CRITICAL keystonemiddleware.auth_token  Unable to validate token: Identity server rejected authorization necessary to fetch token data

解决办法：

1）确认XXX.conf中的keystone_authtoken配置是否正确，主要检查用户名、密码、工程名等。

2）问题依旧未解决，必须查看keystone的日志进一步确认。

我在排查问题时犯了一个严重的错误，想当然的认为配置就是对的，忙糊涂啦。

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

解决办法：

for scrapy with Python 3, you'll need

sudo apt-get install python3 python-dev python3-dev \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

with Python 2, you'll need

sudo apt-get install python-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

$ curl 127.0.0.1:9200
curl: (52) Empty reply from server

解决办法：

docker container 的/etc/hosts不能配置127.0.0.1 或者192.168.0.1

否则宿主机器将无法访问端口
