| compute | 192.168.200.20 |
注；在此实验中所有密码的默认设置为000000，有需要可自己更改，自己把它记住，错了可别怪我没提醒~
初始化环境
基础配置
1，修改主机名
2，配置第一张网卡，且能联网
[root@controller ~]# ping www.baidu.com

3，配置主机映射（双节点执行）
[root@controller ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.10 controller
192.168.200.20 compute
[root@controller ~]#
[root@compute ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.10 controller
192.168.200.20 compute
[root@compute ~]#
4，关闭防火墙（双节点执行）
systemctl stop firewalld;systemctl disable firewalld
[root@controller ~]# systemctl stop firewalld;systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@controller ~]#
[root@compute ~]# systemctl stop firewalld;systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

5，关闭selinux，配置文件必须要重启后才生效，所以还要加上临时生效（双节点执行）
setenforce 0
[root@controller ~]# setenforce 0
[root@controller ~]# getenforce
Permissive
[root@controller ~]#
[root@compute ~]# setenforce 0
[root@compute ~]# getenforce

[root@controller ~]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.Enter current password for root (enter for none):
OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.Remove anonymous users? [Y/n] y... Success!Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] n... skipping.By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.Reload privilege tables now? [Y/n] y... Success!Cleaning up...All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.Thanks for using MariaDB!
搭建消息队列服务（控制节点执行）
安装软件包
yum install rabbitmq-server -y
启动并开机自启
systemctl enable rabbitmq-server.service;systemctl start rabbitmq-server.service
添加openstack用户并设置读写权限
rabbitmqctl add_user openstack 000000
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
[root@controller ~]# systemctl enable rabbitmq-server.service;systemctl start rabbitmq-server.service
[root@controller ~]# rabbitmqctl add_user openstack 000000
Creating user "openstack"
[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/"
[root@controller ~]#
缓存服务安装（控制节点执行）
安装缓存软件包
yum install memcached python-memcached -y
vi /etc/sysconfig/memcached
[root@controller ~]# cat /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,controller"
[root@controller ~]#
启动并开机自启服务
systemctl enable memcached.service;systemctl start memcached.service
etcd可不用配置，暂时用不到
！！！记住rabbitmq设置的openstack用户密码000000，后续都会用到
身份服务（控制节点执行）
配置数据库创建keystone用户并授权
mysql -u root -p000000
创建keystone数据库
CREATE DATABASE keystone;
授权远程权限，密码后续会用来做连接
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '000000';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '000000';
操作如下
MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.001 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.000 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '000000';
Query OK, 0 rows affected (0.000 sec)MariaDB [(none)]>
MariaDB [(none)]> exit
Bye
安装keystone包
yum install openstack-keystone httpd mod_wsgi -y
配置 /etc/keystone/keystone.conf文件，注意keystone数据库密码
vi /etc/keystone/keystone.conf
[database]
connection = mysql+pymysql://keystone:000000@controller/keystone[token]
provider = fernet
使用keystone用户执行keystone-manage db_sync命令
su -s /bin/sh -c "keystone-manage db_sync" keystone
The --keystone-user and --keystone-group flags are used to specify the operating system’s user/group that will be used to run keystone. These are provided to allow running keystone under another operating system user/group. In the example below, we call the user & group keystone.
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
Before the Queens release, keystone needed to be run on two separate ports to accommodate the Identity v2 API which ran a separate admin-only service commonly on port 35357. With the removal of the v2 API, keystone can be run on the same port for all interface，注意设置admin-pass密码
keystone-manage bootstrap --bootstrap-password 000000 \--bootstrap-admin-url http://controller:5000/v3/ \--bootstrap-internal-url http://controller:5000/v3/ \--bootstrap-public-url http://controller:5000/v3/ \--bootstrap-region-id RegionOne
配置httpd的/etc/httpd/conf/httpd.conf文件
vi /etc/httpd/conf/httpd.confServerName controller
演示如下
Create a link to the /usr/share/keystone/wsgi-keystone.conf file:
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
重启并开机自启
systemctl enable httpd.service;systemctl start httpd.service
注；如果报错没有权限，查看selinux是否关闭
和官网不同，这里直接设置管理员用户的变量，不设置临时变量。另外一个myuser用户脚本变量后续也用不到就不创建了
#!/bin/bash
#admin用户
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=000000
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
操作如下
[root@controller ~]# cat admin_openrch.sh
#!/bin/bash
#admin用户
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin

确定计算节点是否支持虚拟机的硬件加速：如果此命令返回一个或更大的值，则计算节点支持硬件加速，而硬件加速通常不需要额外的配置。如果此命令返回的值为零，则计算节点不支持硬件加速，并且必须配置/etc/nova/nova.conf下的libvirt以使用QEMU而不是KVM。
egrep -c '(vmx|svm)' /proc/cpuinfo

常见问题
本实验使用的是二层网络所以不要启动官网使用的neutron-l3-agent.service服务，这是三层网络，如果开启此服务，则需要配置驱动接口，不然会报错
2022-10-16 07:27:06.819 35159 INFO neutron.common.config [-] /usr/bin/neutron-l3-agent version 15.3.4
2022-10-16 07:27:07.126 35159 ERROR neutron.agent.l3.agent [-] An interface driver must be specified
需要配置接口驱动程序才能使用
vi /etc/neutron/l3_agent.ini [DEFAULT]
interface_driver = linuxbridgesystemctl enable neutron-l3-agent.service
systemctl start neutron-l3-agent.service
然后再开启相应的vxlan等网络模式，就能使用了
计算节点
安装软件包
yum install openstack-neutron-linuxbridge ebtables ipset -y
配置/etc/neutron/neutron.conf 文件
vi /etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@controller
#修改成自己设置的密码
auth_strategy = keystone[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS
#修改成自己设置的密码[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
具体配置如下
[DEFAULT]
transport_url = rabbit://openstack:000000@controller
auth_strategy = keystone[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = 000000[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
官网上这里是选择Provider networks模式
配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
#注意配置为自己的网卡名[vxlan]
enable_vxlan = false[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
以下具体配置直接追加到文件末尾
[linux_bridge]
physical_interface_mappings = provider:ens34[vxlan]
enable_vxlan = false[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
开启Linux操作系统内核支持网桥筛选器
加载br_netfilter内核模块
modprobe br_netfilter
配置/etc/sysctl.conf追加
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
启动生效配置
sysctl -p
演示如下
[root@compute ~]# modprobe br_netfilter
[root@compute ~]# vi + /etc/sysctl.conf
[root@compute ~]# sysctl -p
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
[root@compute ~]#
配置/etc/nova/nova.conf文件
vi /etc/nova/nova.conf
[neutron]
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = 000000
重启计算服务
systemctl restart openstack-nova-compute.service
启动并开机启动Linux网桥代理服务
systemctl enable neutron-linuxbridge-agent.service;systemctl start neutron-linuxbridge-agent.service
控制节点验证测试
openstack network agent list
演示如下
[root@controller ~]# openstack network agent list
