7.1.安装dashboard WEB控制台
1)安装dashboard软件包
yum install openstack-dashboard -y
2)修改配置文件/etc/openstack-dashboard/local_settings
# 检查确认有以下配置
vim /etc/openstack-dashboard/local_settings ------------------------------------- ALLOWED_HOSTS = ['*', ] SESSION_ENGINE = 'django.contrib.sessions.backends.cache' OPENSTACK_API_VERSIONS = { "identity": 3, "image": 2, "volume": 2, } OPENSTACK_HOST = "controller" OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default" CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': 'controller:11211', } } OPENSTACK_NEUTRON_NETWORK = { 'enable_router': False, 'enable_quotas': False, 'enable_distributed_router': False, 'enable_ha_router': False, 'enable_fip_topology_check': False, 'enable_lb': False, 'enable_firewall': False, 'enable_vpn': False, } TIME_ZONE = "Asia/Shanghai" --------------------------------------
# 配置选项:
配置dashboard运行在192.168.1.81上(192.168.1.81为OS主机名)
配置允许登陆dashboard的主机
配置memcached存储服务
启用第3版认证API
启用对域的支持
配置API版本
通过仪表盘创建用户时的默认域配置为 default
通过仪表盘创建的用户默认角色配置为 user
如果您选择网络参数1,禁用支持3层网络服务:
可以选择性地配置时区,不能用CST否则无法启动httpd服务
3)修改/etc/httpd/conf.d/openstack-dashboard.conf
# 增加以下内容
vim /etc/httpd/conf.d/openstack-dashboard.conf ------------------------------------- WSGIApplicationGroup %{GLOBAL} -------------------------------------
4)重启web服务器以及会话存储服务
systemctl restart httpd.service memcached.service
systemctl status httpd.service memcached.service
5)检查dashboard是否可用
# 在浏览器中输入下面的地址:用户名 admin 和密码之前创建为 123456(keystone 创建),域名用 default
http://controller:80/dashboard
# 浏览器页面如下:
# 登录后显示这样一个摘要信息:
# 新安装的默认里面基本是空的,需要后续手动添加扩充
6)其他可选的dashboard配置
