安装horizon

在控制节点上安装

controllerHost='controller'
ADMIN_PASSWD='Ideal123!'

1.安装dashboard组件

yum -y install openstack-dashboard

sed -i "/ALLOWED_HOSTS =/cALLOWED_HOSTS = ['*']"  /etc/openstack-dashboard/local_settings

sed -i '/^#OPENSTACK_API_VERSIONS/iOPENSTACK_API_VERSIONS = {"data-processing": 1.1,
"identity": 3,
"image": 2,
"volume": 2,
"compute": 2}' /etc/openstack-dashboard/local_settings

4.配置dashboard使用memcached缓存session，注释掉其它的缓存配置

line_index=$(sed -n -e "/^CACHES/=" /etc/openstack-dashboard/local_settings)
sed -i "${line_index},+5d" /etc/openstack-dashboard/local_settings
sed -i "${line_index} a CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '${controllerHost}:11211' }}" /etc/openstack-dashboard/local_settings
sed -i 's/^SESSION_ENGINE/#&/' /etc/openstack-dashboard/local_settings
echo "SESSION_ENGINE = 'django.contrib.sessions.backends.cache'" >> /etc/openstack-dashboard/local_settings

5.配置dashboard得知keystone服务的地址

sed -i "/OPENSTACK_HOST =/cOPENSTACK_HOST = '${controllerHost}'"  /etc/openstack-dashboard/local_settings
sed -i '/^OPENSTACK_KEYSTONE_URL/cOPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST' /etc/openstack-dashboard/local_settings

6.配置dashboard启用对多域的支持，在登陆的时候需要输入域

sed -i "/OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT =/cOPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True" /etc/openstack-dashboard/local_settings

7.配置dashboard中创建的用户都属于Default域

sed -i "/OPENSTACK_KEYSTONE_DEFAULT_DOMAIN =/cOPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'" /etc/openstack-dashboard/local_settings

8.配置dashboard中创建的用户都是user角色

sed -i '/OPENSTACK_KEYSTONE_DEFAULT_ROLE =/cOPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"'  /etc/openstack-dashboard/local_settings

9.配置dashboard中的时区

sed -i '/TIME_ZONE =/cTIME_ZONE = "Asia/Shanghai"'   /etc/openstack-dashboard/local_settings

10.配置httpd使用WSGI运行python程序

sed -i '/WSGISocketPrefix/aWSGIApplicationGroup %{GLOBAL}'   /etc/httpd/conf.d/openstack-dashboard.conf

11.配置httpd服务的监听IP

sed -i "s/Listen 80/Listen 0.0.0.0:80/g" /etc/httpd/conf/httpd.conf

12.启动dashboard服务

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

dashboard报错处理

1.登陆页面，无法跳转

sed -i 's/^SESSION_ENGINE/#&/' /etc/openstack-dashboard/local_settings
echo "SESSION_ENGINE = 'django.contrib.sessions.backends.file'" >> /etc/openstack-dashboard/local_settings
systemctl restart httpd memcached && systemctl status httpd memcached

2.出错啦！ 遇到异常情况，请刷新

systemctl restart rabbitmq-server && systemctl status rabbitmq-server
