isos/x86_64/CentOS-Stream-8-20240603.0-x86_64-dvd1.iso?spm=a2c6h.25603864.0.0.33e24ee4AiZUTJ

vmware workstation17.5

OpenStack-Victoria

2、虚拟机硬件配置

controller 4CPU 8G内存 1张网卡:NAT 100G系统盘

compute 4CPU 8G内存 1张网卡:NAT 100G系统盘

按照个人情况配置内存

3、网络拓扑

vmware网络设置：

NAT网络,开启DHCP，192.168.108.0/24，网关192.168.108.2，DNS 192.168.108.2

说明：

Windows环境vmware的NAT网络网关为192.168.108.2

Linux环境vmware的NAT网络网关为192.168.108.1

/etc/hosts

192.168.108.10 controller

192.168.108.11 compute

步骤一：准备模板虚拟机

基于CentOS-Stream-8模板制作.md制作的模板，克隆出一个虚拟机(openstack_template)，作为openstack模板虚拟机

完整克隆，克隆好后，开机配置

配置yum源

EOF[root@localhost ~]# yum clean all

[root@localhost ~]# yum makecache

安装方便操作环境包及基础软件包

[root@localhost ~]# yum install -y bash-completion vim open-vm-tools net-tools chrony.x86_64
[root@localhost ~]# source /usr/share/bash-completion/bash_completion

设置/etc/hosts

[root@localhost ~]# echo '192.168.108.10 controller' >> /etc/hosts
[root@localhost ~]# echo '192.168.108.11 compute' >> /etc/hosts

关闭SELinux

[root@localhost ~]# sed -i '/^SELINUX=/cSELINUX=disabled' /etc/selinux/config

编辑网卡信息

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# vim ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=ens160
DEVICE=ens160
ONBOOT=yes

清除密钥信息

[root@localhost ~]# cd /etc/ssh/
[root@localhost ssh]# rm -rf ssh_host_*

清除Machine ID

[root@localhost ~]# cat /dev/null > /etc/machine-id 
[root@localhost ~]# cat /etc/machine-id

关闭操作系统并拍快照。

[root@localhost ~]# poweroff 

---

步骤二：准备openstack节点

克隆虚拟机并修改基础配置

采用完全克隆方法克隆出其他2台虚拟机（openstack-controller , openstack-compute）。

同样的操作克隆计算节点

2节点的CPU需要开启虚拟化支持。

两节点配置不同的IP，主机名

两节点分别开机，做以下配置

配置主机名

controller:

[root@localhost ~]# hostnamectl set-hostname controller

compute:

[root@localhost ~]# hostnamectl set-hostname compute

配置IP地址

controller:

[root@controller ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none    #从dhcp转变为none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.108.10
NETMASK=255.255.255.0
GATEWAY=192.168.108.2
DNS1=192.168.108.2
[root@controller ~]# nmcli connection down ens160
[root@controller ~]# nmcli connection up ens160

compute:

[root@compute ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.108.11
NETMASK=255.255.255.0
GATEWAY=192.168.108.2
DNS1=192.168.108.2
[root@controller ~]# nmcli connection down ens160
[root@controller ~]# nmcli connection up ens160

配置NTP

controller:

[root@controller ~]# vim /etc/chrony.conf
# pool 2.centos.pool.ntp.org iburst
server ntp.aliyun.com iburst# Allow NTP client access from local network.
#allow 192.168.0.0/16
allow 192.168.108.0/24#启动服务
[root@controller ~]# systemctl restart chronyd
[root@controller ~]# systemctl enable chronyd

compute:

[root@compute ~]# vim /etc/chrony.conf
# pool 2.centos.pool.ntp.org iburst
server controller iburst#启动服务
[root@compute ~]# systemctl restart chronyd
[root@compute ~]# systemctl enable chronyd

重启下操作系统

controller:

[root@controller ~]# reboot

compute:

[root@compute ~]# reboot

此处建议关机拍摄快照

步骤三：安装OpenStack和测试

控制节点安装packstack

controller:

[root@controller ~]# yum install -y openstack-packstack

生成应答文件

controller:

[root@controller ~]# packstack --gen-answer-file=answers.txt
Packstack changed given value  to required value /root/.ssh/id_rsa.pub
Additional information:* Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS plugin. Geneve will be used as the encapsulation method for tenant networks

更改应答文件

controller:

[root@controller ~]# sed -i '/^CONFIG_COMPUTE_HOSTS=/cCONFIG_COMPUTE_HOSTS=192.168.108.10,192.168.108.11' answers.txt
[root@controller ~]# sed -i '/^CONFIG_PROVISION_DEMO=/cCONFIG_PROVISION_DEMO=n' answers.txt
[root@controller ~]# sed -i '/^CONFIG_HEAT_INSTALL=/cCONFIG_HEAT_INSTALL=y' answers.txt
[root@controller ~]# sed -i '/^CONFIG_NEUTRON_OVN_BRIDGE_IFACES=/cCONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens160' answers.txt
[root@controller ~]# sed -i.bak -r 's/(.+_PW)=[0-9a-z]+/\1=huawei/g' answers.txt

关闭NetworkManager

controller:

[root@controller ~]# systemctl stop NetworkManager; systemctl disable NetworkManager; systemctl mask NetworkManager

compute:

[root@compute ~]# systemctl stop NetworkManager; systemctl disable NetworkManager; systemctl mask NetworkManager

CentOS 8 版本默认使用 NetworkManager 管理网络，但它会和 openstack 网络组件产生冲突，从而导致告警或错误

根据应答文件配置安装openstack

controller:

[root@controller ~]# packstack --answer-file=answers.txt

安装过程中，会在Testing if …controller.pp步骤停留很长时间，预计40-50分钟，其他步骤很快。

安装完成

登录测试

开启network服务

controller:

[root@controller ~]# systemctl start network
[root@controller ~]# systemctl enable network
network.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable network

compute:

[root@compute ~]# systemctl start network
[root@compute ~]# systemctl enable network
network.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable network

配置OpenStack命令补全

#将命令写入到/etc/bash_completion.d/，路径一定要写正确
[root@controller ~]# openstack complete >> /etc/bash_completion.d/complete
The 'openstack bgp speaker show dragents' CLI is deprecated and will be removed in the future. Use 'openstack bgp dragent list' CLI instead.
[root@controller ~]# reboot

关机拍快照

openstack_controller和openstack_compute两个拍摄快照

至此安装结束
