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
盘算节点
[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
修改控制节点和盘算节点主机名
[root@luck ~]# hostnamectl set-hostname controller ---控制节点
[root@luck ~]# hostnamectl set-hostname compute ---盘算节点
2、关闭防火墙/selinux/networkmanager
留意:networkmanager,这个组件是在!inux8版本里面管理网络服务的(ip地点)，如果你提前把它关闭并禁用了，那么当节点重启的时间，是无法自动获取到ip地点的。
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:临时先不关闭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来更换 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 ---永世关闭
[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
或者永世关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
盘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、主机名映射及底子软件包
控制节点和盘算节点都要映射
[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
盘算节点
[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

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 .
