1. OpenStack-Dashboard component deployment

1.1. Install httpd on C1 node

[root@c1 ~]# yum -y install openstack-dashboard httpd
#在CT控制节点已安装httpd服务，而Dashboard控制台也需要httpd支持，所以此处可以在C1节点进行安装httpd

1.2, modify the local_setting configuration file of the local console

[root@c1 ~]# cd /etc/openstack-dashboard/
[root@c1 openstack-dashboard]# ls
cinder_policy.json  glance_policy.json  keystone_policy.json  local_settings  neutron_policy.json  nova_policy.d  nova_policy.json
[root@c1 openstack-dashboard]# vim local_settings 
#修改local_setting本地控制台的配置文件
import os								#使用Python导入一个模块
from django.utils.translation import ugettext_lazy as _
from openstack_dashboard.settings import HORIZON_CONFIG
DEBUG = False							#不开启调式	
ALLOWED_HOSTS = ['*']						#只允许通过列表中指定的域名访问dashboard；允许通过指定的IP地址及域名访问dahsboard；
								['*']表示允许所有域名
LOCAL_PATH = '/tmp'
SECRET_KEY='742dea092013cc0a2dfc'
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'		#指定session引擎
CACHES = {
    
    							#95-100行取消"#"注释
    'default': {
    
    
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'ct:11211',	#指定memcache地址及端口
    }
}
#以下配置session信息存放到memcache中；session信息不仅可以存放到memcache中，也可以存放到其他地方
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'		#108行修改
OPENSTACK_HOST = "ct"						#118-127行修改
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST	
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True			#让dashboard支持域
OPENSTACK_API_VERSIONS = {
    
    
    "identity": 3,
    "image": 2,
    "volume": 3,
}
#配置openstack的API版本
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
OPENSTACK_NEUTRON_NETWORK = {
    
    					#132行到152行修改
    'enable_auto_allocated_network': False,
    'enable_distributed_router': False,

1.3, restart the service

[root@c1 openstack-dashboard]# python manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf
[root@c1 openstack-dashboard]# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@c1 openstack-dashboard]# systemctl restart httpd.service
#重新生成openstack-dashboard.conf并重启Apache服务
（由于dashborad会重新复制代码文件，重启apache会比较慢）

1.4. Restart the memcache service of the ct node

[root@ct ~]# systemctl restart memcached.service

1.5, verification operation

Open the browser, enter "http://192.168.74.12" (node IP of C1) in the address bar, enter the Dashboard
login page and fill in the login page in turn: "Domain: default, username: admin, password: ADMIN_PASS" ( (Defined in ~.bashrc)
after completion, log in
