openstack【Kilo】入门 【keystone篇】六：创建服务实例和 API endpoint

问题导读

1.这里配置的OS_TOKEN的作用是什么？
2.如何创建服务实例和API endpoint？




1.准备

1.配置token
[mw_shl_code=bash,true] export OS_TOKEN=ADMIN_TOKEN[/mw_shl_code]

给ADMIN_TOKEN赋值，这个指是上篇生成的，比如是294a4c8a8a475f9b9836
[mw_shl_code=bash,true]export OS_TOKEN=294a4c8a8a475f9b9836[/mw_shl_code]

2.配置 endpoint URL:
[mw_shl_code=bash,true]export OS_URL=http://controller:35357/v2.0[/mw_shl_code]

2.创建服务实例和API endpoint

1.创建Identity 实例服务:

[mw_shl_code=bash,true]openstack service create \
  --name keystone --description "OpenStack Identity" identity[/mw_shl_code]



2.创建实例服务
[mw_shl_code=bash,true]openstack endpoint create \
  --publicurl http://controller:5000/v2.0 \
  --internalurl http://controller:5000/v2.0 \
  --adminurl http://controller:35357/v2.0 \
  --region RegionOne \
  identity

[/mw_shl_code]

root@controller:/var/www/cgi-bin/keystone# openstack --debug  service create   --name keystone --des ...

openstack service create   --name keystone --description "OpenStack Identity" identity
出现InternalServerError: Internal Server Error (HTTP 500)
应该是/var/www/cgi-bin/keystone/admin 以及main有问题
官网下载的不行，
在/usr/share/keystone/下有文件wsgi.py 把其中内容cp到admin 和 main中，解决
你可以试试

楼主~我按照文档一步一步，出现这个问题
root@controller:~# openstack service create --name keystone --description "OpenStack Identity" identity
ERROR: openstack An unexpected error prevented the server from fulfilling your request. (HTTP 500) (Request-ID: req-243b80d8-afc2-4645-907d-fab27860e19f)

前面安装步骤有问题。

大神，可以告诉我哪里有问题吗？因为我是按照文档一步一步操作的

openstack An unexpected error prevented

上面错误只能定位到keystone是有问题的，详细看看日志，能否定位到。不行就多装几次，不过下次可能遇到其它问题。
总之安装过程中细心，应该不会出现问题

自己摸索的话，可能时间比较长一些，推荐下面视频，都是跟这些文档配套的
