一、先决条件
### --- 先决条件
### --- BS结构的访问体系
~~~ 安装OpenStack compute(nova)和identity(keystone)service
~~~ 安装Python2.6或2.7，并必须支持Django（增加了一套网页模板）
~~~ 你的浏览器必须支持HTML5并启用cookies和JavaScript功能（常规浏览器都支持）二、代码构建（在openstack-controller节点部署）
### --- 检查环境是否正常

~~~ 4个工具，48个包二、配置仪表盘
### --- 编辑/etc/openstack-dashboard/local_settings文件并完成下列配置
[root@controller ~]# vim /etc/openstack-dashboard/local_settings
# 配置dashboard使用controller节点上的OpenStack服务
OPENSTACK_HOST = "controller.nice.com" # 告诉它本机地址是
ALLOWED_HOSTS = ['controller.nice.com', '*'] # 设置主机地址，只允许本地访问localhost改为*号，全局访问
# 设置允许来自所有网络的主机访问dashboard
ALLOWED_HOSTS=['*']
# 配置memcached会话存储服务（将原有CACHES区域注释）
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '127.0.0.1:11211', # 地址是127.0.0.1:11211
} # Python中空格是有严格限制的，注意
}
# (可选）配置时区
TIME_ZONE="TIME_ZONE"
# 地球人一般设置成：
TIME_ZONE = "Asia/Shanghai" # 设置时区为亚洲上海三、完成安装
### --- 在RHEL或CentOS上，配置SElinux去允许web服务器访问OpenStack服务（如果你没关SElinux）：
~~~ 此环境已关闭了selinux，不执行
[root@controller ~]# setsebool -P httpd_can_network_connect on ### --- 修改相关文件归属，使dashboard CSS可以被加载
~~~ 修改网页文件的属主属组权限
[root@controller ~]# chown -R apache:apache /usr/share/openstack-dashboard/static ### --- 启动web服务和会话保存服务，并设置开机自动启动。
[root@controller ~]# systemctl enable httpd.service memcached.service
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
ln -s '/usr/lib/systemd/system/memcached.service' '/etc/systemd/system/multi-user.target.wants/memcached.service'
[root@controller ~]# systemctl start httpd.service memcached.service
[root@controller ~]# systemctl status httpd.service memcached.service四、修改本地电脑的hosts文件
### --- 添加解析地址
C:\Windows\System32\drivers\etchosts
192.168.222.5 controller.nice.com 五、验证：http://controller.nice.com/dashboard
### --- 访问dashboard，在浏览器输入：http://controller.nice.com/dashboard
~~~ (建议Chrome浏览器访问）
### --- 使用admin或demo用户登录
~~~ 用户名：admin
~~~ 密码：ADMIN_PASS
仪表盘套件
附录一：故障解决
### --- 报错现象
~~~ 检查构建环境发现nova-compute服务down的重新启动服务即可
[root@controller ~]# source admin-openrc.sh
[root@controller ~]# nova service-list
+----+------------------+---------------------+----------+---------+-------+----------------------------+-----------------+
| Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |

| 5 | nova-compute | compute1.nice.com | nova | enabled | down | 2021-01-11T16:30:53.000000 | - |
+----+------------------+---------------------+----------+---------+-------+----------------------------+-----------------+### --- 解决方案:
[root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
[root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.serviceWalter Savage Landor:strove with none,for none was worth my strife.Nature I loved and, next to Nature, Art:I warm'd both hands before the fire of life.It sinks, and I am ready to depart
