1) 安装openstack-dashboard 组件
yum install openstack-dashboard -y
2) 修改local_settings 配置文件
vi /etc/openstack-dashboard/local_settings
①可以查找到的文件
OPENSTACK_HOST = “192.168.186.133”
ALLOWED_HOSTS = [‘192.168.186.133’,‘192.168.186.137’,‘127.0.0.1’] ----修改为自己的ip
SESSION_ENGINE = ‘django.contrib.sessions.backends.cache’
CACHES = {
‘default’: {
 ‘BACKEND’: ‘django.core.cache.backends.memcached.MemcachedCache’,
 ‘LOCATION’: ‘192.168.186.133:11211’, -------修改为主机ip
},
}
OPENSTACK_KEYSTONE_URL = “http://%s:5000/v3” % OPENSTACK_HOST
②需要在最后添加的
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
“identity”: 3,
“image”: 2,
#“volume”: 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = “Default”
OPENSTACK_KEYSTONE_DEFAULT_ROLE = “user”
-------------如何配置的是self-service网络，则不需要配置---------------
#OPENSTACK_NEUTRON_NETWORK = {
#
# ‘enable_router’: False,
# ‘enable_quotas’: False,
# ‘enable_distributed_router’: False,
# ‘enable_ha_router’: False,
#‘enable_lb’: False,
#‘enable_firewall’: False,
#‘enable_vpn’: False,
#‘enable_fip_topology_check’: False,
#}
-----------------------------------
TIME_ZONE = “UTC” ---------时区根据自己的时间组件选取
3）修改openstack-dashboard.conf配置文件
vi /etc/httpd/conf.d/openstack-dashboard.conf
WSGIApplicationGroup %{GLOBAL} ---------添加在文件前面一部分
4) 启动服务，并验证
systemctl restart httpd.service memcached.service
systemctl status httpd.service memcached.service
192.168.186.133/dashboard
openstackComputer----------------配置
1. nova安装配置
https://docs.openstack.org/nova/queens/install/compute-install-rdo.html
1) 编辑两个源，方便下载nova组件
cd /etc/yum.repos.d/
curl -O https://trunk.rdoproject.org/centos7/delorean-deps.repo
curl -O https://trunk.rdoproject.org/centos7/current-passed-ci/delorean.repo
2) 更新yum中的文件并重启
yum update -y
yum repolist enabled
reboot
3) 安装openstack-nova-compute组件
yum install openstack-nova-compute -y
4) 编写nova.conf，进行相关配置
vi /etc/nova/nova.conf
vi /etc/nova/nova.conf
[DEFAULT]
enabled_apis=osapi_compute,metadata
transport_url=rabbit://openstack:openstack@192.168.186.133
[api_database]
connection=mysql+pymysql://nova:nova@192.168.186.133/nova_api
[database]
connection=mysql+pymysql://nova:nova@192.168.186.133/nova
[api]
auth_strategy = keystone
[keystone_authtoken]
#auth_uri=http://192.168.186.133:5000/v3
auth_url=http://192.168.186.133:5000/v3
mamcached_servers=192.168.186.133:11211

project_domain_name=Default
user_domain_name=Default
project_name=service
username=nova
password=nova
[DEFAULT]
my_ip=192.168.186.133 -----------------使用控制节点的ip
use_neutron=True
firewall_driver=nova.virt.firewall.NoopFirewallDriver
[vnc] ---------------与控制节点不同
enabled = true
server_listen=0.0.0.0
server_proxyclient_address=$my_ip
novncproxy_base_url=http://192.168.186.133:6080/vnc_auto.html
[glance]
api_servers=http://192.168.186.133:9292
[oslo_concurrency]

user_domain_name=Default
auth_url=http://192.168.186.133:5000/v3
username=placement
password=placement
5) 解决不支持虚拟化的问题
①检查并解决
egrep -c ‘(vmx|svm)’ /proc/cpuinfo -------0 ------本机没有虚拟环境
vi /etc/nova/nova.conf
[libvirt]
# …
virt_type = qemu ------------
② 启动libvirtd服务
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service
6) 在controller进行注册操作
openstack compute service list --service nova-compute
nova-manage cell_v2 discover_hosts
2.neutron安装配置
1) 安装三个相关的服务
yum install openstack-neutron-linuxbridge ebtables ipset -y
2）编写neutron.conf配置文件
vi /etc/neutron/ neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.186.133
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://192.168.186.133:5000
auth_url = http://192.168.186.133:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:ens33 -----------不确定
[vxlan]
enable_vxlan = true
local_ip = 192.168.186.137 -------------应该是对的
l2_population = true
[securitygroup]
# …
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
3）编写nova.conf配置文件
vi /etc/nova/nova.conf
[neutron]
# …
url = http://192.168.186.133:9696
auth_url = http://192.168.186.133:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
