部署dashboard

1. 部署说明

部署地点： 控制节点（ip:192.168.0.142)。

2. 安装组件

yum install -y openstack-dashboard

3. 配置dashboard

3.1. 配置local_settings

cp /etc/openstack-dashboard/local_settings /etc/openstack-dashboard/local_settings.bac

在/etc/openstack-dashboard/local_settings中配置以下内容。

OPENSTACK_HOST = "controller"

ALLOWED_HOSTS = ['*',]


SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': 'controller:11211',
    },
}

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 3,
}

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

如果您选择网络选项 1，请禁用对第 3 层网络服务的支持：

OPENSTACK_NEUTRON_NETWORK = {
    'enable_distributed_router': False,
    'enable_firewall': False,
    'enable_ha_router': False,
    'enable_lb': False,
    'enable_quotas': True,
    'enable_security_group': True,
    'enable_vpn': False,
    'profile_support': None,
}

增加以下配置，否则dashboard的权限配置policy.json不生效, 界面显示的栏目也不对, 还经常弹出错误。

keystone定义了每个用户的权限, 所以原来界面栏目显示混乱。

POLICY_FILES_PATH = '/etc/openstack-dashboard'

3.2. openstack-dashboard-18.3.3-1及以前的版本配置

注意openstack-dashboard-18.3.3-2及以后的版本无需做以下配置，openstack-dashboard-18.3.3-1及以前的版本需要做如下配置。

配置/etc/httpd/conf.d/openstack-dashboard.conf：

cp /etc/httpd/conf.d/openstack-dashboard.conf /etc/httpd/conf.d/openstack-dashboard.conf.bac

tee /etc/httpd/conf.d/openstack-dashboard.conf <<-'EOF'
#WSGIDaemonProcess dashboard
#WSGIProcessGroup dashboard
#WSGISocketPrefix run/wsgi
#WSGIApplicationGroup %{GLOBAL}
#
#WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
#Alias /static /usr/share/openstack-dashboard/static
#
#<Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi>
#Options All
#AllowOverride All
#Require all granted
#</Directory>
#
#<Directory /usr/share/openstack-dashboard/static>
#Options All
#AllowOverride All
#Require all granted
#</Directory>
#EOF

4. 重启服务

systemctl restart httpd.service memcached.service
systemctl status httpd.service memcached.service
