CentOS Stream 8 通过 Packstack 安装开源 OpenStack（V版）

news 2025/7/21 7:37:04

1、环境规划以及网卡配置

controller IP：192.168.235.101

compute IP：192.168.235.102

控制节点

[root@luck ~]# cd /etc/sysconfig/network-scripts/

[root@luck network-scripts]# vi ifcfg-ens160

[root@luck network-scripts]# cat ifcfg-ens160

TYPE=Ethernet

BOOTPROTO=none

NAME=ens160

DEVICE=ens160

ONBOOT=yes

IPADDR=192.168.235.101

NETMASK=255.255.255.0

GATEWAY=192.168.235.2

DNS1=192.168.235.2

计算节点

[root@luck ~]# cd /etc/sysconfig/network-scripts/

[root@luck network-scripts]# vi ifcfg-ens160

[root@luck network-scripts]# cat ifcfg-ens160

TYPE=Ethernet

BOOTPROTO=none

NAME=ens160

DEVICE=ens160

ONBOOT=yes

IPADDR=192.168.235.102

NETMASK=255.255.255.0

GATEWAY=192.168.235.2

DNS1=192.168.235.2

修改控制节点和计算节点主机名

[root@luck ~]# hostnamectl set-hostname controller ---控制节点

[root@luck ~]# hostnamectl set-hostname compute ---计算节点

2、关闭防火墙/selinux/networkmanager

注意:networkmanager,这个组件是在!inux8版本里面管理网络服务的(ip地址)，如果你提前把它关闭并禁用了，那么当节点重启的时候，是无法自动获取到ip地址的。

但是如果不关闭，它又会和 gpenstack,里面的 neutron 网络服务组件产生冲突。我们采用这种方式:暂时先不关闭networkmanager，等把所有环境全部安装好之后，再手工关闭和禁用 networkmanager，并使用 network来替换 networkmanager 这个服务。

控制节点关闭防火墙和selinux

[root@controller ~]# systemctl stop firewalld

[root@controller ~]# systemctl disable firewalld

Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@controller ~]# setenforce 0   临时关闭

[root@controller ~]# vi /etc/sysconfig/selinux  ---永久关闭

[root@controller ~]# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these three values:

#     targeted - Targeted processes are protected,

#     minimum - Modification of targeted policy. Only selected processes are protected.

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

或者永久关闭selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

计算节点关闭防火墙和selinux

[root@compute ~]# systemctl stop firewalld

[root@compute ~]# systemctl disable firewalld

Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@compute ~]# setenforce 0

[root@compute~]#sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

3、主机名映射及基础软件包

控制节点和计算节点都要映射

[root@controller ~]# echo '192.168.235.101 controller' >> /etc/hosts

[root@controller ~]# echo '192.168.235.102 compute' >> /etc/hosts

[root@controller ~]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.235.101 controller

192.168.235.102 compute

[root@controller ~]# yum install -y vim net-tools bash-completion chrony.x86_64 centos-release-openstack-victoria.noarch

4、配置时间服务器NTP

控制节点

[root@controller ~]# vim /etc/chrony.conf
server ntp.aliyun.com iburst
allow 192.168.100.0/24

重启时间服务器

[root@controller ~]# systemctl start chronyd.service
[root@controller ~]# systemctl enable chronyd

计算节点

[root@compute ~]# vim /etc/chrony.conf

server controller iburst

重启时间服务器

[root@compute ~]# systemctl start chronyd.service
[root@compute ~]# systemctl enable chronyd

5、配置YUM源

5.1 控制节点

[root@controller ~]# mkdir /etc/yum.repos.d/bak
[root@controller ~]# mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/

[root@compute ~]# cat /etc/yum.repos.d/cloudcs.repo

**** Installation completed successfully ******

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
* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
* File /root/keystonerc_admin has been created on OpenStack client host 192.168.235.101. To use the command line tools you need to source the file.
* To access the OpenStack Dashboard browse to http://192.168.235.101/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
* The installation log file is available at: /var/tmp/packstack/20240910-084808-673i1d3e/openstack-setup.log
